How many customers can a price rise lose?

Put in each plan's customers and its old and new price, and the churn you expect. See the new monthly revenue, how many customers could leave before the rise loses money, where you stand a quarter later, and what grandfathering or an annual lock-in offer costs or earns over a year.

Illustrations, not benchmarks. Your billing system has the real counts.

Your plans

Monthly prices. For an annual plan, put the price a month. Leave a row empty if you don't need it.

Before you send the email

Read your own terms for the notice a price change needs and whether it can apply mid-term, and give annual customers the new price at renewal. Call your largest customers a week before the announcement. Say the old price, the new price, the date and the effect on the next invoice in the first two lines, and make the way out plain.

What Slack, Atlassian and Unity did, the notice rules, a sample email and how to measure the rise a quarter later are in our article raising prices on customers you already have. If the question is what you charge for rather than how much, try the billable unit comparison.
