Enter token counts from your own request receipt and your own downstream input price. This calculator shows only arithmetic derived from those inputs; it does not predict a product outcome.
Illustrated request path
Request-level token arithmetic.
This page does not run a Zerix request.
It calculates the token and cost difference you enter from a request receipt or another source you choose.
Calculator inputs
Enter values you know. These controls never call Zerix, a provider, billing, or signup; they only run deterministic browser math.
If this is greater than input tokens, the calculator uses input tokens so saved tokens cannot be negative.

This is cost saved per request multiplied by the monthly request total you entered. It is not a forecast or a product receipt.
This calculator does not measure compression, quality, or latency.

Transparent math
tokens saved = input tokens - presented tokens.
cost saved = tokens saved / 1,000,000 x your downstream input price.
monthly saved = cost saved per request x monthly request total.
How to use this calculator
Enter token counts from a request receipt and the downstream input price you pay. The output is only the arithmetic on those values.
This page makes no network request. Use the signed-in dashboard when you want a live request receipt.
Every output on this page is arithmetic from the values you enter: input tokens, presented tokens, downstream input price, and monthly request total. This page does not make a product-performance claim.
