The core B2B SaaS CAC benchmarks for 2026: a CAC payback period under about 18 months (median near 16), an LTV/CAC ratio of 3:1 or better, a SaaS magic number above 0.75, and a burn multiple below 2 for venture-stage companies and below 1 as you scale. These are directional targets, not laws.
Every one of them moves with contract size, go-to-market (GTM) motion, and company stage, so the right benchmark for an enterprise platform selling six-figure deals looks nothing like the right one for a self-serve product at $60 a seat.
What follows is a working reference for each of those metrics: the precise formula, the benchmark with its named source and year, how to read it, and how to move it. Where the published data disagrees — and it often does — we show the range and say so plainly. The numbers here come from full-year 2025 actuals and the most recent 2024–2026 benchmark studies, but treat them as a starting line for setting your own targets, not a scoreboard to grade yourself against in isolation.
The efficiency era reset the benchmarks
The benchmarks most operators memorized before 2022 no longer describe the market they sell into. The zero-interest-rate years rewarded growth almost without regard to its cost; capital was cheap, so a long payback period and a heavy burn were survivable, even fashionable. That era ended. The clearest symbol of the turn is the source of the numbers themselves: OpenView Partners, whose annual SaaS Benchmarks Report was the field’s reference document for the better part of a decade, abruptly halted new investments in December 2023 and wound down its investing operation, as reported by The Information, Forbes, and Axios. Stewardship of the report passed to High Alpha, which has continued it — its 2025 edition drew on more than 800 survey respondents — but the handoff itself marked the close of one chapter of SaaS benchmarking and the opening of another defined by capital discipline.
The efficiency reset shows up in the data. The SaaS magic number — a direct measure of sales-and-marketing productivity — had a median of 0.94 in 2024, below the 1.0 line that separates efficient from inefficient spending, according to the 2026 SaaS & AI Performance Benchmarks published by Aleph and Benchmarkit (full-year 2025 actuals, 342 companies). By 2025 that median had climbed to 1.37, the first time the population crossed 1.0 in the series. CAC payback moved the same direction: Aleph and Benchmarkit report the median improved from 18 months in 2024 to 16 months in 2025, the largest single-year gain in four years. Companies did not get more efficient by accident. They cut low-return spend, lengthened sales cycles they could afford to lengthen, and concentrated budget on channels that paid back. The benchmarks below reflect that recalibrated market, which is why the older 12-month payback rule of thumb now reads as best-in-class rather than typical.
Customer acquisition cost (CAC): blended, paid, and fully-loaded
Customer acquisition cost is the total cost of winning a new customer, divided by the number of new customers won in the same period. The formula is simple; the definition of “total cost” is where operators mislead themselves. Three versions circulate, and they are not interchangeable.
- Paid CAC counts only media spend — the ad dollars in paid search, paid social, and display — divided by customers acquired through those channels. It is the cleanest read on channel efficiency and the number your media buyer should live by.
- Blended CAC divides all sales-and-marketing cost by all new customers, including those who arrived through organic search, referrals, and word of mouth. It flatters you, because free customers pull the average down, but it is the honest number for board-level capital-efficiency questions.
- Fully-loaded CAC adds the salaries, commissions, tooling, and overhead of the sales and marketing teams to the media spend. This is the version that maps to your P&L and the one that drives payback and LTV/CAC. If you quote a CAC without saying which of the three you mean, you are quoting a number no one can act on.
Rather than a single dollar figure — which is meaningless without knowing your ACV — the more useful benchmark is the CAC ratio: the cost to acquire a dollar of new annual recurring revenue. Benchmarkit’s 2025 report puts the median new-customer CAC ratio at $2.00 (a 2024 actual reported in the 2025 report), meaning the median company spent two dollars of fully-loaded sales and marketing to win one dollar of new-customer ARR — a 14% increase from 2023, reflecting how much harder acquisition became through the downturn. The fourth (worst) quartile sat at $2.82 at its median. Benchmarkit also notes the ratio varies sharply by contract size: deals above $100K in annual contract value showed lower CAC ratios than the $10K–$100K band, and blended CAC ratios were roughly 10% higher in 2024 than in 2022.
