“A good CAC payback period is 12 months” is the most repeated number in SaaS finance, and it is not a benchmark. It is a target, borrowed from one segment and quoted without the cohort that would tell you whether it applies to you.
A CAC payback period is the number of months of gross profit a new customer takes to earn back what it cost to win them. The figure only means something next to three facts: whose companies were measured, in which year, and at what deal size. Leave any of them out and the same business can look top-quartile or bottom-quartile.
This piece sets out the CAC payback period benchmarks that do name their cohort, the five ways the numbers get quoted wrong, and how to pick the comparison that fits a B2B SaaS or fintech company. It is written for founders who report the metric to a board, and for fintech founders and CMOs who have been handed a SaaS benchmark and told it applies to them.
The short version
- The most current named benchmark, the 2026 Aleph × Benchmarkit report, puts median B2B SaaS CAC payback at 16 months. That is 198 companies, full-year 2025 data.
- Its top quartile pays back in 6 months or fewer and its bottom quartile takes 24 months or more. At $50K–$100K ACV the median is 22 months.
- An older survey of more than 100 private SaaS companies put the 2022 median near 23 months. Different cohort, different year, different answer.
- “Under 12 months” comes from investor targets for SMB-focused companies. It is not a measured median.
- We found no named, sample-sized CAC payback benchmark for fintech. We say so rather than invent one.

What a CAC payback period measures
Customer acquisition cost is what you spent on sales and marketing to win new customers. The CAC payback period turns that into time: how many months of gross profit from those customers it takes to recover the spend. Investors like it because it answers a cash question. Until payback, every new customer is a loan the company made to itself.
The formula most benchmark reports use, as Aleph publishes it for the 2026 Aleph × Benchmarkit data:
CAC payback (months) = sales and marketing expense (prior period) ÷ (new ARR added × gross margin %) × 12
Two details in that formula change the answer materially, and Aleph’s page names both. Use gross-margin-adjusted revenue, not raw ARR, or low-margin businesses look better than they are. And lag the sales and marketing spend, because the spend that closed this quarter’s deals mostly went out in earlier quarters.

The CAC payback formula, run three ways on one company
Here is why the inputs matter more than the arithmetic. The figures below are illustrative, not a client’s: one quarter at a company growing its spend, calculated three common ways.
| Inputs and method | Calculation | CAC payback |
|---|---|---|
| Prior-quarter sales and marketing expense $600,000; new-customer ARR $800,000; gross margin 75%. Gross-margin-adjusted and lagged | $600,000 ÷ ($800,000 × 0.75) × 12 | 12 months |
| Same, but no gross margin adjustment | $600,000 ÷ $800,000 × 12 | 9 months |
| Same, but current-quarter spend ($450,000) with no lag | $450,000 ÷ ($800,000 × 0.75) × 12 | 9 months |
| Same as the first row, but expansion ARR ($200,000) added to new ARR | $600,000 ÷ ($1,000,000 × 0.75) × 12 | About 9.6 months |
Same company, same quarter: a 12-month payback or a 9-month one, depending on method. Before you compare your number with anyone’s benchmark, check that you calculated it the way they did. To run your own numbers this way, use the customer acquisition cost calculator, which works out blended and paid CAC, CAC payback on gross margin and LTV:CAC.
CAC payback benchmarks: three sources, three cohorts
These are the CAC payback benchmarks we could trace to a named source, with the cohort and data year each one describes. They disagree, and that is the point. Each is a true statement about a different group of companies.
| Source | Cohort | Data year | What it says |
|---|---|---|---|
| 2026 Aleph × Benchmarkit SaaS & AI Performance Benchmarks (published 1 June 2026) | 342 B2B SaaS and AI-native software companies; 198 reported CAC payback | Full-year 2025 | Median 16 months (18 in 2024). Top quartile ≤6, bottom quartile ≥24, worst in the sample 48 |
| KeyBanc Capital Markets and Sapphire Ventures, 14th Private SaaS Company Survey (released December 2023) | “More than 100” private SaaS companies, median 2022 ARR $25.5M, sectors including fintech | 2022 | Median CAC payback of about 23 months |
| Bessemer Venture Partners, Scaling to $100 Million (published 21 September 2021) | Bessemer’s cloud portfolio. No sample size is stated for the payback figures | Portfolio data; period not stated (published 2021) | Average of 15 months at $1–10M ARR. Targets: under 12 months SMB, under 18 mid-market, under 24 enterprise |
Read that table as three answers to three different questions. Aleph × Benchmarkit measured a large, recent, mixed cohort. KeyBanc and Sapphire measured private companies with a median ARR of $25.5M, on 2022 data. Bessemer published an average from its own portfolio, plus targets that describe what it wants to see, not what it measured.

