Calculate the final price on a sale, handling both single and stacked discounts instantly. Many retailers layer discounts - a "20% off" sale followed by "extra 15% off sale items" - but they don't add up to 35% off. This tool works out the true price you pay and the actual discount percentage applied.
$80 at 25% off costs $60 (you save $20).
$100 with a 25% discount, then an additional 25% off, costs $56.25 - not $50. The effective discount is 43.75%, not 50%.
How do I calculate a discount?
Multiply the original price by (1 − discount fraction). For 25% off $80: $80 × 0.75 = $60.
Do two discounts add up?
No - they stack multiplicatively. A 25% discount followed by another 25% discount is not 50% off. After the first discount you pay 75%; the second discount applies to that reduced amount: $100 × 0.75 × 0.75 = $56.25, which is 43.75% off the original.
How do I find the original price from a sale price?
Divide the sale price by (1 − discount fraction). For example, if you paid $60 after a 25% discount: original = $60 ÷ 0.75 = $80.
