You can lose up to this many accounts and still generate equal or greater gross revenue.
About this tool
Most mature SaaS products are underpriced relative to the economic value they deliver. However, founders frequently delay necessary price increases out of fear that existing customers will churn in protest. The mathematics of price elasticity reveal that a business can absorb a surprising amount of customer attrition during a price hike and still come out significantly ahead in net revenue. For example, if you increase prices by 30% from $50 to $65, you can lose up to 23% of your customer base before your gross revenue drops below its previous level. Use this simulator to determine your exact tolerable churn threshold before executing a price adjustment.
How It Works

- 2Input your proposed new monthly subscription price.
- 3Input your current active customer count.
- 4Review the price increase percentage, the maximum tolerable churn rate before revenue declines, and the projected upside assuming zero churn.
Formula & Math
Transparent LogicMax Tolerable Churn (%) = (1 - (Current Price / New Price)) × 100
Worked Practical Example
A project tool charges $50/month to 500 customers ($25,000 MRR) and raises pricing to $75/month (a 50% increase).
Calculation / Steps
Max Tolerable Churn = (1 - ($50 / $75)) × 100 = (1 - 0.6667) × 100 = 33.33%
Expected Result
Can lose up to 33.3% of customers (166 accounts) before losing revenue. At 5% actual churn, revenue rises to $35,625 MRR (+$10,625/mo).
Frequently Asked Questions
Should I increase prices on existing grandfathered customers?+
Best practice is either grandfathering existing accounts for a set duration (e.g. 12 months) or offering a legacy discount, while applying the new rate immediately to new signups.
How much advance notice should I give before a price increase?+
Provide at least 30 to 60 days advance written notice via email, clearly articulating the new features and infrastructure delivered since their signup.
What should I do if a customer threatens to cancel over a price hike?+
Have an automated retention flow ready to offer a temporary extension at their legacy rate or transition them to an annual commitment.
Automate retention on your cancel button
BoolBul provides a vital safety net during price hikes: if legacy users click cancel, BoolBul can automatically present an offer to keep their old rate.
