Key takeaways
- The median B2B SaaS company recovered its customer acquisition cost in 16 months in 2025, down from 18 months a year earlier.
- The fastest quarter of companies paid back CAC in 10 months, while the bottom quartile took 24 months or more.
- Companies growing more than 50% a year had the shortest median payback, at 10 months, and those growing 21 to 30% the longest, at 22 months.
- Contracts under $5K a year paid back in a median of 11 months, against 22 months for $50K to $100K enterprise contracts.
Customer Acquisition Cost (CAC) and CAC Payback Period are two critical metrics for growth companies. They determine how efficiently a business can scale and how much capital is required to sustain that growth. Optimizing these metrics can improve cash flow, increase profitability, and attract investors.
In this article, we provide benchmarks so you can understand performance expectations.
This article gives the latest 2026 CAC payback benchmarks first, then the earlier figures by company size and customer size, each labeled with its year. For the definition, the formula and a calculator, see our CAC payback period guide.
SaaS CAC payback benchmarks 2026
In 2026 the median B2B SaaS company earns back its customer acquisition cost in 16 months, down from 18 months a year earlier. That 11% improvement is tied for the largest single-year improvement in the four years the study has tracked.
| Measure | CAC payback, 2025 actuals | A year earlier |
|---|---|---|
| Median | 16 months | 18 months |
| 25th percentile (fastest quarter) | 10 months | 12 months |
| Bottom quartile | 24 months or more | |
| Slowest company in the sample | 48 months |
CAC payback by growth rate
| Annual growth | Median CAC payback |
|---|---|
| Over 50% | 10 months |
| 21–30% | 22 months |
| 11–20% | 18 months |
| Under 10% | 14 months |
The fastest growers recover their acquisition cost fastest. The slowest growers also recover quickly, because they spend little on acquisition. Companies growing 21–30% take longest: they spend like fast growers without yet converting as efficiently.
CAC payback by customer size
| Annual contract value (ACV) | Median CAC payback |
|---|---|
| Under $5K | 11 months |
| $50K–$100K (enterprise) | 22 months (25th percentile: 15 months) |
Horizontal SaaS companies pay back in a median of 14 months, against 18 months for vertical SaaS.

What is Customer Acquisition Cost (CAC)?
Customer Acquisition Cost, abbreviated CAC or CCA (for Cost of Customer Acquisition), measures the average cost of acquiring a new customer. It includes expenses such as:
- Marketing and advertising
- Business development
- Salaries for sales and marketing teams
- Sales commissions and incentive programs
- Any other costs directly related to customer acquisition
As an example, if your total acquisition costs for a period are $20,000, and you acquire 20 new customers, your CAC is $1,000 per customer.

What is CAC Payback Period?
The CAC Payback Period refers to the time (in months) it takes for a company to recover its CAC through the revenue generated by that customer.A shorter CAC Payback Period means your business recoups its investment faster, reducing cash burn and improving financial sustainability.
To calculate CAC Payback, simply divide CAC per month by the average Gross Margin per customer per month, as shown below. The result will be the number of months required to recoup acquisition costs.
As an example, if CAC or acquisition costs is $1,000, the MRR per customer is $150, and the gross margin is 70%, the CAC payback period would be approximately 9.5 months:
= 1000 / (150 * .7) = 9.5 months

Why is CAC Payback important?
Investors, CEOs, and CFOs closely monitor CAC Payback because it directly impacts business valuation (see SaaS multiples) and financial strategy.
The Venture Capital firm – OpenView Advisors – lists it in the top three most important metrics for SaaS companies, alongside Gross Dollar Retention and Net Dollar Retention. And at ScaleXP, we have certainly seen interest in this metric surge over the last 18 months.
CAC payback by company size (ARR): 2023 data
In assessing your business’ performance vs benchmarks, it is important to consider two factors:
- The size of your company measured by your ARR or annual revenue, and
- Your target customers. Are you selling to large corporates or SMEs?
The graph below shows CAC Payback Period in months for SaaS companies. The horizontal axis indicates company size, starting with companies that have less than $1M ARR and ending with those of $50M ARR.
The green line indicates top quartile performance while the light blue is bottom quartile. It is worth noting that payback periods are shortest for the smallest companies, indicating that these companies are most efficient.

