1. What is Percentage Increase?

Percentage increase measures how much a value has grown over time, expressed as a percentage of the original value. It's commonly used in finance, economics, and statistics to track growth rates.

2. How Does the Calculator Work?

The calculator uses the compound percentage increase formula:

Where:

• Old Value — The initial amount or value
• Rate — The annual percentage increase rate
• Years — The number of years for the calculation

Explanation: The formula accounts for compounding growth, where each year's increase is calculated on the previous year's total value.

3. Applications of Percentage Increase

Details: This calculation is essential for financial planning, investment growth projections, salary increases, inflation adjustments, and business revenue forecasting.

4. Using the Calculator

Tips: Enter the original value, annual percentage increase rate, and number of years. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between simple and compound percentage increase?
A: Simple increase calculates growth only on the original amount each year, while compound increase calculates growth on the accumulated total each year.

Q2: How do I calculate monthly instead of yearly increases?
A: Divide the annual rate by 12 for monthly rate, and multiply years by 12 for total months.

Q3: Can this calculator handle decreasing values?
A: Yes, enter a negative percentage for a decrease (e.g., -5% for a 5% annual decrease).

Q4: What's the Rule of 72 for percentage growth?
A: Divide 72 by the growth rate to estimate how many years it takes to double your investment (e.g., at 6%, it takes ~12 years to double).

Q5: How accurate are these projections?
A: They're mathematically accurate for the given inputs, but real-world results may vary due to changing rates and other factors.
