Compound Interest Calculator

Compound interest is interest calculated on the initial principal and also on the accumulated interest from previous periods. Einstein reportedly called it "the eighth wonder of the world."

Formula:

A = P(1 + r/n)^(nt)

• A = Final amount
• P = Principal (initial investment)
• r = Annual interest rate (decimal)
• n = Compounding frequency per year
• t = Time in years
