SaaS Valuation Calculator

What's your SaaS worth? Enter your ARR, growth rate and margin, and this estimates a valuation range using revenue multiples and the Rule of 40 — the back-of-envelope maths investors and acquirers actually start from.

Free vs paid — when to upgrade

What this free tool is great for: a quick, one-off job with no signup — it runs entirely in your browser, so nothing leaves your device and there's nothing to manage.

Its honest limit: it's a one-off calculation in your browser — it doesn't save your scenarios, update as your real numbers change, or connect to your live accounts, so you re-enter the figures every time and can't watch how they move.

Where Flippa does more: A number on a screen is one thing; a real offer is another. When you're ready to sell, a marketplace like Flippa connects you with vetted buyers for online businesses and SaaS.

How software businesses actually get valued

Most SaaS companies aren't valued on profit the way a traditional business is — they're valued on a multiple of revenue, usually annual recurring revenue. The logic is that recurring, predictable subscription income is worth paying a premium for, so buyers price it as a multiple of that revenue base. The entire game, then, is what multiple applies. The same million in ARR might be worth two times that in one company and twelve times in another, and understanding what drives the multiple up or down is the difference between a realistic expectation and a fantasy. This calculator gives you a starting range; the rest is understanding why the range is so wide.

What drives the multiple

Growth is the dominant lever. A SaaS business growing fast commands a far higher multiple than a flat one, because buyers are paying for the future revenue that growth implies, not just today's. After growth come retention and margins. The Rule of 40 — your growth rate plus your profit margin should clear 40 — is the quick test investors apply to see whether you're balancing the two sensibly. High retention, healthy gross margins and efficient customer acquisition all push the multiple up; heavy churn, thin margins and expensive growth push it down. Two companies with identical revenue can sit at opposite ends of the range purely on the strength of these underlying metrics.

Revenue multiples versus earnings multiples

Which yardstick applies depends largely on size and stage. Smaller software businesses, especially bootstrapped or profitable ones, are often valued on a multiple of their earnings — seller's discretionary earnings or EBITDA — because the buyer is purchasing a profit stream. Larger, faster-growing, venture-backed companies are valued on revenue multiples, because they're often reinvesting everything into growth and have little profit to multiply. Knowing which frame your business falls into matters: a profitable, slow-growing tool valued on an earnings multiple lives in a very different numeric world than a high-burn, high-growth startup valued on ARR. Applying the wrong frame produces a number that no buyer will recognise.

The quality of your revenue, not just the amount

Buyers look past the headline revenue to how good that revenue is. Recurring subscription revenue is worth more than one-off project income. Low churn is worth more than high churn, because it means the revenue will still be there next year. Revenue spread across many customers is safer — and worth more — than the same revenue concentrated in two clients who could leave and halve the business overnight. Longer contracts, annual prepayment and expanding accounts all raise quality. So a company can grow its valuation not by adding revenue at all, but by making its existing revenue stickier, more diversified and more predictable. Revenue quality is often where the real value work happens.

Why two identical-revenue companies get very different offers

It genuinely happens that two businesses with the same ARR receive offers that differ severalfold, and every reason traces back to the factors above. One is growing quickly with delighted, sticky customers and clean books; the other is flat, leaking customers, dependent on a couple of big accounts and messy under the hood. The revenue line looks the same; the businesses are worth wildly different amounts because a buyer is purchasing the future, not the present. This is why chasing revenue growth while ignoring retention, concentration and financial hygiene can leave you with a business that's large but hard to sell for a good multiple.

A valuation is not a price

It's crucial to separate two ideas. A valuation is an estimate of what a business might be worth; a price is what an actual buyer actually pays. A calculator, a formula or an advisor can produce a valuation, but only a real transaction produces a price — and the two can differ meaningfully. The price is set by what a motivated buyer will pay in the market conditions of the moment, informed by comparable deals and their own strategic needs. Treat any valuation estimate, including the one here, as a way to set expectations and prepare, not as a number you can hold a buyer to. The market has the final say.

When to get a real valuation

A quick estimate is fine for orientation, but certain moments call for something more rigorous. Raising a priced round, entertaining an acquisition offer, bringing in or buying out a partner, or planning a sale all warrant a proper valuation grounded in your actual financials and real comparable transactions. At those moments the difference between a rough estimate and a defensible number is often a large amount of money and your negotiating credibility. Use a calculator to know roughly where you stand and to see how improving your metrics would move the range; bring in real data and, where the stakes justify it, real expertise when an actual deal is on the table.

Market conditions move every multiple

The multiples the whole market pays for SaaS rise and fall with the wider economy, interest rates and investor appetite. In exuberant times, multiples inflate and even mediocre businesses fetch rich prices; in cautious times, the same business at the same metrics is worth markedly less through no fault of its own. This is why a valuation is a moment-in-time estimate, not a permanent property of your company, and why timing can matter as much as fundamentals. You can't control the market, but you can control your metrics and your readiness — so that when conditions are favourable, you're in a position to act rather than scrambling to clean up.

From an estimate to an actual sale — where Flippa does more

This calculator turns your revenue and growth into a sensible starting range, which is genuinely useful for setting expectations and spotting which metrics to improve. But an estimate only becomes a real number when a real buyer makes an offer — and finding those buyers, seeing what comparable businesses actually sold for, and running an actual transaction is a different job. That's where a marketplace like Flippa does more: it's where online businesses and SaaS companies are actually bought and sold, with comparable-sale data and a pool of real buyers. Use this tool to understand and improve your valuation; use a marketplace when you want to discover what someone will genuinely pay for it.
