Monthly paymentPrincipal, interest, taxes, insurance, mortgage insurance and HOA — drawn as five separate threads, not folded into one number.Open AmortisationThe full schedule, switchable month-wise and year-wise, with a running total and the crossover month called out.Open AffordabilityIncome, debts and cash in, a defensible price out — and a plain statement of which of the three constraints is the one actually holding the number down.Open RefinanceCosts divided by monthly saving is the answer most sites give, and it ignores the fact that a new 30-year term restarts the clock. Both numbers are shown here.Open Extra paymentA recurring extra, a one-off lump sum, or both — against the interest they remove and the months they take off the end.Open Rent vs buyBoth households start with the same cash. Whichever is cheaper in a given month invests the difference; whichever is dearer draws it down. That symmetry is the whole argument.Open FHA MIPThe upfront premium, the annual premium, and the part almost every calculator gets wrong: whether it ever comes off.Open VA purchaseThe VA funding fee changes with the down payment and with whether it is your first use of the entitlement. Exempt borrowers pay none of it.Open VA refinanceAn IRRRL carries a 0.50% funding fee; a VA cash-out carries 2.15% or 3.30%. Both are shown against a true break-even.Open PointsOne point is one percent of the loan, paid today, for a lower rate for as long as you keep it. The only question that matters is how long that is.Open HELOCInterest-only while you draw, then a fully amortising payment that can be several times larger. Both are shown, because the second one is the surprise.Open DSCRDebt-service coverage divides the rent the property brings in by what the property costs to carry. Most lenders want 1.20 or better.Open Fix & flipAcquisition, rehab, points, interest, holding costs and selling costs against the after-repair value — with the cash you actually have to put in.Open
About these numbers
Every default rate on this site is a round illustrative figure chosen because it divides cleanly, not because it is available anywhere. Nothing here is a quote, a pre-qualification, or an offer of credit, and no licence identifier appears on this site because a fictional company has none to publish.
The rules the calculators apply are public: the Homeowners Protection Act for conventional mortgage insurance, HUD Mortgagee Letters 2023-05 and 13-04 for FHA, 38 U.S.C. §3729 for the VA funding fee, and the USDA guaranteed-loan fee schedule. Each page names the one it is using.
