Compound interest calculator

Compound interest grows faster than simple interest because earned interest is reinvested. The formula is A = P(1 + r/n)^(nt) — principal × (1 + rate/periods) raised to (periods × time). Small differences in rate or compounding frequency have a large effect over long time horizons.
