How does it compare with incomes?
For this payment to be 28% of your income, you'd need to earn about $70,019 a year. With your other debts, to stay under 36%: about $54,460 a year.
You need at least $6,993 for the down payment, plus closing costs.
This is an estimate to give you an idea, not a loan offer. Your real payment depends on your rate, your credit, and the insurance and taxes on the home you buy.
Total monthly payment $1,634; principal and interest $1,329.

Cash to close = down payment plus 3% of the price in closing costs (example). FHA also accepts citizens of the Freely Associated States. ITIN loans are not a federal program: each lender sets its own rules, rate and down payment.

How is it calculated?
The same formulas lenders use, with the rules each program publishes. Nothing is hidden.
The formula
Payment = principal and interest + tax ÷ 12 + insurance ÷ 12 + mortgage insurance + HOA. Principal and interest = loan × r ÷ (1 − (1 + r)^−n), with r = yearly rate ÷ 12 and n = months in the term.
Example with the numbers for Oklahoma
Picture a family with the typical income in Oklahoma, $65,039 a year, buying a home at the typical price there, $199,800, with FHA and 3.5% down.

Their payment would be $1,634 a month: 30% of their income, in the “Tight” tier. With your own numbers, the result changes.
Computed from the page's data when it was built; in the tool you replace every number with your own.
What moves the result?
Six things that change the number more than anything else.
-
The price
Every dollar of price is a dollar more of loan. It is the first thing that moves the payment.
-
The down payment
More down, less loan and less mortgage insurance. The minimum depends on the program.
-
The rate
One point of rate changes the payment for the whole term. Compare at least three offers.
-
The term
Over 15 years you pay more per month and far less interest in total than over 30.
-
Tax and insurance
They sit inside the payment. The tax depends on the county; the insurance, on the home and the area.
-
Mortgage insurance
FHA always charges it; conventional loans only with less than 20% down.

Frequently asked questions
What does the monthly payment include?
Principal and interest on the loan, the property tax divided by twelve, home insurance, mortgage insurance when it applies and HOA dues if any. Lenders call it PITI plus mortgage insurance.
Why can my rate differ from 7.18%?
It is the Freddie Mac national average as of November 5, 2026 for a 30-year conventional loan. Your rate depends on your credit, your down payment, the loan type and the lender; compare at least three offers and type yours into the calculator.
What is the minimum down payment?
With FHA, 3.5% of the price if your credit qualifies; with a conventional loan, from 3%; with VA and USDA it can be zero if you meet the requirements. ITIN loans usually ask for more; the example uses 15%.
What if the loan is above the FHA limit?
FHA does not insure loans above your county’s limit (nationally from $541,287 to $1,299,500 for a one-unit home). You would need a bigger down payment or another loan type. Open your county’s calculator to see its limit.
Methodology and sources (Freddie Mac, the Census Bureau, HUD, and FHFA)
- Loan = price − down payment. If you finance the FHA upfront premium (1.75% of the loan) or the VA funding fee (2.15% on first use with no down payment) or the USDA fee (1%), it is added to the loan.
- Principal and interest: the standard amortization formula, with the annual rate divided by twelve and the term in months. At a zero rate, the payment is the loan divided by the months.
- Property tax: the place’s typical effective rate (typical tax ÷ typical value, per the Census) times the price. Home insurance: 0.5% of the value per year, an example you should replace with a real quote.
- Mortgage insurance: FHA per HUD’s tables (annual premium by loan-to-value, term and amount). Conventional: an example PMI of 0.6% a year when the down payment is under 20%, which ends automatically once the balance falls to 78% of the original value. VA has no monthly insurance; USDA charges 0.35% a year.
- Income needed: the payment divided by 28% (housing only) and by 36% counting your other debts. These are common lender references, not program rules.
