How to calculate the number before a percentage increase
To find the original number before a percentage increase, you can reverse the calculation. Here's a step-by-step guide on how to do it.
Step 1: Understand the Percentage Increase
Percentage increase tells you how much the original number has been increased by a certain percentage. For example, if a number increases by 20%, you know that the final number is 120% of the original.
Step 2: Gather Your Numbers
You need two numbers: the final number (after the increase) and the percentage of increase. For example:
- After: 120 (the number after the increase)
- Percentage Increase: 20%
Step 3: Convert the Percentage Increase to a Decimal
Add the percentage increase to 100 to get the percentage of the original number. Then convert that percentage into a decimal. For example:
Percentage after increase=100% + 20%=120%
As a decimal: 120%=1.20
Step 4: Calculate the Original Number
To find the original number, divide the final number by the decimal from Step 3:
Original Number=Final Number / Decimal
For this example: Original Number=120 / 1.20=100
Step 5: Verify Your Result
You can verify the calculation by checking if the original number plus the percentage increase gives you the final number:
Original Number + (20% of Original Number)=Final Number
100 + (20% of 100)=120
Let's Recap:
- Understand the Percentage Increase: Know how much the number increased.
- Gather Your Numbers: After the increase and the percentage increase.
- Convert to Decimal: Add the percentage increase to 100 and convert to a decimal.
- Calculate the Original Number: Divide the final number by the decimal.
- Verify the Result: Check if adding the percentage increase to the original gives the final number.

Popular Calculations to Find the Number Before Percentage Increase
1. Original Price Before Markup
Scenario: A product costs $120 after a 20% markup. What was the original price?
Calculation: Find the original price before a 20% increase.
Let X be the original price. The final price is 120% of the original price.
$120=X × (1 + 0.20)
$120=X × 1.20
X=$120 / 1.20=$100
Result: The original price before the 20% markup was $100.
2. Salary Before Increase
Scenario: Your salary is now $55,000 after a 10% increase. What was your salary before the increase?
Calculation: Find the salary before a 10% increase.
Let X be the original salary. The current salary is 110% of the original salary.
$55,000=X × (1 + 0.10)
$55,000=X × 1.10
X=$55,000 / 1.10=$50,000
