How Much Down Payment Do You Need?
You don't need 20% down to buy a house. That number is a myth left over from older lending rules. In practice, many conventional loans accept as little as 3% down and FHA loans as little as 3.5%. Putting 20% down has real benefits — it avoids mortgage insurance and shrinks your payment — but it isn't a requirement. The right down payment is the one that gets you into a home you can comfortably afford without draining your safety net.
Where the "20%" myth comes from
For a long time, 20% was the unofficial gold standard because it's the threshold where lenders stop charging private mortgage insurance (PMI) on conventional loans. So "20% down" became shorthand for "enough down to avoid extra fees." But that's not the same as a minimum to qualify.
Today, lenders offer a range of low-down-payment programs precisely because waiting to save 20% can take years — and in many markets, home prices rise faster than most people can save. The real question isn't "Do I have 20%?" It's "What down payment lets me buy responsibly, and what does each option cost me month to month?"
It helps to separate two ideas that often get tangled. One is qualifying for a loan — the minimum a lender will accept. The other is optimizing your purchase — the down payment that gives you the best balance of monthly cost, cash reserves, and long-term interest. The 20% figure speaks only to the second idea, and even then it's not a hard line. Plenty of financially healthy buyers deliberately put less down and invest or save the difference.
The real minimums by loan type
Down payment minimums depend heavily on which loan you use. Here's a plain-English snapshot of the most common options for US buyers:
| Loan type | Typical minimum down | Good to know |
|---|---|---|
| Conventional | 3% | Lowest options usually for first-time or income-qualified buyers; PMI applies under 20% down |
| FHA | 3.5% | Flexible credit requirements; has its own mortgage insurance (MIP) with stickier rules |
| VA | 0% | For eligible veterans and service members; no PMI, but has a funding fee |
| USDA | 0% | For eligible rural and some suburban areas, with income limits |
Exact eligibility, fees, and credit requirements change over time and vary by lender, so treat these as starting points and confirm current details with a loan officer. The headline takeaway stands: 3% to 3.5% down is a real path for many buyers, and some borrowers qualify for zero down.
The PMI tradeoff: less down, more monthly cost
Putting less than 20% down on a conventional loan means you'll pay PMI — an extra monthly charge that protects the lender, not you. It typically runs somewhere from a fraction of a percent up to about 1% of the loan amount per year. On a $300,000 loan that can be roughly $100 to $200 a month until you build enough equity.
So a smaller down payment has two costs: a bigger loan balance (and therefore a higher base payment) plus PMI on top. The upside is you keep more cash and can buy sooner. PMI is also temporary on conventional loans — once you reach 20% equity you can request removal. If you want to see what insurance might cost at your down payment, our PMI calculator can estimate it.
How to choose the right down payment for you
There's no universally "correct" number. The best down payment balances three things: the home you want, the monthly payment you can sustain, and the cash you need to keep in reserve. Some honest tradeoffs to weigh:
- More down lowers your monthly payment, avoids or shortens PMI, and may get you a slightly better rate — but it ties up cash you might need for emergencies, moving, or repairs.
- Less down lets you buy sooner and keep a healthy savings cushion — but it means a larger loan, PMI for a while, and more interest paid over time.
- Don't forget closing costs. These typically run 2% to 5% of the price and are separate from your down payment, so budget for both.
- Keep an emergency fund. Emptying savings to reach 20% is rarely worth it if it leaves you with no buffer the day a water heater fails.
A useful exercise is to model a few down payment amounts side by side. Our down payment calculator shows how 3%, 5%, 10%, and 20% change your loan size and cash needed, and the mortgage calculator shows the resulting monthly payment.
A timeline for saving
Once you pick a target, saving becomes a math problem. Suppose you're eyeing a $300,000 home. Here's roughly what different targets require, before closing costs:
| Down payment | Amount on $300,000 | PMI on conventional? |
|---|---|---|
| 3% | $9,000 | Yes |
| 5% | $15,000 | Yes |
| 10% | $30,000 | Yes |
| 20% | $60,000 | No |
If you can set aside, say, $500 a month, a 5% target ($15,000) takes about two and a half years, while 20% ($60,000) takes ten. That gap is exactly why so many buyers choose a smaller down payment, accept PMI for a few years, and remove it later by building equity. Automating a monthly transfer into a high-yield savings account makes the timeline shorter and more predictable.
The bottom line
You almost certainly don't need 20% down. Many buyers get in with 3% to 5%, pay PMI for a stretch, and drop it once they hit 20% equity. Just make sure your down payment leaves you with a comfortable monthly payment, money for closing costs, and an intact emergency fund. Run a couple of scenarios before you commit so you can see the real tradeoffs in dollars, not just rules of thumb.
