How this calculator works
Your down payment is simply the home price multiplied by the percentage you choose. The loan amount is what’s left over — the price minus your down payment.
Private mortgage insurance (PMI) is generally required when your down payment is below 20% of the price, so any row under 20% in the table is flagged. A larger down payment lowers your loan, your monthly payment, and removes PMI once you reach the 20% mark.
Frequently asked questions
How much down payment do I really need?
Many conventional loans allow as little as 3%, and some government-backed loans require 0–3.5%. A 20% down payment avoids PMI and lowers your monthly payment, but it isn’t required to buy.
What is PMI and how do I avoid it?
PMI is private mortgage insurance that protects the lender when your down payment is under 20%. Avoid it by putting down 20% or more; on most loans it falls off automatically once you reach 20% equity.
Can I get help with my down payment?
Yes. Many state and local programs offer down payment assistance for first-time and lower-income buyers. See our down payment assistance guide for details.
