How to add percentage to a number

Adding a percentage to a number is easy and useful for finding an increased value. Let's learn how to do it step by step!

Step 1: Understand What Adding a Percentage Means

When you add a percentage to a number, you're increasing that number by a certain portion of itself. It's like applying a markup to a product price!

Step 2: Gather Your Numbers

You'll need two things: the original number and the percentage you want to add. For example:

  • Original Number: 200
  • Percentage to Add: 15%

Step 3: Convert the Percentage to a Decimal

To use percentages in calculations, convert the percentage to a decimal by dividing by 100:

Decimal = Percentage / 100

In this example: Decimal = 15 / 100 = 0.15

Step 4: Multiply the Original Number by the Decimal

Next, multiply the original number by the decimal to find the amount to add:

Amount to Add = Original Number × Decimal

In our example: Amount to Add = 200 × 0.15 = 30

Step 5: Add the Amount to the Original Number

Finally, add the calculated amount to the original number to find the new, increased value:

New Value = Original Number + Amount to Add

In this case: New Value = 200 + 30 = 230

Let's Recap:

  • Adding a Percentage increases the original number by a certain portion.
  • Gather Your Numbers: The original number and the percentage to add.
  • Convert to Decimal: Divide the percentage by 100.
  • Multiply the Original Number by the Decimal to find the amount to add.
  • Add the Amount to the original number to get the increased value.

Popular Percentage Addition Calculations

1. Sales Tax Calculation

Scenario: You're buying a product that costs $50, and the sales tax is 8%.

Calculation: Add 8% to $50.

$50 × 0.08 = $4 (Amount to Add)

$50 + $4 = $54 (Total Price)

Result: After adding 8% sales tax, the total price is $54.

2. Salary Increase Calculation

Scenario: You received a 5% raise on your annual salary of $40,000.

Calculation: Add 5% to $40,000.

$40,000 × 0.05 = $2,000 (Amount to Add)

$40,000 + $2,000 = $42,000 (New Salary)

Result: After the raise, your new annual salary is $42,000.

3. Discount Calculation

Scenario: You found a pair of shoes for $80, and the store offers a 25% discount.

Calculation: Subtract 25% from $80.

$80 × 0.25 = $20 (Amount to Subtract)

$80 - $20 = $60 (Discounted Price)

Result: After the 25% discount, the price of the shoes is $60.

4. Investment Growth Calculation

Scenario: You invested $10,000 in a fund, and it grows by 12% over the year.

Calculation: Add 12% to $10,000.

$10,000 × 0.12 = $1,200 (Amount to Add)

$10,000 + $1,200 = $11,200 (New Value)

Result: After one year, your investment is worth $11,200.

5. Markup Calculation

Scenario: You bought a product for $150 and want to sell it with a 30% markup.

Calculation: Add 30% to $150.

$150 × 0.30 = $45 (Amount to Add)

$150 + $45 = $195 (Selling Price)

Result: After adding a 30% markup, the selling price is $195.
