What a $300,000 loan actually costs you each month

A $300,000 mortgage payment depends on three things: the interest rate, the loan term (usually 15 or 30 years), and whether you put money down first. On a 30-year loan at 7% interest with no down payment, you pay roughly $1,995 per month in principal and interest alone. At 6%, that drops to about $1,799. At 5%, it's around $1,610. These numbers do not include property taxes, homeowners insurance, or mortgage insurance—which can add $400 to $800 more per month depending on where you live and how much you put down.

The real monthly cost is usually 25% to 35% higher than the principal-and-interest number alone. If you see a $1,995 payment quoted, budget for $2,500 to $2,700 when you add taxes, insurance, and fees. Lenders typically want your total housing payment to be no more than 28% of your gross monthly income, which means you need to earn roughly $9,000 to $10,000 per month before taxes to carry this loan comfortably.

Key Takeaways

  • A $300,000 loan at current rates costs $1,600 to $2,000 per month in principal and interest, plus $400 to $800 more for taxes, insurance, and mortgage insurance.
  • Lenders expect your housing payment to be no more than 28% of your gross income, which means you typically need to earn $9,000 to $10,000 monthly before taxes.
  • Putting down 20% or more eliminates private mortgage insurance and lowers your monthly payment by $100 to $200.
  • Choosing a 15-year loan instead of 30 years nearly doubles your monthly payment but saves you over $200,000 in interest.
  • Your actual approval amount depends on your credit score, debt-to-income ratio, and employment history, not just income alone.

How much you need to earn to afford this payment

Lenders use a debt-to-income ratio to decide how much they will lend you. The standard rule is that your housing payment should not exceed 28% of your gross monthly income. If your total housing cost (mortgage, taxes, insurance, and mortgage insurance) is $2,500, you need to earn at least $8,929 per month gross, or about $107,000 per year. If you have other debts—car loans, credit cards, student loans—lenders also cap your total monthly debt payments at 43% of gross income, which tightens the calculation further.

This is why income alone does not determine whether you can afford the loan. A person earning $120,000 per year with $50,000 in student loan debt and a car payment may not may have access to, while someone earning $95,000 with no other debts might. Before you look at houses, pull your credit report and add up every monthly debt payment you have. Then calculate whether 28% of your gross income covers the housing payment you are considering.

Putting money down to lower your payment

The more you put down, the smaller your loan and the lower your monthly payment. A 20% down payment ($60,000 on a $300,000 home) reduces your loan to $240,000 and eliminates private mortgage insurance (PMI), which typically costs 0.5% to 1.5% of the loan amount annually. That PMI savings alone is $100 to $300 per month. On a 30-year loan at 6%, a $240,000 mortgage costs about $1,439 per month instead of $1,799—a difference of $360 before taxes and insurance are added.

If you cannot save 20%, putting down 10% ($30,000) still helps. Your loan becomes $270,000, and while you still pay PMI, the payment drops to around $1,619 per month. PMI is not permanent—once your loan balance falls to 80% of the home's original value through regular payments, you can request to have it removed. Some loans remove it automatically at that point; others require you to ask. Check your loan documents or call your lender to confirm the removal policy.

Choosing between a 15-year and 30-year loan

A 15-year loan has a much higher monthly payment but saves enormous amounts in interest. On a $300,000 loan at 6% interest, a 30-year mortgage costs $1,799 per month and totals $647,500 over the life of the loan—meaning you pay $347,500 in interest. A 15-year loan on the same amount costs $3,066 per month but totals only $551,880—saving you about $95,600 in interest. The monthly difference is $1,267, which is why most people choose 30 years.

The 15-year option makes sense if you have stable income, no other major debts, and want to own the home free and clear before retirement. It also builds equity much faster, so you own more of the home sooner. But if you are stretching to afford the payment, a 30-year loan gives you breathing room. You can always pay extra toward principal in months when you have surplus cash, which shortens the loan without locking you into a higher monthly payment.

What happens if you cannot afford the payment right now

If the $300,000 loan payment is out of reach, you have several options. The first is to look at less expensive homes. A $200,000 home with the same terms costs roughly $1,200 per month in principal and interest—a significant drop that may bring you within the lender's 28% threshold. The second is to save for a larger down payment, which reduces the loan amount and your monthly cost. Putting down $50,000 instead of $30,000 lowers the loan to $250,000 and saves you about $200 per month.

