SaaS Valuation Calculator
See what your growth, retention and margin are worth against the private-market median, and what one point of NRR is worth to you.
What this calculates
This starts from the median multiple private B2B SaaS companies were valued at in 2026 and adjusts it for how far your growth, net revenue retention and Rule of 40 sit from the medians of the same survey. It is a directional range, not a valuation opinion, and it is most useful for deciding which lever to pull before you raise.
At typical inputs for a B2B SaaS company at $6.4M ARR with 58% year-on-year growth, 112% net revenue retention and a Rule of 40 score of 43, this calculator estimates an enterprise value of $50.5M, a 7.9× revenue multiple.

Healthy
You are priced above the private-market median, and growth is doing most of that work. The constraint on this number is durability rather than level. A buyer will test whether this growth rate holds for another four quarters before paying for it, and retention is the evidence they will look at first.

How is this calculated?
The starting point is the multiple a median private B2B SaaS company was valued at in 2026. Three adjustments move it: how far your growth sits from the survey median, how far your net revenue retention sits from its median, and where your Rule of 40 score lands against 40. Gross margin then scales the result against a 78% reference, because a dollar of low-margin revenue is worth less than a dollar of software revenue.
Formula
Rule of 40 = growth + EBITDA margin M = (5.0 + (growth − 22) × 0.06 + (NRR − 103) × 0.05 + R40 premium) × (GM ÷ 78) R40 premium = (Rule of 40 − 40) × 0.03, held between −1.5 and +1.5 Enterprise value = ARR × clamp(M, 2.0, 12.0) At the median profile (22% growth, 103% NRR, 78% margin, Rule of 40 at 40) the model returns exactly 5.0×.
- The 5.0× starting point sits between the two figures SaaS Capital publishes for private B2B SaaS: 4.8× for bootstrapped companies and 5.3× for equity-backed ones.
- The median profile it is anchored to, 22% growth and 103% net revenue retention, comes from the same survey of private B2B SaaS companies at $3M to $20M ARR.
- The three slopes, 0.06 of a turn per point of growth, 0.05 per point of NRR and 0.03 per point of Rule of 40, are calibration rather than measurement. They are set so the model returns the published median at the median profile and lands inside the 6× to 8× band reported for companies above 30% growth and 110% retention. Change them if you have better numbers.
- The range is the same model run at ten points of growth either side of your input, which is roughly what one large deal moves a trailing growth rate.
- ARR means subscription revenue that renews, with one-time fees and services excluded. The ARR Calculator works that figure out from MRR if you do not have it to hand.
- Nothing here adjusts for debt, cash, customer concentration, contract length or founder dependency, and the multiple is held between 2.0× and 12.0×.
When this number misleads
If more than 20% of ARR sits with one customer, or your growth came from a single large deal that will not repeat, this multiple is optimistic by a wide margin. Concentration is the first thing a buyer diligences and the first thing that moves the number down. This tool cannot see it, because nothing you enter describes how your revenue is distributed.
Questions founders ask about this
Is this what an investor would actually pay?
No. It is the starting point a banker would anchor on before diligence. Expect the real number to land below this range if there is concentration or churn hiding in the cohort data, and above it if you have a strategic acquirer with a reason to move fast.
Where does the 5.0× starting point come from?
From SaaS Capital’s 2026 analysis of private B2B SaaS valuations, which puts the predicted multiple at 4.8× for bootstrapped companies and 5.3× for equity-backed ones. The model uses 5.0× as the midpoint and adjusts from there. Public SaaS trades higher, around 7×, and private companies carry a persistent discount to that.
Why does NRR move the number so much?
Because it is the only input that compounds without spend. At 112% retention your existing base grows itself. At 95% you refill a leaking bucket before you grow at all, and every dollar of new sales has a shorter useful life. Buyers price that difference heavily.
