The simple interest rate of a number is represented by the following formula:
i = (T / P) - 1
Where:
i = interest rate
T = total of all payments
P = principal amount
For example, what is the interest rate if I borrowed $500 and paid back $50 per month for a year?
T = $50/month * 12 months = $600
P = $500
i = (600 / 500) -1
i = 1.2 - 1 = 0.2 = 20%
The simple interest rate is 20%.
To calculate CD interest rate, all you have to do is to just multiply the principal amount you have invested in CD with interest rate. If u want to calculate for the monthly interest then divide the resultant with 12.
Annual Interest Rate divided by 12= Monthly Interest Rate

To calculate the daily interest rate for a financial investment, divide the annual interest rate by 365 (the number of days in a year). This will give you the daily interest rate.
To calculate the monthly interest rate from an annual interest rate, divide the annual rate by 12. This will give you the monthly interest rate.
To calculate the principal and interest payment for a loan, you can use the formula: Payment Principal x (Interest Rate / 12) / (1 - (1 Interest Rate / 12)(-Number of Payments)). This formula takes into account the loan amount (principal), the interest rate, and the number of payments.
The formula used to calculate your interest is the principle balance, multiplied by the monthly interest rate. Then you mulitply that by the number of months in which you last paid interest.
To calculate interest on treasury bills, you multiply the face value of the bill by the interest rate and the number of days the bill is held, then divide by 365.
Multiply the monthly interest rate by the number of months is a year to calculate the annual interest rate: 2% x 12mo = 24%
To calculate CD interest rate, all you have to do is to just multiply the principal amount you have invested in CD with interest rate. If u want to calculate for the monthly interest then divide the resultant with 12.
To calculate the monthly interest rate on a loan or investment, divide the annual interest rate by 12. This will give you the monthly interest rate that is applied to the loan or investment.
Annual Interest Rate divided by 12= Monthly Interest Rate
To calculate the monthly credit card payment, you can use the formula: Payment (Balance x (Interest Rate/12)) / (1 - (1 Interest Rate/12)-Number of Months). This formula takes into account the balance on the card, the interest rate, and the number of months you want to pay off the balance.
To calculate an interest (as money), multiply the capital, times the interest rate (divided by 100, if it is expressed in percent), times the number of periods. The above assumes simple interest; compound interest is a bit more complicated.
To calculate the real interest rate, subtract the inflation rate from the nominal interest rate. The real interest rate reflects the true purchasing power of the money invested or borrowed after adjusting for inflation.
