Subscription Cost Per Use: a worked example
The values below are an illustrative example, not a recommendation. Replace them with measurements or assumptions that match your question.

- The result is 5 per use, rounded for display.
How to interpret your result

Agree the splitting rule before calculating: equal shares and income-based shares reflect different choices. Keep expenses on the same billing period and account for currency rounding when dividing a bill.
