What is break-even churn for a price increase?
This SaaS price increase break-even churn calculator helps you find the customer-loss threshold that keeps recurring revenue steady.
Break-even customer loss is the fraction of customers that can leave after a price increase before modeled recurring revenue falls below its original level. It is a revenue threshold, not a prediction of customer behavior.
One-time loss, not monthly churn
The loss input describes the cumulative effect of one price-change scenario. Do not interpret it as a recurring monthly churn rate compounded indefinitely.
How to use the calculator
Enter a homogeneous customer group, its current monthly price, a higher proposed price, and a possible loss percentage. Use separate calculations for plans with materially different pricing.
Compare on the same basis
Keep discounts, seats, and billing frequency consistent. If customers have different contract values, customer-count loss is not the same as revenue churn.
Step-by-step planning checklist
- Select customers on the same plan and billing basis.
- Enter the current monthly price, higher proposed price, and one cumulative customer-loss assumption.
- Compare both the theoretical percentage and the maximum whole-customer loss.
- Run several scenarios rather than treating the threshold as evidence of how customers will respond.
Formula and worked example
For 100 customers moving from $100 to $120 monthly, the theoretical threshold is 16.67%. At least 84 whole customers must remain to keep revenue at or above $10,000. A 10% loss leaves an expected 90 customers and $10,800 MRR, an $800 increase.
Understand the rounding
The theoretical threshold is continuous. The whole-customer result rounds retained customers upward, so losing 17 customers in this example would fall below the original revenue.
Use the result carefully
Test several loss scenarios and compare them with customer feedback, contract terms, and observed renewal behavior. Revenue staying level does not imply customers are equally satisfied or that the change is strategically sound.
What the model excludes
Costs, expansion, new customers, grandfathered contracts, delayed renewals, and changing usage are excluded. Profit break-even requires a separate cost model.
Frequently asked questions
Is this a churn forecast?
No. It shows the arithmetic threshold and the result of the loss assumption you enter.
Use customer research and renewal data to judge plausible loss assumptions. The threshold only shows where the arithmetic changes, not where retention will land.
Can I compare a price decrease?
No. This specific tool requires a higher proposed price. A price decrease needs an acquisition or volume-growth model.
To evaluate a lower price, model the additional customers or usage needed to recover the revenue reduction. That is a different question from tolerable loss after an increase.
Why are there two customer-loss figures?
The percentage threshold is continuous, while the maximum whole-customer loss respects indivisible customer counts.
At a $100-to-$120 change for 100 customers, losing 16 still leaves $10,080 MRR, while losing 17 leaves $9,960. Whole-customer rounding matters.
Does it measure profit?
No. The calculation compares recurring revenue and excludes delivery and operating costs.
Retaining the same revenue with fewer customers may change costs, but the model does not assume what those costs will be. Analyze margin separately.
Can I apply this to mixed plans?
Run each comparable price cohort separately. A single average can hide different retention and contract-value patterns.
A loss concentrated in your largest accounts can be more damaging than the same count of small accounts. Use comparable price groups and review revenue exposure.
