If you make $120K a year and wonder what mortgage you can afford, here is the straight answer: lenders will approve you for a mortgage loan of roughly $372,000-$443,000 at current rates, which buys a home in the $410,000-$465,000 range depending on your down payment. Below is the exact math so you can adjust it for your situation. Phrased as what mortgage can i afford on 120k salary, the answer is the same range: about a $372,000 loan once taxes and insurance are counted inside the budget, up to $443,000 on principal and interest alone.
Start with your monthly income
$120,000 ÷ 12 = $10,000/month gross. Lenders judge you on two ratios, together called the 28/36 rule:
- Front-end (28%): housing costs ≤ 28% of gross monthly income → $10,000 × 0.28 = $2,800/month
- Back-end (36%): all monthly debts ≤ 36% of gross monthly income → $10,000 × 0.36 = $3,600/month
That $2,800 is your total housing budget: principal, interest, property taxes, homeowners insurance, PMI and HOA - everything.
Converting $2,800/month into a mortgage amount
At 6.5% on a 30-year fixed loan, every $1,000 borrowed costs about $6.32/month in principal and interest. The math:
- P&I only: $2,800 ÷ $6.32 × $1,000 ≈ $443,000 mortgage
- Reality check: that $2,800 must also cover taxes and insurance (~$450/month on a typical home). Real P&I budget: $2,350 → ≈ $372,000 mortgage
So your realistic mortgage range is $372K-$443K. The lower number is what you will actually be approved for once taxes and insurance are counted; the higher number is the theoretical max if taxes and insurance were zero.
What home price does that buy?
| Down payment | Mortgage ≈ $372K buys | Mortgage ≈ $443K buys |
|---|---|---|
| 3.5% (FHA) | ~$385,000 | ~$459,000 |
| 10% down | ~$413,000 | ~$492,000 |
| 20% down | ~$465,000 | ~$554,000 |
Most buyers on $120K land around $410K-$465K with 10-20% down. Our full price breakdown for the rung below: what mortgage can I afford on a $110K salary.
Can you afford a $450,000 house on a $120K salary?
Yes, with a solid down payment. A $450,000 home at 6.5% on a 30-year loan fits the $2,800 monthly housing budget at 20% down, and misses it at lower down payments:
| Down payment | Loan | Principal + interest | Taxes + insurance | PMI (estimate) | Total a month | vs budget |
|---|---|---|---|---|---|---|
| FHA 3.5% ($15,750) | $434,250 | $2,744.76 | $450 | $180.94 | $3,375.70 | $575.70 over |
| 10% ($45,000) | $405,000 | $2,559.88 | $450 | $168.75 | $3,178.63 | $378.63 over |
| 20% ($90,000) | $360,000 | $2,275.44 | $450 | $0 | $2,725.44 | $74.56 under |
With 20% down, the $450,000 home fits with $74.56 a month to spare. With 10% down it runs $378.63 over the guideline, mostly because of PMI. If you are short on down payment, read what is PMI and how to avoid it before you decide. To afford a $500,000 home comfortably at 6.5% with 20% down, you would need roughly a $128,000 salary: a $400,000 loan costs $2,528.27 in principal and interest plus $450 in taxes and insurance, or $2,978.27 a month, which needs $10,637.60 a month gross at the 28% rule.
If you have other debts
This is where most people get tripped up. The back-end rule caps everything at $3,600/month:
- No debts: full $2,800 housing budget → ~$372K-$443K mortgage
- $800/month (car + student loans): housing capped at $2,800 → front-end $2,800 still binds → same range
- $1,500/month in debts: housing capped at $2,100 → mortgage drops to roughly $261,000
- $2,000/month in debts: housing capped at $1,600 → mortgage roughly $182,000
Every $500/month in debt payments erases about $60,000 of mortgage once the back-end rule binds. Paying off a car before house-hunting is one of the highest-leverage moves you can make.
To answer what mortgage can i afford on 120k salary with debts precisely, here are three debt levels after taxes and insurance are counted (6.5%, 30-year):
| Monthly debts | Housing cap (36% minus debts) | Realistic mortgage |
|---|---|---|
| $1,000 (car payment) | $2,600 | ~$372,000 |
| $1,500 (car + student loans) | $2,100 | ~$261,000 |
| $2,000 (car + loans + cards) | $1,600 | ~$182,000 |
At $2,000 a month in debts your borrowing power is roughly half what it is with no debts. Check your own ratio with our debt-to-income calculator before you start house-hunting.
What about a 15-year mortgage?
On $120K, a 15-year loan is tight but not impossible. At 6.0%, $372,000 over 15 years costs $3,139.15/month in P&I alone - already over your $2,800 housing budget before taxes and insurance. A smaller 15-year loan of about $330,000 fits ($2,784.31 P&I at 6.0%), but most buyers are better off with the 30-year term and extra principal payments when they can.
Paid biweekly? Your per-paycheck housing budget
If you are paid every two weeks, your $120K salary breaks down differently, and it helps to think in paychecks instead of months:
- Gross per paycheck: $120,000 ÷ 26 = $4,615.38
- Housing budget per paycheck: $2,800 × 12 ÷ 26 = $1,292.31
- P&I per paycheck on a $372,000 loan at 6.5%: about $1,085.21 (the rest of the $1,292.31 covers taxes and insurance)
Twice a year you get a third paycheck in the same month. If you route those two extra paychecks' housing share toward principal, you pay the loan off years early without feeling a monthly pinch - the biweekly-payment trick, without a special program.
What $200 extra a month does to a $372,000 loan
The realistic $372,000 loan at 6.5% costs $2,351.29 a month in principal and interest and $474,465 in total interest over 30 years. Adding just $200 a month changes that sharply:
- Payoff time: 289 months instead of 360, about 5.9 years early
- Interest saved: about $109,141
- New total interest: about $365,324
That $200 is less than the PMI on a low-down-payment loan, and it buys you almost six years of freedom. Even $100 extra a month saves about $62,051 and cuts the term to 320 months. Run your own version with our mortgage calculator.
Rate changes move the number a lot
The same $2,800/month buys very different mortgages at different rates (30-year, P&I only):
| Rate | Max mortgage on $2,800/mo |
|---|---|
| 5.5% | ~$493,000 |
| 6.5% | ~$443,000 |
| 7.5% | ~$400,000 |
A one-point rate drop is worth roughly $43,000-$50,000 in borrowing power. If rates fall after you buy, refinancing can recover that - check with our refinance calculator whether it pays off.
