Determining the Right Percentage of Income for Your Mortgage

Embarking on the journey to homeownership requires careful financial planning, especially when deciding how much of your income should be dedicated to your mortgage. Allocating an appropriate portion of your earnings ensures that you can comfortably manage your housing expenses without compromising other financial obligations. Several established guidelines can assist in making this determination.

The 28% Rule

A widely accepted standard, the 28% rule, suggests that your monthly mortgage payment—including principal, interest, taxes, and insurance (PITI)—should not exceed 28% of your gross monthly income. This guideline helps maintain a manageable housing expense relative to your earnings.

Example Calculation:

  • Gross Monthly Income: $6,000

  • Maximum Monthly Mortgage Payment: $6,000 × 0.28 = $1,680

By adhering to this rule, you can prevent overextending your budget on housing costs.

The 28/36 Rule

Building upon the 28% rule, the 28/36 rule incorporates your total debt obligations. It advises that while your housing expenses remain at or below 28% of your gross monthly income, your total debt payments—including housing, credit cards, car loans, and other debts—should not exceed 36% of your gross monthly income.

Example Calculation:

  • Gross Monthly Income: $7,000

  • Maximum Monthly Housing Expense: $7,000 × 0.28 = $1,960

  • Maximum Total Monthly Debt Payments: $7,000 × 0.36 = $2,520

This comprehensive approach ensures that your total debt load remains within a manageable range.

The 35/45 Rule

For those seeking more flexibility, the 35/45 rule offers an alternative perspective by considering both gross and net income. It suggests that your total debt payments should not exceed 35% of your gross income and 45% of your net (after-tax) income.

Example Calculation:

  • Gross Monthly Income: $8,000

  • Net Monthly Income: $6,000

  • Maximum Total Debt Payments (Gross): $8,000 × 0.35 = $2,800

  • Maximum Total Debt Payments (Net): $6,000 × 0.45 = $2,700

This rule accommodates variations in tax liabilities and provides a broader framework for budgeting.

The 25% Rule

For a more conservative approach, the 25% rule recommends that your housing costs should not exceed 25% of your after-tax income. This strategy emphasizes financial flexibility and the ability to manage unexpected expenses.

Example Calculation:

  • Net Monthly Income: $5,000

  • Maximum Monthly Housing Expense: $5,000 × 0.25 = $1,250

By limiting housing expenses to this percentage, you can allocate more funds toward savings, investments, and other financial goals.

Personalizing Your Mortgage Budget

While these guidelines provide a solid foundation, it's essential to tailor your mortgage budget to your unique financial situation. Consider factors such as:

  • Current Debts: Assess all existing financial obligations.

  • Lifestyle Preferences: Account for discretionary spending and lifestyle choices.

  • Financial Goals: Align your mortgage budget with long-term objectives like retirement savings or education funds.

Utilizing online mortgage affordability calculators can offer personalized insights into what you can afford.

Determining the appropriate percentage of your income to allocate toward your mortgage is a critical step in achieving sustainable homeownership. By applying these guidelines and considering your personal financial circumstances, you can make informed decisions that support long-term financial health.
