1. What is Percent Increase Over Time?

The percent increase over time calculator shows how a value grows when it's increased by a constant percentage rate over multiple periods. This is commonly used for financial calculations like investment growth, inflation adjustments, or population growth.

2. How Does the Calculator Work?

The calculator uses the compound growth formula:

Where:

• Old Value — The initial amount or value
• Rate — The percentage increase per period
• Periods — The number of time periods (years, months, etc.)

Explanation: The formula accounts for compounding - each period's increase is calculated on the new value that includes previous increases.

3. Importance of Compound Growth Calculation

Details: Understanding compound growth is essential for financial planning, investment analysis, and predicting long-term trends. Small percentage increases can lead to significant growth over time.

4. Using the Calculator

Tips: Enter the original value, the periodic percentage increase rate, and the number of periods. 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 each period's growth on the original value, while compound growth calculates each period's growth on the accumulated value.

Q2: Can I use this for monthly calculations?
A: Yes, just make sure your rate and periods are consistent (e.g., monthly rate with number of months).

Q3: How does this relate to the Rule of 72?
A: The Rule of 72 estimates doubling time (72/rate) and is derived from this compound growth formula.

Q4: What if my rate changes over time?
A: This calculator assumes a constant rate. For variable rates, you'd need to calculate each period separately.

Q5: Can this be used for decreasing values?
A: Yes, use a negative percentage for decrease (e.g., depreciation or decay calculations).
