Formula
- Request cost = (input tokens × input rate + output tokens × output rate) ÷ 1,000,000
- Monthly cost = request cost × requests per day × 30
Methodology
Pricing is quoted per million tokens and split into input (what you send, including the system prompt and any retrieved context) and output (what the model writes back). The two rates are different, and output is usually the more expensive of the pair.
The calculator multiplies your token counts by the selected rate, then scales the per-request cost by your daily volume to a monthly and annual figure. A 30-day month and a 365-day year are used so results stay comparable between tools.
Provider prices change, so every model list includes a custom option. Enter the exact rates from your provider's pricing page for a number you can put in a budget. Model availability, pricing and specifications may change. Verify pricing directly with the provider before making business decisions.
Example: document analysis on Claude Sonnet
- A document analyser sends 8,000 input tokens and produces 1,200 output tokens per run, 200 runs a day, on Sonnet ($3 / $15 per million).
- Input: 8,000 ÷ 1,000,000 × $3 = $0.024. Output: 1,200 ÷ 1,000,000 × $15 = $0.018.
- Total $0.042 per run, $8.40 a day, about $252 a month.
Frequently asked questions
Which Claude model should I budget for?
Start with the mid tier for quality-sensitive work and the small tier for classification, extraction and routing. Opus is worth its premium only where the reasoning quality visibly changes the outcome.
Does a long context window cost more?
Only through the tokens you actually send. A large window lets you paste more, and every token you paste is billed as input, so long documents dominate the bill quickly.
Can prompt caching reduce the cost?
Yes. When the provider supports caching a stable system prompt or document, repeated reads of the cached portion are billed at a large discount. Enter your effective blended rate in the custom fields to model it.
Are these prices always up to date?
The presets reflect widely published list prices and are reviewed periodically, but providers adjust them and offer discounts for batch processing, cached input and committed spend. Model availability, pricing and specifications may change. Verify pricing directly with the provider before making business decisions.
What happens when a provider launches a new model?
Model names and rates live in one central configuration, so a new model appears in every relevant dropdown as soon as it is added. Page URLs stay provider-based rather than version-based, so no link ever goes stale when a model generation changes.
Does the calculator send my data anywhere?
No. Every calculation runs in your browser, so nothing you type is uploaded, stored or logged.
