What is a Percent Increase Calculator?
A Percent Increase Calculator is a digital tool that helps you determine how much a value has increased in terms of both absolute numbers and percentages. It compares an old value with a new value and shows:
- The total increase amount.
- The percentage increase relative to the original value.
For example: If your old salary was $2,000 and your new salary is $2,400, the calculator will tell you that the increase is $400, which equals a 20% increase.
How to Use the Percent Increase Calculator
Our tool is designed to be user-friendly. Here’s how you can use it:
- Enter the Old Value – This is the starting value (e.g., your previous income, old product price, or original number).
- Enter the New Value – This is the updated or current value.
- Click on Calculate – The calculator will show:
- Increase Amount (new value – old value).
- Percent Increase (increase ÷ old value × 100).
- Reset Anytime – Use the reset button to clear all fields and start again.
Formula Behind the Calculator
The formula used in the tool is:
[
\text{Percent Increase} = \frac{(\text{New Value} - \text{Old Value})}{\text{Old Value}} \times 100
]
- Increase Amount = New Value – Old Value
- Percent Increase = (Increase ÷ Old Value) × 100
This ensures accurate and reliable results.
Example Calculations
Let’s look at some practical examples:
Example 1: Salary Increase
- Old Value: $3,000
- New Value: $3,600
- Increase = $600
- Percent Increase = (600 ÷ 3000) × 100 = 20%
Example 2: Product Price Change
- Old Value: $50
- New Value: $65
- Increase = $15
- Percent Increase = (15 ÷ 50) × 100 = 30%
Example 3: Investment Growth
- Old Value: $10,000
- New Value: $12,500
- Increase = $2,500
- Percent Increase = (2500 ÷ 10000) × 100 = 25%
