How to calculate break-even customer count
This calculator finds how many customers are needed to break even, based on monthly fixed costs and the contribution each customer provides — useful for subscription or recurring-revenue business models.
How the calculation works
Break-even customers = ceil(Monthly fixed costs ÷ Contribution per customer).
Example
$15,000 in monthly fixed costs with $45 contribution per customer: ceil(15,000 ÷ 45) = ceil(333.3) = 334 customers.

Pro Tips for Break-Even Customer Count

Common Break-Even Customer Count Mistakes to Avoid
- Using average revenue per customer instead of contribution per customer (after variable costs), which would understate the true number of customers needed.
