Utah Home Affordability Calculator

Quick answer

A Utah home affordability calculator works backward from your income. It takes your gross annual income, subtracts your monthly debt payments, applies the 28/36 lender guideline, then backs out Utah property taxes, homeowners insurance, and PMI to arrive at a purchase price. With Salt Lake County’s median sale price sitting near $600,000, a buyer needs roughly $150,000 to $170,000 of household income to carry that comfortably at current rates with a conventional down payment. Cache, Box Elder, and Tooele counties remain considerably more attainable.

How to use this calculator

Enter your annual household income before taxes, your total monthly debt payments, and the down payment you have saved. Adjust the interest rate to whatever your lender is actually quoting, and set the property tax rate for your county if you know it. The result shows an estimated home price, the monthly payment behind it, and the breakdown of principal, interest, taxes, insurance, and PMI.

Change one input at a time. Watching the price move when you pay off a car loan, or when you add $10,000 to your down payment, is more useful than the headline number itself.

What the 28/36 rule actually says

The 28/36 rule is the conservative version of what underwriters look at.

• Front-end ratio (28 percent). Your full housing payment, meaning principal, interest, property taxes, homeowners insurance, mortgage insurance, and HOA dues, should stay at or under 28 percent of gross monthly income.
• Back-end ratio (36 percent). Every recurring debt payment combined, housing plus everything else, should stay at or under 36 percent of gross monthly income.

The calculator uses whichever of the two limits is lower for your situation, which is why heavy car payments or student loans can cut your price range even when your income is strong.

Approved is not the same as comfortable

This is the part most calculators skip, so here it is plainly. Many lenders will approve a well qualified borrower at 43 to 50 percent back-end DTI, sometimes higher with compensating factors. That is a real approval and the loan will fund. It is also a payment that leaves very little room.

Underwriting cannot see your childcare costs, your retirement contributions, the trip you take every year, or the fact that a first house tends to generate a few thousand dollars of unplanned spending in its first twelve months. Nobody has ever called me a year after closing to say their payment was too small.

The honest way to use this tool: decide the monthly payment you want to live with, then work back to the price. If that lands under the maximum a lender would hand you, good. That gap is your margin.

What lenders count as debt

Counted: car loans and leases, student loans (including a calculated payment on deferred or income driven balances), minimum credit card payments, personal loans, co-signed loans, and court ordered child support or alimony.

Generally not counted: utilities, groceries, phone and internet, health insurance premiums, 401k contributions, streaming subscriptions, and in most cases childcare. Those do not appear in your DTI, but they absolutely appear in your checking account, which is another reason the approved figure runs ahead of the comfortable one.

Paying off a small balance with a large minimum payment, such as a $450 car note with nine payments left, can raise your price range more than the same dollars added to your down payment. Ask your lender to run both scenarios before you decide.

How the down payment changes the math

More money down lowers the loan, which lowers the payment, which raises the price you can reach on the same budget. It also affects mortgage insurance:

• Under 20 percent down on a conventional loan, expect PMI of roughly 0.3 to 1.0 percent of the loan amount per year, driven by credit score and down payment size. It drops off automatically as you approach 20 to 22 percent equity.
• At 20 percent or more, PMI goes away and that entire amount moves back into principal and interest, so your workable price range rises.
• FHA loans carry their own mortgage insurance with different removal rules. VA loans have no monthly mortgage insurance, which is a meaningful advantage for eligible Utah buyers.

Do not empty every account to reach 20 percent. You still need cash for closing costs, and you want reserves after you move. Our Utah closing cost calculator and the Utah closing costs guide cover what that side of the ledger looks like.

Utah specifics worth knowing

• Property tax. Utah taxes a primary residence on only 55 percent of market value thanks to the 45 percent residential exemption, so effective rates land near 0.55 percent of value statewide, roughly half the national average. Rates vary by county and by taxing district, so check yours with the Utah property tax calculator or the full rates for all 29 counties.
• Homeowners insurance. Budget around $1,300 a year for a typical Wasatch Front single family home. Older homes, larger homes, and homes in wildland interface areas run higher.
• HOA dues. Not included in the calculator. Condos, townhomes, and master planned communities commonly add $50 to $400 a month, and that comes straight out of your 28 percent housing budget.
• Second homes and short term rentals do not get the residential exemption, so property taxes on the same house run roughly 80 percent higher. That changes affordability on a Park City or St. George purchase considerably.
• Prices vary a lot by county. Salt Lake and Utah counties sit well above the state median, while Cache, Box Elder, and Tooele counties stretch the same income further. Where you look matters as much as how much you make.

This is an estimate, not a pre-approval

Every figure here is a planning estimate. It is not a loan approval, not a rate quote, and not an appraisal. Actual approval depends on credit score, employment history, asset reserves, loan program, and the lender’s own overlays, none of which a calculator can see.

What to do next

1. Set your target payment, not just your maximum price. Use the payment breakdown above rather than the headline figure.
2. Get pre-qualified, then pre-approved. A lender verifies income and credit and issues a written letter you can attach to an offer. In competitive Utah price bands, an offer without one usually does not get read. Start with our loans and finance overview, and see who we trust on our Utah mortgage lenders page.
3. Run a full payment scenario. The Utah mortgage calculator folds taxes, insurance, and PMI into one monthly number so you can sanity check the result.
4. Talk it through. Call 801-999-8005 or get in touch, and we will connect you with a Utah lender who fits your situation and map out what your number actually buys in the areas you are considering. Ready to start looking? Head to buying a home in Utah.
