Calculate discounts, sale prices, and savings with precision. Find out the final price after discount, percentage off, or the amount you'll save on purchases.
Discounts are reductions in the original price of a product or service. They are commonly used in retail and business as incentives for customers to make purchases, move inventory, or gain a competitive advantage.
Sale Price = Original Price × (1 - Discount Percentage / 100)
or
Sale Price = Original Price - Discount Amount
The sale price is what the customer pays after the discount is applied to the original price.
Discount Amount = Original Price × (Discount Percentage / 100)
The discount amount is the actual dollar value saved from the original price due to the discount.
Original Price = Sale Price / (1 - Discount Percentage / 100)
If you know the sale price and discount percentage, you can calculate what the original price was before the discount.
Discount Percentage = ((Original Price - Sale Price) / Original Price) × 100
The discount percentage represents the proportion of the original price that has been deducted.
The most common type of discount, where a percentage of the original price is reduced. For example, a 20% discount on a $100 item results in a $20 reduction, making the sale price $80.
These specify a fixed amount to be deducted from the original price. For example, "$10 off" a $50 item would result in a sale price of $40.
These offers provide a second item for free or at a reduced price when one item is purchased at the regular price. For example, "Buy one, get one free" effectively gives a 50% discount when purchasing two identical items.
These offer reduced prices when items are purchased in larger quantities. For example, "10% off when you buy 5 or more" or tiered pricing structures that reduce the per-unit price as quantity increases.
These are typically deeper discounts offered to move seasonal inventory or clear out old stock. They can range from 30% to 70% or more off the original price.
Taxes are typically calculated on the sale price after discounts are applied, not on the original price. However, this can vary by location and tax regulations.
When multiple discounts are applied to the same item, they may be calculated sequentially rather than being added together. For example, a 20% discount followed by an additional 10% discount is not the same as a 30% discount. The effective discount would be:
Effective Discount = 1 - (1 - 0.2) × (1 - 0.1) = 1 - 0.8 × 0.9 = 1 - 0.72 = 0.28 or 28%
