Calculate sale price
Find the original price
How Is a Discount Calculated?
Sale price = original price × (1 − discount ÷ 100). A 25% discount on 80 gives 80 × 0.75 = 60, saving 20. The reverse calculator answers "what was the original price?": original = sale price ÷ (1 − discount ÷ 100) — useful for checking whether a "was/now" label is honest.
Both calculators update as you type; you can also stack a second discount (e.g. an extra 10% at checkout) to see the true combined percentage, which is always less than their sum.
Frequently Asked Questions
Do two stacked discounts add up?
No. 20% + 10% applied in sequence equals 28%, not 30%: the second discount applies to the already-reduced price (0.8 × 0.9 = 0.72).
How do I find the original price from the sale price?
Divide the sale price by (1 − discount rate). An item sold at 60 with 25% off originally cost 60 ÷ 0.75 = 80.
How much do I save in money terms?
Multiply the original price by the discount rate: 25% of 80 is 20. The tool shows the saved amount alongside the final price.
