How much is bad UX costing
your SaaS MRR every month?
The average SaaS product loses 15–30% of potential MRR to fixable UX friction — poor trial onboarding, unclear upgrade paths, and confusing pricing. This calculator shows you the exact number and what it costs annually.

Why UX friction is expensive in SaaS.
Each 1% improvement in trial conversion is worth more than you think
For a SaaS with 1,000 monthly trial starts and $100 MRR per customer, improving trial conversion from 4% to 5% adds $1,200 MRR — every single month, compounding.
Churn is mostly a UX problem in disguise
Research shows that 70% of churn in the first 90 days is caused by poor onboarding — users who never reached their aha moment. Better UX reduces churn before support tickets are ever filed.
Upgrade friction is the most underestimated leak
Most SaaS products invest heavily in acquisition but ignore the friction between free and paid. A confusing upgrade flow, unclear plan comparison, or buried upgrade CTA can cost 30–50% of potential upgrade revenue.
Common questions
What SaaS metrics should I use in this calculator?
Use your monthly unique trial starts as visitors, your trial-to-paid conversion rate, and your average MRR per customer as revenue per conversion. For churn impact, use your monthly active user count and monthly churn rate.
Our trial conversion is 3%. Is UX the main problem?
At 3%, UX is almost always a significant factor. Industry median is 3–5%, but top SaaS products with good onboarding reach 10–15%. The calculator shows what closing that gap is worth in monthly revenue.
How does the calculator account for churn, not just conversion?
The Revenue Leak calculation factors in both acquisition friction (visitors who never start a trial) and retention friction (trial users who convert but churn quickly due to poor onboarding). The combined number shows the full UX cost.
