Example scenario

  • 500,000,000 requests/month at $1.00 per 1M requests ≈ $500/month.

Included

  • Request-fee estimate from requests/month and $ per 1M requests pricing.
  • Useful for API gateways, serverless, and request-metered services.

Not included

  • Data transfer/bandwidth costs (model separately).
  • Minimums, free tiers, and tiered steps unless you reflect them in inputs.

How we calculate

  • Request cost = (requests per month ÷ 1,000,000) × price per million requests.
  • Use your provider’s definition of billable requests and any request classes.
  • This tool ignores data transfer; model bandwidth separately if relevant.

FAQ

Should I use total requests or only billable requests?
Use billable requests (some providers exclude cache hits, errors, or internal calls depending on the product).
