How Discount Calculations Work

Applying a Discount

Take a known percentage off the original price to find what the customer actually pays.

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

Finding the Discount %

Work backward from the sale price to see exactly what percentage was taken off.

Discount% = (Original − Final) / Original × 100

How to use the Discount & Markdown Calculator

  1. Choose the mode: apply a known discount to a price, or work out what percentage a sale price represents.
  2. Enter the original price and either the discount percentage or the sale price.
  3. Read the sale price, the amount saved and the discount percentage, and copy the breakdown for a price tag or a quote.

When to use it

Retailers marking down end-of-season stock, wholesalers quoting volume discounts, and anyone checking whether a supplier's "30% off" really is 30% all need the same three numbers. The reverse mode is the useful one at the till or in negotiations: when someone offers a price, it tells you instantly what discount that is, so you can compare offers on the same basis.

The formulas

In discount mode: sale price = original × (1 − discount ÷ 100), and the amount saved = original × discount ÷ 100. In reverse mode the calculator takes the original and the sale price and returns discount = (original − sale) ÷ original × 100, with the amount saved as the difference. Both modes show the same three figures, so you can switch between them to check a price tag against a promised percentage.

Worked example

A jacket has an original price of $80. At 25% off the sale price is 80 × 0.75 = $60.00 and the customer saves $20.00. A competitor lists the same jacket at $56: reverse mode with 80 and 56 shows that is a 30% discount, so "25% off" is the weaker offer by $4. Now stack: 20% off, then a further 10% at the till. The second 10% applies to $64, not $80, so the final price is $57.60, a combined discount of 28%, not 30%. Run the two steps one after another in the calculator to see it.

Common mistakes

When this calculator is the wrong tool

It handles one discount on one price. For a full grid of sale prices at every percentage from 10% to 90%, see the discount table and the per-percentage pages under pricing. For volume pricing, where the unit price steps down at quantity breaks, you need a price list rather than a percentage. And a discount that has to leave a fixed profit behind is a margin problem, not a discount problem.

Good to know

Two successive discounts do not add up: 20% then 10% off is 28% off, not 30%. Run each step separately if you stack offers. A markdown should be checked against your margin as well; the Profit Margin Calculator linked below shows whether the discounted price still covers your cost.
