Before building Down Payment Calculator, we checked calculator.net's down payment calculator directly.
How much down payment calculator, with a warning but no number
It correctly flags the US mortgage rule: put down less than 20% and lenders will typically require PMI (Private Mortgage Insurance). The exact text: "you will be asked to pay PMI Insurance." What it doesn't do is calculate what that actually costs per month — you get the warning, not the number.
Down payment calculator with pmi estimate, filled in
Put in a home price and down payment under 20%, and this tool estimates the actual monthly PMI cost from a typical rate (adjustable, since real rates vary by lender and credit profile) — shown right alongside your principal & interest payment, not just a footnote warning.
Closing costs and down payment calculator, all cash-needed numbers in one place
Down payment amount, loan amount, closing costs, and total cash needed at closing are all broken out — everything you'd actually need to know before you show up with a check.
