The compound interest formula is:

Where:
A is the amount you will have.
P is the money you are investing.
r: is the interest rate (in decimals)
n: number of times the interest is compounded per year
t: time (in years)
The first thing is converting the rate from percentage to decimal:

Since the interest is compounded every month and a year has 12 months n=12.
Now we can replace the values in our formula:

We can simplify the exponents to get:

Finally, we can use our calculator to get 288463.33
After 18 your balance in your bank account will be $288463.33
One of the steps in solving this problem is this one:
As we know as shown above, the joournal entry for 2014 and 2015 will include the investment balance, increases and decreases to equity and intra-entity profits realized and deferred. Also the balance of the acquisition needs to be calculated.
Calculation of the book value of the purchase made as the book value of Company K times percent purchased:
400,000 * 0.40 = 160,000
Then, calculate the difference in the acquisition and the book value of the purchase:
210,000 - 160,000 = 50,000
