Churn tolerance: Find how many customers a price increase can lose before gross profit declines.
Age 5Explain it to a 5-year-oldStart with a picture
Imagine using Churn tolerance to answer this question: find how many customers a price increase can lose before gross profit declines? Enter Current price, Proposed price, Variable cost per customer, and 1 other input; the calculator shows Break-even retained customers. Try changing one number and watch what happens to Break-even retained customers. The answer tells you Break-even retained customers.
Age 15Explain it to a 15-year-oldConnect it to the formula
This isolates price, variable cost and customer count. It does not estimate actual churn, acquisition effects, usage changes or customer lifetime value. The rule is Break-even retained customers = old customers × old unit contribution ÷ new unit contribution. Its input values are Current price, Proposed price, Variable cost per customer, Current customers, and the main result is Break-even retained customers. Try changing one number and watch what happens to Break-even retained customers.
CollegeExplain it at college levelState the model precisely
This tool models one operating decision from explicitly supplied company assumptions. The implemented relation is Break-even retained customers = old customers × old unit contribution ÷ new unit contribution, evaluated from Current price, Proposed price, Variable cost per customer, Current customers to produce Break-even retained customers. This isolates price, variable cost and customer count. It does not estimate actual churn, acquisition effects, usage changes or customer lifetime value. The model omits unentered taxes, cash timing, legal constraints and market uncertainty. Compare the output with company records and a downside scenario before committing resources.
The decision this tool supports
Find how many customers a price increase can lose before gross profit declines.
Why the business model works
This isolates price, variable cost and customer count. It does not estimate actual churn, acquisition effects, usage changes or customer lifetime value.
Inputs and operating assumptions
This model uses Current price (at least 0), Proposed price (at least 0), Variable cost per customer (at least 0), Current customers (at least 0.01). Keep currencies, accounting treatment and time periods consistent with one another.
The formula
Break-even retained customers = old customers × old unit contribution ÷ new unit contribution
What the calculator produces
The primary output is Break-even retained customers; it also exposes Maximum customers lost, Maximum churn tolerance, Current gross profit. Change one assumption at a time so the comparison remains explainable.
Before using the result in a decision
This compact model cannot capture every tax, accounting, legal, market or operational condition. Compare the output with current company records, cash timing and the downside scenario before committing resources.
