Anthropic
Anthropic API Cost Calculator
Calculate your estimated Anthropic API costs based on requests, input tokens, and output tokens. Compare Claude model pricing and estimate your daily, monthly, and yearly API expenses.
Anthropic Models
Compare Claude model pricing and choose a model to calculate your expected Anthropic API costs.
How to Calculate Anthropic API Costs
Anthropic API costs depend on the Claude model you use and the amount of input and output tokens processed by your application.
To estimate your total spending, enter your expected number of daily requests together with the average number of input and output tokens per request.
Cost = (Input Tokens ÷ 1,000,000 × Input Price)
+ (Output Tokens ÷ 1,000,000 × Output Price)
What Affects Anthropic API Cost?
Number of Requests
The number of API requests your application sends directly affects your total Anthropic API spending. Higher request volume generally produces higher costs.
Input Tokens
Input tokens include prompts, instructions, conversation history, documents, and other context sent to the Claude model. Larger inputs increase the cost of each request.
Output Tokens
Output tokens are generated by Claude. Longer responses can increase the cost of an API request, especially when output pricing is higher than input pricing.
Model Selection
Claude models have different input and output prices. Comparing models using the same token volume can help you evaluate the trade-off between model capability and API cost.
Anthropic API Cost Examples
Your actual Anthropic API bill depends on usage. Common workloads include AI assistants, chat applications, content generation, automation tools, document processing, and SaaS products.
Small AI App
A small application with limited daily usage may generate relatively low API costs while testing an AI workflow.
SaaS Application
A growing SaaS product can generate thousands of API requests per day, making token efficiency and model selection increasingly important.
Production Workload
High-volume applications should estimate request volume and average token usage before setting an Anthropic API budget.
Plan Your Anthropic API Budget
If you already have a monthly spending limit, you can estimate how many Anthropic API requests your budget could support based on your expected input and output token usage.
