How the estimate works & official sources
Principal and interest use standard fixed-rate amortization, including a zero-interest case. The monthly total adds the costs you enter, whether paid through escrow or separately. Annual taxes and insurance are divided by twelve. Conventional PMI is your editable assumption and is not inferred from a credit score. At or below 80% LTV, this model assumes no borrower-paid monthly PMI.
FHA uses the published annual-MIP tiers and a first-year average scheduled balance with HUD rounding. VA fee assumptions depend on down payment, first/subsequent use and explicitly selected exemption status. USDA uses the fiscal-year-2026 fees and a first-year scheduled-balance estimate. These are planning calculations, not servicing schedules or eligibility checks.
Cash still needed = down payment + assumed closing costs/prepaids + program fees paid in cash − applicable entered credits − earnest money already paid, with a floor of zero. A zero result does not imply that a refund or zero-cash loan is available. General closing costs are a user-entered budget, not a title-rate or fee quote. This worksheet does not calculate temporary buydowns, predict rate pricing from points or credit scores, determine tax exemptions, or calculate APR.
