How to Calculate Discount: Formula, Examples & Easy Method
Learn how to calculate discount percentage, discount amount and final price with simple formulas and examples.
What is a Discount?
A discount is a reduction in the original price of a product or service. Discounts are commonly offered during sales, festivals, online shopping events and special promotions.
For example, if a product costs ₹1,000 and the seller offers a 20% discount, the customer pays less than the original price.
Discount Formula
Discount Amount = (Original Price × Discount %) ÷ 100
Once you calculate the discount amount, subtract it from the original price to find the final selling price.
Final Price = Original Price − Discount Amount
How to Calculate Discount – Example
Suppose a product has an original price of ₹1,000 and the discount is 20%.
First, calculate the discount amount:
Discount = (₹1,000 × 20) ÷ 100
Discount = ₹200
Now subtract the discount from the original price:
Final Price = ₹1,000 − ₹200 = ₹800
Therefore, after a 20% discount, the customer pays ₹800.
Example: 10% Discount
Suppose the original price of a product is ₹2,000 and the discount is 10%.
Discount = (₹2,000 × 10) ÷ 100 = ₹200
Final Price = ₹2,000 − ₹200 = ₹1,800
The customer saves ₹200 and pays ₹1,800.
Example: 30% Discount
Consider a product priced at ₹5,000 with a 30% discount.
Discount = (₹5,000 × 30) ÷ 100 = ₹1,500
Final Price = ₹5,000 − ₹1,500 = ₹3,500
Therefore, the customer saves ₹1,500 and pays ₹3,500.
Quick Discount Examples
| Original Price | Discount | Discount Amount | Final Price |
|---|---|---|---|
| ₹1,000 | 10% | ₹100 | ₹900 |
| ₹2,000 | 20% | ₹400 | ₹1,600 |
| ₹5,000 | 30% | ₹1,500 | ₹3,500 |
How to Calculate Discount Percentage
If you know the original price and the amount saved, you can calculate the discount percentage using this formula:
Discount % = (Discount Amount ÷ Original Price) × 100
For example, if a product originally costs ₹2,000 and you save ₹400:
Discount % = (400 ÷ 2,000) × 100
Discount % = 20%
How to Find the Original Price After Discount
Sometimes you know the final price and discount percentage but want to find the original price.
Original Price = Final Price ÷ (1 − Discount Rate)
For example, if the final price is ₹800 after a 20% discount:
Original Price = ₹800 ÷ 0.80
Original Price = ₹1,000
Discount Amount vs Final Price
It is important to understand the difference between the discount amount and the final price.
- Original Price: Price before discount.
- Discount Amount: Money saved because of the discount.
- Final Price: Amount paid after subtracting the discount.
Common Discount Calculation Mistakes
- Calculating the discount percentage on the wrong price.
- Forgetting to divide the percentage by 100.
- Confusing discount amount with final selling price.
