Because different months have different amount of days, the formula varies. If it's monthly, you take your principal (P), times your interest rate (R), divided by 12 months in a year. Thus, P*R/12= monthly interest rate.
Answer edited by Macintoast 6/13/2009: I am not a banker and I don't know the correct answer to your question off hand. I do know that the answer above is overly simplistic and inaccurate because it only gives you the approximate NON-compounded monthly interest rate and does not fully answer the question. The correct answer to the question is a longer formula with variables and parentheses, so you'll recognize it when you see it. Good luck.

you are right that you are not a banker, but you are a wanker.
Suppose the amount invested (or borrowed) is K, Suppose the rate of interest is R% annually, Suppose the amount accrues interest for Y years. Then the interest I is 100*K[(1 + R/100)^Y - 1]
Annual Interest Rate divided by 12= Monthly Interest Rate
Assuming interest is compounded annually, 1000*(1.08)5
I = PRT where I is the interest. P is the principal R is the interest rate per unit of time, expressed as a fraction (5% = 0.05 or 1/20) but not as a percentage, T is the number of time units.
You would have a very tough time, because that isn't the formula to calculate work. (distance) divided by (time) is the formula to calculate speed. The formula to calculate work is: (force) multiplied by (distance).

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.
In calculating for the interest, please use the formula below:I = PRTwhere I stands for InterestP for principalR for rate; andT for time
Annual Interest Rate divided by 12= Monthly Interest Rate
The formula to calculate interest is as follows: Interest = Principal * No. of years * Rate of Interest / 100 So Interest = 10000 * 0.5 * 8 / 100 = 400/- The interest you will receive interest at the end of the 6 month period is Rs. 400/-
if i invested Rs.100 per day for 180 days @ int.5% what would be the total interest & how they calculate
Find the amount of interest added at each compounding interval (also called the periodic rate).Calculate the interest added for the first time interval.Add the interest to the value of the debt security to find the ending value for the period.Use a formula to calculate maturity value.
Normal interest is not calculated over a period of time. It is just the formula to calculate the interests gained. Compound interest is calculated over more time periods such as years.
The formula for the daily compound interest is B=p(1+r over n)NT as an exponent for the nt B= ending balance P= principal amound r= interest rate n= number of compounds per year t= time( in years)
the chemical formula C6H14 has 5 compounds
