Discount Calculator
This discount calculator helps you calculate the final price after a discount, coupon, quantity, and estimated sales tax. It is useful for US shoppers who want to quickly understand the real checkout price before buying online or in-store.
You can use this tool as a percentage off calculator, sale price calculator, coupon discount calculator, price after discount calculator, final price calculator, and money saving calculator. It also includes a reverse discount calculator and price comparison calculator to help you compare two shopping deals.
How to Use the Discount Calculator

- Add quantity if you are buying more than one item.
- Add sales tax if needed.
- Add an extra coupon discount if available.
- Click calculate.
- Review the final price, sales tax amount, total savings, and effective discount percentage.
Discount Formula
The basic discount formula is simple:
Discount Amount = Original Price × Discount Percentage / 100
Final Price = Original Price – Discount Amount
For example, if an item costs $100 and has a 20% discount, the discount amount is $20 and the sale price is $80 before tax. If sales tax applies, the tax is usually calculated after the discount is applied.
Why Sales Tax Matters in the United States
In many US stores, product prices are shown before sales tax. That means the final checkout price may be higher than the sale price shown on the tag or website. Sales tax can depend on your state, city, or county, so this sales tax discount calculator helps estimate the real amount you may pay.
Coupon and Extra Discount Calculation
When a store offers an extra coupon or promo code, the second discount usually applies after the first discount, not on the original price.
Example: A $100 item with 20% off becomes $80. An extra 10% coupon applies to $80, making the final pre-tax price $72. This is why two discounts are not usually added together directly.
Reverse Discount Calculator
The reverse discount calculator helps you calculate the original price if you know the final sale price and discount percentage. This is useful when a store shows only the discounted price and you want to estimate the price before the sale.
Price Comparison Calculator
The price comparison calculator helps you compare two offers and find which deal is better. You can enter the original price, discount percentage, and optional sales tax for Offer A and Offer B. The tool then shows the final price of each offer and the difference amount.

| Original Price | Discount | Final Price Before Tax |
|---|---|---|
| $100 | 10% off | $90 |
