A discount calculator computes the final price of an item after a percentage discount is applied. It shows the discount amount (how much is taken off), the final price (what you pay) and the percentage saved. It is useful for shopping, sales events and any situation where a percentage reduction is applied to a price.

1. Enter the original price.
2. Enter the discount percentage.
3. Click Calculate to see the final price and savings.

Original price: $120, discount: 25%
Discount amount: $120 × 0.25 = $30
Final price: $120 − $30 = $90

A 25% discount on $120 saves $30, leaving a final price of $90. Note that stacked discounts (e.g. 20% then 10%) are not the same as a single 30% discount — apply them sequentially for the correct result.

• Confusing discount percentage with the final price percentage — a 25% discount means you pay 75%, not 25%.
• Stacking discounts incorrectly — 20% + 10% ≠ 30% off.

What is the final price after a 20% discount on $50?

Discount = $50 × 0.20 = $10. Final price = $50 − $10 = $40.

How do I calculate the original price from a discounted price?

Original = Final Price ÷ (1 − Discount% ÷ 100). For example, if you paid $90 after a 25% discount: $90 ÷ 0.75 = $120.
