This ETF vs index fund calculator compares the long-term cost and final value of both options, based on their annual fees (TER) and any ETF purchase costs.
Small fee differences add up
A lower TER means more of your return compounds over time instead of being eaten by fees. Enter your investment amount, expected annual return, time horizon, the TER of each option and any ETF purchase fees to see which one wins — and by how much — at the end of the period.
Tax treatment isn’t included here, since it depends heavily on where you invest: in some countries, switching between index funds can defer taxes on gains in a way that switching ETFs cannot, which is worth factoring in separately.
