Discount Calculator | Calculate Discount & Price After Discount

Use this discount calculator to calculate the discount amount, savings, and price after discount. Enter the original price and discount percentage to find the final price you need to pay. You can also use the calculator to find the discount percentage from the original and sale prices or calculate the original price from a discounted price.

How to Calculate Discount

To calculate the discount amount, multiply the original price by the discount percentage and divide by 100.

Discount Amount = Original Price × (Discount Percentage ÷ 100)

For example, if an item costs ₹2,000 and has a 20% discount:

Discount Amount = ₹2,000 × (20 ÷ 100) = ₹400

You save ₹400 on the purchase.

How to Calculate Price After Discount

To find the price after discount, subtract the discount amount from the original price.

Price After Discount = Original Price − Discount Amount

For a ₹2,000 item with a 20% discount:

Discount Amount = ₹2,000 × 20 ÷ 100 = ₹400

Price After Discount = ₹2,000 − ₹400 = ₹1,600

Therefore, you pay ₹1,600 after the discount. The same result can be calculated directly using:

Price After Discount = Original Price × (1 − Discount Percentage ÷ 100)

Discount Percentage Formula

If you know the original price and the sale price, you can calculate the actual discount percentage.

Discount Percentage = ((Original Price − Sale Price) ÷ Original Price) × 100

For example, if an item was originally ₹2,000 and is now available for ₹1,600:

Discount Amount = ₹2,000 − ₹1,600 = ₹400

Discount Percentage = (₹400 ÷ ₹2,000) × 100 = 20%

So, the item is being sold at a 20% discount. This calculation is useful when a seller shows the original and sale prices but you want to know the actual percentage discount.

How to Find the Original Price After a Discount

If you know the sale price and the discount percentage, you can work backward to find the original price.

Original Price = Sale Price ÷ (1 − Discount Percentage ÷ 100)

For example, if an item costs ₹1,600 after a 20% discount:

Original Price = ₹1,600 ÷ (1 − 20 ÷ 100)

Original Price = ₹1,600 ÷ 0.80 = ₹2,000

So, the original price was ₹2,000.

10%, 20%, and 30% Discount Examples

The amount you save depends on the original price.

For example, a 20% discount on ₹5,000 means you save ₹1,000 and pay ₹4,000.

How to Calculate 20% Discount

To calculate a 20% discount, multiply the original price by 20 and divide by 100.

For a ₹3,000 item:

Discount = ₹3,000 × 20 ÷ 100 = ₹600

Price After Discount = ₹3,000 − ₹600 = ₹2,400

So, a 20% discount on ₹3,000 gives a saving of ₹600, and the discounted price is ₹2,400.

How to Calculate 10% Discount

A 10% discount is calculated by multiplying the original price by 10 and dividing by 100.

For a ₹2,500 item:

Discount = ₹2,500 × 10 ÷ 100 = ₹250

Price After Discount = ₹2,500 − ₹250 = ₹2,250

Therefore, you save ₹250 and pay ₹2,250.

What Is the Difference Between Discount Amount and Discount Percentage?

The discount percentage tells you how large the reduction is relative to the original price.

The discount amount tells you exactly how much money is reduced from the original price.

For example, a 20% discount on ₹1,000 is ₹200, while a 20% discount on ₹5,000 is ₹1,000. The percentage is the same, but the amount saved is different.

Are Two Discounts of 20% and 10% Equal to a 30% Discount?

No. Two successive discounts are not normally added together.

For example, suppose an item costs ₹1,000 and receives a 20% discount followed by another 10% discount.

After the first 20% discount:

₹1,000 − ₹200 = ₹800

The second 10% discount is applied to ₹800:

₹800 − ₹80 = ₹720

The final price is ₹720, meaning the total saving is ₹280 or 28%, not 30%.

This happens because the second discount is calculated on the already-discounted price.
