Simulate compound investment growth over time with customizable principal, rate, and duration.
Calculates future balance using the compound interest formula: A = P × (1 + r/n)^(n×t), where P is principal, r is the annual rate, n is compounding frequency per year, and t is time in years. The calculator provides complete breakdown of total interest earned versus principal.
A = P × (1 + r / n)^(n × t)You deposit $5,000.00 into a high-yield savings certificate earning 6% annual interest compounded monthly over 3 years.
Interpretation: Compound growth yielded $983.40 in pure interest, outperforming a simple interest return by $83.40 over the same term.
APR ignores intra-year compounding, whereas APY reflects the true effective annual yield generated by compounding.
Using a monthly interest rate with duration expressed in years without conversion leads to astronomical errors.
Compound interest generates returns not only on your original principal but also on previously accumulated interest, creating exponential growth over time.
Monthly compounding applies interest 12 times a year, yielding slightly higher total returns than annual compounding at the same nominal rate.
