Discount Calculator
A Discount Calculator helps you quickly find the discount amount and the final price of a product after applying a percentage discount. Instead of calculating discounts manually, you can enter the original price and discount percentage to get an instant result.
Calculator Pool’s free Discount Calculator is useful for shopping, retail pricing, sales offers, business calculations, and everyday purchases.
Whether you want to calculate a percentage discount, find the discounted price, or understand how much money you are saving, this online discount calculator makes the process simple.
What Is a Discount Calculator?
A Discount Calculator is an online tool used to determine how much a product or service price is reduced by a percentage discount.
For example, if an item costs ₹2,000 and has a 20% discount, the discount amount is:
₹2,000 × 20% = ₹400
The final price is:
₹2,000 − ₹400 = ₹1,600
So, after a 20% discount, you would pay ₹1,600.
How to Use the Discount Calculator
Using Calculator Pool’s Discount Calculator online is simple.
Step 1: Enter the Original Price
Enter the price of the product before the discount.
For example:
₹2,000
Step 2: Enter the Discount Percentage
Enter the percentage discount offered by the seller.
For example:
20%
Step 3: Calculate
Click the Calculate button.
The calculator will show:
- Original price
- Discount amount
- Final price after discount
This lets you understand both the amount saved and the amount you actually need to pay.
Discount Formula
The basic formula for calculating a discount is:
Discount Amount = Original Price × Discount Percentage ÷ 100
The final selling price after discount is:
Final Price = Original Price − Discount Amount
Example
Suppose:
Original Price = ₹5,000
Discount = 15%
First calculate the discount:
₹5,000 × 15 ÷ 100 = ₹750
Then calculate the final price:
₹5,000 − ₹750 = ₹4,250
Therefore:
Discount Amount = ₹750
Final Price = ₹4,250
How to Calculate Percentage Discount
A percentage discount shows how much the original price is reduced.
For example, a 10% discount means you pay 90% of the original price.
If the original price is ₹1,000:
10% discount = ₹100
Final price:
₹1,000 − ₹100 = ₹900
This basic percentage discount calculation is commonly used in shopping and promotional offers.
Discount Calculator Examples
Example 1: 10% Discount
Original Price: ₹1,000
Discount: 10%
Discount Amount:
₹1,000 × 10 ÷ 100 = ₹100
Final Price:
₹1,000 − ₹100 = ₹900
You save ₹100.
Example 2: 20% Discount
Original Price: ₹2,500
Discount: 20%
Discount Amount:
₹2,500 × 20 ÷ 100 = ₹500
Final Price:
₹2,500 − ₹500 = ₹2,000
You save ₹500.
Example 3: 25% Discount
Original Price: ₹4,000
Discount: 25%
Discount Amount:
₹4,000 × 25 ÷ 100 = ₹1,000
Final Price:
₹4,000 − ₹1,000 = ₹3,000
You save ₹1,000.
Example 4: 50% Discount
Original Price: ₹1,200
Discount: 50%
Discount Amount:
₹1,200 × 50 ÷ 100 = ₹600
Final Price:
₹1,200 − ₹600 = ₹600
A 50% discount means the final price is half the original price.
Discount Percentage Table
Here are some simple examples:
| Original Price | Discount | Discount Amount | Final Price |
|---|---|---|---|
| ₹500 | 10% | ₹50 | ₹450 |
| ₹1,000 | 10% | ₹100 | ₹900 |
| ₹1,000 | 20% | ₹200 | ₹800 |
| ₹2,000 | 25% | ₹500 | ₹1,500 |
| ₹5,000 | 30% | ₹1,500 | ₹3,500 |
| ₹10,000 | 50% | ₹5,000 | ₹5,000 |
How to Calculate the Final Price After a Discount
There are two simple ways to calculate the final price.
Method 1: Calculate the Discount First
Use:
Discount Amount = Original Price × Discount ÷ 100
Then:
Final Price = Original Price − Discount Amount
Method 2: Calculate the Remaining Percentage
If the discount is 20%, then you pay:
100% − 20% = 80%
So:
Final Price = Original Price × 80 ÷ 100
For a ₹2,000 product:
₹2,000 × 80 ÷ 100 = ₹1,600
Both methods produce the same result.
How Much Do You Save With a Discount?
The amount you save depends on both the original price and the discount percentage.
For example:
A 10% discount on ₹500 saves only ₹50.
A 10% discount on ₹10,000 saves ₹1,000.
This is why it is useful to calculate the actual discount amount rather than looking only at the percentage.
Discount Calculator for Shopping
A discount calculator is particularly useful during sales and promotional events.
Stores may advertise offers such as:
- 10% off
- 20% off
- 30% off
- 50% off
- 70% off
The percentage alone does not tell you the final amount you will pay.
For example, a 40% discount on a ₹500 item saves ₹200, while a 40% discount on a ₹5,000 item saves ₹2,000.
