How to Use the Exponential Growth Calculator
- Enter Initial Value (P): Input the starting amount (e.g., 1000). Must be a positive number.
- Enter Growth Rate (r): Input the rate as a decimal per year (e.g., 0.05 for 5%).
- Enter Time (t): Input the number of years (e.g., 10). Must be non-negative.
- Select Compounding Period (n): Choose from the dropdown:
- Annually (1), Semi-annually (2), Quarterly (4), Monthly (12), Daily (365), or Continuous (0) for e-based growth.
- Click "Calculate": The future value (A) appears, along with the formula used and step-by-step breakdown.
Note: All numeric inputs accept decimals. Use consistent units (e.g., rate in decimal, time in years). Errors show if fields are empty or invalid.

Frequently Asked Questions
Exponential growth occurs when the growth rate of a value is proportional to its current value, leading to rapid increase over time.
Continuous compounding uses the formula A = P * e^(rt), while discrete compounding uses A = P * (1 + r/n)^(nt), where n is the number of compounding periods per year.
Yes, you can enter a negative growth rate to model exponential decay, such as radioactive decay or depreciation.
