The AI API Cost Calculator helps developers, product managers, and startups estimate what they will actually spend when calling large language model APIs across the major providers. You plug in your expected token volumes and the tool breaks down costs side by side for Claude, GPT, Gemini, and DeepSeek, so you can budget accurately before you build. It is built for anyone who bills by the token and needs real numbers, not guesses.
Reach for this tool when you are evaluating which AI provider fits your budget, scoping a new product feature, or auditing monthly API spend. It is especially useful when you are choosing between providers and need an apples-to-apples comparison without manually reading through four different pricing pages.
How to use it
- Select the AI providers you want to compare from the available options.
- Enter your estimated monthly input token volume for your use case.
- Enter your estimated monthly output token volume separately.
- Choose the specific model tier for each provider, such as standard or premium.
- Review the cost breakdown table showing monthly estimates per provider.
- Adjust token volumes to run what-if scenarios before committing to a provider.
Pro tips
- Output tokens typically cost two to four times more than input tokens, so even modest response lengths can dominate your total bill.
- DeepSeek pricing often looks dramatically cheaper at low volumes but model latency and rate limits may offset savings in production workloads.
