Discount Calculator
Work out sale prices, savings and optional tax in one step.
What is the Discount Calculator?
This calculator finds the final price of an item after a percentage discount, how much money that discount saves you, and — if you add a tax rate — how much tax applies on top of the already-discounted price. Every field updates live as you type, so you can experiment with different discount levels instantly.
How to use it
- Enter the original price of the item.
- Enter the discount percentage being offered.
- Optionally enter a sales tax percentage if tax applies after the discount in your situation.
The math is straightforward: the amount saved is the original price multiplied by the discount percentage, and the discounted price is the original price minus that amount. When a tax rate is entered, it is calculated on the already-discounted price, which matches how most retail receipts apply tax after a coupon or sale discount rather than before it. This tool works with any currency since it only deals in plain numbers, making it useful when comparing sale prices while shopping, checking whether a "% off" deal is actually worth it, or double-checking a receipt.
