How compounding frequency matters
A 5% rate compounded daily yields 5.1267% APY; compounded monthly it is 5.116%; annually, 5.0%. The difference is small at low rates, but at 20% or higher, daily compounding can add 0.5-1% extra per year. For practical purposes, monthly is the right default for most savings accounts.

Profit margins tell you how much of each dollar of revenue you keep. A 30% net margin means for every $1 you earn, you keep $0.30 after all costs. Margins are the most universal measure of business health.
