Understanding Exponential Growth
Exponential growth happens when a value increases by a fixed percentage over time.
Common examples include:
- Investment growth
- Population increase
- Business revenue growth
- Social media audience growth
- Compound interest
The growth becomes larger over time because each increase is based on the previous total.
Understanding Exponential Decay
Exponential decay occurs when a value decreases by a fixed percentage over time.
Examples include:
- Product depreciation
- Radioactive decay
- Battery discharge
- Declining populations
- Asset value reduction
The value shrinks gradually over multiple periods.
Practical Example 1: Investment Growth
Suppose you invest money in a savings account or investment fund.
Example Details
- Initial Investment: 10,000
- Growth Rate: 7%
- Time Period: 10 years
The calculator estimates the future value of the investment after 10 years.
This helps investors understand long-term financial growth and make better investment decisions.
Practical Example 2: Car Depreciation
Vehicles lose value over time, which is a common example of decay.
Example Details
- Initial Car Value: 25,000
- Depreciation Rate: 15%
- Time Period: 5 years
The calculator shows the estimated value of the car after five years and the total value lost.
This is useful for:
- Car buyers
- Sellers
- Insurance planning
- Financial budgeting
