Most founders undercharge for years before finally raising prices — and then find the churn was far lower than feared. Here is a practical framework.
The math on acceptable churn
If you raise prices 20% and lose 10% of customers, you net +8% more revenue. ($100 → $120 per customer × 90 customers = $108 vs. $100). The break-even churn rate for a 20% price increase is: churn ≤ price increase / (1 + price increase) ≈ 16.7%.
Below that, the increase is accretive even with significant attrition.
Pricing increase playbook
- Grandfather long-term customers at existing rates for 6–12 months
- Communicate value, not cost: explain what they get, not what they'll pay
- Give 30–60 days notice — surprises cause churn, preparation does not
- Offer annual lock-in: let customers lock today's price annually
- Test on new cohorts first: raise prices for new customers before existing
When to raise prices
- NPS is consistently > 50
- Payback period < 12 months (you can afford attrition)
- CAC is rising but ACV is flat
- You are the cheapest option in your category
