Down Payment Calculator

Calculate how long it takes to save for a house down payment. Enter the home price, your target percentage, current savings, and monthly contribution.

Quick Answer

For a $400,000 home with 20% down ($80,000), saving $1,500/month from $25,000 in existing savings takes about 3 years. With a high-yield savings account at 4.5%, you'll get there a few months sooner.

About This Tool

The Down Payment Calculator helps you figure out how long it will take to save enough for a house down payment. Enter the home price, your desired down payment percentage, how much you've already saved, and how much you can save each month. The calculator factors in interest earned on a high-yield savings account and shows milestones for common down payment percentages.

Down Payment Percentages Explained

The traditional 20% down payment avoids private mortgage insurance (PMI), but it's not the only option. FHA loans require just 3.5% down with a credit score of 580+. Conventional loans now go as low as 3% down for first-time buyers. VA loans offer 0% down for veterans. Each option has trade-offs: lower down payments mean higher monthly payments, PMI costs, and more interest paid over the loan's life.

The Real Cost of a Smaller Down Payment

Putting less down doesn't just add PMI. On a $400,000 home, the difference between 10% down ($40,000) and 20% down ($80,000) means borrowing an extra $40,000. At 7% over 30 years, that extra borrowing costs about $95,800 in total payments — more than double the original $40,000. Plus PMI of roughly $200-300/month until you reach 20% equity. But if home prices are rising 5-10% per year, waiting 2-3 extra years to save may cost more than the PMI.

Strategies to Save Faster

Open a high-yield savings account (currently 4-5% APY) for your down payment fund. Automate transfers on payday so saving happens before spending. Consider temporarily reducing discretionary expenses. Side income — freelancing, selling unused items, or a part-time gig — can accelerate your timeline dramatically. Some states offer down payment assistance programs worth $5,000-$25,000 for qualifying buyers.

Don't Forget Closing Costs

Your down payment isn't the only upfront cost. Budget an additional 2-5% of the home price for closing costs — appraisal fees, title insurance, origination fees, attorney costs, and prepaid items like property taxes and homeowner's insurance. On a $400,000 home, that's $8,000-$20,000 on top of your down payment. Some of these costs are negotiable, and sellers sometimes contribute toward buyer closing costs.

Frequently Asked Questions

How much do I need for a down payment on a house?
It depends on the loan type. Conventional loans typically require 5-20%, with 20% being ideal to avoid private mortgage insurance (PMI). FHA loans require as little as 3.5% down. VA and USDA loans offer 0% down for eligible borrowers. On a $400,000 home, 20% is $80,000, 10% is $40,000, and 3.5% (FHA) is $14,000.
What is PMI and how do I avoid it?
Private Mortgage Insurance (PMI) is required on conventional loans when your down payment is less than 20%. PMI typically costs 0.5-1.5% of the loan amount annually ($1,500-$4,500/year on a $300,000 loan). You can avoid it by putting 20% down, choosing an FHA loan with its own mortgage insurance, or using a piggyback loan (80/10/10). PMI is automatically removed when you reach 22% equity.
Should I save for a 20% down payment or buy sooner with less?
There's no universal answer. Putting 20% down avoids PMI, gives you lower monthly payments, and often gets you a better interest rate. But in a rising market, waiting to save 20% means paying a higher purchase price later. Some buyers do better buying at 5-10% down and building equity through appreciation. Run the numbers for your specific market and timeline.
What other costs do I need besides the down payment?
Closing costs typically run 2-5% of the home price ($8,000-$20,000 on a $400,000 home). You'll also want an emergency fund (3-6 months of expenses), moving costs, and potentially money for immediate repairs or furnishing. A good rule: save your down payment plus an additional 3-5% for closing costs and reserves.
Where should I keep my down payment savings?
For money you'll need within 1-3 years, high-yield savings accounts or CDs are the safest options. They're FDIC-insured and offer 4-5% APY in the current rate environment. Avoid investing down payment savings in stocks — a market downturn right before your purchase could set your timeline back significantly. Treasury bills or money market funds are also good options for short-term savings.
