How Much Down Payment Do You Need for a House?

One of the biggest hurdles in buying a home is saving for a down payment. Whether you're a first-time buyer or moving up to a larger home, understanding how much you needβ€”and how long it will take to save itβ€”can make the difference between feeling overwhelmed and having a clear plan.

The Standard Down Payment Percentages

Most lenders and loan programs define down payment requirements in percentage terms. Here's what each common threshold means in practice:

  • 3% downβ€” The minimum for most conventional loans (Fannie Mae's HomeReady and Freddie Mac's Home Possible programs). You'll pay PMI until you reach 20% equity, but it gets you into a home faster.
  • 3.5% down β€” The FHA loan minimum for borrowers with a credit score of 580+. FHA loans have more lenient qualification requirements but include both upfront and annual mortgage insurance premiums.
  • 5–10% down β€” A practical middle ground that reduces your loan size and monthly payment while still requiring PMI. Many buyers in competitive markets aim for this range.
  • 20% downβ€” The magic number that eliminates Private Mortgage Insurance (PMI) on conventional loans. On a $400,000 home, that's $80,000β€”a significant savings goal, but one that eliminates a monthly insurance cost of $200–$400.

What Is PMI and How Much Does It Cost?

Private Mortgage Insurance protects the lender (not you) if you default on the loan. Lenders require it when your down payment is less than 20% on a conventional mortgage. PMI typically costs between 0.5% and 1.5% of the original loan amount per year, paid as a monthly premium.

On a $380,000 loan (5% down on a $400,000 home), you might pay $158–$475 per month in PMI. The good news: once your equity reaches 20% through payments and/or appreciation, you can request PMI cancellation. Under the Homeowners Protection Act, lenders must automatically cancel PMI once you reach 22% equity based on your original payment schedule.

How to Save for a Down Payment Faster

The fastest path to a down payment combines income growth, expense reduction, and smart saving strategies:

  • Open a dedicated high-yield savings account (HYSA)β€” Earn 4–5% APY on your savings instead of 0.01% at a traditional bank. On $30,000 saved, that's $1,200–$1,500 per year in interest.
  • Automate your monthly contribution β€” Set up an automatic transfer on payday before you can spend the money. Even $500/month adds up to $6,000/year plus interest.
  • Redirect windfalls β€” Tax refunds, bonuses, and side income can dramatically shorten your timeline. A single $5,000 tax refund could cut 5–6 months off your savings goal.
  • Explore down payment assistance programs β€” Many states and municipalities offer grants or low-interest second mortgages to first-time buyers. Some programs cover 3–5% of the purchase price outright.
  • Check gift fund rules β€” FHA and conventional loans allow down payment funds to be gifted by family members, with proper documentation.

Don't Forget Closing Costs

Your down payment is only part of the upfront cash you'll need. Closing costs typically run 2–5% of the loan amount and cover items like origination fees, appraisal, title insurance, and prepaid taxes and insurance. On a $400,000 purchase with 10% down, expect to need an additional $7,200–$18,000 at closing. Budget for these alongside your down payment savings.

Should You Put More or Less Down?

The answer depends on your overall financial picture. Putting down more means a lower monthly payment, less interest paid over the life of the loan, and no PMIβ€”but it also ties up cash that could be invested elsewhere. If your mortgage rate is 7% and you can earn 8–10% in the stock market, there's a mathematical argument for a smaller down payment. However, the psychological peace of mind from a lower payment and no PMI has real value too.

Most financial planners suggest keeping 3–6 months of expenses in an emergency fund even after closing, so don't deplete all your savings for a larger down payment.
