1. Percent Off (Percentage Discount)

A percentage off means you have churned a percentage of the original value. So, it works like a simple percentage calculator.

Normally, you might have an original price and a percentage off. So, a percentage-off calculator will find the value after applying that percent and show how much money you saved.

There are four values involved:

  • Price before discount
  • Discount (%)
  • Price after discount
  • You saved

Our calculator goes a step further. It works in both directions.

Even if you have the price after the discount and want to know how much money you saved, it will still give you the result.

So, whether you want to reverse-calculate the original price, find the price after the discount, or find the percentage discount on a fixed amount, this calculator works in all situations.

Thus, this calculator is a great tool for shoppers and retailers for everyday use.

How to calculate percent off?

For your understanding, let’s see what formula is used to find the percentage off and savings.

Price after discount = Original Price × (1 − Discount Percentage / 100)

Savings = Original Price − Price after discount

To make it quite simple fo everyone, we can say, multiply the original price by the percentage amount over 100. For instance, to find 20% off any price, multiply it by 20/100, that is 0.20/ To calculate 55% off, multiply it by 55/100, that’s 0.55, and so on!

Understand with an example:

Let’s say you bought something that originally cost $100 and it was 20% off. Here’s what you pay and save:

percent off calculator example
Original Price = $100, Discount = 20%

Price after discount = 100 × (1 − 0.20) = 100 × 0.80 = $80

Savings = 100 − 80 = $20

So, you are paying $80, which is $20 less than the original price.

Manual Calculation:

If you still want to learn and do manual calculations using a physical calculator, here’s how to do it:

  • Convert the discount percentage to a decimal by dividing by 100.
  • Multiply the original price by (1 minus that decimal).
  • The result is the discounted price.
  • Subtract the discounted price from the original price to find savings.

Using Our Calculator:

Our Percent Off calculator makes things easy for you. Simply enter any two known values (e.g., original price and discount), and our calculator instantly computes the price after discount and your savings.

2. Fixed Amount Discount

A fixed amount discount reduces the original price by a specific dollar amount, such as $15 off a product. This is a simple subtraction calculator. But what makes the A Calculator Online‘s calculator special is that it also works in reverse.

There are three values involved:

  • Price before discount
  • Discount amount
  • Price after discount

No matter which two values you have, it will find the third one for you.

Formula used in fixed amount discount calculator:

If you want to learn this by formula, the fixed amount discount calculator works on this formula:

Price after discount = Original Price − Discount Amount

Savings = Discount Amount

Manual Calculation:

Here’s how to calculate manually:

  • Take the original price.
  • Subtract the fixed discount amount.
  • The result is the price after the discount.

Example for fixed amount calculator:

You were buying something with a price tag of $100, but now they want to offer you a $15 loyalty discount. Here is what you will pay:

fixed amount discount calculator example
Original Price = $100, Discount = $15

Price after discount = 100 − 15 = $85

Savings = $15

So, here you are paying $85, which is $15 lower than your original price.

3. Double Discount

Double discount means applying two consecutive percentage discounts to a product, one after the other. For example, a 10% discount followed by a 20% discount.

The major difference in this calculator and other percent-off calculators is that the second percentage discount is applied after the first discount has been deducted from the original price.

So, it’s not as simple as adding the two percentages together.

You might think applying 10% and 20% discounts equals a 30% discount—but it doesn’t work that way. The second discount is applied to a reduced price, not the original one.

The formula used in the double discount calculator:

Price after first discount = Original Price × (1 − Discount1 / 100)

Final Price after second discount = Price after first discount × (1 − Discount2 / 100)

Manual Calculation:

  • Apply the first discount percentage to the original price, as we have discussed earlier in the percent off calculation
  • Apply the second discount percentage to the result of the first discount.
  • The final result is the price after both discounts.

Example:

Let’s say there’s a product originally priced at $100. It’s Black Friday, and the store is offering an additional 20% off after the regular 10% discount:

double discount calculator with example
Original Price = $100, Discount1 = 10%, Discount2 = 20%

After first discount = 100 × 0.90 = $90

After second discount = 90 × 0.80 = $72

Using Our Calculator:

Enter the original price and the two discount percentages. The calculator instantly shows the final discounted price—no need for multi-step calculations.

4. Triple Discount

Just like the double discount, the triple discount applies three consecutive percentage discounts sequentially to a product.

It works the same way, but with one more discount layer.

Formula used:

Here is the formula used in the triple discount calculator:

Price after first discount = Original Price × (1 − Discount1 / 100)

Price after second discount = Price after first discount × (1 − Discount2 / 100)

Final Price after third discount = Price after second discount × (1 − Discount3 / 100)

Manual Calculation:

  • Apply the first discount to the original price, as we have discussed earlier in the percent off calculation.
  • Apply the second discount to the result of the first.
  • Apply the third discount to the result of the second.

Example:

Let’s expand the previous example. Now the store clerk is your friend and offers an extra 5% cut. Here is how it will be calculated now:

triple discount calculator with example
Original Price = $100, Discount1 = 10%, Discount2 = 20%, Discount3 = 5%

After first discount = 100 × 0.90 = $90

After second discount = 90 × 0.80 = $72

After third discount = 72 × 0.95 = $68.40

Using Our Calculator:

Input the original price and the three discount percentages. Our calculator performs all the steps and instantly shows you the final price without getting involved in the complex manual calculations.

  1. How to calculate 20 percent off?

    Here is how to easily find 20 percent off any value with any basic calculator: Multiply the original price by 0.20 to get the discount, then subtract it from the original price.

    Example:

    If the price is $50:
    Discount = 50 × 0.20 = $10
    Final Price = 50 − 10 = $40

  2. How to calculate 10 percent off a price?

    Here is the fastest way to find 10 percent off a price. Multiply the original price by 0.10 and subtract the result from the original price.

    Example:

    If the price is $80:
    Discount = 80 × 0.10 = $8
    Final Price = 80 − 8 = $72

  3. What is 30 off 20?

    We can easily find 30 off 20 by using the formula, that is multiply 20/100, that’s 0.20 with the price

    Discount = 20 × 0.30 = $6
    Final Price = 20 − 6 = $14

  4. What is 25% off 25?

    We can easily find 25% off 25 by using the percentage off formula, that is multiply 25/100, that’s 0.25 with the price.

    Discount = 25 × 0.25 = $6.25
    Final Price = 25 − 6.25 = $18.75
