Discount Calculator

Yes. This is a free online discount calculator for percent-off sales, coupon discounts, stacked promotions, and BOGO offers. Enter prices and discount values to get final price, total savings, and effective discount percentage instantly.

Use this formula: Final Price = Original Price x (1 - Discount%/100). For a coupon plus an existing sale, apply discounts one after another. Example: $100 with 20% sale and 10% coupon becomes $100 x 0.80 x 0.90 = $72.

To calculate a percentage discount, multiply the original price by the discount percentage, then divide by 100. For example, 25% off a $80 item: $80 × 25 / 100 = $20 discount, so the sale price is $80 - $20 = $60. You can also multiply the original price by (1 - discount/100) directly: $80 × 0.75 = $60. Our calculator handles this instantly for any price and discount combination.

A multi-tier discount (also called a stacked or successive discount) applies multiple percentage discounts one after another. For example, a 20% off sale plus an extra 10% off coupon does not equal 30% off. Instead, the first 20% is applied to the original price, then the second 10% is applied to the already-reduced price. On a $100 item: $100 × 0.80 = $80, then $80 × 0.90 = $72. The combined effective discount is 28%, not 30%.

BOGO deals offer free or discounted items when you purchase a qualifying quantity. 'Buy One Get One Free' (BOGO 50% off total) means you pay for one item and get a second free — effectively 50% off per item when buying two. Variations include 'Buy 2 Get 1 Free' (33% off per item across three) or 'Buy One Get One 50% Off' (25% off per item across two). Our calculator supports custom Buy-N-Get-M configurations so you can see exact savings.

To compare discounts, calculate the final price for each offer on the same item or total purchase. A flat 30% off may save more than 20% + 15% stacked (which is only 32% combined). For BOGO deals, divide total cost by total items to find the per-unit price. Our discount calculator lets you compute each type side by side so you can choose the best deal at a glance.

Whether discounts can be stacked depends on the retailer's policy. Some stores allow combining a sale price with a coupon code, loyalty discount, or credit card cashback. When stacking is allowed, each successive discount is applied to the already-reduced price, not the original price. This means the order of discounts does not affect the final price mathematically, but the total savings will always be less than the sum of individual percentages.

To find the original price when you know the sale price and discount percentage, divide the sale price by (1 - discount/100). For example, if an item is on sale for $60 after a 25% discount: $60 / (1 - 0.25) = $60 / 0.75 = $80 original price. This reverse calculation is useful for verifying advertised discounts or determining markup before a sale.

Yes. You can use the direct percentage mode for coupon discounts, stacked mode for sale + coupon deals, and BOGO mode for bundle promotions. This lets you compare multiple deal types and pick the best final price.

Yes. Enter the product prices and apply the advertised Cyber Monday sale, then add any extra coupon as a second discount. The calculator shows final price, total savings, and effective discount percentage.

Enter the shelf price and discount percent to get the discount price immediately. If the offer is more complex, such as stacked percentages or BOGO, switch modes and compare results before buying.