The same Aleph data shows how much the cohort moves the number. Horizontal B2B SaaS paid back in 14 months at the median, vertical SaaS in 18. Companies growing faster than 50% paid back in 10 months; companies growing 21–30% took 22. None of those is “the” benchmark. Each is the right one for somebody.
Five ways CAC payback numbers get quoted wrong
1. The cohort is missing
“The median is 16 months” is only half a fact. The full fact is 16 months across 198 companies that reported the metric, on full-year 2025 actuals, in a report published in 2026. The report year and the data year are one year apart, and Aleph’s page flags that itself. So does the sample: 342 companies took part, but only 198 of them supplied a CAC payback figure.
Even the source rewards a close read. The same page gives the top quartile as 6 months or fewer and, a few lines later, says the 25th percentile dropped from 12 to 10 months. We could not reconcile those two statements from the page, so we quote the quartile boundaries it states in its benchmark summary and leave the 10-month figure out.
2. A target is quoted as a benchmark
The “12 months is good” rule has a traceable home. Bessemer’s 2021 report tells SMB-focused cloud companies to target CAC payback under 12 months, mid-market under 18 and enterprise under 24. Those are an investor’s targets by segment. Strip off the segment and the word “target,” and you get the number every pitch deck repeats.
Benchmarkit’s own 2025 findings page makes the same point from the other side: “Common wisdom often says ~12 months CAC Payback Period is good,” it notes, before adding that the metric is highly correlated to deal size.

3. It is a different payback altogether
Not every “payback” is CAC payback. The 2025 KeyBanc and Sapphire survey page reports that account executive payback periods are expected to shorten to 18 months by 2026. That measures how long a salesperson takes to cover their own cost. It is a hiring metric, and quoting it as a customer acquisition figure mixes up two different questions.

4. The formula does not match
The table above showed the same company at 9 months and at 12. Skipping the gross margin adjustment, skipping the lag, or folding expansion ARR into new ARR each flatters the number. A benchmark calculated one way tells you nothing about a figure calculated another. If a vendor or an agency quotes you a payback, ask which formula produced it.
5. The wrong deal size, or an average read as a median
Aleph’s data puts the sub-$5K ACV median at 11 months and the $50K–$100K median at 22. An enterprise seller measured against the all-company 16-month median looks worse than it is, and a self-serve product looks better. Bessemer’s 15 months is also an average, not a median: a few slow payers pull an average up in a way they do not pull a median.
Choosing the right SaaS payback period benchmark
The useful SaaS payback period benchmark is the one whose cohort looks like your company. Aleph’s published cuts give three ways to find it.
| Cut (Aleph × Benchmarkit, 2025 data) | Segment | Median CAC payback |
|---|---|---|
| Deal size | Sub-$5K ACV | 11 months |
| Deal size | $50K–$100K ACV (25th percentile: 15 months) | 22 months |
| Growth rate | More than 50% growth | 10 months |
| Growth rate | 21–30% growth | 22 months |
| Growth rate | 11–20% growth | 18 months |
| Growth rate | Under 10% growth | 14 months |
| Market | Horizontal B2B SaaS | 14 months |
| Market | Vertical SaaS | 18 months |
| All companies | 198 reporting | 16 months |
Three rules make the comparison fair:
- Match the deal size first. Annual contract value is the attribute Benchmarkit says the metric is most correlated with, and the spread in the table above bears that out.
- Match the formula. Gross-margin-adjusted, lagged, new-customer ARR only, unless the benchmark says otherwise.
- Watch the trend, not one quarter. A rolling figure tells you whether sales efficiency is improving. A single quarter mostly tells you when the big deals closed.
If your CAC payback period sits inside the band for your segment, the headline median is irrelevant. If it sits outside, the next step is to find which input is off: gross margin, the timing of spend, or a customer acquisition cost too high for the deal size.
Fintech CAC payback: the benchmark we could not find
We looked for a named, sample-sized CAC payback benchmark for fintech and did not find one as of 25 September 2026. The KeyBanc and Sapphire survey included fintech among its sectors, but its press release does not break payback out by sector. Any single “fintech CAC payback” figure you see quoted should come with a named study and a sample. If it does not, treat it as an opinion.
The nearest structural cut is Aleph’s vertical and horizontal split. A fintech selling compliance software into banks behaves more like vertical SaaS (18 months at the median). A payments API sold to any developer behaves more like horizontal SaaS (14 months). That is a starting comparison, not a fintech benchmark.
What SaaS benchmarks do not price in is the regulatory cost of acquisition. In Google Ads, financial services advertisers must complete verification separately for each region they target on Google’s list of 42 regions. The United Kingdom has been enforced since 6 September 2021. The United States is not on the list, and neither is any African country. The time and legal review that verification takes are real acquisition cost. We explain the process in our guide to Google Ads financial services verification.