| CAC ratio (fully-loaded S&M per $1 of new ARR) | Benchmark | Source (year) |
|---|---|---|
| New-customer CAC ratio, median | $2.00 | Benchmarkit, 2025 |
| New-customer CAC ratio, 4th quartile median | $2.82 | Benchmarkit, 2025 |
| Change in median new-customer CAC ratio vs. 2023 | +14% | Benchmarkit, 2025 |
| Blended CAC ratio vs. 2022 | ~10% higher | Benchmarkit, 2025 |
To improve CAC, the levers are the ones that either lower the cost of the motion or raise the yield of it: tightening targeting so media reaches accounts that can actually close, improving landing-page and funnel conversion so the same traffic produces more customers, shifting mix toward channels with lower paid CAC, and lifting win rates through better sales enablement. A disciplined conversion optimization program is often the fastest lever, because it lowers CAC without touching media budget at all — you are simply paying for the same clicks and converting more of them.
CAC payback period: the cash-flow metric
CAC payback is the number of months a customer must stay before the gross profit they generate repays what you spent to acquire them. The standard formula divides fully-loaded CAC by the monthly recurring revenue a customer produces, adjusted for gross margin:
CAC payback (months) = CAC ÷ (monthly recurring revenue per customer × gross margin)
Some operators, including First Page Sage in the report cited below, use a simpler CAC-divided-by-monthly-recurring-revenue version that omits the gross-margin adjustment. The margin-adjusted version is the more conservative and the one investors expect, so know which you are reporting. Payback matters because it is a cash-flow metric, not a profitability metric: it tells you how long your capital is tied up before a customer becomes self-funding, which is what determines how fast you can grow without running out of money.
The headline benchmark: the 2026 Aleph and Benchmarkit report puts the 2025 median CAC payback at 16 months, with the top quartile at 6 months or less and the bottom quartile at 24 months or more; the worst cases stretched to 48 months. Their working thresholds are “good” under 18 months and “top-tier” under 12 months. But the segment variance is enormous, which is why a single median is close to useless for target-setting.
| Segment | Average payback (months) | “Good” payback (months) |
|---|---|---|
| Consumer | 4–10 | 1–7 |
| SMB | 8–19 | 4–11 |
| Middle market | 11–24 | 8–19 |
| Enterprise | 14–31 | 11–24 |
The table above is from First Page Sage’s 2025 SaaS CAC Payback Benchmarks, drawn from their work with more than 50 SaaS companies across 25+ industries. Read it as the correction to the single-number median: an enterprise company at 22 months is performing well for its segment, while an SMB company at 22 months is in trouble. Aleph and Benchmarkit’s 2025 cut by contract size tells the same story from a different angle — sub-$5K ACV companies posted an 11-month median payback, while $50K–$100K deals ran to a 22-month median. Curiously, Benchmarkit notes that the very largest deals (above $250K ACV) showed materially lower payback than the $50K–$100K band, because the biggest contracts often close through relationship-led motions with proportionally lower acquisition cost per dollar of ARR.
| Cut | Median CAC payback (months) | Source (year) |
|---|---|---|
| Overall population | 16 | Aleph & Benchmarkit, 2025 actuals |
| Overall, 2024 (prior year) | 18 | Aleph & Benchmarkit, 2024 actuals |
| Sub-$5K ACV | 11 | Aleph & Benchmarkit, 2025 |
| $50K–$100K ACV | 22 | Aleph & Benchmarkit, 2025 |
| >50% growth companies | 10 | Aleph & Benchmarkit, 2025 |
| Horizontal SaaS | 14 | Aleph & Benchmarkit, 2025 |
| Vertical SaaS | 18 | Aleph & Benchmarkit, 2025 |
Improving payback means either lowering CAC or raising the monthly value and margin of what you sell. Annual prepaid contracts collapse payback dramatically because the cash arrives up front; moving customers from monthly to annual billing is one of the highest-leverage changes available and touches no acquisition cost at all. Higher gross margins, expansion revenue that lifts per-customer MRR early in the relationship, and the CAC levers above all pull payback down. Sound conversion optimization for B2B shortens payback on the acquisition side; pricing and packaging work shortens it on the revenue side.
