How it works
Total requests = users × sessions × requests. Upstream = total × (1 − cache). Cost = upstream ÷ 1,000 × rate.
AI and infrastructure
API request budget calculator
Estimate monthly upstream API requests after caching and their cost at your entered billable unit rate.
- Estimated API cost
- $50.00
- Total requests
- 100,000
- Upstream requests after caching
- 50,000
- Requests avoided by caching
- 50,000
Cache only reduces avoided billable requests. Excludes cache cost, retries, background tasks, and token-based billing.
Worked example
1,000 users × 20 sessions × 5 requests = 100,000; 50% cache leaves 50,000 upstream. At 1/thousand, cost is 50.
Assumptions and limits
Cache only reduces avoided billable requests. Excludes cache cost, retries, background tasks, and token-based billing.
Frequently asked questions
How do I use the api request budget calculator?
Estimate monthly upstream API requests after caching and their cost at your entered billable unit rate.
Does 100% caching eliminate infrastructure costs?
No. It only eliminates upstream requests in this model; storage, cache reads, and execution may still cost money.
Do I need an account and are my inputs uploaded?
No account is required. Calculations run in your browser. Entered numbers and text are not included in tool analytics events; only the tool ID, language, and action are recorded.
