How it works
New MRR = payers × (1 − loss) × new price. Break-even loss = 1 − current price ÷ new price.
Revenue and pricing
Subscription price increase calculator
Compare MRR before and after a price change and calculate the maximum payer loss that would preserve current revenue.
- MRR after price change
- $5,400.00
- Previous MRR
- $5,000.00
- Revenue change
- $400.00
- Break-even payer loss
- 16.67%
Loss is an assumption. Does not include new customer effects, phased migration, discounts, or support costs.
Worked example
100 payers at 50 produce 5,000. At 60, after 10% loss, the remaining 90 produce 5,400.

Frequently asked questions
How do I use the subscription price increase calculator?
Compare MRR before and after a price change and calculate the maximum payer loss that would preserve current revenue.
Does break-even loss also work for price cuts?
A price cut gives a negative loss limit: you would need a larger customer base to preserve MRR. This is not a demand forecast.
Do I need an account and are my inputs uploaded?
