Business Valuation Calculator

The math behind every M&A conversation, fundraise, and acquisition diligence. Three textbook methods on the same inputs — DCF, revenue multiple, EBITDA multiple — with comparable transactions optional. The spread between methods is the negotiation insight. Source-cited to Damodaran NYU Stern, McKinsey Valuation, SaaS Capital, and Pitchbook PE deal data.

Trailing-12-month revenue. The denominator behind every multiple-based valuation.

Negative or zero EBITDA → the EBITDA-multiple method returns $0. Use revenue or DCF instead for loss-making businesses.

Preset: 8× revenue, 35× EBITDA (2026 medians).

DCF inputs

5 is the standard. 10+ is rare outside of stable utilities.

Compounded across the projection period. Stress-test by halving this.

SaaS: 15-30%. Mature SaaS at scale: 25-40%. E-commerce: 5-15%.

Federal corporate is 21%; effective rates including state run 25-28%.

Mid-cap private: 10-14%. Early-stage VC: 25-40%. Stable public: 7-9%.

Cap at long-run GDP growth (~2-3%). Higher implies eternal market expansion.

Comparable transactions (optional, up to 5)

Add recent comparable acquisitions or financings. The calculator takes the median of (sale price ÷ revenue) across the comps and applies it to your current revenue.

Method comparison

Median method highlighted. The wider the bar spread, the wider the buyer/seller gap.

Recommendations
  • DCF valuation is 37% lower than revenue-multiple — typical for high-growth companies where multiples imply terminal optimism the DCF doesn't fully credit. Buyers will lean on DCF; sellers will lean on multiples. Plan for that gap in negotiation.

What this means

The point of running all three methods isn't to get a single "right" number — it's to see where the methods agree and where they don't. When DCF, revenue multiple, and EBITDA multiple all cluster within 20% of each other, you have high confidence in the median: that's the company's value, and any negotiation will gravitate toward it. When they spread by 50%+ — which is common, not rare — the buyer/seller gap is real. Buyers will demand the lowest method; sellers will hold out for the highest; the negotiated price lands somewhere in the middle. The spread itself is the most useful output of this calculator.

The most common operator failure mode is anchoring on the highest method (usually revenue multiple in growth scenarios) and treating it as "the" valuation. That works in seller-friendly markets and explodes in buyer-friendly ones. The defensible position: present the median as the headline, but always show the range and explain which method drives the high and the low. M&A advisors who skip that framing are doing their clients a disservice.

Worked example — $5M SaaS company at 30% growth

Mid-stage SaaS company, $5M ARR, $1M EBITDA (20% operating margin), growing 30% YoY. 21% effective tax rate, 12% discount rate, 3% terminal growth.

Revenue multiple: at the SaaS-high-growth preset of 8x revenue, $5M × 8 = $40M.

EBITDA multiple: at the preset 35x EBITDA, $1M × 35 = $35M.

DCF: 5-year projection compounding revenue at 30%, 20% operating margin, 79% after-tax. Year-1 cash flow ≈ $1.03M; year-5 ≈ $2.93M; sum of present values across years 1-5 ≈ $7.6M; terminal value ≈ $33.5M present-valued. Total DCF ≈ $41M— coincidentally close to the revenue multiple in this scenario, but that's sensitive to the discount rate. Drop the discount rate to 10% and DCF jumps to $50M+; raise it to 15% and DCF falls to $30M.

The takeaway:across these three methods the range is $35M–$41M, a 17% spread. That's a healthy convergence — high confidence the company is worth ~$38M (the median). Negotiation will focus on whether the SaaS-high-growth preset is the right comparable set (a buyer will argue for SaaS-mature multiples instead) and whether the 30% growth assumption holds (a buyer will haircut it to 20%). Watch how those two levers move every method's output.
