Why does compounding frequency matter?

More frequent compounding (daily vs. monthly vs. annually) produces a slightly higher return at the same stated rate, since interest starts earning its own interest sooner.

What formula does this use?

A = P × (1 + r/n)^(n×t), where P is principal, r is annual rate, n is compounding periods per year, and t is time in years.
