Im has an annual salary of $96,000. His monthly expenses include a $2,500 mortgage payment, a $250 lease payment, $500 in minimum credit card payments, and a $425 payment on his speed boat. He also receives $1,200 in interest from his savings and other accounts each month. Calculate Jim's DTI (debt-to-income) ratio.

The debt-to income ratio is the ratio between all your expenses and the income that you get.

To calculate the DTI, we will first calculate all the annual expenses as follows:

The monthly expenses are given as follows:

Mortgage payment = $2,500

lease payment = $250

minimum credit card payment = $500

Speed boat payment = $425

monthly expenses = 2500 + 250 + 500 + 425 = $3675

Now, to get his annual expenses, we will multiply the monthly expenses by 12 as follows:

annual expenses = 12*3675 = 44100

Now, we need to get his total annual income as follows:

annual salary = $96,000

monthly interest = $1,200, therefore, annual interest = 12*1200 = $14400

The annual income = 96000 + 14400 = $110400

Finally, we can calculate the DTI ratio by dividing the annual expenses by the annual income as follows:

DTI = (44100) / (110400) = 0.399 = 39.9%
