Discount Calculator

Calculate discount amount, final price, and total savings instantly. Supports percentage discounts, fixed amount discounts, and reverse sale price calculation.

How Discount Calculator Works

Discounts are calculated based on either a percentage or a fixed amount deduction from the original price. This calculator supports both models and instantly returns the final price and total savings.

Discount Formulas

Percent Mode:
  Discount = Original Price × (Discount% / 100)
  Final Price = Original Price − Discount

Amount Mode:
  Final Price = Original Price − Discount Amount

When to Use Percent vs Amount Discount

  • Use % Discount when sale tags say “20% OFF”, “Save 35%”, etc.
  • Use Fixed Discount when coupons say “Save $10”, “Flat $50 OFF”.

Common Discount Examples

  • 20% discount on $200 → saves $40 (final price $160)
  • $50 fixed discount on $300 → final price $250
  • 5% cashback equivalent discount can be calculated similarly
