Down Payment Calculator
🇺🇸 US-specific: PMI (Private Mortgage Insurance) is required below 20% down under conventional US mortgage rules — this threshold doesn't apply in every country's mortgage system.
Enter a positive home price and a down payment percentage from 0 to 100.
Free down payment calculator that estimates your actual monthly PMI cost when your down payment is under 20% — we checked calculator.net's down payment calculator directly and it only warns that PMI will likely apply, without calculating what it actually costs.
How it works
- Enter the home price, down payment percentage, closing costs, and loan terms
- See your down payment amount, loan amount, closing costs, and total cash needed at closing
- If your down payment is under 20%, see an estimated monthly PMI cost alongside your principal & interest payment
Frequently asked questions
Why does this show an estimated PMI cost?
We checked calculator.net's down payment calculator directly — it warns you that PMI will likely be required under 20% down, but never estimates the actual dollar amount. This tool calculates it from a typical PMI rate (which you can adjust) so you see the real monthly cost, not just a warning.
Is the PMI estimate exact?
No — actual PMI rates depend on your credit score, loan type, and lender, typically ranging from about 0.5% to 1.5% of the loan annually. Adjust the rate field to match a real quote once you have one.
