Discount Calculation Tips

2

Stack Discounts

Apply percentage discount first, then dollar-off coupons for maximum savings.

How our discount calculator works

1

Enter original price

Type the original, pre-discount price. This is the list price or the price before any sale discount is applied.

2

Enter discount percentage

Type the discount as a percentage. Common retail discounts are 10%, 20%, 25%, 30%, or 50% off.

3

See final price and amount saved

Get the sale price, the dollar amount saved, and the effective percentage off (which is slightly different for stacked discounts).

Key things to know about our discount calculator:

  • Stacked discounts: 20% off then 10% off is not 30% off. Its 1 - (0.8 x 0.9) = 0.28, or 28% off. Use the discount calculator to verify chain discounts.
  • Comparing deals: BOGO 50% off vs $5 off $25: BOGO = 12.5% off, $5 off = 20% off. Always compare effective percentages, not advertised percentages.
  • Tax on discounted price: Sales tax is usually applied to the discounted price, not the original. The final total = (price x (1-discount)) x (1+tax).

A discount calculator is a free tool that finds the final price after a percentage discount and the dollar amount saved. Our discount calculator supports stacked discounts (e.g. 20% off then 10% off), sale prices, and tax addition. The discount calculator is useful for shopping sales, retail comparisons, and business pricing.

How it works

How to calculate a sale price and total savings

Our discount calculator lets you find the final price after a percentage discount, with optional stackable codes, in three steps.

  1. 1

    Enter the original price

    Type the pre-discount price shown on the tag or product page. This is the base the percentage is applied to.

  2. 2

    Enter the discount percentage

    Type the discount percent (e.g. 25 for 25% off). Add a second percentage if you are stacking multiple codes or sale prices - the calculator applies them sequentially.

  3. 3

    Read the result

    The result shows the sale price, the amount saved, and the total percent off the original. Stacked discounts show each layer separately for transparency.
