What you want to ask is the formula for calculating the geometric average rate of return for four years? 4-year geometric average rate of return = (1+r1) x (1+R2) x (1+R3) x (1+R4) to the power of 1+0. Among them, r 1, r2, r3 and r4 are the annual rates of return during the four-year period. According to the query of Penghua Fund Network, the geometric average rate of return is the geometric average rate of return of investment and wealth management products in each period, which generally refers to the annual average actual income under the condition of compound interest every year. It uses compound interest thinking and considers the time value, which can more accurately reflect the real income of investors. So the geometric average rate of return for four years = (1+r1) x (1+R2) x (1+R3) x (1+R4) to the power of 1/4.
