How to Calculate Percentage Increase

A percentage increase calculator helps you measure growth between an original value and a new value. Here's how it works with a real-world example:

Example Scenario:

A company's revenue grows from $50,000 to $65,000. To find the percentage increase:

1. Subtract the original value from the new value:
   $65,000 - $50,000 = $15,000 increase
2. Divide the increase by the original value:
   $15,000 ÷ $50,000 = 0.3
3. Multiply by 100 to convert to a percentage:
   0.3 × 100 = 30% growth

Final Result:

The company's revenue increased by 30%.

Percentage Change Calculator (Increase or Decrease)

A percentage change calculator determines the difference between two values, whether it's growth or decline.

Example:

If website visits drop from 1,200 to 900, the percentage decrease is:

1. Subtract the original value from the new value:
   900 - 1,200 = -300
2. Divide the change by the original value:
   -300 ÷ 1,200 = -0.25
3. Multiply by 100 to convert to percentage:
   -0.25 × 100 = -25% (Decrease)

Rate of Change Calculator

A rate of change calculator measures how quickly a value increases or decreases over time.

Example:

If a stock price rises from $100 to $150 in a year:

1. Subtract the original value from the new value:
   150 - 100 = 50
2. Divide the change by the original value:
   50 ÷ 100 = 0.5
3. Multiply by 100 to convert to percentage:
   0.5 × 100 = 50% annual growth