LTV/CAC ratio: the return on acquisition
The LTV/CAC ratio compares the lifetime value of a customer to the cost of acquiring them. Lifetime value is the gross-margin-adjusted revenue you expect over the customer’s life, usually calculated as average revenue per customer times gross margin divided by the churn rate; dividing that by CAC gives you the return multiple on each acquisition dollar.
LTV = (average revenue per customer × gross margin) ÷ churn rate; LTV/CAC = LTV ÷ CAC
The convention most widely cited is a target of 3:1 or better — three dollars of lifetime gross profit for every dollar of acquisition cost. The Optifai Pipeline Study (2026, 939 B2B SaaS companies) reports a median LTV/CAC of 3.2:1, a target floor of 3:1, a healthy band of 3–5:1, and excellent efficiency above 5:1. The logic behind the 3:1 floor: below it, the return does not adequately cover the operating costs, gross-margin erosion, and risk that sit between revenue and profit; much above 5:1, and you are likely under-investing in growth — a very high ratio often means you could profitably spend more on acquisition than you are.
| LTV/CAC ratio | Interpretation |
|---|---|
| Below 1:1 | You lose money on every customer; the model is broken |
| 1:1 to 3:1 | Under target; acquisition return too thin to be durable |
| 3:1 to 5:1 | Healthy — the conventional target zone |
| Above 5:1 | Excellent, but often a signal you are under-investing in growth |
These LTV/CAC interpretation bands are from Optifai’s 2026 study. The segment caveat matters here as much as anywhere: Optifai notes SMB customers typically run 2–3:1 because their lifespans are shorter (roughly two to three years), while enterprise customers, with five-to-seven-year lifespans, can support far higher ratios. A blanket 3:1 target applied to an SMB-heavy book may be unreachable for structural reasons that have nothing to do with execution.
LTV/CAC also carries a well-known trap: LTV is a forecast, and it is the easiest metric on this page to inflate. A generous churn assumption or an optimistic lifespan can produce a flattering ratio that reality never delivers. This is why Optifai and most disciplined operators treat payback period as the more trustworthy sibling — payback uses only realized cash and near-term revenue, with no long-horizon forecast baked in. When LTV/CAC looks great but payback looks poor, believe the payback.
The SaaS magic number: sales-and-marketing productivity
The magic number measures how much new ARR each dollar of sales-and-marketing spend produces, with the spend lagged by one period to reflect that today’s revenue was bought with last quarter’s investment.
Magic number = new ARR added in the period ÷ sales-and-marketing expense in the prior period
The standard interpretation, as documented in the 2026 Aleph and Benchmarkit report: above 1.0 is strong — each S&M dollar returns more than a dollar of new ARR; 0.75 to 1.0 is the acceptable zone, efficient enough to keep investing; below 0.75 is the warning line, where spend is outrunning returns and the sensible move is to fix the motion before adding fuel. The 0.75 floor is the number worth memorizing, and it is the reason “magic number above 0.75” is the operating rule of thumb across the industry.
| Magic number | Interpretation |
|---|---|
| Above 1.0 | Strong — each S&M dollar returns more than $1 of new ARR; scale spend |
| 0.75 to 1.0 | Acceptable — efficient enough to justify continued investment |
| Below 0.75 | Concerning — fix the motion before adding budget |
These magic-number thresholds are the Aleph and Benchmarkit (2026) interpretation. As for where real companies land: the 2026 Aleph and Benchmarkit report (2025 actuals, 132 companies reporting the metric) puts the median magic number at 1.37, up from 0.94 in 2024 — the population’s first crossing of 1.0. The 75th percentile reached 2.14, while the bottom quartile sat at 0.68, still below the floor. Growth rate is the dominant divider: companies growing faster than 50% a year posted a median magic number of 2.40, while companies in the 11–30% growth band frequently fell below 0.75. The fast growers are not just growing more — they are growing more efficiently, which is the entire point the metric is designed to surface.
Because the magic number is the cleanest read on go-to-market productivity, it is the metric to watch when you are deciding whether to press the accelerator. A number comfortably above 1.0 says the motion works and more money will likely produce proportional revenue; a number below 0.75 says the opposite, and spending into it usually just enlarges the inefficiency. Improving it is the same work as improving CAC — better targeting, higher conversion, stronger sales execution — measured from the revenue side rather than the cost side.
