How Much Down Payment Do You Really Need?

"You need 20% down to buy a house" is one of the most expensive myths in personal finance. It keeps people renting for years longer than they need to, waiting to save a pile of cash that most loan programs don't actually require. The truth is that the minimum down payment for many buyers is far lower — sometimes zero — and the right down payment is a separate decision that depends on your savings, your monthly budget, and what you're trying to optimize.

This guide separates those two questions. First, the floor: what each loan type actually requires. Then the real choice: how much you should put down once you know you have options. We'll use concrete numbers throughout so you can see exactly what each extra percentage point costs and buys.

What each loan type actually requires

The minimum down payment depends entirely on the loan program. Here's where the real floors sit as of 2026:

Conventional loans — as low as 3%

Conventional loans (the kind backed by Fannie Mae and Freddie Mac) allow first-time buyers to put down as little as 3%. On a $400,000 home, that's $12,000 — not $80,000. You'll pay private mortgage insurance until you reach 20% equity, but you're in the door far sooner. Repeat buyers typically need 5%.

FHA loans — 3.5% down

FHA loans, backed by the Federal Housing Administration, require 3.5% down if your credit score is 580 or higher (and 10% if it's between 500 and 579). FHA is popular with buyers who have thinner credit or a higher debt-to-income ratio, because FHA guidelines are more forgiving. The trade-off is FHA mortgage insurance, which works differently from conventional PMI and is harder to cancel — we compare the two in FHA vs conventional.

VA and USDA loans — 0% down

If you qualify, these are the closest thing to a free lunch in mortgages. VA loans, for eligible veterans and service members, require no down payment and no monthly mortgage insurance — see VA loans explained. USDA loans, for buyers in eligible rural and suburban areas, are also zero down. Both have specific eligibility rules, but if you fit, you can buy with closing costs alone.

Jumbo loans — usually 10–20%

If you're borrowing above the conforming loan limit (over roughly $806,500 in most of the country in 2026, higher in expensive areas), lenders typically want 10% to 20% down because they're keeping more risk on their own books.

So before you assume you can't afford to buy, find out which programs you qualify for. The minimum is often a fraction of what you've been told.

What a bigger down payment actually buys you

If you can put more down, what do you get for it? Four concrete things.

1. A smaller loan and a lower payment. Every dollar you put down is a dollar you don't borrow or pay interest on. On a 30-year loan at 6.5%, each additional $10,000 down lowers your monthly principal and interest by about $63.

2. No PMI at 20% down. This is the big one for conventional buyers. Cross the 20%-down threshold and you skip private mortgage insurance entirely, which can run $100 to $300+ a month. We cover exactly how that works in PMI explained.

3. A better interest rate. Lenders price risk. A bigger down payment means more "skin in the game," and many lenders offer slightly better rates at lower loan-to-value ratios. Check current 30-year rates and ask each lender how their pricing changes at 5%, 10%, and 20% down.

4. A stronger offer. In a competitive market, sellers sometimes favor buyers with more cash down, viewing the deal as less likely to fall through at appraisal.

A worked example: 5% vs 20% down

Let's make this real. Say you're buying a $400,000 home with a 30-year loan at 6.5%.

Option A — 5% down ($20,000):

• Loan amount: $380,000
• Principal and interest: about $2,402/month
• PMI at roughly 0.6%/year: about $190/month
• Total: about $2,592/month (before taxes and insurance)

Option B — 20% down ($80,000):

• Loan amount: $320,000
• Principal and interest: about $2,023/month
• PMI: $0
• Total: about $2,023/month (before taxes and insurance)

The 20%-down buyer pays about $569 less per month. But they also handed over $60,000 more upfront. The 5%-down buyer kept that $60,000 — which might be the difference between buying this year and buying in five years, and which could stay invested or sit as an emergency fund.

Plug your own numbers into the mortgage calculator and slide the down payment up and down to watch the monthly payment and PMI move in real time. It makes the trade-off concrete in a way a table never will.

The case for putting less down

It feels responsible to put as much down as possible, but draining your savings can backfire. Consider keeping more cash if:

• It would wipe out your emergency fund. A house comes with surprise costs — a failed HVAC, a roof, a plumbing emergency. Being "house rich and cash poor" is genuinely dangerous. Most planners suggest keeping three to six months of expenses liquid after closing.
• You'd skip closing costs in your math. Closing costs typically run 2–5% of the loan amount, separate from your down payment. On that $400,000 home, budget another $8,000–$15,000. Don't put every dollar into the down payment and get surprised at the table — see closing costs explained.
• You could invest the difference for more than your mortgage rate. This is a judgment call, not a guarantee, but if your mortgage is at 6.5% and you'd otherwise invest long-term, some buyers reasonably choose to put less down and keep more invested.
• PMI is cheap for you. With strong credit, PMI might cost well under 0.5% a year — and it's cancelable once you hit 20% equity, so it's a temporary cost, not a permanent one.

The case for putting more down

On the other side, lean toward a larger down payment if:

• You'll still have a healthy cash cushion afterward. If you can put 20% down and keep your emergency fund, doing so locks in a lower payment and skips PMI.
• You want the lowest possible payment. A bigger down payment is the most direct lever for shrinking your monthly obligation, which matters if your debt-to-income ratio is tight.
• You're risk-averse about your housing cost. A smaller loan is simply less debt hanging over you.

There's no universal right answer. The best down payment is the largest one that doesn't leave you cash-strapped after closing.

How to land on your number

Put it together in four steps:

1. Find your floor. Identify which loan programs you qualify for and their minimums — often 3%, 3.5%, or even 0%.
2. Protect your cushion. Decide the minimum cash you want left after closing (emergency fund + closing costs). That's money the down payment can't touch.
3. Run the trade-off. In the mortgage calculator, compare your payment and PMI at a few down payment levels — say 5%, 10%, and 20% — using a realistic rate from the current rates page.
4. Pick the largest comfortable number. Choose the most you can put down while keeping your cushion intact and your monthly payment in range.

The bottom line

You almost certainly need far less than 20% down to buy a home — as little as 3% on a conventional loan, 3.5% with FHA, and nothing at all with a VA or USDA loan if you qualify. A bigger down payment lowers your payment, can eliminate PMI, and may earn you a better rate, but only if it doesn't leave you without a safety net. Find your minimum, protect your emergency fund and closing costs, then put down the most you comfortably can. Run a few scenarios through the calculator before you commit — the right down payment is the one that gets you into the home and lets you sleep at night.
