The down payment is your starting point, but not the whole picture

The amount you need to save depends on three separate costs: the down payment, closing costs, and reserves for emergencies after you buy. Most buyers put down between 3 and 20 percent of the home's purchase price, though the exact percentage affects your monthly payment and whether you pay mortgage insurance. Closing costs typically run 2 to 5 percent of the purchase price. Beyond that, lenders want to see you have cash left over — usually enough to cover two to six months of mortgage payments, property taxes, insurance, and maintenance.

The math changes based on the home price in your area, your income, and how much you can borrow. A $300,000 home with a 10 percent down payment requires $30,000 down plus $6,000 to $15,000 in closing costs, plus several thousand more in reserves. A $500,000 home with the same 10 percent down payment requires $50,000 down plus $10,000 to $25,000 in closing costs. The total you need to save is not a fixed number — it scales with the price of the home you are targeting.

Key Takeaways

  • Down payments range from 3 to 20 percent of the home price, and a smaller down payment means you will pay mortgage insurance on top of your regular payment.
  • Closing costs add 2 to 5 percent of the purchase price on top of your down payment and are due at signing, not rolled into the loan.
  • Lenders expect you to have emergency reserves after closing — typically two to six months of housing costs — so you cannot save only the down payment and closing costs.
  • Your actual target depends on the home price in your area and how much you can afford to borrow based on your income and debt.
  • The lower your down payment, the higher your monthly payment and the more you pay in interest over the life of the loan.

Breaking down the down payment by percentage

A 3 percent down payment is the minimum on most conventional loans and is common for first-time buyers. It requires the least upfront cash but triggers private mortgage insurance (PMI), which adds roughly 0.5 to 1 percent of the loan amount to your monthly payment. You pay PMI until you reach 20 percent equity in the home, which can take 10 to 15 years depending on how fast home values rise and how much extra you pay toward principal. On a $300,000 home, 3 percent down is $9,000; on a $500,000 home, it is $15,000.

A 10 percent down payment reduces but does not eliminate PMI. You still pay mortgage insurance, though at a lower rate than with 3 percent down. The tradeoff is that you save more cash upfront before buying, which takes longer but costs less per month once you own the home. On a $300,000 home, 10 percent is $30,000; on a $500,000 home, it is $50,000.

A 20 percent down payment eliminates PMI entirely and is the threshold most lenders consider the "safe" zone. It requires the most cash upfront but saves you thousands in insurance premiums over time. On a $300,000 home, 20 percent is $60,000; on a $500,000 home, it is $100,000. Many buyers aim for this target if they can reach it, because the monthly savings from avoiding PMI add up quickly.

Closing costs are separate from the down payment

Closing costs cover the lender's fees, title search, appraisal, inspections, insurance, and legal work. They are due at signing and cannot be borrowed as part of your mortgage (with rare exceptions). The total usually falls between 2 and 5 percent of the purchase price, though the exact amount depends on your location, the lender, and the title company.

On a $300,000 home, closing costs typically range from $6,000 to $15,000. On a $500,000 home, they range from $10,000 to $25,000. Some lenders allow the seller to cover part of closing costs as a negotiation point, which can reduce what you pay out of pocket. Ask your lender for a Loan Estimate within three days of applying — it will show you the exact closing costs for your specific loan and property.

Emergency reserves after closing matter to lenders

Most lenders require you to show cash reserves after closing — money left in the bank after you pay the down payment and closing costs. This reserve typically equals two to six months of your total housing payment, which includes the mortgage principal and interest, property taxes, homeowners insurance, and HOA fees if applicable.

If your total monthly housing cost is $2,000, lenders may want to see $4,000 to $12,000 in reserves remaining. This is not money you must spend; it is money you must have available to show you can weather a job loss or major repair. Some lenders are stricter about this requirement than others, and some programs (like FHA loans) have different reserve rules. Ask your lender what reserve amount they require before you finalize your savings target.

