In this lesson

Expense ratios is part of Funds and ETFs. This preview shows how investment-universe connects to everyday family decisions such as earning, saving, spending choices, goals, approvals, or parent-guided money conversations inside Progress Penguin.

Think about this money choice

Imagine this situation: Fund A: 15% return, 0.2% expense ratio. Fund B: 15% return, 2.0% expense ratio.

How it works

Expense ratio = total annual fund costs ÷ assets. It is deducted daily from the fund's NAV (net asset value) — you never see a direct charge but your returns are reduced by this amount annually. A 2% expense ratio means the fund must outperform a 0.2% fund by 1.8% just to deliver the same net return to you.

Apply it to a real decision

Real-life money moment: Fund A: 15% return, 0.2% expense ratio. Fund B: 15% return, 2.0% expense ratio. On 1000000 in local currency over 20 years, approximate difference in ending wealth? The key lesson is: The expense ratio compounds against you.

Quiz preview

An 'expense ratio' is:

Your bank fee given the circumstances
Your return in practical terms
The fund's annual fee as a percentage
Your tax when planning ahead

Fund A: 15% return, 0.2% expense ratio. Fund B: 15% return, 2.0% expense ratio. On 1000000 in local currency over 20 years, approximate difference in ending wealth?

Fund B is better — higher fees mean better management
200000 in local currency difference — small over 20 years
No difference — fees are deducted separately
Fund A: 1,000,000×(1.148)^20≈17600000 in local currency.
