How much cash do I need to close?

Two inputs: the price and the down payment percent. The calculator returns the check you write at closing: the down payment, plus closing costs from Freddie Mac's published 2% to 5% range, plus any discount points, minus seller credits and minus the earnest money you already deposited. Put down less than 20% and it also quantifies the consequence: the mortgage insurance the smaller down payment adds to the monthly payment, and when the law makes it end.

What cash to close is

Cash to close is everything you wire or bring as a cashier's check on closing day: the down payment, plus the one-time costs of getting the loan and transferring the home, minus whatever the seller agreed to credit you and minus the deposit you already made. At the defaults, with no credits and no deposit entered, that is $80,000 down on a $400,000 price plus $14,000 of closing costs, a check of $94,000. Discount points, if you buy the rate down, join the costs side: a point is 1% of the loan, so it prices off the amount you borrow, not the price of the house.

The model has one hard rule, and it is the one people get wrong: seller credits offset closing costs and points, never the down payment. The down payment is equity you are required to bring; the credits can only shrink the fee side of the check. With $10,000 of credits at the defaults the check falls to $84,000, and a credit larger than the costs stops there. The warning under the result reports the unusable excess when you cross that line.

The deposit is the other subtraction, and it is the one people forget. Earnest money paid when the offer was accepted is credited at closing: the CFPB's mortgage key terms describe it as money that may be applied to closing costs or the down payment once the sale is finalized. It is not an extra cost and it is not free money; it is part of this check, paid early. Enter $10,000 of earnest money at the defaults and the $94,000 the purchase takes leaves $84,000 to bring on closing day. The composition figure carries it as its own row, so the parts always add up to the number above them.

Every figure on this page and in the JSON twin comes from one function, so the two never drift. The closing-cost default is a published range's midpoint, not a guess; the price and down payment are examples to be replaced.

What closing costs contain

The closing-cost estimate is one percentage standing in for a stack of line items. The stack has four broad layers: lender fees (origination, underwriting, the credit pull), title work (the search, settlement, and title insurance), third-party reports (the appraisal, sometimes a survey or inspection the lender requires), and prepaids (property tax and homeowners insurance paid into escrow at closing, plus interest for the days before your first payment).

Freddie Mac puts the total at 2% to 5% of the purchase price. On a $400,000 home that is $8,000 to $20,000; the default here is the middle of the range, $14,000. Where you land inside it depends mostly on your state's taxes and title customs and on the lender's fees, which is why the rate is an adjustable assumption rather than a constant. When your Loan Estimate arrives, enter its actual total as a percent of the price and the check updates.

Putting down less than 20 percent

The down payment percent is the biggest lever on the check, and it prices a real decision. Dropping from 20% to 10% down on the default price cuts the check from $94,000 to $54,000, keeping $40,000 in your pocket on closing day.

The consequence is monthly. The loan grows to $360,000, and a conventional loan under 20% down requires private mortgage insurance, which Freddie Mac puts at 0.36% to 0.84% of the loan per year. At the mid-range 0.6% that is about $180 a month here, on top of the larger principal-and-interest payment the bigger loan carries.

PMI is not forever. Under the Homeowners Protection Act, as the CFPB explains it, you can request cancellation once the balance reaches 80% of the home's original value, and the servicer must terminate it automatically when the balance is scheduled to reach 78%. The trade the calculator lets you price is cash now against a removable monthly cost; whether it is worth it depends on what the kept cash would otherwise do.

What the calculator does not know

What a point buys. The calculator prices the cost of a discount point exactly, 1% of the loan, but the rate reduction a point purchases varies by lender, loan, and day. Pricing that trade needs the two quotes side by side; this page prices the upfront side only.

Your state and your contract. Transfer taxes and recording fees differ enormously by state and city, which is most of the spread inside the 2% to 5% range. Prorations, where the buyer and seller split the current property tax bill or HOA dues at the closing date, shift the check in either direction. Both are in your Loan Estimate and Closing Disclosure, not in a national default.

Your contract's fine print. The deposit is an input here, but whether you keep it if the deal falls through is a contract question rather than an arithmetic one: it turns on the contingencies you negotiated into the offer. And lender-specific rules, like the cap on seller contributions for your loan program, can bind before this model's arithmetic does.

For agents and scripts

This calculator is built to be used without a browser. Every input is a query parameter on this page, and the same parameters on the JSON twin return the complete answer as a document.