How we report CAC payback period
CAC payback period is the first metric on the list of what we report, published on how we work, alongside marketing-sourced pipeline and SQL conversion rate by source. It is measured over a window that matches your sales cycle. We do not report any 30-day performance window, for the reasons set out in ROAS vs CAC: why ROAS misleads in B2B SaaS.
We quote the benchmark the same way this piece does: median 16 months, about 22 at $50K–$100K ACV, with the top quarter of the 198 companies at six months or less. A promise of sub-12-month payback is a promise of better-than-median performance, and we do not make it before we have seen your numbers.
If you want your own CAC payback calculated from your books and set against the right segment, that is part of the Acquisition Audit: two weeks, a fixed $2,500, and a written diagnosis of your search and paid acquisition that you can act on with us or without us.
FAQ: CAC payback period
What is a good CAC payback period?
It depends on your deal size and cohort. In the 2026 Aleph × Benchmarkit data (198 companies, 2025 actuals), the median is 16 months, the top quartile 6 months or fewer and the bottom quartile 24 or more. Compare yourself with your ACV band, not the headline.
How do you calculate CAC payback?
Divide prior-period sales and marketing expense by new ARR multiplied by gross margin, then multiply by 12. Adjust for gross margin and lag the spend, or the figure will usually come out too low.
Is 12 months a good CAC payback period?
It is better than the 2025 median of 16 months. But “under 12” started as an investor target for SMB-focused companies, not a measured benchmark. For a $50K–$100K ACV seller, where the median is 22 months, 12 would be exceptional.
What is the average CAC payback period for SaaS?
Most reports publish a median, not an average. Aleph × Benchmarkit’s median is 16 months for 2025. A KeyBanc and Sapphire survey of more than 100 private SaaS companies put the 2022 median near 23 months. Always quote the cohort and year with the number.
Is there a CAC payback benchmark for fintech?
We could not find a named fintech benchmark with a stated sample size. The closest published cut is vertical SaaS (18 months) against horizontal (14 months), from the 2026 Aleph × Benchmarkit data.
CAC payback period benchmarks: what to do next
A benchmark is only as useful as the match between its cohort and your company. Before the next board deck:
- Recalculate your CAC payback period with gross margin adjusted and the spend lagged.
- Separate new-customer ARR from expansion ARR.
- Pick the benchmark row for your ACV band and growth rate, and write the source, sample and data year next to it.
- If you sell into regulated financial services, add the cost of verification and compliance review to CAC rather than leaving it in legal’s budget.
Quote the number with its cohort, and the CAC payback period becomes the most honest efficiency figure you report.
