The "Rule of 72" gives a good approximation of 72/4=18%.
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.
Nine years at 8%
10 years
14.87% per annum, compounded for 5 years would give back very slightly more than double (2.000014).
It is interest
If you have an annual interest rate then is 10.405%
How long it will take for your money to double/divide the annual interest rate into 72.
the number of years it takes for your money to double can be estomated by dividing 72 by the annual percentage interest rate.
Here is the equation: (1 + x/100) to the power 4 = 2 In other words, take the fourth root of 2, subtract one, and - to convert the result to a percentage - multiply it by 100. Note: You won't usually get such a high interest rate.

The number of years it takes for your money to double can be estimated by dividing 72 by the annual percentage interest rate.
The monthly interest on $500,000 will depend on the interest rate at the time the money was borrowed. Interest is usually charged as an annual rate and then broken down into monthly segments.
An annual percentage yield enables one to find out how much interest a set amount of money is earning in interest per year. Many banks and other financial institutions include an interest calculator on their websites.
To calculate interest on a loan, you typically use the formula: Interest = Principal × Rate × Time. The principal is the amount borrowed, the rate is the annual interest rate expressed as a decimal, and time is the duration the money is borrowed for, usually in years. For example, if you borrow $1,000 at a 5% annual interest rate for 3 years, the interest would be $1,000 × 0.05 × 3 = $150. Depending on the type of interest (simple or compound), the calculation may vary slightly.
The money factor formula used to calculate the cost of borrowing money is: Money Factor Annual Interest Rate / 2400.