What is the impact of your target customer size?
Both the sector and the size of your target customers will impact your CAC Payback.
- Industries with higher average revenue per customer, such as enterprise fintech tend to have longer payback periods (18–23 months: the “good” and “average” enterprise figures in First Page Sage, SaaS CAC Payback Benchmarks: 2025 Report, published 20 June 2024). This reflects their longer and more complex sales cycles.
- Sectors with shorter sales cycles and acquisition costs, such as edtech, achieve faster payback periods, making them more cash-efficient in the short term.
- The table below shows both average and good performance by size of your customers as well as your SaaS sector.

How can you optimize your CAC Payback?
Here are some key ways to have a material impact on your CAC Payback:
- Monitor your CAC Payback monthly. Tracking performance is critical to improvement.
- Improve your Gross Margin. Companies with the best CAC Payback period have higher Gross Margins. Review your Cost of Sales or Direct Costs to determine if you can trim costs. Hosting costs, which is typically the largest component of Cost of Sales, can be drive lower by looking for start-up or scaleup offers. AWS has generous incentives for start-ups and Google has launched some offers as well.
- Improving Sales Conversions.Train sales teams, refine messaging, and shorten sales cycles.
- Hone your marketing spend. Focus on efficient growth, rather than growth at any costs. Optimize paid campaigns and focus on high-converting channels.

Frequently asked questions
What is a good CAC payback period for a SaaS company?
A good CAC payback period is one that compares well with companies of a similar ARR and a similar target customer, because both shape the benchmark. The OpenView 2023 SaaS Benchmarks Report shows payback periods are shortest for smaller companies, while enterprise-focused businesses carry longer paybacks. ScaleXP calculates CAC payback automatically from Xero or QuickBooks and the CRM, so finance teams track their own figure monthly against the right peer group. Leaders spot efficiency gains early and show investors disciplined, cash-efficient growth.
Can ScaleXP calculate CAC payback automatically from Xero and HubSpot?
Yes, ScaleXP calculates CAC payback automatically by combining sales and marketing costs from Xero or QuickBooks Online with new customer data from HubSpot, Salesforce or Pipedrive. ScaleXP works out customer acquisition cost, new MRR and gross margin, then calculates how many months it takes to earn back the investment in each new customer. The metric updates as data syncs, with no formulas to maintain. Finance teams get a reliable CAC payback figure every month and spend their time improving it rather than calculating it.
How does ScaleXP keep customer acquisition cost consistent with the P&L?
ScaleXP keeps customer acquisition cost consistent with the P&L by taking sales and marketing spend, including salaries, directly from the accounting ledger in Xero or QuickBooks Online. ScaleXP then divides that spend by new customers from the CRM, so CAC reconciles to the same costs the board sees in the management accounts. There is no separate marketing spreadsheet drifting away from the financial statements. The result is a CAC and CAC payback figure that investors trust and that finance can defend line by line.
How do SaaS finance teams use ScaleXP to shorten CAC payback?
SaaS finance teams use ScaleXP to shorten CAC payback by monitoring it monthly and seeing exactly which levers move it. ScaleXP tracks customer acquisition cost, gross margin and new MRR together, and breaks them down by segment, product line or tracking category from Xero or QuickBooks. Teams quickly see where hosting costs squeeze gross margin or where sales spend is not converting. Matan, Director of Finance, notes: “The prebuilt KPIs are really valuable and save me a lot of time.” Leaders act sooner and grow more efficiently.
What is the median CAC payback period in 2026?
The median B2B SaaS company recovers its customer acquisition cost in 16 months, according to the 2026 Aleph × Benchmarkit benchmarks (full-year 2025 actuals, published 1 June 2026). That is down from 18 months a year earlier. The fastest quarter of companies pay back in 10 months or less, while the bottom quartile takes 24 months or more. ScaleXP calculates CAC payback automatically every month from your accounting and CRM data, so you can see where you sit against these figures.
