Most SaaS founders know their trial conversion rate. But they never run the SaaS trial conversion math on what those unconverted trials actually cost.
It's not just one missed payment - every lost SaaS trial is a customer who would have paid you month after month.
Plug in your numbers below. This MRR calculator works out how much your trial conversions add, how much you're leaving on the table, and how much a small improvement would be worth.

How this is calculated
New MRR = converting SaaS trials per month x monthly price. Lost MRR = unconverted SaaS trials per month x monthly price. ARR = MRR x 12. These figures show the recurring revenue added (or missed) each month and do not account for churn. These are simplified estimates. Actual revenue depends on plan mix, expansion revenue, annual contracts, and other factors.
Frequently Asked Questions
What is a good SaaS trial conversion rate?
A typical SaaS trial conversion rate falls between 15% and 25%, but it varies widely depending on your product, pricing, and trial length. PLG products with shorter trials often convert higher because users self-select. If you're below 10%, there's usually room to improve onboarding or trial messaging.
How is trial conversion rate calculated?
Trial conversion rate = (number of trials that became paid customers / total number of trials) x 100. For example, if 50 people start a trial and 8 convert to a paid plan, your conversion rate is 16%. Track this monthly to spot trends.
What's the difference between MRR and ARR?
MRR (Monthly Recurring Revenue) is the total predictable revenue you collect each month from active subscriptions. ARR (Annual Recurring Revenue) is simply MRR multiplied by 12. MRR is more useful for tracking month-to-month growth, while ARR is commonly used when reporting to investors or benchmarking against other SaaS companies.
