A 20% down payment on a median-priced home requires significant savings. Here's how to calculate your target, where to save, and creative strategies to get.
This guide is designed for first-pass understanding. Start with core terms, then apply the framework in your own account workflow.
Saving for a house down payment feels like trying to hit a moving target. Home prices keep climbing, your savings feel too small, and everyone has an opinion about how much you need. The truth is more nuanced than the old "you need 20%" rule suggests. Depending on your situation, you might need anywhere from 3% to 20%; and the right amount depends on your timeline, market, and financial profile.
You need 3-20% of the home purchase price for a down payment, depending on your loan type. Conventional loans allow as little as 3% down for first-time buyers, FHA loans require 3.5%, and VA loans offer 0% down for veterans. Putting 20% down avoids Private Mortgage Insurance (PMI), but buying sooner with less down can make financial sense when home prices are appreciating. Save your down payment in a high-yield savings account; not stocks — to avoid market risk on a known timeline.
| Loan Type | Min. Down Payment | On a $400K Home | PMI Required? |
|---|---|---|---|
| Conventional | 3-5% | $12,000-$20,000 | Yes (below 20%) |
| FHA | 3.5% | $14,000 | Yes (MIP) |
| VA | 0% | $0 | No |
| USDA | 0% | $0 | Guarantee fee |
On a $400,000 home, 20% is $80,000. But 5% is only $20,000, and 3% is $12,000. The question is whether the PMI cost is worth getting into a home sooner versus waiting to save the full 20%.
Putting 20% down has real advantages:
The traditional target is 20% to avoid PMI. On a $400K home, that's $80K. However, many loans allow 3-5% down (FHA: 3.5%, conventional: 3%). Factor in closing costs (2-5% of purchase price) and a cash reserve for emergencies after closing.
Use a high-yield savings account or short-term CDs. If your timeline is under 3 years, avoid investing in stocks — a market downturn could delay your home purchase. For 3-5+ year timelines, a conservative portfolio (80% bonds, 20% stocks) may be appropriate.
Many states offer down payment assistance programs, below-market interest rates, and tax credits for first-time buyers. FHA loans require just 3.5% down with a 580+ credit score. VA loans offer 0% down for veterans. Research programs in your state — thousands of dollars in assistance often go unclaimed.

What Are Closing Costs? Fees, Negotiation, and What to Expect
On the other hand, waiting years to save 20% has real costs:
This is critical: do not invest your down payment in stocks. Your down payment savings need to be in safe, liquid vehicles. The stock market can drop 30% in a year. If that happens six months before you're ready to buy, your $80,000 becomes $56,000 and your timeline is destroyed.
Your timeline determines how aggressively you can save and where to put the money:
Aggressive savings mode. Cut discretionary spending to the bone. Put everything in a HYSA — you need maximum liquidity and zero risk. Calculate your monthly savings target: if you need $40,000 and have $16,000 saved, you need $2,000 per month for the next 12 months. If that's not achievable, adjust your target home price or timeline.
The sweet spot for most first-time buyers. You have time to build a solid savings habit without the exhaustion of a sprint. Consider a CD ladder: put one-third in a 1-year CD, one-third in a 2-year CD, and one-third in a HYSA. As each CD matures, roll it into the HYSA as you approach your purchase date.
You have more flexibility, but resist the temptation to invest in stocks. Even with a 5-year horizon, the risk of a major downturn right before you need the money is too high. If you absolutely want some market exposure, keep at least 80% in safe assets and limit the rest to a conservative balanced fund.
Before you fixate on a down payment number, make sure you can actually afford the house. Lenders use the 28/36 rule:
On a $100,000 household income, 28% means a maximum housing cost of $2,333 per month. Work backward from there: at 6.5% interest with 20% down, that supports roughly a $350,000-375,000 home (depending on taxes, insurance, and HOA in your area).
Clarity makes this calculation easy. By tracking your income and all debt payments, you can see your actual debt-to-income ratio and calculate precisely what mortgage payment fits your budget.
First-time buyers are often shocked by how much cash they need beyond the down payment. Budget for these:
In total, on a $400,000 home with 20% down, you might need $80,000 (down payment) + $15,000 (closing costs) + $8,000 (moving and initial expenses) = $103,000 in cash before you account for your emergency fund.
Thousands of down payment assistance (DPA) programs exist at the federal, state, and local level. These include:
Check your state's housing finance agency website and HUD.gov for programs in your area. Eligibility usually depends on income, purchase price, and first-time buyer status (which includes anyone who hasn't owned a home in the last three years).
Beyond down payment assistance, several programs specifically help first-time buyers:
Start by defining your target: what price range are you shopping in, and what down payment percentage makes sense for your situation? Use Clarity to track your current savings rate and project when you'll hit your target. Open a dedicated high-yield savings account labeled "house fund" and set up automatic transfers. Run the 28/36 calculation with your actual income and debts to confirm your price range is realistic. Then research down payment assistance programs in your state — you might qualify for grants or forgivable loans that dramatically shorten your timeline. The sooner you start saving with a clear target, the sooner you'll be ready to make an offer.
