The sixth root of 2 (which can be calculated as 2 to the power (1/6)) is 1.1225. If you subtract one, you get 0.1225, so 12.25%.
75 x 7 x 2 = 1050
14.87% per annum, compounded for 5 years would give back very slightly more than double (2.000014).
750 invested for 10 years at 10% pa would be 1,945
Compound Interest = P(1+r/100n)(nt) P = Original Investment r = Interest Rate n = How often the interest is compounded per year t = Number of years Interest = 200(1+6/100)6 = 200(1.06)6 =$283.70
Sometimes. It depends on the interest rate. The rule of 72 will tell you when your investment will double.Example(usage): you invest x dollars at 9% interest per year. 72/9 = 8It will take 8 years for your investment to reach 2x at 9% annual interest.The interest needed to double an investment in 10 years is:72/x=107.2% interestSo if your investment had an annual interest rate of 7.2% it would double in 10 years.
Simple interest: 100/6 ie 16.67%
Rule of seventy two is used to ascertain the period by which an investment would grow by 100%. 72 divided by rate of interest would provide the approximate period by which the investment would become double. As an example, if the rate of interest is 6% per month, the investment would be doubled in ( 72/6) 12 months. Rule of 72 thus is an important tool to know the investment horizon.
Depends on how you invested it and what rate of return that investment delivered.
This would depend on how much interest you are making on your investment. The questions is incomplete because there are so many variables that would change the answer.
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.
It depends on the interest rate. If it was a 10% rate, it would generate $10.00
I would recommend a 401k or a short term investment fund. This is a great investment that is short term and you can gain double on your investment.
Depends on the interest rate, how often interest is being compounded, and the length of time that the investment is left in the bank.
Assuming simple interest, the formula is Interest = Principal x Time x Rate/100, in this case the interest would be 30% of the original investment. If the interest is compounded yearly the the formula is Principal x (1 + Rate/100)^Time so that the new total would be (1 + 0.1)^3 ie 1.331 times the original investment, a total of 33.1% interest.
That would really depend on the investment strategy, are you getting 4% per month, per year or per week (yes they are all possible)? 4% of $150,000 is $6,000. If your interest rate is annual then monthly return would be $500. If your interest rate is monthly then it would be $6,000 and of coarse weekly interest rate of 4% would give you $24,000 monthly. It all comes down to interest rate over what period of time then factored by the month. 6000$
12 years.
