TLDR: Most SaaS founders undercharge, and the fear that any price increase will spike churn is usually overblown.
- A price increase comes out ahead as long as churn stays under the breakeven: a 10% increase survives ~9% churn, a 20% increase survives ~17% churn.
- Real-world price-increase churn is often lower than the breakeven, so raising prices is frequently net-positive.
- Do it safely: raise new-customer prices first, grandfather existing customers for a period, communicate the added value, give 30-60 days notice.
- Do not raise prices to paper over churn caused by weak value. Fix that first.
Pricing is the highest-leverage number in SaaS and the one founders touch least. A 10% price increase, if it survives, drops almost entirely to the bottom line. There is no acquisition channel that efficient.
What churn can a price increase actually survive? (calculator)
The decision is not "will it cause churn." It will. The decision is "will more churn than the breakeven happen." Move the sliders.
Price increase breakeven
Applied to your whole base. Shows the net revenue change and the churn you can tolerate.
Where these numbers come from: the breakeven churn for a price increase of p is simply p / (1 + p). A 10% increase breaks even at 9.1% churn, a 20% increase at 16.7%, a 30% increase at 23.1%. As long as the share of customers who cancel because of the increase is below that line, you make more money with fewer customers, which also lowers your support load. The catch the formula hides: this assumes the churn is a one-time reaction, not a permanent lift to your ongoing churn rate. If the increase makes your product feel overpriced long-term, the damage compounds. That is why value has to justify the price.
