What is a discount rate?

A discount rate is the amount taken off an item's original (list) price, expressed as a percentage (%). For example, '30% off' means 30% is deducted from the list price and you pay only 70%.

Store sales are usually advertised as a percentage, but the money that actually leaves your wallet is the discount amount, so it helps to look at both. The same 50% off saves a very different amount on a $5 item versus a $500 one.

Enter the list price and the discount rate, and this calculator instantly shows your savings and the final price you pay, helping you judge how much cheaper something really is while shopping. It is handy for comparing discounts across products or previewing the real checkout price after a coupon.

Calculation formula

A discount is calculated in two steps.

  • Discount amount = Original price × Discount rate ÷ 100
  • Final price = Original price − Discount amount

For example, applying a 25% discount to an item priced at 80,000 gives a discount of 80,000 × 25 ÷ 100 = 20,000, and a final price of 80,000 − 20,000 = 60,000. Here the original price is the pre-discount list price, the discount rate is the percentage taken off (%), and the discount amount is rounded to the nearest whole unit.

Frequently Asked Questions

How do I calculate a discount rate?
Discount amount = Original price × Discount rate (%) ÷ 100. The final price is the original price minus that discount amount. For example, a 30% discount on a 100,000 item gives a 30,000 discount and a final price of 70,000.
How do I find the discount rate when I know the discount amount?
Discount rate (%) = (Original price − Sale price) ÷ Original price × 100. For example, if 30,000 was knocked off 100,000, the discount rate is 30%. You can work out the effective discount just from the list price and the amount paid on the receipt.
How do stacked discounts work?
Stacked discounts are not added together; they are applied one after another. A 30% discount followed by an extra 10% is a 37% total discount, not 40% (1 − 0.7 × 0.9 = 0.37), because the second 10% applies to the remaining 70% after the first cut.
What is the difference between discount rate and discount amount?
The discount rate is a percentage (%), while the discount amount is the actual money taken off. For the same rate, a higher original price means a larger discount amount. A 50% discount saves 5,000 on a 10,000 item but 500,000 on a 1,000,000 item.
Can I calculate prices that include sales tax?
If the listed price already includes tax (e.g. 10%), the discount applies to the tax-inclusive price, so you can calculate it as-is with no extra adjustment. If the list price is the pre-tax (net) amount, add 10% to the discounted figure to get the final amount due.
What discount percentage is a 'buy 1 get 1' or 'buy 2 get 1' deal?
Buy 1 get 1 free gives an extra item for the price of two, which equals 50% off per item, while buy 2 get 1 free makes one of three free, an effect of about 33.3% off. But if you have to buy quantities you will not use, judge by your actual need rather than the unit price alone.
Is '70% of the list price' the same as a percentage 'off'?
No. 'Sold at 70% of the list price' means a 30% discount; that is, sale-price ratio + discount rate = 100%. If you see an ad that mislabels it as '30% sale price', always check whether you pay 30% or 70% of the list price.
Is a bigger discount rate always a better deal?
Because the discount rate is based on the list price, an inflated list price can make even a large discount not actually cheap. Comparing the final price against the usual market price is the key to a smart purchase, rather than the discount rate alone.
