Expert Tip

Minimizing ETF expense ratios can preserve thousands of dollars in investment capital over decades of compounding.

How this Calculator Works

This calculator projects the total dollar cost of expense ratios and management fees on an Exchange-Traded Fund (ETF) over your holding period. Even small differences in fees compound over decades, causing significant differences in net wealth. Investors use it to choose low-cost funds.

Formula & Methodology

Gross Future Value = Principal * (1 + r)^t + PMT * [ ((1 + r)^t - 1) / r ] Net Future Value = Principal * (1 + r_net)^t + PMT * [ ((1 + r_net)^t - 1) / r_net ] Total Fee Cost = Gross Future Value - Net Future Value - r is the expected annual return rate. - r_net is the net annual return (r - Expense Ratio / 100). - t is the investment horizon in years.

Step-by-Step Calculation Example

Here is a step-by-step example showing how the calculations are performed:

You invest $10,000 for 10 years at a 7% gross return rate. The ETF charges an expense ratio of 0.50% (net return = 6.50%). 1. Calculate future value without fees: $10,000 * (1.07)^10 = $19,671.51. 2. Calculate net future value with fees: $10,000 * (1.065)^10 = $18,771.37. 3. Subtract net from gross value: $19,671.51 - $18,771.37 = $900.14. Result: The ETF expense ratio costs you $900.14 in fees and lost compound growth over 10 years.

FAQ

How does compounding frequency impact investment returns?
More frequent compounding (e.g. monthly or daily vs. annually) generates higher effective annual yields (APY) because interest is calculated on accumulated interest earlier in the period.
What is the difference between Sharpe Ratio and Sortino Ratio?
The Sharpe ratio divides excess return by total standard deviation (both upside and downside volatility), whereas the Sortino ratio divides excess return by downside deviation only.
Should investment calculators replace professional wealth management?
No. Investment calculators model financial mathematics under assumed growth rates. Actual market performance fluctuates, so consult a licensed financial planner (CFP) or RIA for personalized advice.
