What is a discount rate calculator?
If you enter the original price and the discount rate, the actual discount amount and the final price are calculated instantly. Conversely, you can also calculate the discount rate by entering the original price and the final price.
Discount Rate Calculation Formula
Discount Amount = Original Price × Discount Rate ÷ 100
Final Price = Original Price × (1 – Discount Rate ÷ 100)
Reverse Discount Rate = (Original Price – Final Price) ÷ Original Price × 100
Final Price = Original Price × (1 – Discount Rate ÷ 100)
Reverse Discount Rate = (Original Price – Final Price) ÷ Original Price × 100
Use this when comparing discount rates for various products while shopping. Even with the same discount rate, the amount saved can vary significantly depending on the original price.
Frequently Asked Questions
How is the discount rate calculated?
The discount rate (%) = (Original Price – Discounted Price) ÷ Original Price × 100. Example: If the price is lowered from 100,000 won to 70,000 won, (100,000 - 70,000) ÷ 100,000 × 100 = 30%.
How is the calculation applied when multiple discounts are applied?
If there is an additional 10% discount after a 30% discount, 0.7 × 0.9 = 0.63, which means a 37% discount. Simply adding the discount rates (40%) results in an error.
