# AI Cost Calculator

> Estimate AI cost per blog post, website page, documentation article, PRD, or shipped feature without starting from tokens.

## What This Calculator Does

This page converts real deliverables into estimated token usage, then compares monthly costs across major AI models.

Use cases include:

- Blog posts and SEO articles
- Website pages and landing pages
- Help-center and documentation articles
- PRDs and product specs
- AI-assisted feature shipping

## How The Estimate Works

A practical planning rule is that one English word is about 1.3 tokens.

LLM API cost = (input tokens × input price) + (output tokens × output price), multiplied by number of requests.

For content workflows, monthly output tokens are estimated from words per asset times revision passes. Monthly input tokens are estimated from brief words, context words, and revision instructions.

For feature workflows, the calculator estimates how many AI sessions each feature needs and how many prompt/response words are exchanged in each session.

## Example Monthly Cost Estimates

For 100 requests/day with 1,000 input + 500 output tokens per request:
