What Is FREE TOOLS Exponential Growth Calculator?
An Exponential Growth Calculator is a free online mathematics tool that calculates how quickly a quantity increases over time when it grows at a constant percentage or proportional rate.
It is commonly used in mathematics, finance, investing, economics, business, science, and population studies.
Exponential Growth Formula
The basic exponential growth formula is:
y = a(1 + r)ᵗ
Where:
- y = final amount
- a = initial amount
- r = growth rate expressed as a decimal
- t = time period
For continuous growth, the formula is:
y = aeᵏᵗ
Where k represents the continuous growth rate.
Example
Suppose you invest $1,000 and it grows by 8% per year.
Using:
y = 1,000(1 + 0.08)ᵗ
After 5 years:
y = 1,000(1.08)⁵ ≈ $1,469.33
So, the investment would grow to approximately $1,469.33 after five years, assuming the 8% growth rate remains constant and ignoring fees and taxes.