GET /tools/cash-to-close.json?price=550000&downPct=10

The response carries inputs after parsing and clamping, result with the down payment, the loan and its loan-to-value, closing costs, points, the credits applied, the cashRequired total the purchase takes, the cashToClose check left after the deposit already paid, and the monthly mortgage insurance a down payment under 20% adds, plus sensitivity tables by down payment percent and closing-cost rate, drivers ranked by effect with a plain sentence each, assumptions that say for every field whether you supplied it and name the source when the default came from one, sources with a URL and an as-of date for each source the tool cites, which is an empty list on the calculators whose every default is an example input rather than a published figure, warnings, a disclaimer, and in tool the canonicalUrl and jsonUrl that carry only your non-default parameters. The canonical URL is the answer's permanent address; use it when you cite the number.

Parameters, all optional, in any order:

  • price ($), default $400,000.
  • downPct (%), default 20%.
  • closingRate (%), default 3.5%, from Freddie Mac, What are closing costs and how much will I pay?.
  • points (%), default 0%.
  • sellerCredits ($), default $0.
  • earnestMoney ($), default $0.

Values accept plain numbers and loose human formats such as 100k, $100,000, or 6.5%. Unknown parameters are ignored, values outside a field's range are clamped and reported in warnings, and the endpoint never fails on bad input. Responses are cacheable for a day; the defaults change when their sources publish, and tool.version changes when the method does.

Common questions

How much cash do I need for a $400,000 house?

At 20% down with closing costs at the published mid-range 3.5% of the price, the purchase takes $94,000: $80,000 of down payment plus $14,000 of closing costs. That is the whole number, not the closing-day wire: earnest money you already deposited is credited at closing, so entering a $10,000 deposit leaves $84,000 to bring that day. At 10% down the check falls to $54,000, but the smaller down payment adds mortgage insurance of about $180 a month to the payment. Enter your own price and the page recomputes as you type.

What is the difference between closing costs and cash to close?

Closing costs are the one-time fees of getting the loan and transferring the home: $14,000 at the defaults, 3.5% of the $400,000 price. Cash to close is the whole check: those costs plus the down payment, plus any discount points, minus any seller credits and minus the earnest money you already deposited. The down payment is by far the larger part at most down payment levels, which is why the check moves so much more with the down percent than with the fee estimate.

Can the seller pay my closing costs?

Yes, through seller credits negotiated into the contract, and this calculator models them with one floor: credits offset closing costs and points, never the down payment. With $10,000 of credits at the defaults, the check drops from $94,000 to $84,000. Lenders also cap what a seller may contribute, and the cap varies with the loan program and the size of the down payment, so a large credit may not be fully usable; ask the lender for the cap on your loan.

Does earnest money count toward the down payment?

When the sale closes the deposit stops being separate money. The CFPB's mortgage key terms put it plainly: once the sale is finalized, the earnest money "may be applied to closing costs or the down payment." Either way it is money this purchase already took, so the calculator credits it against the check instead of adding to it. At the defaults the purchase takes $94,000; enter a $10,000 deposit and $84,000 is left to bring on closing day. Whether you keep the deposit if the deal falls apart is a contract question rather than an arithmetic one: it turns on the contingencies written into your offer.

Are discount points worth it?

The calculator prices the side of that trade it can know: one point costs 1% of the loan, $3,200 at the defaults, paid at closing on top of the down payment and closing costs. What a point buys is the side it cannot: the rate reduction varies by lender and by day, so there is no universal answer. Get the with-points and without-points quotes from the same lender on the same day, then weigh the upfront cost here against the monthly difference over the years you expect to keep the loan.

What happens if I put less than 20 percent down?

Two things move in opposite directions. The check shrinks: $54,000 at 10% down against $94,000 at 20% on the default price, keeping $40,000 in your pocket. And the monthly payment grows, because the loan is bigger and a conventional loan under 20% down adds private mortgage insurance, about $180 a month here at Freddie Mac's mid-range 0.6% rate. Under the Homeowners Protection Act you can request cancellation at 80% loan-to-value, and the servicer must end it automatically at 78%.

Can an agent or a script use this calculator?

Yes. Every input is a query parameter, and the same parameters on /tools/cash-to-close.json return the full answer as JSON: inputs, the down payment, loan, closing costs, points, applied credits, the cash the purchase takes, the cash to close after your deposit, the monthly mortgage insurance a low down payment adds, drivers, sensitivity tables by down payment percent and closing-cost rate, assumptions with sources, and warnings. No browser, no API key.
