A few common questions
Does this calculator include tax or shipping?
No. It applies only the discount you enter to the original price. Tax, shipping, fees, exclusions, and store-specific rounding may change the amount you actually pay.
Can I use any currency?
Yes. The calculator does not convert currencies, so the result uses the same currency as your input. It displays up to six decimal places; round the final amount to the precision used by your currency.
How do I calculate two discounts in a row?
Apply the first discount, then use the discounted price as the original price for the second calculation. For 20% off 100 followed by another 10% off, the price becomes 80, then 72. The total discount is 28%.
How can I find the percentage discount from two prices?
Subtract the sale price from the original price, divide by the original price, and multiply by 100. If the original is 80 and the sale price is 60, the discount is (80 − 60) ÷ 80 × 100 = 25%.
Can I enter a discount over 100%?
This calculator accepts discounts from 0% to 100%. A 0% discount leaves the price unchanged, while a 100% discount makes the sale price zero. Original prices must be non-negative.
