Many homebuyers struggle to create a realistic budget. They often ask, “What percentage of my income should go to housing?” For decades, experts recommended the 30% rule as a guideline.

This guide by Brickfront Properties and Construction explains the rule and its modern alternatives. It helps homebuyers in Maryland and beyond feel confident in their financial decisions.

What is the 30% Rule for Housing Costs?

The 30% rule suggests your housing costs should not exceed 30% of your gross monthly income. Gross income is your total pay before taxes or deductions. This guideline helps ensure you have money for other life expenses. Lenders call this your housing-to-income ratio.

Your total housing cost, or PITI, includes:

• Principal: The loan amount you pay down.
• Interest: The cost of borrowing the money.
• Taxes: Your annual property taxes.
• Insurance: Your homeowners insurance premium.

Where Did the 30% Rule Originate?

The U.S. government created this standard with the National Housing Act of 1969. Initially, it capped public housing rent at 25% of a tenant’s income. Lawmakers later raised this limit to 30% in the early 1980s. It then became a popular benchmark for all renters and homebuyers.

How Do I Calculate My 30% Housing Budget?

You can calculate your maximum housing budget in two simple steps.

1. Find your gross monthly income. If your annual salary is $72,000, divide it by 12. Your gross monthly income is $6,000.
2. Multiply your gross monthly income by 0.30. This finds 30% of your income. Example: $6,000 (gross monthly income) x 0.30 = $1,800

This calculation shows a maximum housing budget of $1,800 per month.

Is the 30% Rule Still Relevant in 2025?

The 30% rule offers a good starting point, not a perfect solution. Today’s financial landscape has changed significantly since the 1980s. Here is why the rule may not be the best fit for you.

• It ignores modern debt. The rule does not factor in student loans or high childcare costs.
• It misses your full financial picture. It overlooks savings, lifestyle, and other personal debts.
• Location impacts affordability. In high-cost areas like parts of Maryland, this rule can be unrealistic.
• It doesn’t scale for high earners. High-income households can often comfortably exceed 30%.

What Are Better Alternatives to the 30% Rule?

Financial experts have developed more comprehensive guidelines. Here are two popular alternatives for budgeting.

The 28/36 Rule

Lenders often use this rule for mortgage qualification. It provides two debt-to-income (DTI) ratio limits.

• Your PITI should not exceed 28% of your gross monthly income.
• Your total debt should not exceed 36% of your gross monthly income. Total debt includes PITI plus car loans, credit cards, and student loans.

The 50/30/20 Budget Rule

This popular rule divides your after-tax income into three spending categories.

• 50% for Needs: Housing, utilities, groceries, and transportation.
• 30% for Wants: Hobbies, dining out, and vacations.
• 20% for Savings & Debt: Emergency funds, retirement, and extra debt payments.
