Your R&D as a share of ARR
25%
Formula: R&D spend / ARR = $2,500,000 / $10,000,000.
Against the private SaaS median
In line with the median: +3 points versus 22%
At your ARR, a 22% ratio would be $2,200,000 a year. You spend $2,500,000, a difference of $300,000. "In line" means within 3 points of the median: that tolerance is our rule of thumb, not a sourced band.
Context for your growth and profit band
- Your ratio is within a few points of the private-SaaS median, so a gap to the median is unlikely to be the board question. Expect questions about what the spend delivers instead. rule of thumb
- In a middle growth band, compare against the median first, then against your own plan. We have no sourced band for this growth range, so treat the median as a reference, not a target. rule of thumb
- You are not yet profitable, so the budget will be read against your runway and plan. Show the ratio you are targeting and the date you expect to reach it. rule of thumb
3 questions your CFO will ask
- R&D is 25% of ARR, near the 22% private median. What does the money deliver this year?
- How much of the spend is new product versus maintenance, support and keeping the lights on?
- If we had to cut or add 10% to this budget, what would change in the roadmap, and when would we see it?
How this is calculated
These are the exact formulas the tool uses. Nothing else is hidden.
- R&D spend (headcount entry only)
spend = engineers x fully loaded annual cost per engineer
- R&D as a share of ARR
R&D % = annual R&D spend / ARR x 100
- Gap to the median
gap (points) = your R&D % - 22 spend at the median ratio = ARR x 22% difference = your spend - spend at the median ratio
- Position label (our rule of thumb)
below gap < -3 points in line gap from -3 to +3 points above gap > +3 points
The only sourced reference points are the 22% median and the 24% figure for $3M to $5M ARR, both from the SaaS Capital 2026 survey. The growth and profit inputs change the notes only; they do not change any number, because we found no sourced figures for those bands. Every note is labelled "sourced" or "rule of thumb".
What counts as R&D
Decide the definition before you compare. A common choice is engineering, product management and design payroll, plus contractors, development tooling and non-production cloud costs. Support, customer success and hosting cost of goods usually sit elsewhere. Capitalised software and stock-based compensation change the number too. SaaS Capital does not publish its definition in the article, so a gap to its median can come partly from definition. Use one definition every period and say which you used when you quote the ratio.
Benchmarks and their caveats
The 22% median comes from SaaS Capital's 15th annual survey of private B2B SaaS companies (more than 1,000 respondents, completed March 2026), and was unchanged on the year before. The survey asks for a percentage of revenue but reports the result as a percentage of ARR, and the article does not reconcile the two. It is a self-reported survey of private companies, so it is not a public-company comparison and it is not audited. The article also reports that equity-backed companies spend 56% more on R&D than bootstrapped ones, as a relative difference with no absolute figures in the text, and that higher-growth bootstrapped companies spend more than lower-growth ones, shown only in a chart. Public-company ratios and other vendors' surveys use different samples and definitions, so we do not mix them in here.
Early-stage outliers
Below roughly $3M of ARR, the ratio is dominated by a handful of salaries. A four-person team on a $1M ARR business is above 50% of ARR without being wasteful. For a typical company at $3M to $5M of ARR, SaaS Capital reports 24% of ARR. Before that, judge the budget by runway, the milestones it funds and what you would cut first. These are our rules of thumb.
How to present the engineering budget
Lead with outcomes, then the ratio. Say what the budget buys this year, split it between new product, reliability and maintenance, and show what changes at plus or minus 10%. Quote the benchmark as context, with its source and definition, and never as the justification on its own. The structure is covered in board-ready CTO communication, and the CTO board update template has a spend-versus-budget block. If the budget depends on how the team is shaped, see scaling your engineering org and the engineering org chart tool.
Frequently asked questions
What percentage of revenue should a SaaS company spend on engineering?
There is no single right number. SaaS Capital's 2026 survey of more than 1,000 private B2B SaaS companies found a median R&D spend of 22% of ARR, unchanged from the previous year, and 24% for a typical company with $3M to $5M of ARR. Treat the median as a reference point to explain your ratio against, not a target to hit.
Is the benchmark a percentage of ARR or of revenue?
SaaS Capital reports its results as a percentage of ARR, although the survey question asks about a percentage of revenue and the article does not explain the difference. For a company that is almost all subscription revenue the two are close. If you have material services or usage revenue, calculate both and say which you used.
Does R&D spend equal engineering spend?
Not necessarily. R&D usually includes product management and design as well as engineering, and may include or exclude contractors, tooling and cloud costs for development. SaaS Capital does not define R&D in the text of its article, so use one consistent definition and state it whenever you quote your ratio.
Should an early-stage startup compare itself with the median?
Cautiously. When revenue is small, a few salaries make the ratio very high, and it says more about stage than about efficiency. Use the ratio together with runway and what the team is committed to deliver. That guidance is our rule of thumb, not a sourced finding.
