How to Value a SaaS Business: Multiples, Metrics & Method

Ask ten founders what their SaaS is worth and you'll get ten confident answers and very little agreement. The truth is that SaaS valuation is less mysterious than it looks: almost every deal comes down to a multiple applied to a measure of revenue or profit, adjusted up or down for risk. Once you understand which multiple applies and what moves it, you can estimate a defensible number in an afternoon.

The two multiples that matter

Smaller SaaS businesses are usually priced on one of two bases, and which one applies depends mostly on size:

• Revenue multiple (ARR or TTM revenue) — common for growing products where profit is intentionally thin because the founder reinvests. Expressed as a multiple of annual recurring revenue, e.g. 3× ARR.
• Profit multiple (SDE or EBITDA) — common for mature, profitable products run lean. Seller's Discretionary Earnings (owner profit plus add-backs) times a multiple, e.g. 3.5× SDE.

As a rough rule, micro-SaaS under roughly $100k in annual profit tends to trade on an SDE multiple, while faster-growing products with meaningful ARR trade on a revenue multiple. Some buyers will look at both and take the higher of the two as a sanity check.

What actually moves the multiple

Two SaaS businesses with identical revenue can sell for very different prices. The gap is risk and quality of earnings. Buyers pay more for:

• Growth — a product growing 10%+ month over month commands a premium; flat or declining revenue compresses the multiple hard.
• Low churn — sticky, mission-critical products with high net revenue retention are worth more than leaky ones.
• Revenue concentration — if one customer is 40% of revenue, that's a discount; broad, diversified revenue is a premium.
• Owner independence — a business that runs without the founder's daily involvement is far more valuable than one that is the founder.
• Verifiable financials — numbers a buyer can confirm from a payment processor are worth more than a spreadsheet they have to trust.

The single cheapest thing a seller can do to raise their multiple is make their revenue verifiable. Trust is a discount you don't have to give.

A step-by-step method

1. 1Pick the basis. Under ~$100k annual profit, start with SDE; for higher-growth products with real ARR, start with a revenue multiple.
2. 2Calculate the base figure. For SDE, take net profit and add back owner salary and one-off, non-essential costs. For ARR, annualize current MRR.
3. 3Choose a starting multiple from comparable sales in your category and size band — then adjust up for strong growth, low churn, and owner independence, and down for the opposite.
4. 4Cross-check against real comparables. Look at what similar products in your category and price tier are actually listed and sold for.
5. 5Sanity-check the implied payback. A buyer is asking 'how many years until this pays for itself?' If your multiple implies an unreasonable payback for the risk, expect pushback.

On StackTrade you can ground every step in live data. Browse your category and price tier to see what comparable products ask, and the marketplace surfaces the implied revenue multiple on each listing so you're comparing like with like.

Let an AI agent pressure-test your number

Because StackTrade exposes its market data over the Model Context Protocol, you (or a buyer) can ask an AI agent to pull category-level valuation analytics — median and average multiples, price ranges, and recent comparable sales — and reason over them. It's the fastest way to check whether an asking price is inside the market or fantasy.

Valuation isn't about finding one perfect number; it's about landing in a defensible range and being able to show your work. Pick the right basis, adjust honestly for risk, anchor to real comparables, and make your financials verifiable — and you'll spend negotiation time on terms instead of arguing about whether the price is sane.
