See how much to put down on a home — the dollar down payment, your loan amount, and whether you'll likely pay PMI.
PMI rules vary by loan type — many conventional loans require it under 20% down; FHA and other programs differ. General information, not a lending decision.
Putting 20% down on a conventional loan usually lets you avoid private mortgage insurance (PMI), which can add hundreds a month. But a smaller down payment gets you into a home sooner and keeps cash in reserve — it's a real trade-off, not a rule.
Down payment = price × percent · Loan = price − down payment
Private mortgage insurance protects the lender when you put down less than 20% on a conventional loan. It's an extra monthly cost that typically drops off once you reach 20% equity.
No. Many loans allow 3–5% down (and some none), but a smaller down payment usually means PMI and a larger loan. This tool shows both so you can weigh them.
