This calculator vs. Zillow's Home Sale Calculator
Zillow's Home Sale Calculator is a free, well-known estimator that starts from a Zestimate and one blended commission line, to give a rough sense of proceeds before you have an offer. This page starts from an offer you actually have, splits buyer-broker compensation out as its own negotiated line, and compares two offers side by side — with nothing sent to a server.
What each one is for
Zillow's Home Sale Calculator is a free estimator on Zillow's own site. Per Zillow's own description, it begins from your home's Zestimate — Zillow's automated valuation estimate — or a price you enter, then walks through typical selling costs (agent commission, closing costs, mortgage payoff, home-prep and repair costs) to estimate what a sale would net. It is a reasonable place to start before you have listed a house or received an offer, and it lives inside Zillow's real estate marketplace, where a saved estimate can be tied to a Zillow account and a Zestimate for the property.
This page starts one step later: after a listing agreement exists and an offer is on the table. It takes the actual sale price on that offer (or two competing offers) and the actual rates from your listing agreement and closing estimate — not a typical range — and turns them into cash to the seller.
One modelling difference is worth stating plainly, because it is the reason this tool's number can disagree with a blended-commission estimate. Zillow's own published guidance describes agent commission as sellers typically paying both their own agent and the buyer's agent, each around 2-3% of the sale price — a combined commission figure. After the NAR settlement, buyer-broker compensation is a separately negotiated seller concession, not an automatic split of one blended rate, and it can differ between two offers on the same house. This page keeps listing-broker pay and buyer-broker compensation on two independent lines for exactly that reason.
| Question | Where to answer it |
|---|---|
| What might my house net, roughly, before I have listed it or received an offer? | Zillow's Home Sale Calculator — it is built to estimate from a Zestimate or a hypothetical price. |
| What does this specific offer actually net, using my real listing-agreement rate and closing estimate? | This calculator — every figure is one you enter from your own paperwork, not a typical range. |
| Which of two offers in front of me right now leaves more cash? | This calculator's offer comparison — both offers side by side on the same assumptions. |
| Does a higher offer asking for more buyer-broker pay or concessions still net more? | This calculator — buyer-broker compensation and concessions are their own lines, which is where a bigger offer can quietly become a smaller one. |
| What sale price do I need to walk away with a specific number? | This calculator's target-net solver, which inverts the same arithmetic. |
| Do I need an account, or is a value tied to a Zillow listing profile? | This calculator: no account, no address lookup, nothing sent anywhere. Zillow's tool runs on Zillow's own real estate marketplace site. |
The two answer different moments rather than competing for the same one: Zillow's calculator for a rough estimate before a listing or an offer exists, this page for the decision between real offers once they do. This calculator is arithmetic, not a closing disclosure or a valuation, and it is not a substitute for a title company, escrow officer, attorney, or tax adviser.
This tool needs no account and no sign-in: it is a static page, the arithmetic runs in your browser, and once it has loaded it keeps working with the connection off.
Common questions
Should I use this calculator or Zillow's Home Sale Calculator?
Different starting points, and both are useful. Zillow's Home Sale Calculator is a free tool on Zillow's own site that begins from a Zestimate — Zillow's automated estimate of what a home is worth — and walks through typical selling costs to estimate proceeds before you have an offer in hand. This page starts from a real number: the price on an offer you actually received (or two, side by side), and turns it into cash at closing using the rates from your own listing agreement and closing estimate rather than typical ranges. Use Zillow's tool to get a rough sense of what a sale might net before you list; use this one once offers exist and you are deciding between them.
Does Zillow's calculator split buyer-broker compensation the way this page does?
Zillow's own published guidance on the calculator describes agent commission as a combined figure — sellers typically paying both their listing agent and the buyer's agent, at roughly 2-3% of the sale price each — presented as one commission line rather than as a separately negotiated seller concession. This page treats listing-broker pay and buyer-broker compensation as two distinct, independently entered lines on purpose: after the NAR settlement, buyer-broker compensation is a negotiated amount that can differ between two offers on the same house, and a single blended commission rate cannot show that difference. That difference is exactly what decides which of two offers actually nets more.
Does Zillow's calculator compare two offers side by side?
Zillow's calculator is built around one scenario at a time, refined by editing the sale price and costs for a single estimate. This page's offer comparison holds the loan payoff and closing-cost assumptions constant and puts two full offers next to each other, so the number that changes is the one that actually differs between them — useful in the hours before responding to a counter, not just for a general estimate.
Does anything I type here leave my browser?
No. This calculator runs entirely on your own device: there is no account, no address lookup, and nothing you enter is sent anywhere. Zillow's calculator runs on Zillow's own site, which is a real estate marketplace and lead-generation business — reasonable for what it is, and worth knowing if you would rather not have a sale estimate tied to an account or a listing profile.
Is this page affiliated with Zillow?
No. This site is not affiliated with, endorsed by, or sponsored by Zillow. Zillow is a trademark of Zillow, Inc., named here only to describe what this calculator is and is not, based on Zillow's own public description of its Home Sale Calculator.