The third option is to improve your financial position before applying. Pay down credit card balances and car loans to lower your debt-to-income ratio, which may allow lenders to approve you for a larger loan at the same income level. Raise your credit score by making all payments on time for six months to a year—a score improvement of 50 to 100 points can lower your interest rate by 0.25% to 0.5%, which reduces your monthly payment by $75 to $150. The fourth option is to wait and save. If you can earn more income or reduce other debts, your approval odds and the loan terms you receive will improve.

Understanding interest rates and how they change your payment

Interest rates move daily and vary based on your credit score, down payment size, loan term, and the lender you choose. A person with a 750 credit score might get 5.8% on a 30-year loan, while someone with a 650 score pays 6.8% on the same loan. That one percentage point difference costs about $180 more per month on a $300,000 loan. Shopping with at least three lenders takes a few hours but can save you thousands over the life of the loan.

Rates also change based on whether you lock in a fixed rate or choose an adjustable-rate mortgage (ARM). A fixed rate stays the same for the entire loan term, so your payment never changes. An ARM starts lower but increases after a set period (often 5 or 7 years), which means your payment could jump by $200 to $400 per month later. ARMs are risky if you are already stretching to afford the payment. Stick with a fixed rate unless you plan to sell or refinance before the rate adjusts.

Costs beyond the monthly payment you need to budget for

The monthly payment is only part of homeownership. You also pay closing costs upfront, which typically run 2% to 5% of the loan amount—$6,000 to $15,000 on a $300,000 mortgage. These cover the appraisal, title search, underwriting, and lender fees. Some of these costs can be rolled into the loan, but that increases your monthly payment. Property taxes vary wildly by location; some areas charge 0.5% of home value annually, others charge 2% or more. A $300,000 home in a high-tax area can cost $500 to $1,000 per month in taxes alone.

Homeowners insurance is required by lenders and typically costs $100 to $200 per month, depending on the home's age, location, and your coverage level. Maintenance and repairs average 1% of the home's value per year, which is $3,000 annually or $250 per month—though some years you spend nothing and others you spend much more. If you have an HOA, add that fee too. All of these costs together often total 35% to 45% of your gross income, not just the 28% housing payment ratio. Budget conservatively before you commit to the loan.

Frequently Asked Questions

Can I get approved for a $300,000 loan if I earn $80,000 per year?

Probably not. At $80,000 annual income, 28% of your gross monthly income is about $1,867. A $300,000 loan at current rates costs $2,000 to $2,500 per month including taxes and insurance, which exceeds that threshold. You might may have access to for a $200,000 to $220,000 loan instead, or if you have minimal other debt and a strong credit score, a lender might stretch to $250,000.

What is the difference between pre-qualification and pre-approval?

Pre-qualification is an estimate based on information you provide—it takes minutes and is not binding. Pre-approval involves a credit check and verification of income and assets; it shows sellers you are serious and takes a few days. Pre-approval does not may provide final approval, which comes only after the home is appraised and all documents are verified.

Should I pay off my car loan before applying for a mortgage?

If paying it off takes several months and delays your home purchase, probably not. But if you can pay it off quickly, do it. Removing a $400 monthly car payment improves your debt-to-income ratio significantly and may allow you to may have access to for a larger loan or better rate. The timing depends on how soon you want to buy.

What if my interest rate is locked but rates drop before closing?

Once you lock a rate, it is fixed for a set period—usually 30 to 60 days. If rates drop after you lock, you cannot change your rate unless you pay a fee to unlock and re-lock at the new rate. Some lenders offer a "float down" option that lets you lock in a lower rate if it drops, but this costs extra upfront. Ask your lender about this option before you lock.

Can I use a co-signer to may have access to for a larger loan?

Yes. A co-signer with strong income and credit can help you may have access to for a larger loan or better rate. However, the co-signer is legally responsible for the debt if you default, and the loan appears on their credit report and counts against their own debt-to-income ratio. Make sure any co-signer understands the full obligation.