Burn multiple: efficiency of the whole company
Where the magic number isolates sales and marketing, the burn multiple judges the efficiency of the entire company. Coined by David Sacks of Craft Ventures in April 2020, it asks how much cash you burn to generate each incremental dollar of ARR.
Burn multiple = net burn ÷ net new ARR
A lower number is better, and Sacks published a rating scale that has become the standard reference. Because it uses net burn rather than sales-and-marketing cost, the burn multiple captures inefficiency anywhere — bloated engineering, heavy G&A, weak margins — not just an expensive go-to-market. It is the metric a board reaches for when asking whether the company as a whole is converting capital into durable revenue.
| Burn multiple | Rating |
|---|---|
| Under 1x | Amazing |
| 1x to 1.5x | Great |
| 1.5x to 2x | Good |
| 2x to 3x | Suspect |
| Over 3x | Bad |
This burn-multiple rating scale is Sacks’ original framework (Craft Ventures, 2020). He also offered stage-based guidance — roughly 3x is tolerable at seed, dropping toward 2x after Series A and tightening from there, and approaching zero or turning negative as a company reaches maturity and self-funds its growth. Note that a variant scale shifted tighter by half a point circulates online and is sometimes misattributed to Sacks; the table above is the original.
For where private companies actually land, the largest recent sample point comes from Lighter Capital, which reported a median burn multiple of 1.12x among the cash-burning (negative free-cash-flow) companies within its 83-company sample of private B2B SaaS startups in the $250K–$22M ARR range over 2024–2025 — squarely in Sacks’ “great” band, and another data point on the efficiency era’s discipline. Benchmarkit’s 2025 report frames it as a target rather than a distribution, suggesting companies aim for a burn multiple below 1.0 once they reach the $25M–$50M ARR range, since capital efficiency should improve as fixed costs get spread across a larger revenue base.
Why benchmarks lie — and how to set your own targets
Every table on this page carries an implicit asterisk: the median is an average of companies that look nothing like each other. A benchmark lies when you apply a population number to a specific situation it does not describe, and the three variables that break the comparison most often are contract size, go-to-market motion, and stage.
ACV changes everything. The First Page Sage segment table shows enterprise payback running two to three times longer than SMB payback, and Benchmarkit’s CAC-ratio data shows acquisition cost per dollar of ARR varying by contract band. A six-figure enterprise deal justifies a long, expensive, human-led sales cycle because the lifetime value is large; a $60-a-month self-serve product cannot survive that motion and does not need it. Comparing the two against one median tells you nothing.
Motion changes the shape of the numbers. Product-led growth front-loads cost into product and support and shows a low paid CAC but often a heavy blended cost of engineering. Sales-led growth concentrates cost in headcount and commissions. Vertical SaaS, per Aleph and Benchmarkit’s 2025 data, runs a longer payback (18 months median) than horizontal SaaS (14 months) because narrower markets cost more to reach. A PLG company and an enterprise sales company can both be healthy while looking opposite on paper.
Stage changes what “good” means. Sacks’ own guidance concedes that a 3x burn multiple is acceptable at seed and alarming at Series C. A 20-month payback that is fine for a growth-stage enterprise player would sink an early-stage SMB company that cannot finance the cash gap. The same number is a pass or a fail depending on where you sit.
So how do you set targets that actually mean something? Start from your own trailing data, not the population median. Segment your CAC, payback, and LTV/CAC by ACV band and by channel — the blended average hides the channel that is quietly unprofitable and the segment that is carrying the whole book. Pick the benchmark cut that matches your motion and stage rather than the headline number: an SMB PLG company should measure itself against SMB PLG marks, and an enterprise sales company against enterprise ones. Then set improvement targets against your own baseline — a payback moving from 22 to 18 months is real progress regardless of where the median sits. Finally, watch the metrics as a system, because they check each other: a great LTV/CAC alongside a poor payback signals an inflated LTV assumption, and a strong magic number alongside a bad burn multiple points to inefficiency outside sales and marketing. This system view is the foundation of revenue excellence — a revenue-efficiency go-to-market approach where every dollar of spend is measured by the revenue it returns rather than the activity it produces. Getting the measurement right is also what makes the underlying data and attribution infrastructure worth building — benchmarks are only as trustworthy as the numbers feeding them.
