How to Calculate Your Mortgage Budget (Without Stressing Out)

So, you’re ready to buy a home—but how much house can you actually afford?

This is one of the most important questions you’ll ask in your life, and the answer can shape your future. But don’t worry—it’s not rocket science. In fact, with a few smart tips and tools, you can calculate your mortgage budget like a pro (even if you’re not one).

Let’s break it down in the simplest way possible. 🧮💰

💡 Step 1: Know Your Monthly Income

Before anything else, you need to figure out how much money is coming in every month. This includes:

Your salary (after taxes)
Freelance or side hustle income
Investment income (if any)

Let’s say you bring home $4,000 per month after taxes. That’s your total take-home pay.

💳 Step 2: Calculate Your Monthly Debts

Now subtract all your fixed monthly debts:

Car loans
Credit card payments
Student loans
Personal loans

Example:

Car loan = $350
Credit card = $150
Student loan = $300
Total debt = $800/month

🧠 Step 3: Use the 28/36 Rule

This is a golden rule in the mortgage world.

28% of your income should go toward housing costs (mortgage, taxes, insurance).
36% of your income should go toward total debt (including housing, car loans, etc.)

Let’s go back to that $4,000 monthly income.

28% of $4,000 = $1,120 (your max budget for mortgage + property taxes + insurance)
36% of $4,000 = $1,440 (your total allowed debt payments)

Since you already have $800 in monthly debt, that leaves you $640 for housing. So, your safe mortgage budget is $640/month.

👉 Pro tip: Always use the lower number to be safe.

🏦 Step 4: Estimate the Mortgage Payment

Now let’s figure out what kind of home loan you can afford with that $640/month.

Use a free online mortgage calculator. These tools let you plug in:

Loan amount
Interest rate
Loan term (usually 30 years)
Property taxes
Insurance

Example:

Loan Amount: $120,000
Interest Rate: 6.5%
Loan Term: 30 years
Taxes/Insurance: $150/month

Your total monthly payment might come out to around $640/month.

💥 Bingo! That’s within your budget.

🔍 Other Costs to Consider

Your mortgage isn’t the only cost of owning a home. Don’t forget:

Down payment: Usually 3%-20% of the home’s price.
Closing costs: Typically 2%-5% of the purchase price.
Home maintenance: Expect to spend 1%-2% of the home value each year.
HOA fees: Some homes come with homeowner association fees.

💡 Don’t forget to leave room in your budget for these extra costs.

🛑 Avoid This Common Mistake!

Many first-time buyers make this mistake:
They focus on the maximum they qualify for, not what they can comfortably afford.

Just because a bank approves you for a $300,000 loan doesn’t mean you should borrow that much. Stick to what fits YOUR lifestyle. You want to enjoy your home—not stress about payments.
