## Quick Answer

Back out the pre-tax price (subtotal) and the sales tax paid from a final transaction total. Simply input the total price and the sales tax rate.

## Definition

A reverse sales tax calculator is a mathematical utility that extracts the pre-tax subtotal and the exact sales tax amount from a tax-inclusive total price. By dividing the total price by 1 plus the sales tax rate, it reverses the compounding effect of the tax addition. It is commonly used by accountants, businesses, and consumers to reconcile invoices, file sales taxes, or verify receipts.

## How to Use

1. **Enter total price** — Input the final amount paid or invoiced, which already includes sales tax.
2. **Set sales tax rate** — Provide the percentage rate of the sales tax applied to the purchase.
3. **Review pre-tax subtotal** — See the separated pre-tax subtotal and the exact sales tax amount extracted.
