Frequently asked questions
Simple or compound interest?
Savings accounts usually compound, so interest earns interest over time.
How big should my emergency fund be?
Three to six months of essential expenses is a common target.
Does the rate really matter?
Yes — the gap between a low and high rate compounds into real money.
