Exponential Growth Calculator
Calculate discrete exponential growth, total change, and equivalent continuous growth from an initial amount and periodic rate.
Formula
Future value = initial value x (1 + rate)^periods.
About the Exponential Growth Calculator
Calculate discrete exponential growth, total change, and equivalent continuous growth from an initial amount and periodic rate. This tool keeps the requested measurements separate and applies the named method instead of substituting an unrelated general estimate.
How the Exponential Growth Calculator Works
The rate is converted from percent to decimal and compounded once per period; the doubling time uses logarithms when the rate is positive.
Formula
Future value = initial value x (1 + rate)^periods.
The calculation runs in your browser. Values are validated for required ranges, compatible units, and method-specific restrictions before results are displayed.
Required Inputs

Accuracy and Limitations
The model assumes a constant rate and no additions, removals, capacity limit, or random variation.
Keep units consistent, use measurements that represent the actual situation, retain full precision during the calculation, and round only the final answer. Professional decisions may require current official rules, field measurements, laboratory methods, or specialist review.
