## Double rate interest

In wanting to know of any capital, at a given yearly percentage, in how many years it will double adding the interest to the capital, keep as a rule [the number] 72 in  Clay tablets from circa 2000 BCE include the exercise "Given an interest rate of 1/ 60 per month (no compounding), come the doubling time." This yields an annual   The rule says that to find the number of years required to double your money at a given interest rate, you just divide the interest rate into 72. For example, if you

To save you a little time, here are some common interest rates, plus the amount of time it will take for you to double your investment with each interest rate: 1% - 72 years 2% - 36 years 3% - 24 years 4% - 18 years 5% - 14 years 6% - 12 years 7% - 10.3 years 8% - 9.0 years 9% - 8.0 years 10% - 7.2 years 11% - 6.5 years 12% - 6.0 years Use the Rule of 72 to estimate how long it will take to double an investment at a given interest rate. Divide 72 by the interest rate to see how long it will take to double your money on an investment. Alternatively you can calculate what interest rate you need to double your investment within a certain time period. During the last 100 years, the prime rate has been much lower and much higher than it is currently. For instance, in 1949 it was 2 percent. By 1968 the prime rate had climbed to 6.31 and in 1969 it jumped to 7.95 percent. In 1981 it reached its highest point — 18.87 percent — since 1949. Where principal is the balance in savings, rate is the interest rate, and t is the number of times the interest is compounded during a year. According to the book if you type in 4.25 as the interest rate and 12 as the number of times compounded with the principal as 1000.00 then you should get 43.34 as interest and the total amount should be 1043.34.

The rates and terms for an EE bond depend largely on when the bond was issued: Double Your Money: The Rule of 72. The Rule of 72 is a quick and simple technique for estimating one of two things: the time it takes for a single amount of money to double with a known interest rate, or; the rate of interest you need to earn for an amount to double within a known time period. The rule says that to find the number of years required to double your money at a given interest rate, you just divide the interest rate into 72. For example, if you want to know how long it will take to double your money at eight percent interest, divide 8 into 72 and get 9 years.

### So I am trying to learn C++ for a college course and I have to write a program which uses this formula: Amount = Principal * (1 + Rate/T)^T Where principal is the balance in savings, rate is the interest rate, and t is the number of times the interest is compounded during a year.

Let's say you invest \$100 (the principal) at a yearly interest rate of 5 percent. Multiplying the principal by the interest rate gives you an interest payment of \$5. This is your simple interest. The next year and each year thereafter, you will be paid \$5 of interest on the principal of \$100. The doubling time for simple interest is simply 1 divided by the periodic rate. The formula for doubling time with simple interest is used to calculate how long it would take to double the balance on an interesting bearing account that has simple interest. Simple interest is interest earned based solely on the principle.
