1. What is Exponential Growth?

Exponential growth describes a process where the growth rate of a value is proportional to its current value, leading to growth that accelerates over time. This pattern is common in finance, population studies, and many natural phenomena.

2. How Does the Calculator Work?

The calculator uses the exponential growth formula:

Where:

• \( Initial \) — Starting value (in £)
• \( Rate \) — Annual growth rate (as percentage)
• \( Time \) — Time period in years
• \( e \) — Euler's number (~2.71828)

Explanation: The formula calculates how an initial amount grows when compounded continuously at a constant rate over time.

3. Importance of Exponential Growth Calculation

Details: Understanding exponential growth is crucial for financial planning, investment analysis, population projections, and many business applications where growth compounds over time.

4. Using the Calculator

Tips: Enter the initial value in £, growth rate as a percentage (e.g., 5 for 5%), and time period in years. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How is this different from compound interest?
A: This calculates continuous compounding, while standard compound interest typically compounds at discrete intervals (annually, monthly, etc.).

Q2: What are typical applications in the UK?
A: Used for projecting investment growth, property values, inflation calculations, and business revenue forecasting.

Q3: How accurate are these projections?
A: They assume a constant growth rate, which rarely happens in reality. Use as an estimate rather than exact prediction.

Q4: Can I calculate negative growth?
A: Yes, enter a negative rate for exponential decay calculations (e.g., depreciation).

Q5: What's the Rule of 72?
A: A quick estimation: divide 72 by the growth rate to find doubling time (e.g., 7.2% growth doubles in ~10 years).
