How it works
The saving is the original price multiplied by the discount rate: Saving = Price × (Discount% ÷ 100). The sale price is the original price minus the saving. If a tax rate is added, tax is applied to the discounted price to give the final total.
Frequently asked questions
How do I calculate a percentage off?
Multiply the original price by the discount percentage divided by 100 to get the saving, then subtract it from the original price.
Does the calculator include sales tax?
Yes, optionally. Enter a tax rate and it is applied to the discounted price so you see the real amount due at checkout.
Can I stack two discounts?
Stacked discounts apply one after another, not added together. A 20% then 10% off is 0.8 × 0.9 = 0.72 of the price, a 28% total reduction.
