SaaS Valuation Calculator: How to Estimate What Your SaaS Is Worth
Learn the formula behind SaaS valuations — how to estimate your multiple, what factors adjust it, and why the number is just a starting point.

A SaaS valuation calculator gives you a starting point, but understanding what goes into the calculation is more useful than any single output number. Here is the logic behind it.
The Basic Formula
Estimated valuation equals ARR multiplied by a multiple. ARR is your monthly recurring revenue multiplied by 12. The multiple is typically somewhere between 3x and 8x for small and indie SaaS products, depending on a handful of key factors. For an in-depth breakdown of why a multiple is the right tool here, see SaaS revenue multiples explained; for typical 2026 ranges by MRR tier, see SaaS valuation multiples in 2026.
Estimating Your Multiple
| Factor | Adjustment |
|---|---|
| Baseline (stable revenue) | 3x |
| Monthly churn below 5% | +0.5x to 1x |
| MRR growing month over month | +0.5x to 1x |
| Primarily organic traffic | +0.5x |
| Documented SOPs, low owner dependency | +0.5x |
| Churn between 5% and 8% | No adjustment |
| Churn above 8% | -0.5x to 1x |
| Declining MRR | -1x to 1.5x |
| Heavy owner dependency, no documentation | -0.5x to 1x |
A Quick Example
A product with $3,000 MRR has $36,000 ARR. If churn is around 4%, MRR has grown for several months, traffic is primarily organic, but there are no documented SOPs, you might land around 4x. That gives an estimated valuation of around $144,000.
This is a rough estimate, not a precise appraisal. But it gives you a defensible starting point for a conversation.
Why the Calculator Is Just the Beginning
Buyers do not use a formula in isolation. They look at the full picture: trends, context, what the business can become. The formula gives you a number to anchor around, but the actual price is shaped by how well you present the data and how many buyers are engaged at the same time.
Verified metrics, clear documentation, and the ability to explain your weak spots openly rather than hiding them all shift buyer perception, and buyer perception is what drives the final number. Once you have a number you trust, our guide to selling a SaaS business covers prep, listing, and closing.
