20% or more down: no PMI, and you'll usually qualify for a slightly better rate.

Assumptions
  • PMI is estimated as a flat annual percentage of the loan while LTV exceeds 80%; actual premiums vary by credit score and LTV tier.
  • The FHA 3.5% row uses the same PMI rate as an approximation for FHA's MIP.
  • Monthly payment is principal and interest only — taxes, insurance and HOA are excluded.

3.5% is the FHA minimum; FHA charges its own mortgage insurance (MIP) rather than PMI, and it usually lasts the life of the loan.

How this is worked out

The formula

Down payment = price × down %      (or the amount you enter)
Loan = price − down payment
LTV = loan ÷ price
PMI per month ≈ loan × PMI rate ÷ 12   while LTV > 80%
P&I = loan × r(1 + r)^n ÷ ((1 + r)^n − 1)

What this assumes

  • PMI is estimated as a flat annual percentage of the loan while LTV exceeds 80%; actual premiums vary by credit score and LTV tier.
  • The FHA 3.5% row uses the same PMI rate as an approximation for FHA's MIP.
  • Monthly payment is principal and interest only — taxes, insurance and HOA are excluded.

About this calculator

The down payment does three jobs at once: it sets the size of your loan, it sets your loan-to-value ratio (which drives your rate and whether you pay mortgage insurance), and it's the biggest check you'll write at closing. This calculator converts a price and a percentage — or a dollar amount you've saved — into all of those, and lays out the standard 3.5%, 5%, 10%, 15% and 20% options side by side so you can see what each extra chunk of savings actually buys you.

How to use it

Enter the price. Choose whether you're thinking in percent ("I want to put 10% down") or dollars ("I have $45,000"). Open More options to set the rate, term and PMI rate used for the monthly columns — the PMI default of 0.5% a year is mid-range; borrowers with lower credit scores or 5% down pay closer to 1%, strong borrowers at 15% down closer to 0.3%.

Reading the results

  • Loan-to-value is the lender's key risk number. Above 80% you pay private mortgage insurance on a conventional loan; above 95–97% most conventional programs stop.
  • Estimated PMI is a monthly cost that protects the lender, not you. It goes away once you reach 20% equity — automatically at 22% under federal law, or on request at 20%.
  • P&I + PMI in the scenario table is the fair way to compare down payments: less down means both a bigger loan payment and an insurance premium on top.

How much should you put down?

Twenty percent avoids PMI and gets the best pricing, but waiting years to save it while prices and rents rise can cost more than the PMI would. Many first-time buyers put down 5–10% and cancel PMI after a few years of appreciation and paydown. Keep enough cash after closing for an emergency fund and the first year of repairs — a 20% down payment that leaves you with nothing is riskier than 10% with reserves.

Minimums by loan type

  • Conventional: 3% for some first-time programs, otherwise 5%; PMI above 80% LTV.
  • FHA: 3.5% with a 580+ credit score; mortgage insurance premium (MIP) instead of PMI, including an upfront 1.75% fee, and usually for the life of the loan.
  • VA and USDA: 0% for eligible borrowers, with a funding or guarantee fee instead of monthly insurance.

Closing costs — typically 2–5% of the price — come on top of the down payment.

Frequently asked questions

How much is a 20% down payment on a $400,000 house?

$80,000, leaving a $320,000 loan at 80% LTV with no PMI. Closing costs of roughly $8,000–$20,000 come on top.

What is the minimum down payment for a house?

3% on some conventional programs, 3.5% for FHA, and 0% for VA and USDA loans if you're eligible. Anything under 20% on a conventional loan means paying PMI until you reach 20% equity.

How much does PMI cost?

Usually 0.3% to 1.5% of the loan per year, paid monthly, depending on credit score and how far below 20% you are. On a $360,000 loan at 0.5% that's about $150 a month.

When does PMI go away?

You can request cancellation once your balance reaches 80% of the original value, and the lender must cancel it automatically at 78%. Appreciation can get you there sooner if you request a new appraisal.

Is it better to put more down or keep cash?

Put down at least enough to avoid PMI if you can do it while keeping an emergency fund and money for repairs. If reaching 20% would drain you, a smaller down payment with reserves is safer; you can cancel PMI later.
