Frequently Asked Questions
What is a free online Compound Interest Calculator?
A free online Compound Interest Calculator is a web-based tool that helps you determine the future value of an investment or the total amount owed on a loan by calculating interest that is added to the principal over time. It uses the principal, interest rate, time, and compounding frequency.
How does compound interest work?
Compound interest is 'interest on interest'. It's calculated on the initial principal and also on all the accumulated interest from previous periods. This leads to exponential growth over time, making it powerful for investments.
What is the formula for compound interest?
The compound interest formula is: A = P(1 + r/n)^(nt), where A is the future value of the investment/loan, P is the principal amount, r is the annual interest rate (as a decimal), n is the number of times that interest is compounded per year, and t is the number of years the money is invested/borrowed for.
Can I use this calculator for both investments and loans?
Yes, absolutely. This versatile tool can be used to calculate how much your savings or investments will grow (future value) due to compound interest, and also to estimate the total amount you'll repay on a loan including compound interest.
What is compounding frequency and why does it matter?
Compounding frequency is how often interest is calculated and added back to the principal within a year (e.g., monthly, quarterly, annually). The more frequently interest is compounded, the faster your investment grows or your loan amount increases, as you start earning interest on the newly added interest sooner.
Is this compound interest calculator completely free?
Yes! Our Compound Interest Calculator is 100% free to use. You don't need to register, sign in, or pay anything to perform unlimited calculations.
Is my financial data safe when using this tool?
