How Long Does It Take to Save a Down Payment? A Table by Price
Short answer: to save a down payment on a $400,000 home, a 10% down payment of $40,000 takes about 3.2 years at $1,000 a month and a 20% down payment of $80,000 takes about 6 years at $1,000 a month (assuming savings earn 4%). To reach $80,000 in five years you would need about $1,207 a month. The smaller the percentage you put down, the sooner you can buy, but the more you borrow.
Key takeaways
- Divide the down payment by what you can save each month, then adjust for interest. The table below does it for four common down payments.
- Putting down 20% avoids private mortgage insurance on a conventional loan, but it is not required. Many buyers put down 3.5% to 10%.
- Budget for closing costs and a moving and repairs fund on top of the down payment.
- Keep the savings in an account that is safe and easy to reach, not in investments that can fall just before you buy.
How many years does each down payment take?
The table assumes a $400,000 home, a savings account paying 4% (an illustration, since rates change), and a steady monthly deposit starting from zero.
| Down payment | Amount | At $500 a month | At $1,000 a month | At $1,500 a month |
|---|---|---|---|---|
| 3.5% (FHA minimum) | $14,000 | 2.3 years | 1.2 years | 0.8 years |
| 5% | $20,000 | 3.2 years | 1.7 years | 1.2 years |
| 10% | $40,000 | 6.0 years | 3.2 years | 2.2 years |
| 20% | $80,000 | 10.8 years | 6.0 years | 4.2 years |
Doubling the monthly deposit cuts the time by about half (from 10.8 to 6.0 years for a 20% down payment). The longer the road, the more the answer depends on your income growing, so a long timeline is better treated as a starting estimate than a promise.
How much do you need to save each month to buy in 3 or 5 years?
| Down payment | Amount | Monthly for 3 years | Monthly for 5 years |
|---|---|---|---|
| 3.5% | $14,000 | $367 | $211 |
| 5% | $20,000 | $524 | $302 |
| 10% | $40,000 | $1,048 | $603 |
| 20% | $80,000 | $2,095 | $1,207 |
These are the deposits that would reach each target at an assumed 4% a year. For a different price, scale the amount: a $250,000 home needs 62.5% of these figures, and a $600,000 home needs 150%.
What does a smaller down payment cost?
A lower down payment means a bigger loan, a higher monthly payment and, on most conventional loans, private mortgage insurance (PMI) until you reach about 20% equity. Government-backed loans have their own insurance rules. A smaller down payment can still be the right call if it gets you into a home sooner and you can afford the payments. The effect of the choice on your budget is easier to see with numbers than with rules of thumb. For the full discussion, read whether 20% down is always necessary, and for the income that supports a price, what income you need for a $500,000 house.
What else do you need besides the down payment?
- Closing costs. Lender, title and other fees are commonly a few percent of the loan, so on a $400,000 purchase that can be thousands of dollars. Ask a lender for a written estimate.
- Moving and set-up costs. Furniture, tools, deposits and a move.
- A repairs fund. Owners pay for roofs and boilers, and landlords no longer do. See the hidden costs of buying a house.
- Your emergency fund. Keep it separate, so a job gap does not force a sale. See how to build an emergency fund.
How do you save a down payment faster?
- Set the target and date. Use the tables above, and a real number turns a wish into a plan.
- Open a separate account and automate a transfer on payday. See savings accounts, CDs and Treasury bills compared.
- Lower the target. A cheaper home or a lower percentage shortens the road.
- Raise income or cut a big cost. Rent, transport and food hold most budgets. See how to lower your monthly bills.
- Send windfalls to it. A bonus or tax refund can remove months. See what to do with a windfall or bonus.
- Check programmes. Many states and lenders offer first-time buyer help. Eligibility changes, so check current offers.

Frequently asked questions
How long does it take to save a down payment?
On a $400,000 home, saving $1,000 a month at an assumed 4% takes about 3.2 years for a 10% down payment and about 6 years for 20%. A 3.5% down payment takes about 1.2 years at the same deposit.
How much should I save each month for a down payment?
Divide the target by the months you have. To reach $40,000 in five years at an assumed 4%, you need about $603 a month. For $80,000 in five years the figure is about $1,207 a month.
Do I need 20% down to buy a house?
No. Many buyers put down 3.5% to 10%. A conventional loan with less than 20% down usually adds private mortgage insurance, and government-backed loans have their own insurance rules.
Where should I keep my down payment savings?
In a safe, easy-to-reach account such as a high-yield savings account, CD or Treasury bills, not in the stock market, where a fall could come just before you need the money.
What costs come on top of the down payment?
Closing costs, moving and set-up costs, and a repairs fund. Closing costs are commonly a few percent of the loan, so ask your lender for a written estimate early, and keep your emergency fund separate.
