Percentage Increase Formula:
From: | To: |
The percentage increase per year formula calculates compound growth over time. It's commonly used in finance, economics, and population studies to project future values based on a constant annual growth rate.
The calculator uses the compound growth formula:
Where:
Explanation: The formula accounts for compounding, where each year's growth builds on the previous year's increased value.
Details: Understanding compound growth is essential for financial planning, investment analysis, inflation projections, and any scenario involving exponential change over time.
Tips: Enter the starting value, annual growth rate (as a percentage), and number of years. All values must be non-negative.
Q1: How does this differ from simple interest?
A: Simple interest calculates growth only on the original amount, while compound interest (this formula) calculates growth on both the original amount and accumulated growth.
Q2: What if the rate changes each year?
A: This calculator assumes a constant rate. For variable rates, you'd need to calculate each year separately.
Q3: Can this be used for monthly compounding?
A: Yes, but you'd need to adjust the rate (divide annual rate by 12) and period (multiply years by 12).
Q4: What are common applications of this formula?
A: Investment growth, population projections, inflation calculations, salary increases, and any scenario with steady percentage growth.
Q5: How accurate are these projections?
A: They're mathematically precise for the given inputs, but real-world growth rates often fluctuate, making long-term projections less reliable.