A closing note on trust: these figures are directional. They are drawn from self-reported survey data and firm-specific samples, they vary by ACV and segment, and they describe distributions, not destinies. Use them to calibrate expectations and to find the parts of your model that are conspicuously off-market. Do not use them as a substitute for measuring your own business, cohort by cohort, channel by channel. The benchmark tells you roughly where the pack is; only your own data tells you whether the next dollar of spend will pay you back.

Frequently asked questions
What are good B2B SaaS CAC and payback benchmarks in 2026?
Good unit economics in 2026 cluster around a CAC payback period under about 18 months (median near 16 months per Aleph and Benchmarkit’s 2025 actuals, with best-in-class under 12), an LTV/CAC ratio of 3:1 or better (median 3.2:1 per Optifai’s 2026 study), a SaaS magic number above 0.75 and ideally above 1.0 (population median 1.37 in 2025 per Aleph and Benchmarkit), and a burn multiple below 2 for venture-stage companies and below 1 as you scale (per David Sacks’ scale). All of these vary meaningfully by contract size, go-to-market motion, and stage, so treat them as directional targets rather than fixed rules.
What is a good CAC payback period for SaaS?
The working thresholds from Aleph and Benchmarkit’s 2026 report are “good” under 18 months and “top-tier” under 12 months, against a 2025 population median of 16 months. But payback varies heavily by segment: First Page Sage’s 2025 benchmarks put a good SMB payback at 4–11 months, middle market at 8–19 months, and enterprise at 11–24 months. An enterprise company at 20 months is healthy; an SMB company at the same figure is not. Annual prepaid billing is the fastest way to shorten payback because the cash arrives up front.
What is a good LTV to CAC ratio?
The widely cited target is 3:1 or better — three dollars of lifetime gross profit for every dollar of acquisition cost. Optifai’s 2026 study of 939 B2B SaaS companies reports a median of 3.2:1, a healthy band of 3–5:1, and excellent efficiency above 5:1. Below 3:1 the return is usually too thin to be durable; much above 5:1 often signals you are under-investing in growth. SMB-heavy businesses commonly run 2–3:1 because customer lifespans are shorter, so segment before you judge.
What is a good SaaS magic number?
Above 1.0 is strong — each dollar of sales-and-marketing spend returns more than a dollar of new ARR; 0.75 to 1.0 is acceptable; below 0.75 is the warning line where you should fix the go-to-market motion before adding budget, per the interpretation in Aleph and Benchmarkit’s 2026 report. The 2025 population median was 1.37 (up from 0.94 in 2024), and companies growing faster than 50% a year posted a median of 2.40. The formula lags spend by one period: new ARR added divided by the prior period’s sales-and-marketing expense.
What is a good burn multiple?
David Sacks’ original 2020 scale rates a burn multiple under 1x as amazing, 1x–1.5x as great, 1.5x–2x as good, 2x–3x as suspect, and over 3x as bad. The multiple is net burn divided by net new ARR. Early-stage companies can tolerate higher multiples (roughly 3x at seed), tightening toward 1x or negative as they mature. For real-world context, Lighter Capital reported a 1.12x median among the cash-burning companies in its 83-company sample of private B2B SaaS startups in 2024–2025, and Benchmarkit suggests targeting below 1.0 once you reach $25M–$50M in ARR.
What is the difference between blended CAC and paid CAC?
Paid CAC counts only media spend divided by customers acquired through paid channels, so it measures channel efficiency cleanly. Blended CAC divides all sales-and-marketing cost by all new customers, including those from organic search, referrals, and word of mouth, which pulls the average down and makes it the more flattering figure. Fully-loaded CAC adds team salaries, commissions, tooling, and overhead, and is the version that drives payback and LTV/CAC. Always state which one you mean — Benchmarkit’s 2025 median new-customer CAC ratio of $2.00 of spend per $1 of new ARR refers to the fully-loaded, new-customer view.
