How to Value a SaaS Business: A Step-by-Step Method With a Worked Example

Valuing a SaaS business isn't about finding the magic multiple. It's about cleaning up your numbers, choosing the right method for your size, and adjusting honestly for quality. Here's the method, step by step.

By Robert Coorey Updated 7 min read
The short answer

To value a SaaS business, calculate clean ARR (recurring only, excluding one-off fees and sales tax), measure growth, net and gross retention, gross margin and profitability, then choose a method: an ARR multiple for growing companies, a profit multiple for small or mature ones. Start from a current benchmark, adjust for quality and risk, cross-check with a second method, and give a range.

Key takeaways

  • Start with clean ARR: recurring revenue only, excluding setup fees, services and GST or sales tax.
  • Small, founder-run SaaS is usually valued on profit (SDE); growing SaaS on an ARR multiple; mature SaaS on EBITDA or cash flow.
  • In September 2026 the public SaaS median was 4.2x run-rate revenue. Private companies usually trade below that.
  • Adjust for growth, retention, margin, size, concentration and founder dependence. Each can move the multiple meaningfully.
  • Always cross-check with a second method, and present a range, not a single number.

When I wrote The Subscription Playbook, Superhuman was valued at $825 million.

It had engineered product/market fit better than almost anyone, and I told the story of how Rahul Vohra did it. Users loved the product and paid a premium for it.

In July 2025, Grammarly announced it was acquiring Superhuman. Terms weren't disclosed. By then, Superhuman reportedly had about $35 million in annual revenue. Even against that later revenue, its 2021 valuation was about 24 times. (You can read what happened in the Superhuman case study.)

We don't know what Grammarly paid. But the story teaches the first rule of valuing a SaaS business: a valuation is a moment, not a fact. It depends on your numbers, the market at the time and who's buying.

So let's build a valuation that holds up in the 2026 market. Here's the nine-step method I'd use, with a full worked example at the end. It's general information, not financial advice.

Step 1: Calculate clean ARR

Everything starts here, and most sellers get it wrong.

Include in ARR Exclude from ARR
Monthly subscription fees × 12 Setup, onboarding and implementation fees
Annual and multi-year subscription fees (annualized) Consulting and custom development
Committed minimums on usage plans GST, VAT and sales tax
Recurring add-ons One-off usage spikes or overages you can't rely on
Contracts signed but not yet started (report separately)
Tax refunds, grants and R&D offsets

If your billing system reports tax-inclusive revenue, strip the tax out. If you're unsure, my guide to calculating ARR covers the edge cases. And if you bill through Stripe, the Stripe export analyser will rebuild your MRR and churn from a CSV in your browser.

Step 2: Measure the metrics a buyer will ask for

Calculate each of these for the last 12 months, and monthly if you can.

Metric Why it matters A 2026 reference point
ARR growth The biggest driver of the multiple Median bootstrapped SaaS ($3M–$20M ARR): 15%
Net revenue retention Does the base grow on its own? Bootstrapped median: 103%
Gross revenue retention How much leaks out? Bootstrapped median: 91%
Gross margin How much of each dollar is profit at scale? Classic SaaS is high; AI products often lower
Profit or burn Can it fund itself? Rule of 40 is the usual shorthand
CAC payback How efficiently does it grow? Shorter is better
Customer concentration Single-customer risk No client over 10%, top five under 25%

The reference points come from SaaS Capital's 2026 survey of bootstrapped companies, and the concentration rule from the MOATS chapter of my book.

Step 3: Normalize profit

Even if you'll be valued on revenue, buyers will look at profit. Normalize it so it shows what the business would earn under a new owner.

  • SDE (seller's discretionary earnings): profit before the owner's salary and personal benefits, plus one-off and non-cash items. Used for small, owner-run businesses.
  • EBITDA: earnings before interest, tax, depreciation and amortization, after paying market salaries for management. Used for larger businesses.

Common add-backs include one-off legal costs, an owner's salary above or below market, and personal expenses run through the business. Keep evidence for every one. Buyers test them all.

Step 4: Choose the right method for your size and stage

Your business Common primary method Cross-check
Small, founder-run, under about $1M ARR Multiple of SDE Revenue multiple from comparable small deals
Growing, $1M to $20M ARR, team in place Multiple of ARR EBITDA multiple; simple DCF
Mature, profitable, slower growth Multiple of EBITDA DCF; ARR multiple
Fast-growing, venture-backed Multiple of ARR (sometimes forward) Burn multiple; runway

These are common patterns, not rules. A strategic acquirer may ignore all of them and pay for what your product does for their business.

Step 5: Pick a benchmark multiple

For ARR-based valuations, start from current public data and adjust down for private company risk.

  • The SaaS Capital Index median was 4.2x run-rate revenue at 30 September 2026.
  • By growth: 2.3x under 10%, 4.4x at 10–20%, 5.5x at 20–30% (my analysis of the index data).
  • SaaS Capital's 2025 model predicted private multiples at roughly 70–75% of the public figure.

So a private company growing 20–30% might start around 4x (5.5x × roughly 0.72). That's an extrapolation for illustration, not a quoted market price. The full data is in SaaS valuation multiples in 2026.

Step 6: Adjust for quality and risk

Now move the starting multiple up or down. These are the factors I'd score, honestly.

