These are national daily averages from Optimal Blue, not a quote. Your actual rate depends on your credit, down payment, loan type and any points you pay. The date is shown at the bottom of the panel. Nothing here changes the rate you typed into the calculator.

Loan Amount iPurchase price minus your down payment. Conventional loans have no upfront mortgage insurance fee to roll in, so unlike FHA, what you borrow is exactly what you owe on day 1.
$380,000
Loan-to-Value iYour loan divided by the home's price. LTV decides whether you pay PMI at all (above 80%) and how much. Along with your credit score, it is the biggest lever on your PMI rate: crossing under 95%, 90%, or 85% each steps the rate down.

Monthly PMI iPrivate mortgage insurance, required under 20% down. Estimated from typical borrower-paid monthly PMI pricing for your credit band and LTV. Your exact quote depends on the insurer and your full file, and lenders shop several insurers, so treat this as a realistic middle.

PMI Ends iPMI is temporary by law. It cancels automatically when your balance is scheduled to reach 78% of the original value, and you can request cancellation at 80%. This readout shows the automatic date on your amortization schedule. With appreciation and 2 years of payments, many owners cancel years sooner through a value review with their servicer.

Income iAdd every income source you receive. All of it counts toward your DTI. Employment income, military base pay, retirement, second jobs, and self-employment are taxable and drive the estimated income taxes. BAH, BAS, VA disability, Social Security, and child support are non-taxable. Conventional guidelines let a lender gross up non-taxable income by 25% in the DTI calculation, and this calculator applies the same boost. Rental income is counted at 75%, the same haircut a lender applies.
Total Monthly Income

Est. Income Taxes iEstimated the way a lender runs a quick paycheck check: 2026 federal brackets and standard deduction, Social Security and Medicare, plus an approximate state income tax for your state, calculated on a monthly basis with zero adjustments. Non-taxable income is excluded. Local taxes are not included.

Conventional loans qualify you on gross income, so taxes never change your DTI. They are here so you can see what is actually left over each month.

2Front-end (housing) ratio iYour full house payment, including PMI, divided by your gross monthly income. The classic conventional rule of thumb is 28%, but Fannie Mae and Freddie Mac set no hard cap on it. Automated underwriting looks at the total DTI in step 3, so treat 28% as a comfort marker, not a wall.

3Back-end (total DTI) ratio iYour house payment plus all monthly debts, divided by your gross monthly income. 36% is the classic conventional guideline, and with an Approve/Eligible from automated underwriting, conventional loans close up to 50% DTI. Non-taxable income is grossed up 25% in this math, the same boost conventional guidelines allow a lender.

    Where your income goes iYour gross monthly income, split the way your budget actually feels it. What's left after estimated income taxes, the full house payment including PMI, and your monthly debts is the money your family lives on. Underwriting doesn't check this number, but you should.

    What is PMI?

    PMI is insurance that protects the lender when you put less than 20% down. It's the trade that lets you buy with 3% or 5% down instead of saving for years. Your credit score and down payment set the price, and there's no upfront fee like FHA has.

    PMI doesn't last forever

    It drops off on its own when your balance reaches 78% of the original value, and you can ask to have it removed at 80%. If your home goes up in value, you may be able to drop it a few years sooner.

    The 28/36 rule, and how far it bends

    The old rule says 28% of your income for the house and 36% once you add your debts. Only the second number really matters. With an automated approval, conventional loans close with total DTI up to 50%.

    Passing here isn't an approval

    A lender looks at your whole file: income, assets, debts, credit, and payment history. Your credit score sets both your rate and your PMI, so keep it clean while you shop.

    A preapproval turns this estimate into an exact rate, an exact PMI quote, and a budget you can shop with. It costs nothing, and it does not lock you into anything.

    This calculator is an educational estimate, not a loan approval, a preapproval, or financial advice. It models typical borrower-paid PMI pricing and conventional DTI guidelines, but PMI quotes vary by insurer and full credit profile, a lender verifies your complete file: income, assets, liabilities, credit, and payment history, and may apply its own overlays. Taxes and insurance figures are estimates that vary by property and location, and conforming loan limits vary by county. Confirm your numbers with a licensed loan officer before making decisions.
