Needlepath · AI Cost Calculator

What does a month of context actually cost you?

Your numbers, plain arithmetic, no signup. Set your traffic and your model's list prices, and see your AI bill itemized the way providers charge it: input tokens vs output tokens. Calculations run in your browser. No signup required.

Prices are whatever you type. This page never claims what any vendor charges you.

What-if: you move the slider, we do the arithmetic

Suppose some share of those input tokens is dead weight for a given call: stale history, distractor chunks, unused tool schemas. If of your input tokens didn't ship, the same month costs:

/mo

This is your arithmetic, not a Needlepath result. What your actual share is depends on your workload. Shadow mode measures that number on your own traffic.

See your own number before you spend anything. Shadow mode runs on one workflow: your traffic, your number, no commitment. The report: answer quality, tokens removed, cost saved.
