How Much Home Can I Afford? A Simple Step-by-Step Guide

Step 1: Calculate Your Gross Monthly Income

Gross income is your income before taxes and other deductions.

If You're Paid Hourly

Use this formula:

Hourly Wage × Hours Worked Per Week × 52 ÷ 12

Example:

$25 per hour × 40 hours per week = $1,000

$1,000 × 52 weeks = $52,000 per year

$52,000 ÷ 12 = $4,333 Gross Monthly Income

If You're Paid Weekly

Use this formula:

Weekly Salary × 52 ÷ 12

Example:

$1,200 per week × 52 = $62,400 per year

$62,400 ÷ 12 = $5,200 Gross Monthly Income

If You're Paid Bi-Weekly

Use this formula:

Bi-Weekly Salary × 26 ÷ 12

Example:

$2,000 every two weeks × 26 = $52,000 per year

$52,000 ÷ 12 = $4,333 Gross Monthly Income

Step 2: Estimate Your Maximum Housing Payment

Different mortgage programs have different debt-to-income guidelines.

The "front-end ratio" refers to the percentage of your gross monthly income that may be used toward housing expenses.

Housing expenses typically include:

• Principal and interest
• Property taxes
• Homeowners insurance
• Mortgage insurance (if applicable)
• HOA dues (if applicable)

FHA Loans

Typical Front-End Ratio: 31%

Formula:

Gross Monthly Income × 31%

Example:

$5,000 × 31% = $1,550

Estimated Maximum Housing Payment: $1,550

USDA Loans

Typical Front-End Ratio: 29%

Formula:

Gross Monthly Income × 29%

Example:

$5,000 × 29% = $1,450

Estimated Maximum Housing Payment: $1,450

Conventional Loans

Typical Front-End Ratio: 28%

Formula:

Gross Monthly Income × 28%

Example:

$5,000 × 28% = $1,400

Estimated Maximum Housing Payment: $1,400

VA Loans

VA loans generally focus more heavily on total debt and residual income than a strict front-end ratio.

For a simple estimate, many buyers use:

Gross Monthly Income × 41%

Example:

$5,000 × 41% = $2,050

However, VA qualification also depends on:

• Existing monthly debts
• Residual income requirements
• Credit profile
• Automated underwriting results

Important Things to Remember

These calculations provide a simple starting point and are not a loan approval.

Your actual purchasing power may be affected by:

• Monthly debts
• Credit score
• Interest rate
• Property taxes
• Homeowners insurance
• HOA fees
• Employment history
• Cash reserves
• Automated underwriting results

In many cases, buyers may qualify for more or less than these simple calculations suggest.
