Down Payment Calculator
Find your down payment, loan amount, and whether you'll owe PMI from a home price and percentage.
Example
On a $400,000 home with a 10% down payment: down payment = 400,000 × 0.10 = $40,000.00, loan amount = 400,000 − 40,000 = $360,000.00, and loan-to-value = 90%. Because 10% is below 20%, PMI typically applies. Reaching 20% would mean putting down $80,000 and financing $320,000 with no PMI.
How it works
Enter a home price and either a down payment percentage or a dollar amount; the calculator derives the other value, your loan balance, and your loan-to-value ratio. If you put down less than 20%, it flags that private mortgage insurance (PMI) typically applies.
Good to know
This Down Payment Calculator turns a home price into the three numbers that drive a mortgage application: the cash you'd put down, the loan you'd finance, and your loan-to-value (LTV) ratio. You can work in either direction — enter a percentage to see the dollar amount, or enter a dollar amount to see the percentage it represents. It's aimed at first-time buyers, anyone saving toward a target down payment, and people comparing how different deposit sizes change their financing.
Reach for it when you're sizing up a specific listing, deciding how much of your savings to commit, or trying to figure out how much more you'd need to clear the 20% mark. Because it solves both directions, you can also flip it around: type the cash you actually have into the dollar field and it tells you what percentage that buys you on a given price.
To read the result, look at the loan-to-value figure and the PMI badge together. LTV is just the financed loan divided by the price; at exactly 20% down your LTV is 80%, and the tool switches from "PMI likely required" to "No PMI required." The two bars show, at a glance, how the price splits between your cash and the bank's money — a small down payment leaves a long "Loan (financed)" bar, which is the balance interest accrues on.
One caveat worth keeping in mind: this is a pure price-versus-deposit split. It does not include closing costs, escrow, taxes, insurance, or the monthly mortgage payment, and the 20% PMI rule it flags is the conventional-loan convention — FHA, VA, and other programs handle mortgage insurance differently. Treat the output as a planning estimate, not a quote, and confirm the actual cash-to-close figure with your lender.
Frequently asked questions
At what down payment does PMI go away?
Most conventional lenders require private mortgage insurance when your down payment is under 20% of the price (loan-to-value above 80%). Put down 20% or more and PMI is generally not required. This tool flags the 20% threshold; specific loan programs (like FHA or VA) follow different rules.
Does this include closing costs or property taxes?
No. It calculates only the down payment, the resulting loan amount, and your loan-to-value ratio. Closing costs, escrow, taxes, and insurance are separate and not deducted from or added to these figures.

People also ask
How much is a 20% down payment on a $400,000 house?
Twenty percent of $400,000 is $80,000, leaving a financed loan amount of $320,000 and a loan-to-value ratio of 80%. At that level conventional lenders generally do not require PMI.
Is it better to put down 10% or 20%?
A larger down payment lowers your loan balance, your loan-to-value ratio, and typically removes PMI, but it ties up more cash up front. The right balance depends on your savings, other costs, and your overall financial situation, which this tool does not assess.
What is loan-to-value (LTV) ratio?
LTV is the financed loan amount divided by the home's price, expressed as a percentage. A 20% down payment produces an 80% LTV; the smaller your down payment, the higher your LTV.
Can I buy a house with less than 20% down?
Yes — many conventional and government-backed loans allow down payments well below 20%. The main trade-off on a conventional loan is that private mortgage insurance usually applies until you reach 20% equity.
How do I calculate a down payment from a dollar amount instead of a percent?
Divide the dollar amount you plan to put down by the home price and multiply by 100. This calculator's dollar mode does this automatically and shows the matching percentage and loan amount.
Does a bigger down payment lower my monthly mortgage payment?
Generally yes, because you finance a smaller loan and may avoid PMI, both of which reduce the monthly cost. This calculator shows the loan amount but does not compute the monthly payment itself.
What loan amount will I have after my down payment?
The loan amount is simply the home price minus your down payment. For example, $400,000 minus an $80,000 down payment leaves a $320,000 loan.
