Frequently Asked Questions
Compare Fund 1 vs Fund 2 expense ratios side by side. Our calculator turns small percentage fees into real dollar amounts, so you invest with confidence.
A: It calculates the total dollar amount you lose to fund fees over your chosen time horizon. You enter your initial investment, annual contribution, expected annual return, and duration. The tool then compounds two different expense ratios side by side, showing you the final balance difference in real dollars — not just percentages.
A: Even a small gap adds up fast. On a $10,000 investment with $5,000 added yearly over 30 years, a 0.10% fund can finish tens of thousands of dollars ahead of a 0.75% fund. The compounding effect means fees don't just cost you the fee itself — they cost you the growth that fee would have earned.
A: A 0.5 percentage point gap sounds tiny, but it isn't linear over time. Fees are charged every year on your full balance, so the drag compounds alongside your gains. Over 20-30 years, this gap routinely costs investors five to six figures in lost final balance — money that never gets a chance to grow.
A: The damage is small in year one but accelerates fast after year 10-15, once your balance is large enough for the fee percentage to represent real money. Run different duration values in the calculator — most users are surprised how much the gap widens between the 15-year mark and the 30-year mark.
A: Expense ratios can change year to year — fund providers occasionally raise or lower them. This calculator assumes a fixed rate for simplicity, giving you a clean baseline comparison. Check your fund's latest prospectus annually and rerun the numbers if the ratio shifts.
A: It comes down to compound interest working against you. Every dollar paid in fees is a dollar that stops earning future returns. Over 30 years, that "invisible" 0.65% annual gap can consume more of your wealth than most people's total contributions — which is exactly what this calculator makes visible.
A: Usually, but not automatically. A slightly higher expense ratio can be worth it if the fund delivers meaningfully higher net returns after fees — actively managed funds sometimes claim this. Use the calculator to test: plug in each fund's real return rate, and let the dollar-cost comparison guide your decision instead of the percentage alone.
A: Enter your current savings rate, expected annual return, and target retirement timeline. Then swap the expense ratio between your current fund and a lower-cost alternative. The savings difference shown is money that goes straight toward your FIRE number — often shaving years off your retirement date.
