Updated AI Inference Cost Tool

Inference Cost Calculator

Estimate AI inference cost per request, per user session, per month or per GPU hour. Enter input and output tokens, batch usage or self-hosted GPU time to see total cost, effective price per 1K and per 1M tokens, and cost per request.

Input & Output Tokens Requests & Sessions Batch / Monthly Usage GPU-Based Inference

Calculate AI Inference API Cost

Use this Inference Cost Calculator to model cost from different angles: per-request usage, aggregate monthly tokens or GPU hours for self-hosted inference. Choose built-in OpenAI-style pricing or define your own custom provider and per-token rates for any model or platform.

Token-based pricing distinguishes between input tokens (prompt, context, tools) and output tokens (model responses). The calculator always converts your configuration into a consistent “USD per 1K” and “USD per 1M” view for simple comparison.

Use this tab to estimate cost for a typical request or user session, then scale it by the number of requests or sessions to find total cost and per-request averages.

If provided, the calculator will show average cost per request.

Batch mode is ideal for monthly cost projections or aggregate usage across an application, product feature or entire tenant base.

If provided, the calculator will show an effective cost per 1K and 1M tokens.

Use the GPU tab to estimate self-hosted inference cost when you rent or own GPUs directly and want to understand effective cost per token or per request from a hardware perspective.

Inference Cost Calculator Inputs

Inference Cost Calculator uses Pricing Mode, Model, Custom Provider / Model Name, Custom Pricing Unit, Input Price (USD).

Inference Cost Calculator Formula or Method

Inference Cost Calculator is better described by a rule sequence than by one universal algebraic equation. The tool validates the supplied values, normalizes the units or formats needed by the selected mode, applies the calculator-specific lookup, date, scoring, conversion, or conditional rules, and then formats the resulting output.
