Yes, that's an accurate number.
It is called the rule of 72. You take the interest rate you will be receiving and divide that number into 72. the answer will be the number of years it will take you to double your money at that interest rate.
Simple interest is the interest you earn on your principal, IE the amount of your original investment. For example, you put 1000 dollars in a saving account paying 3% per annum. At the end of the year you will have earned 30 dollars on that one thousand dollars. If you leave the principal and interest in the account for another year you will earn another 30.00 on your original 1000 dollars plus .90 interest. on the first 30.00 dollars interest. This gives you a total of 1060.90 in your second year. In each succeeding year you will earn interest on your interest plus interest on your original principal which, if left alone will add up to a substantial some given the power of compound interest. One caveat, compound interest is a double edged sword. If you have a loan and fail to make your monthly payments on time, compound interest will gut you financially.
In fact compound interest is exciting if you're lending but dangerous if you're borrowing as the interest is added to the principal and itself attracts interest. To calculate compound interest use the Rule of 42. Divide the rate of interest into the number 42 and the answer is the number of periods - usually years when dealing with annual interest - for the principal, i.e. the sum borrowed and therefore the amount to be paid back, to double in value. Example: borrow $1000 at 6% p.a., pay nothing each year and you will owe $2000 at the end of 7 years. Conversely, use the rule of 42 to find out the rate of depreciation. If your $10,000 car depreciates at 6% a year then it will be worth $5000 at the end of 7 years.
twofold doubleheader
Use the "rule of 72"...simply put, using compound interest you take the number 72 and divide it by the interest rate. Thus, at 5% the time to double is 14.4 years. This formula can be used for calculating a "double" for any interest rate using the same mathematical procedure.
About 8 years to double (divide 70 by the interest rate), and presumably another 8 years to double again? This supposes compound interest. For simple interest, 11 years to double and 33 to quadruple.
There is a quick and dirty way to convert simple interest to compound interest. First you need to know how long it will take to double your initial number. For Example: Let's say that you find an investment that pays 10% simple interest. That means it takes 10 years to double your investment. We then use the rule of 72 to determine the rate of compound return will give an equivalent time. The rule of 72 says that you divide either the rate of return or the time period into 72 to come up with the other. So, in this example we want to know what interest rate would double our money in 10 years. divide 72 by 10 = 7.2 This means that 7.2% compound interest is equal to 10% simple interest.
Yes, that's an accurate number.
Because they're loaning the money in those deposits at double or more the interest rates that they're paying the depositors.
I think there called "compound eyes" but you better double check
An example of a compound with a double covalent bond is ethene (C2H4), while an example of a compound with a triple covalent bond is nitrogen gas (N2). Double bonds involve the sharing of two pairs of electrons between atoms, while triple bonds involve the sharing of three pairs of electrons.
It is called the rule of 72. You take the interest rate you will be receiving and divide that number into 72. the answer will be the number of years it will take you to double your money at that interest rate.
Approximately 7 years. The general rule is to divide 70 by the interest rate to get an approximation of how long it will take to double. If the interest is compounded annual you will have $194.88 after 7 years, and $214.37 after 8 years. Though if interest is compounded more regularly (ie. monthly or daily) this will grow at a slightly faster rate.
Its a compound word.
A double displacement reaction has two compound reactants and two compound products. In this type of reaction, the positive and negative ions in the reactants switch partners to form new compounds.
