Instructions are listed below.

Explanation:

Giving the following information:

Your goal is to have $15,000 in your bank account by the end of four years. The interest rate remains constant at 4% and you want to make annual identical deposits.

End of the year:

To calculate the annual deposit, we need to use the following formula:

FV = {A*[ (1+i) ^n-1]}/i

A = annual deposit

Isolating A:

A = (FV*i) / {[ (1+i) ^n]-1}

A = (15,000*0.04) / [ (1.04^4) - 1] = $3,532.35

Beginning of the year:

A = { (FV*i) / {[ (1+i) ^n] - 1]} / (1+i)

A = 3,532.35 / 1.04 = $3,396.49

The difference resides in the interest compounded. At the beginning of the year the interest compound for one more period.
