What is an index fund, in plain English?
An index fund is a single thing you buy that holds every company in a published list, in proportion, with nobody choosing which ones look promising.
How much do investment fees actually cost me?
A 1% annual fee instead of 0.05% can quietly take roughly a fifth of your final balance over thirty years, because the fee compounds against you every year the money is invested.

Clear anything charging more than roughly 7–8% before investing, because paying off a debt is a guaranteed return at that rate and no investment offers a guaranteed anything.

Compounding multiplies rather than adds, and the number of years the money has been growing is the exponent — which makes time the input with the steepest effect on the final figure, ahead of the amount.
