Formula
- Use the units shown beside each field.
- Results update automatically whenever you change an input.
- Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
- Steady-state model, not a burst scheduler. Server variability, retries, distributed quotas and network limits are excluded.
Example Calculation
- Requests allowed per window: 600
- Window length: 60 s
- Concurrent workers: 4
- Mean request duration: 0.5 s
600 requests per minute allow 10/s, but four workers taking 0.5 s each limit the model to 8/s.
Frequently asked questions
How do I use this calculator?
Enter requests allowed per window, window length, concurrent workers, mean request duration. The result updates automatically. Use Reset to restore the example values.
What method does it use?
steady throughput=min(quota/window, workers/duration).. Steady-state model, not a burst scheduler. Server variability, retries, distributed quotas and network limits are excluded.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
Are my inputs saved online?
No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
