How the Home Affordability Calculator works

Estimate what home price fits your income, debts, and expenses.

Show the math

Formula

Max home price ≈ (target monthly PITI × qualifying factor) at the front-end DTI limit for the loan program. Ondo applies conservative property tax and insurance defaults; adjust for your county.

Inputs

Gross monthly income (USD)
Monthly debts (USD)
Down payment (USD)
Annual interest rate (%)
Loan term (years)
Loan program (conventional, FHA, VA, USDA)

Notes

Front-end and back-end DTI thresholds vary by program; consult a loan officer for a binding qualification.
Monthly debts means counted obligations on the credit report (and other debts the investor requires), not a DIY list. HOA is usually housing, not this box.
Variable income is typically averaged. Do not enter last month’s best deposit as if it were base pay.

Rates, terms, and payments are illustrative estimates, not a quote or a commitment to lend. Not a substitute for underwriting. Equal Housing Lender. See our licensing and disclosures page.

What these affordability inputs actually count

This tool illustrates a price range from income, debts, and housing expenses. It is not underwriting. Snapshot as of 2026-08.

Gross monthly income: When income is overtime, bonus, commission, or 1099, underwriters typically average a documented history (often 12–24 months) rather than using the highest recent month. Enter an average you can document, not last month’s best deposit.
Monthly debts: Back-end DTI is all counted monthly debts divided by gross monthly income. Count minimums that show on the credit report (installments, revolving, student loans as the investor requires). Do not omit a car payment you plan to “pay off later.” HOA is usually housing, not this box.
Down payment: Cash toward price, not closing costs. Gift funds and DPA can fund this only when the program allows and the paper trail is complete.
Rate: An illustration rate you type in. It is not today’s quote, a lock, or APR. APR also includes most lender fees.
Taxes, insurance, HOA: Front-end DTI includes PITI plus HOA when it applies. Front-end DTI is housing payment (PITI plus HOA if applicable) divided by gross monthly income. County tax and HOA vary widely in Utah; the default is not your bill.

Terms used in this calculator

Not sure what one of these means? Each links to a full definition.

DTI (Debt-to-Income Ratio): The share of your gross monthly income taken up by monthly debt payments, including the proposed housing payment.
Down payment: The share of the purchase price you pay in cash, becoming your starting equity in the property.
PMI (Private Mortgage Insurance): Insurance on a conventional loan that protects the lender when the borrower has less than the program’s required equity.
PITI: Principal, Interest, Taxes and Insurance, the four parts of a typical monthly mortgage payment.
Pre-qualification: An early estimate of what you might borrow, based on information you provide rather than verified documentation.
HOA (Homeowners Association): An association governing a community, collecting dues and enforcing rules that can include rental restrictions.

DTI: Front-End vs Back-End with HOA

HOA dues are housing expense in front-end DTI, then roll into back-end with other debts. A modest PITI plus a large HOA can still fail the ratio.
