A discount calculator online tells you the final price after a percentage reduction and how much you save - helpful for shopping, sales, pricing strategy, and financial decisions.
What is a Discount Calculation?
A discount is a reduction in the original price of a product or service, expressed as a percentage. The final price after a discount is:
Final Price = Original Price × (1 - Discount% / 100) Savings = Original Price - Final Price
For example, a $150 jacket at 30% off:
- Final Price = $150 × (1 - 0.30) = $150 × 0.70 = $105
- Savings = $150 - $105 = $45

Common Scenarios
Retail shopping - Check whether a "50% off" sale price makes sense before you buy.
Black Friday / Cyber Monday - Quickly evaluate deals when multiple items are discounted at different rates.
Coupon codes - Calculate the real price after applying a percentage coupon.
Business pricing - Price products after supplier discounts to ensure margin targets are met.
Wholesale purchasing - Evaluate volume discounts: is buying 500 units at 15% off better than 1,000 at 20% off?
Stacking Discounts
When two discounts are applied sequentially, they do not simply add up. A 20% discount followed by an additional 10% discount gives:
100% → after 20% off = 80% → after 10% off = 72%
That is a combined discount of 28%, not 30%. Use the calculator twice in sequence to handle stacked discounts accurately.
Original Price from Final Price
If you know the final price and the discount percentage but want to find the original price:
Original Price = Final Price / (1 - Discount% / 100)
For example, if a sale item costs $84 after a 30% discount: Original Price = $84 / 0.70 = $120
FAQ
What is the difference between a discount and a markdown? Both reduce the price, but "discount" typically refers to a percentage off applied at checkout, while "markdown" usually refers to a permanent price reduction on the shelf.
How do I calculate a 10% discount in my head? Move the decimal point one place to the left. 10% of $47.50 = $4.75. Subtract from the original: $47.50 - $4.75 = $42.75.
Can I calculate the discount percentage from the original and final prices? Yes: Discount% = (Original - Final) / Original × 100. Use the Percentage Calculator in Mode 3 for this.
What if the discount shows as a flat amount instead of a percentage? Divide the flat discount by the original price and multiply by 100 to get the percentage, then use this calculator.
