Rate Of Increase Calculator

Have you ever wondered how much something has grown—whether it’s sales, population, investment returns, or even exam scores? Manually figuring out the rate of increase can be confusing, especially with large numbers.

That’s where a Rate of Increase Calculator comes in handy. This tool helps you find the percentage change between an original value and a new value. It’s useful for:

  • Businesses tracking sales growth
  • Investors measuring returns
  • Students analyzing data
  • Economists studying inflation and population changes

By entering just two numbers, the calculator instantly shows you the rate of increase in percentage form.

How to Use the Rate of Increase Calculator

Using this tool is simple:

  1. Enter the Original Value.
    • Example: 1,000.
  2. Enter the New Value.
    • Example: 1,250.
  3. Click Calculate.
    • The calculator instantly shows the rate of increase (%).
  4. Review the Result.
    • If the percentage is positive, it’s an increase.
    • If the percentage is negative, it’s actually a decrease.

Practical Example

Imagine a company’s sales grew from $50,000 last year to $65,000 this year.

  • Original Value = $50,000
  • New Value = $65,000

Rate of Increase = (New – Old) ÷ Old × 100
= (65,000 – 50,000) ÷ 50,000 × 100
= 15,000 ÷ 50,000 × 100
= 30% increase

👉 This means sales went up by 30% compared to last year.
