How much should you put down?

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

Quick FAQ

What is PMI?

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.

Is 20% down required?

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.
