How to calculate
Compare a projected investment balance before and after an annual expense ratio.
Balance before fund fee = initial*(1+gross/100)^years; Balance after stated fee = initial*(1+(gross-fee)/100)^years; Estimated fee impact = initial*(1+gross/100)^years-initial*(1+(gross-fee)/100)^years
Worked example
Initial investment: 10000; Gross annual return (%): 7; Annual expense ratio (%): 1; Years: 20.
Balance before fund fee: 38,696.84 ; Balance after stated fee: 32,071.35 ; Estimated fee impact: 6,625.49 .
