How to Value a SaaS Company for Sale (The Method I Use on Every Deal)

I named a number out of thin air.

That was my first exit. Software business, barely 16 months old. One buyer. No competing offers. No valuation framework. I named a number, they said yes, and I walked away thinking I'd done well.

I hadn't. I was negotiating blind. I had no idea what my company was actually worth — or what I could have gotten if I'd understood the market.

That's the story I tell founders when they come to me and say, "I think my SaaS is worth around X." My first question is always the same: "How did you arrive at that number?"

Most of the time, the answer is: "I read something online." Or: "I know someone who sold for X multiple." Or: "I ran it through a calculator."

Here's the thing. Those starting points are fine. They give you a range. What they don't give you is the thing that sets the actual price — a real buyer, competing against other real buyers, making a real offer on your specific business.

This is how SaaS businesses are actually valued for a sale. Not in theory. In practice.

Start Here: Two Methods, One Choice

SaaS businesses are valued using one of two methods, depending on deal size.

SDE-based valuation is used for smaller deals, roughly under $5M in purchase price. SDE stands for seller's discretionary earnings. You take the business's net profit and add back the owner's salary, personal benefits, and any discretionary expenses that a new owner wouldn't carry. That's your true economic output. You apply a multiple to it.

EBITDA or ARR-based valuation is used for larger businesses — typically above $5M in exit value, and more commonly in the $10M+ range. EBITDA strips out interest, taxes, depreciation, and amortization but does NOT add back the owner's salary, because a business at this size needs a management team whether or not the founder is there. ARR multiples are used when the business has enough recurring revenue that buyers are underwriting future cash flows, not just trailing earnings.

The practical rule: if your SaaS generates under $2M–$3M in ARR and is owner-operated, buyers and lenders will look at SDE first. If you've crossed $5M ARR with a real team behind you, expect the conversation to shift to ARR and EBITDA multiples.

Knowing which applies to your business before you have your first buyer conversation matters. It changes how you present the financials.

The Multiple Is the Output — Not the Starting Point

Every founder wants to know the multiple. I understand why. It feels like the number.

It isn't.

The multiple is what buyers are willing to pay after they've evaluated your business against every risk they can identify. It's the summary of a much longer due diligence process compressed into a single ratio.

Twenty-seven different factors go into valuing and selling a business properly. Revenue and profit are two of them. The other twenty-five either push your multiple up or pull it down.

Here's what drives a SaaS multiple in either direction.

What pushes multiples up:

• Net revenue retention above 100% (existing customers expand their spend over time)
• Monthly churn below 1%
• Consistent year-over-year revenue AND profit growth
• No single customer representing more than 15–20% of ARR
• Diversified acquisition channels (not dependent on one ad platform or one sales rep)
• A team that runs the business without the founder's daily involvement
• Clean, accrual-based financials with a clear audit trail
• Remote-operable — a buyer can manage the business from anywhere

What suppresses multiples:

• Monthly churn above 2–3%
• Customer concentration — one or two clients making up most of ARR
• Owner dependency — the founder IS the product, the sales motion, the key relationships
• Platform dependency — 90% of leads come from one channel that could change overnight
• AI exposure risk — if a new AI tool can replace the core function of your product at $20/month, buyers and lenders see that risk
• Messy financials — cash-basis accounting, inconsistent categorization, unverifiable addbacks
• Declining revenue or flat growth

The spread between a business at the top of those lists and one at the bottom is significant. I've seen two SaaS businesses with identical ARR sell for 3x and 8x respectively. Same revenue. Completely different buyer competition. The metrics, the risk profile, and the process created the gap.

The SaaS Metrics Buyers Obsess Over

If you want to understand where your valuation sits before talking to buyers, here are the metrics that matter most in a SaaS deal.

Monthly churn rate. The percentage of customers who cancel each month. Under 1% is strong. Above 3% starts to concern buyers. High churn tells a buyer the product has a retention problem — and they'll model that into their offer or walk away.

Net revenue retention (NRR). This is the one metric that can push a SaaS multiple above the market average. NRR above 100% means your existing customers are spending more each year than the year before — expansions and upsells outpace cancellations. Buyers love NRR above 100% because it signals a business that grows without adding new customers.

Customer acquisition cost vs. lifetime value. How much does it cost to acquire a customer? How long do they stay and how much do they pay? A healthy LTV:CAC ratio tells buyers you have a repeatable, efficient growth engine. A bad one tells them the growth you're showing isn't sustainable.

Gross margin. SaaS businesses typically carry high gross margins — 70–85% is common. If yours is significantly below that, buyers want to know why. Infrastructure costs, heavy customer success overhead, and third-party dependencies all compress margins and affect the multiple.

Owner hours per week. This is not a financial metric, but it functions like one. A founder spending 50 hours a week on the business is a risk a buyer has to price. A business that runs on 10 hours a week of founder time is worth more. Not because the revenue is different — because the risk profile is different.

What Lenders See That Buyers Don't Always Say Out Loud

Here's something most SaaS founders miss: the buyer's enthusiasm and the lender's approval are two separate things.

A buyer can fall in love with your business and make a strong offer. The lender can still kill the deal.

Lenders underwrite against downside scenarios. They're not buying the upside story. They're asking: if everything that could go wrong does go wrong — one large customer churns, ad costs spike, the founder leaves — can this business still service the debt?

Customer concentration is the issue that kills the most SaaS deals at the lender level. If your largest customer represents 30% of ARR, a lender sees that as a single event risk. If that customer churns, revenue drops 30% instantly. The business might not cover loan payments. The deal either restructures or dies.

Before you go to market, understand what your business looks like through a risk lens, not just a growth lens. Those are two different stories, and you need to be able to tell both.

How the Calculator Fits In

A SaaS valuation calculator gives you orientation. You plug in your ARR, your growth rate, your churn, and your margins, and it returns a range based on current market comps.

Use the SaaS Valuation Calculator here to run your numbers.

That range is useful. It tells you whether you're in the right conversation or completely off. If you're expecting $10M and the calculator says $2M–$4M, there's a gap worth understanding before you waste six months in a process that won't get you there.

But here's what no calculator can give you: the actual market price.

The actual price is set by competing buyers making real offers on your specific business. I've seen businesses sell for significantly above the top of what any calculator would have estimated, because the right strategic acquirer showed up and decided your customer list or your product IP was worth more to them than any financial model would suggest.

The calculator tells you the floor and the midpoint. A real competitive process — where multiple buyers are engaged simultaneously — is what tells you the ceiling. And the ceiling is where maximum exit lives.

The Number That Actually Matters

Before any of the multiples conversation, there's a question I ask every founder: what do you need from this exit?

Not what do you think the business is worth. Not what someone told you it should be worth. What do you actually need — after taxes, after fees, after the wire hits — to fund the next chapter?

Most founders haven't done that math. They've done the revenue-times-multiple math. They haven't reverse-engineered from the destination.

Here's why it matters. If you need $5M after taxes to accomplish your goal, and your business at current metrics supports a $4M exit, there are two choices: go to market now and take the $4M, or spend 12–18 months strengthening the metrics that move the multiple and go to market at $6M–$7M.

That's a real decision. It changes the timeline. It changes the preparation. It changes whether you want to wait.

My job is to help founders understand exactly where they sit — the probable pricing range, the factors that would move it, and whether the work to get there is worth it. Some founders are better off selling now. Some are better off waiting. That answer is different for every business.

But you can't make that decision if you don't know the real number.

That's what a valuation is for.
