Click Calculate to see the final price, savings, and an optional stacked second discount.
The Discount Calculator lets you instantly find the final price and total savings after applying a percentage or flat discount. It also supports stacked discounts — common in e-commerce promotions where a site-wide sale stacks on top of a coupon code.
Multiply the original price by the discount percentage and divide by 100 to get the discount amount, then subtract from the original price. For example, 20% off $80 = $80 × 0.20 = $16 saved, final price = $64. This tool does it instantly.
A stacked discount applies a second discount on top of the already-discounted price. For example, 20% off then an extra 10% off does NOT equal 30% off — it equals 28% off. The first discount brings $100 to $80, then 10% off $80 = $72 final.
A flat (fixed) discount subtracts a fixed amount from the price regardless of the original price (e.g. "$10 off"). A percentage discount scales with the price (e.g. "20% off"). Use the toggle to switch between modes.
Yes — use the Currency Symbol selector to switch to €, £, ¥, ₫, ₩, ₹, C$, A$, or no symbol at all. The tool performs the same math regardless of currency; only the display label changes.

For percentage discounts the maximum meaningful input is 100% (free). For flat discounts, if the discount amount exceeds the original price the tool will warn you, since you can't pay a negative price in normal scenarios.
Whether you're shopping during a Black Friday sale, planning e-commerce pricing, or evaluating a coupon deal, knowing the exact final price after a discount is essential. Our free Discount Calculator handles both percentage-based and flat-amount discounts, with optional stacked discount support so you always know exactly what you'll pay — and what you'll save.

The formula for a percentage discount is straightforward:
Example: You find a jacket originally priced at $120 marked down 35%. The discount amount is $120 × 0.35 = $42. The final price is $120 − $42 = $78. You save $42, or 35% of the original price.
A flat discount subtracts a fixed dollar amount from the original price:
Example: A $250 appliance has a "$40 off" coupon. Final price = $250 − $40 = $210. Your savings percentage is 40 ÷ 250 × 100 = 16%.
Stacked discounts are common in online retail — a site-wide sale might offer 20% off, and you apply a coupon code for an additional 10% off. The key insight: the second discount applies to the already-reduced price, not the original price. This means stacked discounts do NOT simply add together.
Example: $100 item, 20% off then 10% off:
Our calculator handles stacked discounts automatically — enter both discount values and it shows you the breakdown for each step and the combined effective discount rate.
Online Shopping: Before adding to cart, quickly verify what a "30% off" badge means in actual dollars. Paste the original price and discount, and you'll know in seconds whether it's a deal worth taking.
E-commerce Pricing: Merchants and product managers use discount calculators to preview how sale prices will appear to customers, ensuring margins are maintained while promotions are attractive.
Coupon Stacking: Many retailers allow combining store promotions with manufacturer coupons. Knowing the effective combined discount helps you evaluate whether it's worth the effort of applying multiple codes.
Wholesale & Bulk Buying: Suppliers often quote tiered discounts — "5% off orders over $500, plus 3% for annual contracts." The stacked discount feature calculates the net price after both apply.
Finance & Budgeting: Understanding the true cost of items after discounts helps with budget planning, especially for large purchases like electronics, furniture, or travel bookings.
Knowing how discounts work mathematically gives you an edge as a shopper or seller. A few practical tips:
While mental math or a basic calculator can handle simple percentage discounts, our tool offers several advantages: instant results, stacked discount support, a visual savings bar showing what portion of the price you're paying versus saving, and a copy-to-clipboard summary perfect for sharing deal breakdowns with friends or documenting pricing decisions. It's also completely free, requires no login, and runs entirely in your browser — your pricing data never leaves your device.
