Compound interest: Frequently-asked questionsWhat is compound interest?Compound interest is the total amount of interest earned over a period of time, taking into account both the interest on the money you invest (this is called simple interest) and the interest earned or charged on the interest you've previously earned. What is the compound interest formula?The compound interest formula is: A = P (1 + r/n)nt The compound interest formula solves for the future value of your investment (A). The variables are: P – the principal (the amount of money you start with); r – the annual nominal interest rate before compounding; t – time, in years; and n – the number of compounding periods in each year (for example, 365 for daily, 12 for monthly, etc.). What's the difference between compound interest and simple interest?Compound interest takes into account both interest on the principal balance and interest on previously-earned interest. Simple interest refers only to interest earned on the principal balance; interest earned on interest is not taken into account. To see how compound interest differs from simple interest, use our simple interest vs compound interest calculator. How does compound interest work?Compound interest has dramatic positive effects on savings and investments. Compound interest occurs when interest is added to the original deposit – or principal – which results in interest earning interest. Financial institutions often offer compound interest on deposits, compounding on a regular basis – usually monthly or annually. The compounding of interest grows your investment without any further deposits, although you may certainly choose to make more deposits over time – increasing efficacy of compound interest.

How do you find the accumulated value of an investment?Calculate Accrued Amount (Future Value FV) using A = P(1 + r/n)^nt. In this example we start with a principal investment of 10,000 at a rate of 3% compounded quarterly (4 times a year) for 5 years. If you paste this correctly you should see the answer Accrued Amount (FV) = 11,611.84 in cell B1.
What is the formula for accumulated amount?For the special case of an initial principal of 1 unit, we denote the accumulated amount at time t by a(t), which is called the accumulation function. Thus, if the initial principal is A(0) = k, then A(t) = k × a(t).
How do you calculate accumulated future value?How do I calculate future value? You can calculate future value with compound interest using this formula: future value = present value x (1 + interest rate)n. To calculate future value with simple interest, use this formula: future value = present value x [1 + (interest rate x time)].
