How to Calculate Discounts
A discount calculator helps shoppers, businesses, and retailers instantly determine the final price after any type of markdown. Whether you're comparing sale prices, figuring out coupon savings, or building a promotional pricing strategy, our calculator handles every scenario.
Discount Formulas
Percent Off: Final Price = Original × (1 − Discount% / 100)
Fixed Amount: Final Price = Original − Discount Amount
Reverse: Original = Sale Price / (1 − Discount% / 100)
Stacked: Apply each discount sequentially to running price

Cart Builder
Different items may have different discount rates. Use the cart builder to find true total savings.
Frequently Asked Questions
Are stacked discounts the same as adding percentages?
No — stacked discounts are multiplicative, not additive. A 20% discount followed by another 10% discount gives a total of 28% off (not 30%). Each discount applies to the already-reduced price. Our Stacked mode shows each step clearly.
How do I calculate the original price from a sale price?
Use the Reverse mode: Original Price = Sale Price ÷ (1 − Discount% ÷ 100). For example, if you paid $63 after a 30% discount, the original was $63 ÷ 0.70 = $90.
What is the effective discount on a Buy 2 Get 1 Free deal?
On a Buy 2 Get 1 Free deal, you pay for 2 items but get 3 — so you're effectively getting 33.3% off across all 3 items. Our BOGO mode calculates the exact effective discount percentage and total savings.
How do I calculate a percentage discount manually?
Multiply the original price by the discount percentage and divide by 100 to get the discount amount. Then subtract from the original. Example: 25% off $80 = $80 × 25 ÷ 100 = $20 saved → Final price $60.
