Understanding Exponential Decay

What is Exponential Decay?

Exponential decay describes a process where a quantity decreases at a rate proportional to its current value. This creates a characteristic curve that gets steeper at the beginning and flattens out over time.

The Formula

The exponential decay formula is:

A(t) = Aâ‚€(1 - r)áµ—
  • A(t) = Final amount
  • Aâ‚€ = Initial amount
  • r = Decay rate (as a decimal)
  • t = Time periods
