🏷️ Discount Calculator

Find sale price after a percent-off discount, original price before markdown, or savings amount on a retail tag.

Discount Math — Stacking, Markdown, and Reverse Price

BrainyCalculators editorial insight — unique to this tool

A 20% off plus additional 10% at Indian festive sales is 28% total, not 30% — discounts compound multiplicatively. Reverse calculation: if final price is ₹799 after 15% off, original = 799 ÷ 0.85. Retailers use psychological price points (₹999 vs ₹1,000) after discount application.

When to use this calculator

What is a Discount Calculator?

A discount calculator applies a percent markdown to a list price and shows final price and amount saved. It can reverse-solve original price from a discounted shelf tag.

Use this page for consumer sales and promotions. Markup starts from cost to set selling price upward; discount starts from list price downward.

Commission and tip calculators allocate portions of revenue or a bill rather than modeling shelf markdowns.

Discount Formulas

Sale Price = Original Price × (1 − Discount% / 100)

Original Price = Sale Price ÷ (1 − Discount% / 100)

Discount% = ((Original − Sale) ÷ Original) × 100

You Save = Original Price − Sale Price

These formulas work for any currency — the calculator is currency-neutral.

Frequently Asked Questions

How do I calculate a percentage discount?

Multiply the original price by the discount percentage divided by 100, then subtract from the original price. For example, 25% off $200 = $200 × 0.25 = $50 saved, so the sale price is $150.

How do I find the original price after a discount?

Divide the sale price by (1 − discount% / 100). If you paid $150 after a 25% discount, the original price was $150 ÷ 0.75 = $200.

What is the difference between discount and markdown?

Both reduce the selling price, but a discount is typically a temporary promotional reduction, while a markdown is a permanent reduction in the listed retail price.

How do I calculate two successive discounts?

Apply each discount sequentially. A 20% then 10% discount is not 30% — it is: $100 × 0.80 × 0.90 = $72, which is a 28% total discount.

Is a 50% discount the same as half price?

Yes. A 50% discount means the sale price is exactly half the original price. You save the same amount as you pay.

When Discounts Work Well

✓ Clear percentage off is easy for consumers to evaluate
✓ Drives urgency and accelerates purchasing decisions
✓ Helps clear excess inventory efficiently
✓ Rewards loyal customers or large-volume buyers

Discount Pitfalls

✗ Frequent deep discounts erode perceived value
✗ Inflation of "original" prices makes the deal appear better than it is
✗ Successive discounts are not additive — a 20%+10% is not 30%
✗ Can trigger a race to the bottom in competitive markets

Common Discount Mistakes

Adding Sequential Discounts

Two discounts of 20% and 10% are NOT 30% off. Apply each in sequence: $100 × 0.80 × 0.90 = $72 (28% total).

Confusing Discount and Markup

A 50% discount means the sale price is half the original. A 50% markup means the price is 1.5× the cost. These are different operations with different base values.

Ignoring Hidden Fees

A discounted item may still have shipping, handling, or assembly fees. Always calculate the all-in cost before comparing deals.

Comparing Percentages Across Different Base Prices

30% off a $200 item ($60 savings) beats 50% off a $100 item ($50 savings). Always compare dollar savings, not just percentages.

Forgetting the Margin Impact

A 20% discount on a product with a 25% margin can turn profit into loss. Sellers must calculate whether the discount still leaves a positive margin.
