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%
