“You need 20% down to buy a house.” It’s one of the most repeated — and most misunderstood — rules in personal finance. The truth is more flexible and more interesting: you can buy with far less, but how much you put down changes your monthly payment, your interest costs, and whether you pay extra fees. Let’s clear up exactly how much down payment you actually need, and how much you should aim for.
The myth of 20%
You do not need 20% down to buy a home. That number is a guideline, not a requirement. Many loan programs allow much smaller down payments:
| Loan type | Typical minimum down payment |
|---|---|
| Conventional loan | as low as 3% |
| FHA loan | 3.5% |
| VA loan (eligible veterans) | 0% |
| USDA loan (eligible rural areas) | 0% |
So a first-time buyer can often get in with 3–3.5% down. On a $300,000 home, that’s roughly $9,000–$10,500 — a far cry from the $60,000 that “20%” implies.
So why does 20% get all the attention?
Because 20% is the threshold where two good things happen:
1. You avoid PMI. With less than 20% down on a conventional loan, you usually pay private mortgage insurance — an extra monthly cost that protects the lender, not you. Put 20% down and it disappears. (More in What Is PMI and How Do You Avoid It.)
2. You borrow less, so your monthly payment and total interest are lower.
So 20% isn’t required — it’s just the point where your costs drop noticeably.
The trade-off: lower down payment vs. lower monthly cost
A smaller down payment gets you in the door sooner but raises your monthly payment and total interest, and may add PMI. A larger down payment costs more upfront but saves money every month and over the life of the loan. Here’s the tension on a $300,000 home at 6.5% over 30 years (rough figures):
- 3% down ($9,000): bigger loan (~$291,000), higher payment, plus PMI until you build equity.
- 20% down ($60,000): smaller loan ($240,000), lower payment, no PMI.

How much should you put down?
There’s no single right answer, but a few sensible principles: don’t drain your emergency fund (keep your emergency fund intact); more down means lower cost, so put down as much as you comfortably can without leaving yourself cash-poor; and if 20% would take years to save, a smaller down payment now (accepting PMI temporarily) can beat waiting — especially since PMI can be removed later once you build 20% equity. The right number balances getting in the door against keeping a safety cushion.
Don’t forget closing costs
Your down payment isn’t the only cash you need at the table. Closing costs typically run 2–5% of the loan and cover lender fees, title, appraisal, and more. Budget for these on top of your down payment so they don’t catch you short. The U.S. Consumer Financial Protection Bureau breaks down the full cash-to-close picture at consumerfinance.gov.
How to save your down payment
Treat it like any big savings goal: set the target, set a deadline, and automate it. The Savings Goal Calculator turns “I need $30,000 in 3 years” into a monthly number you can actually budget for, and keeping it in a high-yield savings account earns a little while you build.
Frequently asked questions
Do I really need 20% down?
No. Many loans allow 3–3.5% down (some 0%). But under 20% you usually pay PMI on a conventional loan, raising your monthly cost until you reach 20% equity.
Is a bigger down payment always better?
It lowers your payment and total interest, but not if it empties your emergency fund. Put down as much as you comfortably can while keeping a cash cushion.
What’s the minimum down payment for a first-time buyer?
Often 3% (conventional) or 3.5% (FHA). Eligible veterans and some rural buyers may qualify for 0% down.
Can I get rid of PMI later?
Yes — on conventional loans, PMI can typically be removed once you reach about 20% equity.
The takeaway
You don’t need 20% down — many buyers get in with 3–3.5% — but 20% is the level where you avoid PMI and lower your costs. Put down as much as you comfortably can without draining your emergency fund, budget separately for closing costs, and model different down payments in the Mortgage Calculator.
