Break-even loss for other increases
The share of customers you can lose before gross profit falls, by size of increase and gross margin. Downgrades as you set them. Your case is circled.
How this tool works
What it does
It works out how many customers you can lose after a price increase before gross profit falls. It weighs the extra margin from customers who stay against the margin you lose from customers who leave or move to a cheaper plan.
Use it before you announce an increase, to set a limit on acceptable losses. Use it again after a quarter, with your real losses.
What you enter
- Customers and average price. Today's paying customers and what one pays per month on average.
- Gross margin. Revenue minus the variable cost of serving a customer. Hosting, support and payment fees count. Salaries of the product team usually don't.
- Price increase and who gets it. The rise in percent, and the share of customers it applies to.
- Expected reaction. Your estimate of customers who leave, and of those who stay on a cheaper plan.
What you get
- Break-even loss. The share of affected customers you can lose before monthly gross profit drops below today's.
- The balance. Monthly gain from customers who pay more, against monthly loss from those who leave or downgrade. The beam tips toward the bigger side.
- The chart. Gross profit and revenue change across 0 to 40% of customers lost. The marked points show break-even and your estimate.
- Minimum increase. The smallest increase that still adds gross profit at your expected losses.
The maths, assumptions and sources
Gross profit per customer is price × gross margin. After an increase of p, a customer who stays brings price × (gross margin + p), because variable cost doesn't change. With no downgrades, break-even loss = p ÷ (gross margin + p). So a 10% increase at a 75% gross margin breaks even at 11.8% of customers lost. Downgrades lower that limit.
The tool assumes variable cost per customer stays the same for customers on the cheaper plan, and that customers who leave are gone for the full year. It doesn't model any change in how many new customers you win at the higher price.

- Break-even volume after a price change: % change in volume = −price change ÷ (contribution margin + price change). See Impact Pricing.
