Compound Interest Calculator
Compound interest grows faster than simple interest because it earns returns on both your original principal and any interest already accumulated. This free compound interest calculator lets you choose daily, monthly, quarterly, or yearly compounding frequency, and instantly shows the interest earned and the final amount for your principal, rate, and time period — useful for comparing savings accounts or estimating investment growth.
