Mortgage To Income Ratio Calculator

Buying a home is one of the biggest financial decisions most people make. Understanding how much you can comfortably afford is crucial before committing to a mortgage. The Mortgage to Income Ratio Calculator is an easy-to-use tool that helps you determine whether your current or planned mortgage fits within a safe and sustainable budget. By comparing your monthly income to your housing and debt expenses, it provides a clear picture of your financial health and affordability status.

What Is a Mortgage-to-Income Ratio?

Your mortgage-to-income ratio (MTI) measures how much of your monthly income goes toward your housing costs — including mortgage payments, property taxes, and insurance. Lenders often use this ratio to evaluate your ability to repay a loan. A lower MTI generally indicates better affordability and financial stability.

Typically, mortgage lenders prefer:

• Mortgage-to-income ratio: below 28%
• Total debt-to-income ratio (DTI): below 36%

These benchmarks ensure that you can cover other living expenses comfortably while maintaining your mortgage.

Practical Example

Let’s consider a sample scenario:

• Monthly Income: $4,000
• Mortgage Payment: $1,200
• Other Debt Payments: $300
• Property Tax & Insurance: $250

Step 1: Add mortgage and property tax = $1,200 + $250 = $1,450 (housing cost)
Step 2: Mortgage-to-income ratio = ($1,450 ÷ $4,000) × 100 = 36.25%
Step 3: Total debt = $1,200 + $300 + $250 = $1,750
Step 4: Debt-to-income ratio = ($1,750 ÷ $4,000) × 100 = 43.75%

Result: The calculator would show an Affordability Status: Too High, meaning the mortgage consumes too much of your income. You might want to lower your target loan or increase your income to reach an ideal ratio.

Your MTI ratio directly affects how much a lender is willing to loan you. Keeping it within a safe range ensures:
