SaaS Valuation Guide: What\'s Your Software Business Worth?
SaaS valuations depend on your size, growth rate, and key metrics. This guide covers ARR vs. SDE multiples, the Rule of 40, the metrics that matter most, and real examples of what SaaS businesses sell for.
ARR Multiples vs. SDE Multiples: Which to Use
SDE Multiples (Under $1M ARR)
For bootstrapped SaaS businesses under $1M in annual recurring revenue, use SDE multiples. This is the same approach used for other small businesses - take your total owner profit and multiply it.
Typical range: 3-5x SDE
Best for: solo-founder SaaS, lifestyle businesses, niche tools with stable revenue.
ARR Multiples (Over $1M ARR)
For SaaS businesses above $1M ARR, revenue multiples become standard. At this scale, buyers are paying for recurring revenue, growth potential, and market position - not just current profit.
Typical range: 4-12x ARR
Best for: growing SaaS with team, funded businesses, B2B platforms with expansion revenue.
In the transition zone ($500K-$1.5M ARR)? Both methods may apply. Your advisor will present the business using whichever framing yields the best outcome. Our free valuation calculator handles both approaches.
The Rule of 40 Explained
The Rule of 40 is a quick health check for SaaS businesses. It says your annual revenue growth rate + profit margin should exceed 40%. It\'s a simple way for buyers to assess whether your SaaS balances growth with profitability.
High Growth
50% growth + (-5%) margin = 45%
Growing fast, burning some cash. Buyers accept this if the unit economics are strong.
Balanced
30% growth + 20% margin = 50%
Strong growth with healthy profitability. This is the sweet spot that commands premium multiples.
Profitable
10% growth + 35% margin = 45%
Mature and highly profitable. Attractive to PE buyers who value cash flow over growth.
Why it matters: SaaS businesses that pass the Rule of 40 typically sell for 20-40% higher multiples than those that don\'t. It\'s not a hard rule, but it\'s a benchmark every serious buyer will calculate.
Key SaaS Metrics Buyers Care About
These are the metrics every SaaS buyer will ask for. Know your numbers before you go to market.
MRR / ARR
Monthly and Annual Recurring Revenue. The foundation of your valuation. Buyers want to see consistent growth month over month.
Monthly Churn
The percentage of customers who cancel each month. Under 2% is excellent. Over 5% is a red flag that signals product-market fit issues.
Net Revenue Retention
How much revenue you retain from existing customers including upsells. Over 100% means customers spend more over time. Over 120% is exceptional.
CAC (Customer Acquisition Cost)
How much it costs to acquire one customer. Compare to LTV to see if your growth is efficient. Payback period under 12 months is ideal.
LTV (Lifetime Value)
Total revenue from an average customer over their lifetime. Higher LTV means more profitable customers and justifies higher acquisition spending.
CAC Payback Period
How long it takes to recoup the cost of acquiring a customer. Under 12 months is good. Under 6 months is exceptional.

What Kills SaaS Valuations
These are the most common issues that destroy SaaS valuations or kill deals outright:
Frequently Asked Questions
When should I use ARR multiples vs SDE multiples for my SaaS?
Under $1M ARR, use SDE multiples (3-5x). Above $1M ARR, revenue multiples become standard (4-12x ARR). The shift happens because larger SaaS companies are valued on growth and recurring revenue potential rather than just current profit.
What is the Rule of 40 and why does it matter?
The Rule of 40 says your growth rate plus your profit margin should exceed 40%. For example, 30% growth and 15% margins equals 45%, which passes. It matters because it shows buyers your SaaS balances growth with profitability - companies that pass the Rule of 40 command premium valuations.
What SaaS metrics do buyers care about most?
Monthly churn rate (under 3% is good, under 2% is great), net revenue retention (over 100% means existing customers spend more over time), LTV to CAC ratio (above 3:1 is healthy), and CAC payback period (under 12 months is ideal). These four metrics together tell the story of a healthy SaaS business.
Does technical debt affect my SaaS valuation?
Yes, significantly. Buyers will review your codebase during due diligence. Significant technical debt - outdated dependencies, poor architecture, no tests, security vulnerabilities - can reduce your multiple by 1-2x or even kill the deal. Clean, well-documented code is a major value driver.
How does customer concentration affect SaaS valuation?
If any single customer makes up more than 10-15% of your revenue, it is a risk factor that reduces your multiple. If one customer is 25% or more, some buyers will walk away entirely. The ideal is no single customer above 5% of total revenue.
