An investment return is the money you gain on top of what you originally put in. It is usually shown as a percentage of your starting amount. The two main types are simple return and compound return.
Simple return only applies to your original amount. Compound return earns on both your original investment and the returns already added — so your money grows faster as time goes on. This is sometimes called "interest on interest."
The longer you stay invested, the more powerful compounding becomes. That is why starting early often matters more than how much you invest. Even small amounts, given enough time, can grow into large sums through compound growth.
Here are the key formulas this calculator uses:
Key: P = Principal, r = Annual Rate, n = Compounding periods per year, t = Years, FV = Final Value, PV = Present Value.
