About this Calculator

Calculate savings and final price from a discount percentage, or determine the discount percentage from the original and final prices.

Formula & Calculations

Formula

Savings = Original Price × (Discount % / 100)
Where:
  • Final=Price after discount
  • Original=Price before discount
  • Discount=Discount percentage

Assumptions

  • Assumes a simple percentage discount off the original price.
  • Does not account for stacking of multiple discounts or coupons.

Calculation Examples

Example 1

Inputs:Original Price: $80.00, Discount: 25%
Result:You Save: $20.00, Final Price: $60.00

A 25% discount on an $80 item saves you $20, for a final cost of $60.

Example 2

Inputs:Original Price: $120.00, Final Price: $78.00
Result:Discount: 35%, Savings: $42.00

If a $120 item is on sale for $78, that represents a 35% discount.

Frequently Asked Questions

How do I calculate a discount percentage?

Divide the savings amount by the original price and multiply by 100. For example, if a $50 item is discounted to $40, the discount is ($10 / $50) × 100 = 20%.

Can multiple discounts be combined?

Retailers often apply discounts sequentially rather than adding them. A 20% off plus 10% off does not equal 30% off. The second discount applies to the already-reduced price.
