Free OpenAI API Cost Calculator for SaaS Builders

Free OpenAI API Cost Calculator for SaaS Builders

When I first added AI features to my SaaS, I had no idea how to price them. The bills kept coming, and I had no framework for passing those costs to customers.

So I built a calculator.

The Problem with AI Pricing

Most developers make one of two mistakes:

  1. Underpricing: Absorbing AI costs that eat into margins
  2. Overpricing: Scaring away customers with opaque pricing

Neither leads to sustainable business.

The Calculator

This free tool helps you estimate AI costs for common SaaS scenarios:

  • Chatbot with conversation history
  • Document summarization at scale
  • Content generation per user
  • Image generation workflows

How It Works

The calculator uses three inputs:

  1. Token count per request (prompt + completion)
  2. Requests per user per month
  3. Model pricing (OpenAI's current rates)

Output: Monthly cost per user, with margin built in.

My $10 Offer

If you're building AI features and want a second opinion on your cost structure, I offer:

$10 AI Cost Architecture Review

  • Review your current API usage patterns
  • Identify waste or optimization opportunities
  • Provide a pricing recommendation

PayPal: https://paypal.me/cheapuno

This takes 15-20 minutes and usually saves more than $10/month in API costs.

Why This Is Free

The calculator is free because most people who need it won't act on it. But the 5% who do might need the full consultation. That's how I earn.
