Calculate Doubling Time
Result:
The Doubling Time Formula
The doubling time can be calculated using the Rule of 70, which provides a good approximation:
Doubling Time = 70 / Growth Rate (%)
For more precise calculations, we use the natural logarithm:
Td = ln(2) / ln(1 + r)
Where:
- Td = Doubling Time
- r = Growth Rate (as a decimal)
- ln = Natural logarithm
