Down Payment Calculator

The down payment on a home is calculated as Home Price x (Down Payment Percentage / 100). For a $400,000 home with 20% down, the estimated down payment is $80,000, leaving an estimated loan amount of $320,000. Adding estimated closing costs (typically 2% to 5% of the home price) gives the total cash needed at closing. Enter the home price, down payment percentage, and closing cost percentage to see a full breakdown. If the down payment is below 20%, private mortgage insurance (PMI) is typically required.

Quick Answer

For a $400,000 home with 20% down and 3% closing costs, the estimated down payment is $80,000, the estimated loan amount is $320,000, estimated closing costs are $12,000, and the estimated total cash needed at closing is approximately $92,000.

Typically 2% to 5% of the home price.

How It Works

This calculator uses straightforward percentage-based formulas to estimate the cash needed to purchase a home:

Down Payment = Home Price x (Down Payment % / 100)

Loan Amount = Home Price - Down Payment

Closing Costs = Home Price x (Closing Cost % / 100)

Total Cash Needed = Down Payment + Closing Costs

Where:

  • Home Price = the purchase price of the property
  • Down Payment % = the percentage of the home price paid upfront
  • Closing Cost % = estimated closing costs as a percentage of the home price (typically 2% to 5%)
  • Total Cash Needed = the total amount you need available at the time of closing

Common Down Payment Amounts

The traditional recommendation is 20% down, which avoids the need for private mortgage insurance (PMI). However, many loan programs accept lower down payments. FHA loans require as little as 3.5% down. Conventional loans may accept 3% to 5% down for qualified buyers. VA and USDA loans may require 0% down for eligible borrowers. Lower down payments mean a larger loan and higher monthly payments.

Private Mortgage Insurance (PMI)

When the down payment is less than 20% of the home price, conventional lenders typically require PMI. This insurance protects the lender if the borrower defaults. PMI usually costs between 0.5% and 1.5% of the original loan amount per year, added to the monthly mortgage payment. PMI can generally be removed once the homeowner reaches 20% equity through payments or appreciation.

Closing Costs

Closing costs cover a range of fees including loan origination, appraisal, title insurance, recording fees, prepaid property taxes, and homeowner’s insurance. The total typically ranges from 2% to 5% of the home price, with the national average around 3%. Some of these costs may be negotiable, and some sellers may agree to cover a portion of closing costs as part of the purchase agreement.

Worked Example

For a $400,000 home with 20% down and 3% estimated closing costs: Down Payment = $400,000 x 0.20 = $80,000. Loan Amount = $400,000 - $80,000 = $320,000. Closing Costs = $400,000 x 0.03 = $12,000. Total Cash Needed = $80,000 + $12,000 = $92,000. Since the down payment is exactly 20%, PMI is not required.

For a $300,000 home with 10% down and 3% closing costs: Down Payment = $300,000 x 0.10 = $30,000. Loan Amount = $300,000 - $30,000 = $270,000. Closing Costs = $300,000 x 0.03 = $9,000. Total Cash Needed = $30,000 + $9,000 = $39,000. Since the down payment is below 20%, PMI is likely required, adding an estimated $112 to $337 per month (0.5% to 1.5% of $270,000 / 12).

Frequently Asked Questions

How much should I put down on a house?
The traditional guideline is 20%, which avoids PMI and results in lower monthly payments. However, many buyers put down less. First-time buyers often use 3% to 10% down payment programs. The right amount depends on your savings, monthly budget, loan program eligibility, and how quickly you want to build equity. This calculator helps illustrate the financial impact of different down payment percentages.
What are closing costs?
Closing costs are fees and expenses paid at the time of closing a real estate transaction. They include loan origination fees, appraisal fees, title search and title insurance, attorney fees, recording fees, prepaid property taxes, and prepaid homeowner's insurance. The total typically ranges from 2% to 5% of the home price.
What is PMI and when is it required?
Private mortgage insurance (PMI) is insurance that protects the lender if you default on your mortgage. It is typically required when the down payment is less than 20% of the home price on a conventional loan. PMI costs between 0.5% and 1.5% of the loan amount annually and is added to your monthly payment. It can usually be canceled once you have 20% equity in the home.
Can I avoid PMI with less than 20% down?
There are a few options. VA loans (for eligible veterans) do not require PMI regardless of down payment. Some lenders offer lender-paid mortgage insurance (LPMI), where a slightly higher interest rate replaces the PMI premium. Piggyback loans (an 80/10/10 structure) use a second mortgage to cover part of the down payment, avoiding PMI on the primary loan. Each option has trade-offs to evaluate.
Does this calculator include all costs of buying a home?
This calculator estimates the down payment, loan amount, closing costs, and total cash needed at closing. It does not include ongoing costs such as monthly mortgage payments, property taxes, homeowner's insurance, HOA fees, maintenance, or repairs. For a full monthly payment estimate, use a mortgage calculator in combination with this tool.
