A valuation ratio that divides a SaaS company's enterprise value by its annual recurring revenue, showing how many times its current recurring revenue a buyer or investor is willing to pay for the business.
ARR multiple = Enterprise value ÷ Annual recurring revenue
A SaaS business doing £150,000 MRR receives an acquisition offer at an £8.1m enterprise value.
ARR = £150,000 × 12 = £1,800,000. ARR multiple = £8,100,000 ÷ £1,800,000 = 4.5x — in line with the 4.5x median EV/Revenue that private SaaS companies sold for across 2015–2026, so a fair market-rate offer for an average-quality business (for an all-recurring business the two bases coincide).
The ARR multiple is the standard shorthand for pricing a SaaS business: enterprise value divided by annual recurring revenue. For a public company, enterprise value is market capitalisation plus debt minus cash; in most private acquisitions it is simply the headline deal price. Investors anchor on ARR because recurring revenue is predictable — a pound of subscription revenue is worth more than a pound of one-off services revenue.
The multiple prices the quality of your ARR, not just its size. Two companies with identical £2m ARR can trade multiples apart. Growth rate is the biggest driver — SaaS Capital publishes its public-company index broken down by growth band for exactly this reason — followed by net revenue retention, gross margin, and Rule of 40. Improving those operating metrics is the only lever a founder controls over their multiple.
The most common mistake is benchmarking against the wrong base. Headline public-market multiples do not apply to a small private business: private deals trade at a discount to listed comps, and a £1m-ARR company will not fetch what a £100m-ARR company does. And an EV/ARR multiple only equals an EV/revenue multiple when all revenue is recurring — if your 'ARR' quietly includes services or one-off fees, the multiple gets re-cut in diligence.
Unlike MRR or churn, the ARR multiple is not a metric you track monthly. It is a market price signal that moves with interest rates and sentiment, and it moves violently: public SaaS multiples peaked at roughly 18–19x in 2021, collapsed through 2022, and sat around 3.4x by March 2026. The market decides the multiple and the timing; you decide the ARR and the metrics that earn a premium on it.
The ARR multiple converts your operating metrics into a price on the whole business. Every point of growth, retention, and margin you add compounds through it — an extra £100k of ARR at a 4.5x multiple is £450k of enterprise value. Knowing the realistic multiple for your stage and growth rate keeps fundraising dilution, exit expectations, and "should I sell?" decisions grounded in market data rather than 2021 headlines.
Across 2015–2026 the median private SaaS company sold for 4.5x EV/Revenue, with top-quartile deals clearing 8.1x (Aventis Advisors deal data). Public SaaS medians swing far more widely — from an 18–19x peak in 2021 to roughly 3.4x by March 2026.
For a private SaaS business, the long-run median sale price is about 4.5x revenue, with top-quartile deals clearing 8.1x (Aventis Advisors, 2015–2026 deal data) — for a pure-subscription business that is effectively the ARR multiple. Fast growth, net revenue retention above 110%, and strong gross margins are what push a company from the median toward the top quartile.
Divide enterprise value by annual recurring revenue. For a public company, enterprise value is market capitalisation plus debt minus cash; for a private acquisition it is usually the headline deal price. A business bought for £9m with £2m ARR sold at a 4.5x ARR multiple.
It means a buyer or investor is paying ten times the company's current annual recurring revenue — a £2m ARR business valued at 10x is worth £20m. A 10x multiple prices in years of future growth, so it is reserved for businesses growing fast with strong retention, well above the long-run private-market median of around 4.5x revenue.
Only when every pound of revenue is recurring. A revenue multiple uses total trailing revenue including services and one-off fees; an ARR multiple uses only the recurring run-rate. Because ARR is usually the smaller base, the same deal produces a higher EV/ARR number than EV/revenue — so always check which base a benchmark uses before comparing.
