Rate of Return Calculator Formula

RoR=[(Vfinal+IVinitial)1t1]×100%\text{RoR} = \left[ \left( \frac{V_{\text{final}} + I}{V_{\text{initial}}} \right)^{\frac{1}{t}} - 1 \right] \times 100\%

Rate of return measures the annualized compound financial gain or loss realized over an investment holding period, incorporating capital price changes and income.
