Divide your annual interest rate by the number of times each year interest compounds on your savings account. This is the periodic interest rate. For example, if your savings account pays 3.36 percent each year but compounds interest monthly, divide 3.36 percent by 12 to find the monthly rate is 0.28 percent.

Calculate your total interest paid. This is done by subtracting your principal from the total value of your payments. To get your total value of payments, multiply your number of payments, "n," by the value of your monthly payment, "m." Then, subtract your principal, "P," from this number.

If an amount of $5,000 is deposited into a savings account at an annual interest rate of 5%, compounded monthly, the value of the investment after 10 years can be calculated as follows... P = 5000. r = 5/100 = 0.05 (decimal).

Keep in mind, if it's an annual rate, then the number of compounding periods per year is one, which means you're dividing the interest rate by one and multiplying the years by one. If compounding occurs quarterly, you would divide the rate by four, and multiply the years by four.

To calculate compound annual growth rate, we divide the value of an investment at the end of the period in question by its value at the beginning of that period, raise the result to the power of one, divide by the number of holding periods, such as years, and subtract one from the subsequent result.

An easy and straightforward way to calculate the amount earned with an annual compound interest is using the formula to increase a number by percentage: =Amount * (1 + %) . In our example, the formula is =A2*(1+$B2) where A2 is your initial deposit and B2 is the annual interest rate.

Compound interest uses a more complicated formula: You must add 1 to the interest rate (for example, a 5 percent interest rate would mean 1 + 0.05 = 1.05) and then raise the total to the power of whatever the number of periods is for repayment.

Total = [ Compound interest for principal ] + [ Future value of a series ] Total = [ P(1+r/n)^(nt) ] + [ PMT × (((1 + r/n)^(nt) - 1) / (r/n)) ] Total = [ 5000 (1 + 0.05 / 12) ^ (12 × 10) ] + [ 100 × (((1 + 0.00416)^(12 × 10) - 1) / (0.00416)) ]

Compound interest is calculated by multiplying the initial principal amount by one plus the annual interest rate raised to the number of compound periods minus one.

Simple Interest = P x I x N I = The interest rate. N = The duration of the loan using the number of periods. Compound interest refers to charges that the borrower must pay not just on the principal amount borrowed, but also on any interest accumulated at that point in time.

To calculate the compound annual growth rate, divide the value of an investment at the end of the period by its value at the beginning of that period. Take that result and raise it to the power of one, divide it by the period length, and then subtract one from that result.

The simple interest formula is I = P x R x T. Compute compound interest using the following formula: A = P(1 + r/n) ^ nt. Assume the amount borrowed, P, is $10,000. The annual interest rate, r, is 0.05, and the number of times interest is compounded in a year, n, is 4.
