What rate of return means
Rate of return is the total gain or loss as a percent. It is measured over your holding period. So it shows how much the investment grew. A gain shows as a positive percent. So a loss shows as a negative one. It is shown as a percent.
How it is calculated
The tool takes your two values. It subtracts the start from the end. It then divides by the starting value. So that ratio becomes a percent. The result is your rate of return. The calculator handles this for you.
What the result tells you
The result shows your rate of return. Ten thousand growing to thirteen thousand is a thirty percent total return. A bigger gain shows a higher percent. A loss shows a negative one. So it shows how the investment did. It is a clean, clear result.
The initial value
The initial value is what you put in. It is the cost of the investment. Use the amount you first paid. So the return is measured from there. A different base changes the percent. So the start sets the scale. Enter your starting value.
The final value
The final value is what it is worth now. It is the value at the close. Use the current or final amount. So the tool can find the change. A higher final value lifts the return. So the end drives the result. Enter your ending value.
Total return versus annual return
This tool shows the total return over the period. It is not a yearly rate. A thirty percent gain over ten years is modest each year. So the time held matters a lot. A short gain beats a long one. So always note the period. Read the total with the years in mind.
