Multi-model Cost Comparison
Compare API costs across multiple LLM providers and models side by side.
About Multi-model Cost Comparison
Comparing LLM costs across providers helps choose the most cost-effective model for your use case. Total cost depends on input/output token pricing multiplied by volume. Cheaper models may suffice for simple tasks while complex reasoning may require premium models.
Formula
Daily Cost
daily = requests × ((input_tokens/1M × input_price) + (output_tokens/1M × output_price))
- requests
- Number of API requests per day

Assumptions and limits
- The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
Frequently Asked Questions
Should I always pick the cheapest model?
No — cheaper models may produce lower quality outputs requiring more retries or human correction. Consider quality-adjusted cost: cheaper per-token but needing 3x tokens for the same result is actually more expensive.
Do prices change frequently?
Yes — LLM pricing is competitive and drops frequently. Check provider pricing pages for current rates. This calculator uses representative pricing for comparison purposes.
