This calculator compares simple interest (principal × rate × time) against compound interest, using A = P(1 + r/n)ⁿᵗ, where n is how many times per year interest compounds (annually, quarterly, monthly, or daily).
It also derives the effective annual yield (APY) — the true annual return once compounding is factored in, which is always slightly higher than the stated nominal rate.