How to calculate your total savings goal

Start by identifying the home price you are targeting in your area. Use recent sales data from Zillow, Redfin, or your local real estate market to find the median price for homes you are interested in. Then work through this calculation:

  1. Multiply the home price by your chosen down payment percentage (3%, 10%, or 20%) to get your down payment amount.
  2. Multiply the home price by 3.5% to estimate closing costs (use 2% for a low estimate, 5% for a high one).
  3. Calculate your estimated monthly housing payment using an online mortgage calculator, then multiply by the number of months of reserves your lender requires (typically 4 to 6 months).
  4. Add all three numbers together to get your total savings target.

Example: You are targeting a $350,000 home with a 10 percent down payment. Down payment: $35,000. Closing costs at 3.5%: $12,250. Monthly housing payment (estimated): $2,400. Reserves for 5 months: $12,000. Total to save: $59,250.

This calculation assumes you are financing the rest through a mortgage. If you plan to pay cash, your target is simply the full purchase price plus closing costs.

Mortgage insurance adds cost if you put down less than 20 percent

Private mortgage insurance (PMI) is required on conventional loans when your down payment is less than 20 percent. The cost varies by lender and loan type but typically ranges from 0.5 to 1 percent of the loan amount per year, paid monthly as part of your mortgage payment.

On a $300,000 home with a 10 percent down payment ($30,000), your loan is $270,000. PMI might cost $1,350 to $2,700 per year, or $112 to $225 per month. That cost continues until you have paid down the loan to 80 percent of the original home value or until you refinance. The lower your down payment, the longer you pay PMI. This is why many buyers choose to save longer and put down 20 percent if they can — the monthly savings from avoiding PMI can be substantial over time.

Saving strategies to reach your target faster

Once you know your number, break it into smaller milestones. If you need to save $60,000 and you have three years, that is roughly $1,667 per month. If you have five years, it is $1,000 per month. Knowing the monthly amount makes the goal feel more manageable.

Use a high-yield savings account for money you will need within the next two to three years. These accounts currently pay 4 to 5 percent annual interest, which is much higher than a regular savings account. Your money stays liquid and accessible, and you earn interest while you save. If your timeline is longer (four years or more), you might split your savings between a high-yield account for the near-term portion and a certificate of deposit (CD) for the portion you will not touch for a year or two. CDs lock your money away but pay slightly higher rates.

Automate your savings by setting up a transfer from your checking account to your savings account on payday. Even $200 or $300 per paycheck adds up over time. Track your progress monthly so you can see the balance growing — this often motivates you to stick with the plan or find ways to save more.

Frequently Asked Questions

Can I borrow money for a down payment?

Most lenders do not allow you to borrow the down payment from another person or credit source, because it increases your debt-to-income ratio and makes the loan riskier. Some first-time buyer programs allow gifts from family members if you document them in writing and the giver signs a statement saying it is a gift, not a loan. Ask your lender about their gift policy before you accept money from anyone.

What if I cannot save 20 percent down?

You can buy with 3 to 10 percent down and pay mortgage insurance. The insurance adds to your monthly payment, but it lets you buy sooner. As your home value rises and you pay down the loan, you can refinance or request PMI removal once you reach 20 percent equity. Many buyers use this path because waiting five years to save 20 percent means missing out on years of building equity and potentially buying at a higher price later.

Should I save for a down payment or pay off debt first?

Lenders look at your debt-to-income ratio, which is your total monthly debt payments divided by your gross monthly income. If your ratio is too high, you will not may have access to for a mortgage no matter how much you have saved. If you have high-interest debt (credit cards, personal loans), paying that down first often makes sense because it lowers your ratio and improves your credit score. Ask a lender to pre-may have access to you so you know whether debt payoff or down payment saving should come first.

Do I need to save closing costs separately from the down payment?

Yes, closing costs are due at signing and are not part of the down payment. However, in some negotiations, the seller agrees to cover part or all of your closing costs. This is more common in a buyer's market. Even if you negotiate seller concessions, it is safer to save the full amount yourself so you are not dependent on the deal going through.

How does a first-time homebuyer program change my savings target?

Some first-time buyer programs offer down payment assistance, lower interest rates, or reduced closing costs. The amount varies by state and local program. Contact your state housing finance agency or a local nonprofit housing counselor to learn what programs exist in your area. These programs can lower your total savings target, but they often have income limits or require you to take a homebuyer education course first.
