Frequently Asked Questions
How do I calculate percentage off?
Multiply the original price by (100 - discount percentage) / 100. For example, 20% off $100 = $100 × 0.80 = $80.
How do stacked discounts work?
Stacked discounts are applied sequentially. For example, 20% off then 10% off $100: first $100×0.80=$80, then $80×0.90=$72. The total effective discount is 28%, not 30%.
What's the difference between stacked and combined discounts?
Stacked (sequential): each discount applies to the already-discounted price. Combined: all percentages added together then applied once. Stacked gives a smaller total discount.
Can I add tax to the final price?
Yes, enter the tax rate in the tax field and it will be applied to the discounted price to show the final amount you'll pay.
How do I calculate the discount percentage from sale price?
Use the reverse calculator: enter the original price and sale price. The discount percentage is (original - sale) / original × 100.
Is this calculator free to use?
Yes, completely free with no sign-up required. It runs entirely in your browser.
Can I calculate fixed amount discounts?
Yes, switch the discount type from '%' to '$' to enter a fixed dollar amount off instead of a percentage.
Does this work for any currency?
Yes, it works with any currency. Simply enter the price in your preferred currency and the calculations remain the same.