Using an online discount calculator makes it easy to calculate the actual savings.
Discount Calculator for Multiple Items
Suppose you are buying several products with different prices.
You can calculate the discount on each item separately.
For example:
Product A: ₹2,000 at 10% discount
Product B: ₹1,500 at 20% discount
Product A discount:
₹200
Product A final price:
₹1,800
Product B discount:
₹300
Product B final price:
₹1,200
Total final price:
₹3,000
This can help you estimate the total cost of a shopping basket.
Successive Discounts
Sometimes a seller applies more than one discount to the same product.
For example:
20% discount followed by 10% discount
These discounts are generally applied one after another rather than simply adding them together.
Suppose the original price is ₹1,000.
After a 20% discount:
₹1,000 × 80% = ₹800
Then apply the additional 10% discount:
₹800 × 90% = ₹720
The final price is:
₹720
The combined effective discount is therefore:
28%, not 30%.
This is an important distinction when evaluating multiple promotional offers.
Discount vs Cashback
A discount and cashback are not necessarily the same thing.
Discount
A discount usually reduces the price of the product at the time of purchase.
Cashback
Cashback generally provides money back according to the terms of a payment provider, retailer, card, or promotional program.
For example, a product may have:
₹1,000 price + 20% discount
which means you pay ₹800 before considering any other offer.
Cashback may work differently depending on the specific terms.
Always read the promotion conditions before assuming the advertised percentage represents the final cost.
Discount vs Sale Price
The original price is the price before the discount.
The discount amount is the money removed from that price.
The sale price or final price is the amount remaining after the discount.
For example:
Original Price: ₹2,000
Discount: ₹400
Final Price: ₹1,600
Understanding these three values helps you quickly evaluate a sale.
How to Find the Discount Percentage From Original and Sale Price
Sometimes you know the original price and the final selling price but want to find the percentage discount.
Use:
Discount Percentage = ((Original Price − Sale Price) ÷ Original Price) × 100
Example
Original Price:
₹2,000
Sale Price:
₹1,500
Discount:
₹2,000 − ₹1,500 = ₹500
Discount percentage:
₹500 ÷ ₹2,000 × 100 = 25%
Therefore, the item was sold at a 25% discount.
Common Discount Percentages
Some discount percentages are easy to calculate mentally.
10% Discount
Divide the original price by 10.
10% of ₹2,000 = ₹200
20% Discount
Calculate 10% and double it.
20% of ₹2,000 = ₹400
25% Discount
Calculate one-quarter.
25% of ₹2,000 = ₹500
50% Discount
Take half.
50% of ₹2,000 = ₹1,000
75% Discount
Pay only 25% of the original price.
75% discount on ₹2,000 means:
Final price = ₹500
Why Use a Discount Calculator?
Manual calculations are easy when dealing with simple numbers, but an online calculator is useful when prices or discount percentages become more complicated.
A discount calculator can help you:
- Calculate discount amounts quickly
- Find the final price
- Compare promotional offers
- Estimate shopping savings
- Check sale prices
- Understand successive discounts
- Calculate percentage discounts
- Verify a retailer’s advertised price
Discount Calculator for Businesses
Businesses and retailers can also use percentage calculations when setting prices or evaluating promotions.
For example, a retailer may need to determine:
Original price → Discount amount → Selling price
Discount calculations can also be useful for estimating promotional pricing, sale offers, and customer savings.
However, actual business pricing may also involve taxes, shipping costs, platform fees, commissions, and other expenses that are not included in a basic discount calculation.
Discount and GST
A product’s discount and GST calculation can be separate steps.
For example, suppose:
Original price = ₹1,000
Discount = 10%
Discount amount:
₹100
Price after discount:
₹900
If GST is then applicable, the tax calculation depends on the applicable tax rules and whether the stated price is before or after tax.
For tax-related calculations, use the relevant GST rules and verify the applicable rate rather than assuming a particular rate.
You can also use the GST Calculator on Calculator Pool for GST-related calculations.
Important Things to Check Before Comparing Discounts
A large percentage discount does not always mean the lowest final price.
Before purchasing, compare:
- Original price
- Discount percentage
- Actual discount amount
- Final selling price
- Shipping charges
- Applicable taxes
- Additional fees
- Terms and conditions
For example, a 30% discount on one product may still result in a higher final price than a different product with a smaller discount.
Always compare the final price, not just the advertised percentage.

A Discount Calculator helps you calculate the amount saved on a product and determine the final price after applying a percentage discount.
The basic formulas are:
Discount Amount = Original Price × Discount Percentage ÷ 100
Final Price = Original Price − Discount Amount
For example, if a ₹5,000 product has a 20% discount:
Discount = ₹1,000
Final Price = ₹4,000
For multiple or successive discounts, each discount should generally be calculated on the reduced price from the previous step.
