House Sale Calculator: What You Actually Walk Away With

What a House Sale Calculator Actually Calculates

A house sale calculator starts with one input, your expected sale price, and works backward through every deduction that stands between that number and what actually lands in your bank account. The core formula is simple: sale price, minus mortgage payoff, minus agent commission, minus closing costs, minus any repair credits or buyer concessions, equals net proceeds.

The sale price is the easy part to guess. The deductions are where most sellers underestimate how much comes off the top.

The Deductions That Shrink Your Number

Agent commission is usually the single biggest deduction, historically running 5-6% of the sale price split between the listing agent and buyer's agent, though the exact structure now gets negotiated deal by deal following a 2024 industry settlement that changed how buyer-agent compensation is offered. On top of that, sellers typically pay their own closing costs separate from commission, commonly cited in the 1-3% range for items like title insurance, transfer taxes, and prorated property taxes or HOA dues.

Then there's the mortgage payoff, which isn't just your remaining balance, it usually includes a per-day interest accrual up to the closing date. And if a buyer's inspection turns up problems, sellers often end up crediting money back at closing to keep the deal together, a cost that's nearly impossible to predict before an inspector walks through.

Why the Calculator's Number Is Still an Estimate

Even a well-built calculator can't know what a buyer's inspector will find, whether financing will fall through and restart the clock, or what a final walk-through will turn up. Every input you feed it, commission rate, closing cost percentage, repair budget, is itself an estimate until you're actually under contract.

That's why the number from a calculator is useful for planning and dangerous for promising. It tells you roughly what to expect. It doesn't lock anything.

A Calculator That Skips Most of the Deductions

Cash Flow Deals gives you two offers to compare against your calculator results: the Fast Cash Offer, where we buy your house as-is and close, and the Premium Cash Offer, where a pre-approved FHA or conventional buyer we already have, ready to go, pays more and buys directly from you. You choose.

We cover repair costs, and we figure out a way, so nothing comes out of your pocket. With Premium, only what the buyer's lender requires gets fixed, with repair costs settled from the sale proceeds out of our share. With Fast Cash, we buy as-is, so you have no repairs to make.

The number is agreed before any work starts, and it changes only if you agree. The one exception: if something structural surfaces that was not visible or disclosed before we signed — foundation issues, hidden moisture, old wiring, cast-iron drain failure — we re-cost it and bring the number back to you. You decide. You can walk away. We disclose what we know at offer time so this almost never happens.

If the buyer's loan falls through, that is our problem, not yours, and you can still take the Fast Cash Offer at its own number alongside the Premium Cash Offer you considered.

Run your calculator first, then compare what you would actually receive with each offer. On Premium, costs are settled from the sale proceeds out of our share, not deducted from your agreed number; the structural exception above applies.
