The Missing Piece of Your Receipt
Whether you are a shopper trying to budget or a business owner creating an invoice, our AI Sales Tax Calculator solves the math instantly.
3 Ways to Use It:
- Add Tax: Price + Rate = Final Total.
- Remove Tax: Final Total - Rate = Pre-Tax Price.
- Find the Rate: "I paid $107 for a $100 item. What was the tax?" (Answer: 7%)
Mastering the Price Tag
In the United States, the price you see on the shelf is rarely the price you pay at the register. Sales tax is added at the point of purchase, and the rate varies wildly from state to state.
Our AI Sales Tax Calculator is a versatile tool designed to work forward and backward. It helps you anticipate the final bill or "back out" the tax from a total receipt for expense reporting.
How to "Reverse" Sales Tax
Sometimes you have the final receipt (e.g., $108.25) and need to know the original price of the item before tax. This is crucial for business accounting.
The Reverse Formula
Pre-Tax Price = Final Price / (1 + Tax Rate)
Example: If you paid $107 total and the tax rate is 7% (0.07):
$107 / 1.07 = $100.00 (Pre-Tax Price)
