What Is The Debt-To-Income Ratio (DTI)?
Measuring your existing debts against your existing income is one part of a lender’s required assessment of your ability to repay a loan.
Like the video says: debts are existing financial commitments; a car payment is a debt a grocery bill is not.
To calculate your debt-to-income ratio add up your monthly debt payments and divide them by your GROSS monthly income. (Gross income is generally the amount of money you earn BEFORE taxes and other deductions.) The Federally-established debt-to-income target is a maximum of 43% for Qualified Mortgages.
