Discount Amount = Original Price × (Discount % ÷ 100). Final Price = Original Price − Discount Amount.
Can I work out the discount percentage if I only know the original and sale price?

Does this calculate savings on multiple items?
Yes — enter a quantity to see the total original price, total final price, and total savings across all units.
Is this calculator free to use?
Yes, completely free, with no sign-up and no limit on how many times you use it.
