Raising prices is one of the highest-leverage moves in any subscription business — but founders underdo it or avoid it entirely because they fear churn. This calculator makes the math explicit: given your current pricing and customer count, exactly how many customers can you afford to lose at the new price and still come out ahead?
The break-even retention formula
Break-even retention = Current MRR ÷ (New Price × Current Customers)
If you have 100 customers at $49/month ($4,900 MRR) and raise to $69/month, you need to retain 4,900 ÷ 6,900 = 71% of customers. In other words, you can lose 29% of customers and still earn more revenue.
What research says about B2B price increases
Price elasticity in B2B SaaS is much lower than in consumer markets. Studies consistently find: - 5–15% price increases: 0–5% customer loss in B2B - 20–30% price increases: 5–15% customer loss in B2B, depending on value perception - 50%+ price increases: significant churn unless clearly value-justified
How to execute a price increase
- Grandfather existing customers for 6–12 months — reduces churn dramatically
- Announce 60–90 days in advance with a value-focused message
- Apply immediately to new customers — test the new price with no risk
- Track conversion rates after the change — lower conversion may signal positioning issues
Frequently asked questions
Should I raise prices on all plans at once? Test the highest tier first. Enterprise/power users are least price-sensitive and provide the most useful signal. Once you see the churn data, apply to lower tiers with greater confidence.
What if customers cancel after the price increase? Customers who cancel over a modest price increase were usually already considering leaving. A price increase often cleans up a customer base — churned customers at the new price are replaced by higher-quality customers acquired at the new price point.
