How to Use AI Cost Estimator

  1. 1

    Select your AI models

    Choose models you're using: GPT, Claude, Gemini, Llama, etc. The tool displays current pricing per 1M input and output tokens. Add multiple models if you're comparing or using a mix.

  2. 2

    Estimate token counts

    Input your expected monthly usage: number of requests, average input tokens (rule of thumb: 1 token ≈ 4 characters), and average output tokens. Or paste a sample prompt to auto-calculate token count.

  3. 3

    Factor in batching and caching

    Some models offer cheaper batch processing or prompt caching. Account for these if applicable. Prompt caching (e.g., Claude) reduces per-token costs for repeated inputs.

  4. 4

    Calculate total and per-request costs

    The tool shows monthly cost, per-request cost, and cost per feature/endpoint. Compare pricing across models to choose the best fit for your workload and budget.

Frequently Asked Questions

What is AI Cost Estimator?
AI Cost Estimator helps you estimate total AI API costs for real-world workloads. It calculates monthly and yearly expenses across all major providers based on your expected usage patterns.
How do I use AI Cost Estimator?
Define your workload by entering expected request volume, average input/output token counts, and select the AI models you want to compare. The tool calculates projected costs across providers instantly.
Is AI Cost Estimator free?
Yes. This tool is free to use with immediate access—no account required.
Does AI Cost Estimator store or send my data?
No. All processing happens entirely in your browser. Your workload data never leaves your device — nothing is sent to any server.
How accurate are the cost estimates?
Cost estimates use current published API pricing from each provider. Actual costs may vary based on factors like caching, batching discounts, and token count variations, but the estimates give you a reliable baseline for budgeting.
