Calculate compound interest with multiple compounding frequencies: annual, semi-annual, quarterly, monthly, daily, or continuous. Input principal, annual rate, and time to get the future value.
Instructions
Calculate compound interest with various compounding frequencies.
Formulas: Discrete: A = P(1 + r/n)^(nt) Continuous: A = Pe^(rt)
Examples:
ANNUAL COMPOUNDING: £1000 at 5% for 10 years principal=1000, rate=0.05, time=10, frequency="annual" Result: £1628.89
MONTHLY COMPOUNDING: £1000 at 5% for 10 years principal=1000, rate=0.05, time=10, frequency="monthly" Result: £1647.01
CONTINUOUS COMPOUNDING: £1000 at 5% for 10 years principal=1000, rate=0.05, time=10, frequency="continuous" Result: £1648.72
