See your full conventional payment with PMI included, when PMI ends, and where your DTI lands against Fannie Mae and Freddie Mac guidelines, using the same math a lender runs.

PMI protects the lender on conventional loans with less than 20% down, and it is the trade that lets you buy now with 3% or 5% down instead of saving for a decade. It typically runs about 0.2% to 1.9% of the loan per year based on your credit score and LTV. There is no upfront premium like FHA's 1.75%, and lenders shop several private insurers for your price.
The classic conventional guideline is 28% of gross income for the house payment and 36% with all debts included. Only one of those has teeth: Fannie Mae and Freddie Mac set no hard front-end cap, and with an Approve/Eligible from automated underwriting, total DTIs up to 50% get approved every day. Treat 28/36 as the comfort zone, not the cutoff.
PMI cancels automatically when your balance is scheduled to reach 78% of the original value, and you can request cancellation at 80%. Appreciation can get you there years early: after 2 years of payments, your servicer can cancel based on a new value review once your equity clears 20%. That cancelability is conventional's biggest edge over FHA, where most buyers carry mortgage insurance until they refinance out of it.
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.
