💹 EV to Sales Calculator

When a company has no earnings, earnings multiples are useless, but revenue multiples still work. EV to sales divides enterprise value by revenue, pricing each dollar of sales. Growth investors live by it for SaaS, biotech, and any business reinvesting every cent of profit into expansion.

How to Use This Calculator

The Formula

Use enterprise value rather than market cap so debt does not distort the comparison, and forward revenue for growth companies where trailing sales understate the business. Unlike earnings multiples, this one never goes negative, which is exactly its appeal and its danger.

Worked Example

A cloud company carries an enterprise value of $575 million on $230 million of trailing revenue: EV/Sales = 2.50x. Each dollar of revenue is priced at $2.50 of enterprise value. Against SaaS peers trading at 6 to 10x, it looks cheap, but the peers grow 40 percent with 80 percent gross margins while this one grows 12 percent at 50 percent margins. The multiple only means something against comparable economics.

Tips for Using Revenue Multiples

Always pair EV/Sales with growth and margin context; a low multiple on a no-growth, low-margin business is not a bargain. Use forward revenue for companies doubling yearly, since trailing sales price the past. Segment conglomerates before applying peer multiples, because blended revenue mixes businesses the market prices differently. And sanity-check against EV/EBITDA wherever earnings exist; persistent divergence between the two flags margin stories the revenue multiple hides.

Common Mistakes

Using market cap instead of EV flatters levered companies and punishes cash-rich ones. Comparing a 90-percent-margin software multiple with a 20-percent-margin retailer multiple is category error, not insight. Annualizing one strong quarter's revenue into "run-rate sales" bakes seasonality into valuation. The deepest mistake is treating revenue as value: sales without margins are vanity, and the multiple must eventually be justified by profits.

Sum-of-the-parts analysis rescues conglomerates from blended multiples. Value each division at its own peer-group EV/sales, add them up, and compare with the consolidated multiple the market applies. Conglomerate discounts often evaporate under this lens, revealing breakup value 20 to 30 percent above the trading price. Activist investors run exactly this math before launching campaigns.

When Earnings Multiples Fail

Early-stage companies deliberately run losses to buy growth, making P/E negative and EV/EBITDA meaningless. Revenue multiples fill the gap, but they demand extra discipline: project when margins inflect positive and what steady-state margins look like, then check whether the current multiple survives that math. A 10x sales multiple needs roughly 30 percent long-run margins at a 30x earnings multiple just to break even on valuation logic.

EV/Sales in M and A

Acquirers love revenue multiples for growth targets because they sidestep the target's depressed or manipulated earnings. A strategic buyer paying 4x sales for a SaaS company is really buying the customer base and cross-sell potential, betting that its own margins will eventually apply to those revenues. The multiple prices the revenue; the strategic rationale justifies it.

Sellers should present revenue quality alongside the multiple: recurring versus one-time, contracted versus transactional, growing versus flat. Two companies at 3x sales deserve different outcomes when one has 95 percent net revenue retention and the other churns 30 percent yearly. Sophisticated buyers adjust the multiple for these; unsophisticated ones learn later.

Earnouts often bridge EV/sales disagreements: part of the price pays on revenue actually delivered post-close. It aligns incentives and shares the forecasting risk. When a buyer insists on 2x and you believe 4x, an earnout to 3x on hitting targets beats a stalemate.

The Rule of 40

SaaS investors condense growth-plus-margin into the Rule of 40: revenue growth rate plus EBITDA margin should exceed 40 percent. A company growing 30 percent at 20 percent margins scores 50, elite; one growing 50 percent at −30 percent margins scores 20, burning. EV/sales multiples track this score closely, which is why the rule predicts valuations better than growth alone.

The rule's wisdom is the tradeoff it blesses: sacrificing margin for growth is fine, and sacrificing growth for margin is fine, but sacrificing both is not a strategy. It gives founders permission to burn cash for growth while keeping a measurable discipline. Below 40, the business must explain itself; above it, the multiple takes care of itself.

Variants use free cash flow margin instead of EBITDA, stricter and better. Whatever the flavor, pair the Rule of 40 with EV/sales: the multiple tells you the price, the rule tells you whether the quality justifies it. A 10x multiple on a Rule-of-60 company is reasonable; on a Rule-of-20 company it is a prayer.
