How We Calculate Affordability

Income

We start with your monthly gross income and apply standard debt-to-income ratios to determine your maximum affordable monthly payment.

Debt-to-Income

Lenders typically use a 28/36 rule: 28% of income for housing, 36% for total debt.

Loan Details

We factor in the interest rate, loan term, property taxes, and insurance to calculate the total monthly payment.

Understanding Debt-to-Income Ratio

Your debt-to-income (DTI) ratio is a key factor lenders use to determine how much you can borrow. It compares your monthly debt payments to your monthly gross income.

A lower DTI ratio indicates you have more disposable income to cover mortgage payments. Most lenders prefer a DTI ratio of 36% or less.

DTI Categories

Excellent: <20%

Low debt burden

Good: 20-36%

Manageable debt

Fair: 37-43%

Higher risk

Poor: >43%

May need to reduce debt

Frequently Asked Questions

What is the 28/36 rule?

The 28/36 rule is a guideline lenders use to assess mortgage affordability. It states that your housing expenses should not exceed 28% of your gross monthly income, and your total debt payments should not exceed 36%.

What counts as monthly debt?

Monthly debt includes credit card payments, car loans, student loans, personal loans, child support, and any other recurring monthly payments. It does not include utilities, groceries, or other living expenses.

How does my credit score affect affordability?

A higher credit score can qualify you for a lower interest rate, which reduces your monthly payment and increases the amount you can afford. A lower credit score may result in a higher interest rate or may limit the amount you can borrow.

Should I include PMI in my calculations?

Yes, if your down payment is less than 20%, you should include PMI in your monthly payment calculation. Our calculator automatically includes PMI when needed.

What is a good debt-to-income ratio?

A DTI ratio of 36% or lower is considered good. Lenders typically prefer ratios below 43%, though some government-backed loans allow higher ratios with compensating factors.
