FAQ

How do I calculate a 20% discount? โ–ผ
To calculate a 20% discount, multiply the original price by 0.20 to get the savings. Then subtract that amount from the original price. Or just use our calculator!
What is "30% off" of $100? โ–ผ
30% of $100 is $30. So, $100 minus $30 equals a final price of $70.
Can I calculate double discounts? โ–ผ
Yes. For "stacking" discounts (e.g., 20% off plus an extra 10% off), calculate the first discount, then use that new price as the original price for the second discount. Do not just add the percentages together (20+10=30% is incorrect).
Does this support tax calculation? โ–ผ
Yes. Click "Add Tax" below the discount field to enter your local tax rate. The tax will be calculated on the discounted price and added to the total.
Is "Buy 1 Get 1 Free" a 50% discount? โ–ผ
Technically, yes. If both items have the same price, getting two for the price of one is equivalent to a 50% discount on the total.
How are results rounded? โ–ผ
Results are rounded to two decimal places, which is standard for most currencies.
Why is tax calculated on the discounted price? โ–ผ
In most jurisdictions, sales tax is applied to the final transaction price (after discounts), not the original sticker price.
Is my data private? โ–ผ
Absolutely. All calculations happen right in your browser. No data is ever sent to our servers.
