# Pricing Math: Fee-Inclusive Price Calculator

> Pricing Math: Fee-Inclusive Price Calculator is a paid API for AI agents from pricing-math.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-30).

Calculates the gross price to charge customers so that after deducting a percentage fee and a fixed fee, you retain a specified net amount.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability pricing-math-fee-inclusive-price-calculator-a93df138
```

Example prompt: What price do I need to charge so I net $45 after a 2.9% payment processing fee plus a $0.30 fixed fee per transaction?

## When to prefer this

Use this endpoint when you know your desired net proceeds and the exact fee structure (percentage + optional fixed fee) and need to compute the correct gross price to charge — it is purpose-built for this algebraic inversion. Prefer it over general markup/margin calculators when fees are expressed as a percentage-plus-fixed structure (e.g. payment processors, marketplaces). It is distinct from the markup-to-margin endpoint (which works from cost) and the tax splitter (which handles VAT/sales tax).

## Known failure modes

- feePct is 100 or above — mathematically undefined, likely returns an error
- targetNet is zero or negative — no meaningful result
- Missing required query params (targetNet or feePct) — 400-level error
- feePct is negative — may return unexpected results or error
- Very large fixedFee relative to targetNet — may produce implausibly large required price

## How this service works

Price to charge so you net a target after a percentage fee plus a fixed fee, with fees you supply. No fee table built in.

## Output

Returns the exact required gross price (requiredPrice), the price rounded up to the nearest cent (requiredPriceRoundedUpToCent), a naive markup price for comparison, the net you'd actually receive at the rounded price, the total fee at the required price, and the fee as a share of the price in percent.
