Discount Calculator

Our Discount Calculator is a fast and easy way to calculate the final price of an item after applying a discount and optional sales tax. Whether you're shopping at a sale or calculating bulk order prices, this tool provides instant results.

How to calculate discounts

1. Enter Original Price: Input the list price of the item before any discounts.
2. Set Discount %: Enter the discount percentage (e.g., 20 for 20% off).
3. Add Sales Tax (Optional): If you want to know the final price including tax, enter your local sales tax rate.
4. View Results: The calculator shows your total savings and the final amount you need to pay.

Discount Formulas

If you want to do the math yourself, here are the formulas we use:

• Savings Amount = Original Price × (Discount / 100)
• Price After Discount = Original Price - Savings Amount
• Tax Amount = Price After Discount × (Tax / 100)
• Final Price = Price After Discount + Tax Amount

Shopping Tips for Sales

• Check the MSRP: Sometimes stores raise the "Original Price" right before a sale to make the discount look bigger.
• Stacking Coupons: If you have multiple discounts, they are usually applied sequentially, not added together (e.g., 20% off plus 10% off is actually 28% off, not 30%).
• Compare Unit Prices: Don't let a big discount distract you from the unit price (price per ounce, liter, etc.).
