How discounts work

A percentage discount takes a share of the price; a fixed discount takes a set amount. When several discounts are offered, each one usually applies to the price left after the previous one, which is why stacked discounts are worth less than their sum.

Formulas

  • Saving = price × discount ÷ 100
  • Sale price = price × (1 − discount ÷ 100)
  • Combined discount for two percentages = 1 − (1 − d₁) × (1 − d₂)

Frequently asked questions

How do I calculate a percentage discount?

Multiply the price by the discount percentage and divide by 100 to get the saving, then subtract it. 30% off 80 saves 24, so you pay 56.

Do two discounts add up?

No. A second discount applies to the already-reduced price. 20% off and then a further 10% off is 28% off in total, not 30%. The calculator shows the true combined discount.

How do I find the original price from a sale price?

Divide the sale price by 1 minus the discount. If something costs 60 after 25% off, the original price was 60 ÷ 0.75 = 80.

Can I use it for business discounts on invoices?

Yes. Work out the discounted price here, or apply line and invoice discounts directly in the free invoice generator.
