How to Use the Discount Calculator
Our discount calculator is designed to help you shop smarter. Whether you're looking at a simple "20% off" tag or a complex "Buy 2 Get 1 Free" deal, you can find the true value of the offer in seconds.
Stacked Discounts: If a store offers "20% off everything" plus an "extra 10% off for members," these are usually stacked. This means the 10% is taken off the already discounted price, not the original price.
What is this Calculator Good For?
- Holiday Shopping: Calculate Black Friday and Cyber Monday deals instantly.
- Comparing Deals: Determine if "Buy 2 Get 1 Free" is better than "30% off everything."

Important Considerations
- Tax Calculation: Sales tax is usually calculated on the discounted price, but this can vary by region.
- Exclusions: Many discounts exclude certain brands or clearance items.
- Rounding: Stores may round prices differently (e.g., always rounding up to the nearest cent).
Discount Formulas
Final Price = Original Price × (1 - Discount Rate)
Stacked Discounts:
Final Price = Original Price × (1 - Discount 1) × (1 - Discount 2)
Buy X Get Y (at Z% discount):
Total Cost = (X × Price) + (Y × Price × (1 - Z))
Frequently Asked Questions
A stacked discount is when multiple discounts are applied one after another. For example, if you have a 20% discount and a 10% coupon, the 10% is applied to the price after the 20% has been taken off.
Yes, if you buy exactly two items, the effective discount is 50%. However, if you only need one item, 50% off a single item is often a better deal than being forced to buy two.
To find the savings, multiply the original price by the discount percentage (e.g., $100 x 0.20 = $20 savings). Subtract that from the original price to get the final price ($100 - $20 = $80).
