| The ratios are basically your income divided by your liabilities. They determine how much you can afford based on your yearly salary.
Front Ratio is the total mortgage payment, including principal, interest, taxes and insurance as well as any Private Mortgage Insurance and/or Home Owners Association fees divided by your total GROSS income. For example, with a gross income of $4783 per month, a total mortgage payment (PITI) of $976.63 would give you a Front ratio of 28%.
Back Ratio is the total mortgage payment as stated above PLUS all other liabilities such as car payments, credit cards, student loans, etc. divided by your gross income.
