Calculate absolute, total and annualized return on investment.

How ROI is calculated

Absolute return is the simple difference between final and initial value. Annualized return compounds that change over the years of the investment.

Why annualized matters

Two investments with the same total return can have very different annualized rates depending on how long the money was invested. The annualized number makes them comparable.
