Token Cost / ROI Calculator

Turn a model's per-token price and your usage into a monthly bill — and, if you know what the work replaced, into a rough return on investment.

Estimate what an LLM integration actually costs per month — and whether the time saved is worth more than the token costs.

What is calculated

Enter the monthly input/output token volume and the price per 1 million tokens of your provider. The calculator multiplies this to determine monthly and annual costs. If you additionally roughly estimate how many hours the automation replaces per month and what that time is worth, a simple ROI line is added — net value per month and a return multiplier.

This is intentionally imprecise: prompt caching, batch discounts, retries due to rate limits, and tiered pricing are not included. The value is an order of magnitude, not an exact calculation.
