Understanding Exponential Growth and Decay
Before using the calculator, it is helpful to understand the difference between growth and decay.
Exponential Growth
Exponential growth happens when a value increases by a fixed percentage over time.
Examples include:
- Savings account interest
- Business revenue growth
- Population increase
- Investment returns
Growth Formula
Final Value=Initial Value×(1+r)t
Where:
- r = growth rate
- t = number of time periods
Exponential Decay
Exponential decay happens when a value decreases by a fixed percentage over time.
Examples include:
- Car depreciation
- Equipment wear
- Radioactive material decay
- Product value reduction
Decay Formula
Final Value=Initial Value×(1−r)t
Where:
- r = decay rate
- t = number of time periods
