Question 1

How do I calculate a percentage discount?

Accepted Answer

To calculate a percentage discount, multiply the original price by the discount percentage and divide by 100. Then subtract that amount from the original price. For example, 20% off $80: $80 x 20/100 = $16 savings, so the sale price is $80 - $16 = $64. This calculator does the math instantly for any price and percentage.

Question 2

How do I find the original price from a sale price?

Accepted Answer

To find the original price when you know the sale price and discount percentage, divide the sale price by (1 minus the discount rate). For example, if something costs $60 after a 25% discount: $60 / (1 - 0.25) = $60 / 0.75 = $80 original price. Use the 'Find Original Price' mode in this calculator.

Question 3

How do I calculate percent off between two prices?

Accepted Answer

To find the percentage discount between an original and sale price, subtract the sale price from the original price, divide by the original price, and multiply by 100. Example: Original $120, sale $90: ($120 - $90) / $120 x 100 = 25% off. Use the 'Find Discount %' mode in this calculator.

Question 4

Can I stack multiple discounts?

Accepted Answer

Yes, this calculator supports stacking a second discount on top of the first. When you enter a second discount, it applies to the already-discounted price, not the original price. For example, 20% off then 10% off a $100 item: first discount gives $80, second discount gives $80 x 0.9 = $72. That's different from a single 30% off, which would give $70.

Question 5

How does sales tax affect the final price?

Accepted Answer

Sales tax is calculated on the discounted price, not the original price. For example, a $100 item at 20% off becomes $80. If your sales tax is 8%, the tax is $80 x 0.08 = $6.40, making the total $86.40. This calculator includes an optional sales tax field to show you the true out-of-pocket cost.

Question 6

What is the difference between discount and markup?

Accepted Answer

A discount is a reduction from the selling price, while a markup is the amount added to the cost price to set the selling price. For example, a product that costs $50 with a 100% markup sells for $100. If that $100 product goes on sale at 50% off, it sells for $50. The 100% markup and 50% discount result in the same final price but are calculated differently.