Factor Pushes the multiple up Pushes it down
NRR Above 110% Below 100%
GRR / churn Above 90%, stable cohorts Rising churn, short customer lifetimes
Gross margin High and stable Falling, or heavy AI compute costs
Profitability Rule of 40 above 20, self-funding Large losses, short runway
Size Larger ARR, more customers Small ARR, few customers
Concentration No client over 10% One client paying a third
Founder dependence Team runs sales and delivery Founder holds every relationship
Moat Switching costs, integrations, data Easy to copy, seat-based pricing exposed to AI
Compliance Clean terms and cancellation Flows a regulator would question

There's no formula for the size of each adjustment. That's judgment, and it's what you'll negotiate.

Step 7: Cross-check with a second method

If your ARR multiple says $12 million, test it.

  • Implied EBITDA multiple. Divide the value by normalized EBITDA. If it's 40x, ask whether your likely buyer would ever pay that. A strategic acquirer might. A private equity buyer probably won't.
  • Customer base value. Annual gross profit from existing customers ÷ (annual churn + required return). This is a floor-style check on what the current base alone is worth.
  • Simple DCF. Five years of cash flow plus a terminal value. Useful if the business is profitable and predictable.

If the methods disagree wildly, your assumptions need work, not your spreadsheet.

Step 8: Convert enterprise value to what you actually get

Multiples usually give enterprise value: the value of the business before cash and debt. What lands in your account is closer to equity value.

Equity value ≈ Enterprise value + Cash − Debt ± Working capital adjustments

For SaaS businesses, watch deferred revenue. Customers who prepaid annual plans are owed service the buyer will have to deliver. Some buyers treat part of that balance as debt-like and reduce the price. Agree how it's handled early.

Step 9: Present a range, not a number

A single number invites a fight. A range, with the reasons behind each end, invites a conversation.

"Between $10.5 million and $13 million, depending on how a buyer values our net retention and founder transition" is more credible than "$12 million" and gives you room to negotiate.

A full worked example

These numbers are illustrative.

Valuing a B2B SaaS company with $3.2 million ARR

The business

  • Clean ARR: $3.2 million, growing 20%
  • NRR 105%, GRR 90%
  • Gross margin 78%
  • EBITDA $320,000 (10% margin), so Rule of 40 score of 30
  • Largest customer 7% of ARR; founder is CEO, sales team in place
  • Cash $600,000, debt $200,000, deferred revenue $900,000

Benchmark: growth band 20–30% → public median 5.5x → private starting point about 4.0x

Adjustments (judgment):

  • NRR slightly above the bootstrapped median: +0.2x
  • GRR in line: 0
  • Gross margin a little below classic SaaS: −0.2x
  • Small scale: −0.3x
  • Concentration and team: 0

Adjusted multiple: about 3.7x → enterprise value about $11.8 million Range: 3.3x to 4.1x → $10.6 million to $13.1 million

Cross-check: $11.8 million ÷ $320,000 EBITDA ≈ 37x EBITDA. Plausible for a strategic or growth buyer. A profit-focused buyer would anchor much lower, which tells you who to sell to.

To equity: add $600,000 cash, subtract $200,000 debt, and agree how the $900,000 of deferred revenue is treated. If a buyer treated half as debt-like, equity value at the midpoint would be roughly $11.75 million.

Notice how much of the final number depends on who's buying. That's why the sale process matters as much as the valuation.

Mistakes that ruin SaaS valuations

  1. Using 2021 multiples. The public median was 16.9x in August 2021. It was 4.2x in September 2026.
  2. Inflating ARR with setup fees, services or tax.
  3. Hiding churn behind new sales. Buyers will find it in the cohorts.
  4. Comparing with venture rounds. They price minority stakes, not whole businesses.
  5. Ignoring deferred revenue and working capital.
  6. Valuing a services business as SaaS. If people deliver most of the value, it's services.
  7. Forgetting tax. What you keep after tax is the number that matters.

For Australian founders, there are local factors on top of these, including GST, R&D refunds and the 2027 CGT changes. See valuing an Australian SaaS business.

Frequently asked questions

What metrics do buyers ask for first?

Usually ARR and its monthly movements (new, expansion, contraction, churn), revenue growth, net and gross revenue retention, gross margin, and profit or burn. Close behind come customer concentration, CAC and payback, and cohort retention tables. If you can produce all of these from your billing data in a day, you'll look more credible than most sellers, and the process will move faster.

Should I use ARR or MRR to value my SaaS business?

Multiples are normally quoted on annual figures, so use ARR (or run-rate revenue, which is current monthly revenue times 12). MRR is the same information at monthly scale. What matters is consistency: compare your ARR multiple with benchmarks that use ARR or run-rate revenue, not trailing twelve months or next year's forecast, or you'll be comparing different things.

How do you value a SaaS business that isn't profitable?

On revenue, with heavy weight on growth, retention and how efficiently the business turns cash into new ARR. Buyers will look at your burn multiple and runway, because a business that needs funding to survive is worth less to a buyer who has to supply it. If growth is slow and losses are large, expect a low multiple or a buyer focused on your customers or technology rather than the business.

What is a DCF and do I need one?

A discounted cash flow values a business by forecasting its future cash flows and discounting them back to today at a rate that reflects risk. It's useful as a cross-check, especially for stable, profitable businesses, but it's very sensitive to growth and discount rate assumptions. For most small SaaS sellers, a market multiple plus a simple cross-check is more persuasive to buyers than an elaborate model.

How much does a professional valuation cost?

It varies with the size and complexity of the business and why you need it. A valuation for a sale negotiation can be lighter than one needed for tax, a legal dispute or a shareholder agreement. Ask for a fixed quote and a clear scope. If tax is involved, such as Australia's 2027 CGT changes, make sure the valuer understands why the valuation is needed.
