Mortgage Calculators & Homebuying Tools
Six free mortgage calculators and a library of plain-English guides, all in one place. Estimate a monthly payment, size a realistic budget, test a refinance or line up loan scenarios side by side, then bring those numbers to Sterling Smith when you want a figure you can actually count on.
Calculators
Run the numbers before you talk to a lender
Each tool answers one specific question. None of them asks for your name, email or a credit pull, and every result updates as you type.
Mortgage Payment Calculator
Turn a price, down payment, rate and term into a monthly figure, then layer in property tax, insurance, HOA dues and PMI for the full housing cost.
Learn more →Affordability Calculator
Work backward from income, monthly debts and cash on hand to a price ceiling based on the common 28%/36% debt-to-income guideline.
Learn more →Refinance Calculator
Compare your existing loan against a new rate and term, factor in closing costs, and see how many months it takes for the savings to pay for themselves.
Learn more →Loan Comparison Tool
Line up as many as three scenarios with different prices, down payments, rates, terms and mortgage insurance to compare payment, lifetime interest and cash to close.
Learn more →Rates & Terms Finder
Answer a short questionnaire about your goals and profile to see which loan programs and term lengths are worth a closer look.
Learn more →Extra Payment Calculator
Test a recurring or one-time principal prepayment and watch the payoff date move up and the interest bill shrink.

What a calculator can't tell you
Every estimate rests on inputs you supply: a guessed rate, a tax figure pulled from a listing, an insurance premium nobody has quoted yet. That makes the output useful for planning, but it is never an approval. Real qualification hinges on details no form field captures:
- Credit profile — your score, the depth of your accounts and any recent inquiries all influence pricing and eligibility.
- Documented income — a salaried W-2 employee is verified very differently from a self-employed borrower using bank statements.
- Property type — condos, multi-unit buildings, manufactured homes and rural properties each carry their own guidelines.
- Program fit — FHA, VA, USDA, conventional and specialized Non-QM programs evaluate the same file in different ways.
A short conversation replaces a lot of guesswork. Starting a prequalification requires no hard credit pull, and our team responds within two business hours.

How to use these tools together
The calculators work best as a sequence rather than in isolation.

Start with the affordability calculator to see what price range your income and debts support.
Price a real home
Plug a specific listing into the payment calculator, including that property's taxes, insurance and HOA dues.

Use the comparison tool and the rates and terms questionnaire to weigh down payment, term and program trade-offs.

Mortgage tools FAQ
Which mortgage calculator should I start with?
If you haven't picked a price range yet, begin with the home affordability calculator. Once you have a specific property in mind, switch to the payment calculator to see the full monthly cost of that home.
Do I have to enter personal information to use the tools?
No. Every calculator runs in your browser with no sign-up, email address or credit check. You only share details if you decide to request a prequalification.
How accurate are online mortgage calculators?
The math is precise, but the output is only as good as the inputs. Rates, taxes, insurance and mortgage insurance all vary by borrower and property, so treat every result as a planning estimate rather than a quote.
Can I get an actual rate quote from this site?
Personalized rate quotes come directly from Sterling Smith after a quick review of your goals and profile. The Rates & Terms Finder helps you narrow down programs first, and you can request a quote whenever you're ready.
Are these tools useful if I already own a home?
Yes. Homeowners often use the refinance calculator to evaluate a new rate or term and the extra payment calculator to plan an earlier payoff. For cash-out or streamline options, see our refinancing solutions.
