About this calculator
Exponential growth: a quantity that grows at a rate proportional to its current size. Continuous form (e^kt) for processes with constant per-unit-time growth rate; discrete form ((1+r)^t) for periodic compounding. The doubling time follows from solving 2 = e^kt or 2 = (1+r)^t.
