What a sale actually leaves the seller

Where the price goes before it reaches you

One deduction is proportional and three are not. Commission is a rate on the price, so it grows with every increment negotiated upward — the only part of the deal where a higher price partly pays for itself in the wrong direction. The mortgage payoff, the seller’s closing costs and any concession to the buyer are amounts, fixed in money regardless of what the property fetches.

In practice the payoff dominates everything. In each of the pack’s declared vectors it is larger than the commission, the closing costs and the concession combined, which reflects the plain fact that most sales are mainly the repayment of a loan. It also means the sensitivity of your proceeds to the price is far greater than it looks: the debt does not move when the price does, so every unit of price movement lands almost entirely on the net.

The payoff is not the balance printed on your last statement. It is the lender’s quote to a specific settlement date, carrying interest accrued to that date and whatever administrative or discharge charges the loan attracts. Enter the quote. A scheduled balance is a good sanity check on a quote and a poor substitute for one.

Commission is an input because it is a negotiation, not a law. What agents charge, how it is split, and whether it is shared between sides at all differ by market, by brokerage and by contract, and practice has been moving. The form opens with a placeholder rate to stay usable; overwrite it with the rate in your own agreement. The same applies to the seller closing costs, which are entered as one figure precisely because what a seller pays is not the same anywhere twice.

The calculation also runs backwards. Given a net you must reach — enough to clear the payoff and fund the deposit on the next purchase — it solves for the sale price that produces it. That is usually the more decisive direction, because it converts a personal requirement into a listing decision rather than leaving you to guess and check.

No tax of any kind appears. Gain, exemptions and exclusions, depreciation recapture, withholding on the proceeds: all of it sits outside this figure, and all of it differs by jurisdiction and by circumstance. What this produces is a cash reconciliation at settlement, not a taxable result and not the amount you will ultimately keep.

When this calculation is used

• Deciding whether an offer on the table clears the mortgage and still leaves what you need.
• Testing a concession or a commission rate before agreeing to either.
• Working backwards from the deposit your next purchase demands to the price this sale must reach.
• Seeing how much of an asking price is already spoken for before the negotiation begins.
• Checking the bottom line on a settlement statement against the terms the statement lists.

Worked example

The pack’s declared vectors are three sales with a mortgage still outstanding, at commission rates spread across the range brokerages quote, each carrying seller-side closing costs and two of them a concession to the buyer as well.

In all three, the mortgage payoff is the largest single deduction by a wide margin — larger than the commission, the costs and the concession put together. The commission is the next largest in every case, exceeding the closing costs and the concession combined. What lands as net proceeds is around a third of the sale price in each of the three, and it is worth reading that proportion correctly: it says far more about how much debt these particular sellers still carry than about what selling costs.

Every figure is produced by the certified engine at mount; this page stores none. The pack declares a refusal for a sale with no price, and a warning for proceeds that come out negative — a seller who would have to bring funds to settlement. None of the declared vectors reaches that warning; all three leave the seller with money.

What each input represents

Assumptions and limits

• Commission is a straight percentage of the price — undivided between sides, untiered and without a minimum.
• The payoff is exactly what you enter; the calculation neither derives it from a schedule nor checks it against one.
• Seller closing costs arrive as one figure and are neither itemised nor inferred, because what a seller pays differs by market, by contract and by negotiation.
• Concessions are cash equivalents settled at closing rather than obligations that survive it.
• No tax is computed anywhere: this is a cash reconciliation, not a gain calculation, not an exclusion test and not a withholding estimate.
• Prorations of taxes, association dues and utilities are not modelled; enter their net effect within the closing costs if your settlement statement carries them.

What the guards protect against

• A sale with no price is refused rather than answered — the declared refusal vector pins it — because there are no proceeds from a transfer with no consideration.
• Commission is bounded to a plausible ceiling, and the payoff, the costs and the concession are each held at nothing or above. The calculation subtracts them for you, so none of them should be entered as a negative.
• A negative result is not refused. Owing more than the sale releases is a real situation, so the pack answers it and raises its declared warning that the seller would have to bring cash, rather than pretending the arithmetic is invalid.
• Run backwards, the search for the price that hits a target net is bounded to the same realistic span of prices the forward direction accepts, so a target that no plausible price can reach is refused instead of being answered with a fantasy.

Provenance

Standard seller-side settlement rollup: price less commission, payoff, costs and concessions

Commission taken as a percentage of the sale price and subtracted along with the mortgage payoff, the seller’s closing costs and any concession — with the relation also invertible to solve for the price that produces a required net.

Educational reference, not financial advice, and not a settlement statement. Commission practice, seller-side charges, transfer duties and every tax consequence of a sale differ by place and by circumstance, so nothing here is defaulted from any jurisdiction — the figures are the reader’s own, from their own payoff quote, agreement and estimates. The signed pack carries its own citation, which displays from the verified leaf once the calculator loads; the page reports the verification state of the release it mounted rather than asserting one.
