1. What is the Percentage Increase Calculator?

The Percentage Increase Calculator Over Time calculates how a value grows when subject to compound percentage increases over multiple periods. It's useful for financial projections, investment growth, population studies, and any scenario involving compound growth.

2. How Does the Calculator Work?

The calculator uses the compound growth formula:

Where:

• Old Value — The starting amount
• Rate — The percentage growth rate per period
• Periods — The number of growth periods

Explanation: The formula accounts for compounding, where each period's growth builds on the previous period's total, not just the original amount.

3. Importance of Compound Growth Calculation

Details: Understanding compound growth is essential for financial planning, investment analysis, business projections, and understanding long-term trends in various fields.

4. Using the Calculator

Tips: Enter the starting value, growth rate (as a percentage), and number of periods. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between simple and compound growth?
A: Simple growth applies the percentage only to the original amount each period. Compound growth applies it to the current total, leading to exponential growth.

Q2: How does changing the compounding frequency affect results?
A: More frequent compounding (monthly vs. annually) leads to higher final amounts. This calculator assumes growth compounds once per period.

Q3: Can this calculator show year-by-year growth?
A: No, it shows only the final result. For year-by-year breakdowns, you would need to calculate each period separately.

Q4: What's the Rule of 72 and how does it relate?
A: The Rule of 72 estimates doubling time (72 ÷ rate). It's a quick mental check for compound growth calculations.

Q5: Can I use this for negative growth rates?
A: While the math works for negative rates (showing depreciation), this calculator is designed for positive growth scenarios.
