Net monthly income: $4,000 • Expected full mortgage payment (PITI): $1,000 • Student loan payment: $250 • Car payment: $300

To determine how much money is left after paying the monthly mortgage, student loan, and car payment, you need to subtract these expenses from the net monthly income.

To calculate the remaining income, perform the following steps:

Step 1: Determine the total monthly expenses by adding up the mortgage payment, student loan payment, and car payment.
Total monthly expenses = Mortgage payment + Student loan payment + Car payment
Total monthly expenses = $1,000 + $250 + $300 = $1,550

Step 2: Subtract the total monthly expenses from the net monthly income to find the remaining income.
Remaining income = Net monthly income - Total monthly expenses
Remaining income = $4,000 - $1,550 = $2,450

Therefore, after paying the monthly mortgage, student loan, and car payment, you would have $2,450 remaining.
