Revenue

Net per month: $600.00
Gross per day: $20.00
Gross per month (30 days): $600.00
Fees per month: $0

Pay per call or subscription

Break-even calls per month: 4,900
That customer pays per call: $15.00

A customer who makes fewer than 4,900 calls a month pays less per call than on the $49.00 plan. At 1,500 calls, pay per call is cheaper for them.

x402 is an open protocol for paying per request: the server answers HTTP 402 with a price, and the client pays and retries. This calculator holds no fee data, so enter your own facilitator and network costs. Runs in your browser, nothing is sent anywhere.
