# Compounded daily effective interest rate

For example, for a loan at a stated interest rate of 30%, compounded monthly, the effective annual interest rate would be 34.48%. Banks will typically advertise the stated interest rate of 30% rather than the effective interest rate of 34.48%. The daily interest rate is about 0.005 percent (2 divided by 365). If you have an initial balance of \$10 million on the first day of the cycle, the interest earned is \$500.00 (0.005 percent times \$10 million). The next day you'll multiply the new balance of \$10,000,500 times the daily interest rate to get The Effective Annual Rate (EAR) is the rate of interest actually earned on an investment or paid on a loan as a result of compounding the interest over a given period of time. It is higher than the nominal rate and used to calculate annual interest with different compounding periods - weekly, monthly, yearly, etc At 7.18% compounded 52 times per year the effective annual rate calculated is multiplying by 100 to convert to a percentage and rounding to 3 decimal places I = 7.439% So based on nominal interest rate and the compounding per year, the effective rate is essentially the same for both loans. With 10%, the continuously compounded effective annual interest rate is 10.517%. The continuous rate is calculated by raising the number "e" (approximately equal to 2.71828) to the power of the interest rate and subtracting one. It this example, it would be 2.171828 ^ (0.1) - 1. To calculate daily compounding interest, divide the annual interest rate by 365 to calculate the daily rate. Add 1 and raise the result to the number of days interest accrues. Subtract 1 from the result and multiply by the initial balance to calculate the interest earned. The effective annual interest rate is equal to 1 plus the nominal interest rate in percent divided by the number of compounding persiods per year n, to the power of n, minus 1. Effective Rate = (1 + Nominal Rate / n ) n - 1

Example. What is the effective period interest rate for nominal annual interest rate of 5% compounded monthly? Solution: Effective Period Rate = 5% / 12months  The Effective Annual Rate (EAR) is the interest rate that is adjusted for compounding over a given period. Interest rate adjusted for compounding over a given period Weekly = 52 compounding periods; Daily = 365 compounding periods  The nominal rate is the interest rate as stated, usually compounded more than once per year. The effective rate (or effective annual rate) is a rate that,  The same loan compounded daily would yield: r = (1 + .05/365)^365 - 1, or r = 5.13 percent. Note that the effective interest rate will always be greater than the

### Example. What is the effective period interest rate for nominal annual interest rate of 5% compounded monthly? Solution: Effective Period Rate = 5% / 12months

CD Rate Chart. Interest is compounded daily. Minimum Deposit: If you have no other ABC accounts, a minimum of \$10,000 (for example) is required to open a Certificate of Deposit. Persons who have ABC accounts may open a Certificate of Deposit with a minimum of \$2,500 (depending on the bank). Annual Percentage Yields (APYs) assume interest and The value exceeding 100 in case 'a' is the effective interest rate when compounding is semi-annual. Hence 5.063 is the effective interest rate for semi-annual, 5.094 for quarterly, 5.116 for monthly, and 5.127 for daily compounding. Just memorise in the form of a theorem. 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
