About This Calculator
This compound interest calculator uses the formula A = P(1 + r/n)^(nt) combined with regular contribution calculations to project your investment growth. Compound interest means you earn interest on both your original investment and on previously earned interest, which can significantly accelerate wealth building over long time periods. The more frequently interest compounds, the faster your money grows.
