Real Estate Commission Calculator — see who actually gets paid what

A real estate commission calculator exists because almost nobody — buyers, sellers, or first-year agents — can do this math in their head once a deal has a negotiated split, a brokerage cut, and a listing side and buyer side that no longer have to match. Punch in your sale price and terms above and you'll see, dollar for dollar, where the commission actually goes before you sign anything.

We built this tool because the rules changed in 2026 in a way that catches a lot of sellers off guard, and Arb Digital gets asked about it constantly by clients buying and selling homes while working with us on their next move. This page walks through what changed, how the math works, and where people still get surprised at the closing table.

What This Real Estate Commission Calculator Does

You give it four numbers: the sale price, the total commission percentage, how that total is split between the listing side and the buyer side, and the percentage your individual agent keeps after their brokerage takes its cut. The calculator returns the total dollar amount paid in commission, the listing-side dollar amount, the buyer-side dollar amount, what your specific agent walks away with after the brokerage split, and — most importantly — the net proceeds a seller keeps once commission is subtracted from the sale price. It's a real estate commission calculator built for the post-2024 landscape, where none of these percentages are fixed or assumed.

How to Use It

1. Enter the sale price. Use the actual accepted offer price, not the list price, since commission is calculated on the final contract amount in almost every listing agreement.
2. Set the total commission percentage. This is whatever you negotiated with your listing agent — commonly somewhere between 4% and 6%, but there is no legal standard and it is fully negotiable.
3. Set the listing-side split. This is the percentage of the total commission that goes to the listing brokerage versus what, if anything, the seller has agreed to offer toward buyer-agent compensation.
4. Enter your agent's broker split. Individual agents rarely keep 100% of their side's commission — most operate on a split with their brokerage, commonly 50/50 up to 90/10 for high-producing agents.
5. Read the results. The big number is total commission paid on the transaction; the grid below breaks it into the four numbers that actually matter to you.

The Formula Behind the Numbers

The math itself is simple multiplication, but the order matters. Total commission equals the sale price multiplied by the total commission percentage. That total is then divided according to the listing-side split you enter — for example, a 50/50 split on a 5.5% total commission means 2.75% goes toward the listing side and 2.75% goes toward whatever buyer-side compensation was negotiated. From there, your individual agent's take is calculated by applying the broker-split percentage to their side of the commission, since the brokerage keeps a cut before the agent ever sees a check. Net proceeds to the seller is simply the sale price minus the total commission dollar amount — this calculator does not account for mortgage payoff, closing costs, or repairs, which is why we built a dedicated home sale proceeds calculator for that fuller picture. For background on how commissions are structured and disclosed, the Consumer Financial Protection Bureau publishes plain-language guidance on closing costs and how agent compensation fits into a real estate transaction.

What the 2024 NAR Settlement Actually Changed

For decades, the standard practice was straightforward on the surface: the seller paid a total commission, typically 5–6%, and that amount was pre-set and shown in the MLS, split between the listing brokerage and whichever brokerage brought the buyer. Sellers rarely negotiated the buyer-side number because it was baked into how the whole system worked, and buyers almost never discussed compensation with their own agent because it felt like someone else's problem.

The National Association of Realtors settled a set of antitrust lawsuits in 2024 over exactly this practice, and the rule changes that followed reshaped how commissions are presented and negotiated. Two changes matter most for anyone using a real estate commission calculator today. First, offers of buyer-broker compensation can no longer be published in the MLS — that number is now negotiated directly and disclosed outside the listing itself, which means it varies far more from one sale to another than it used to. Second, buyers working with an agent are now required to sign a written buyer-representation agreement up front that spells out how much their agent will be paid and by whom, before touring homes. That agreement can specify a flat fee, an hourly rate, or a percentage — and it does not have to be paid by the seller at all.

The practical result is that the "buyer side" input in this calculator is no longer a number you can assume. Some sellers still offer to cover buyer-agent compensation as a concession to attract offers, especially in slower markets, because buyers who have to pay their own agent out of pocket are a smaller pool. Other sellers offer nothing and let buyers negotiate that cost separately, sometimes rolling it into the purchase price or asking for a seller credit at closing. Sellers should treat the buyer-side percentage as a strategic decision, not a formality — set it too low in a competitive market and some buyer agents may steer clients elsewhere; set it generously and you may be leaving money on the table if buyer demand is already strong.

Why the Total Percentage Is Genuinely Negotiable

Commission percentages were never legally fixed, but the old system made a de facto standard feel unavoidable. That pressure has eased. Sellers with homes that show well, sit in a hot micro-market, or come with a strong pricing strategy have real leverage to negotiate the listing-side fee down, especially with agents who do high volume and can afford lower per-transaction margins. On the other end, unique or hard-to-sell properties, complex transactions, or markets with slow absorption may command commission at or above the historical average because the agent is taking on more marketing cost and risk.

It helps to separate "total commission" from "value delivered." A lower percentage on a home that sits unsold for six months while carrying costs pile up isn't actually a discount — it can cost more than a slightly higher commission paid to an agent who prices, stages, and markets the property correctly and sells it in three weeks. Use this calculator to model a few scenarios — 4%, 5%, 6% — against your specific sale price so you can see the real dollar spread before you negotiate, rather than negotiating against an abstract percentage.

Where Agents Actually See the Money

A commission percentage isn't take-home pay for the person who helped you buy or sell. Most agents operate under a brokerage and give up a meaningful share of their commission in exchange for the brand, leads, office support, transaction coordination, and E&O insurance the brokerage provides. New agents commonly start on splits as low as 50/50, while experienced, high-producing agents can negotiate 80/20, 90/10, or flat-fee "cap" arrangements where they keep nearly everything past a certain annual threshold. On top of the broker split, many agents also pay a per-transaction fee, franchise fee, or MLS and association dues out of their share, so the number this calculator shows as "agent's take" is still gross, not fully net of business expenses.

This is worth knowing if you're negotiating commission directly with an agent rather than a brokerage policy — an agent on a weak split has less room to discount their fee than one who keeps 90% of what they bring in, and understanding that dynamic can make the negotiation more productive for both sides.

Common Mistakes to Avoid

• Assuming a 50/50 split is standard. Since the settlement, the listing/buyer split is whatever was negotiated in your specific listing agreement — never assume it mirrors a neighbor's deal or a number you saw online.
• Forgetting the buyer-side fee might not be seller-paid at all. Buyers should confirm in their buyer-representation agreement exactly who pays their agent before assuming the seller is covering it.
• Confusing gross commission with an agent's actual pay. The brokerage split and any per-transaction fees mean an agent's real take-home is almost always lower than the "buyer side" or "listing side" total.
• Comparing commission percentage alone across agents. A slightly higher fee paired with a proven pricing and marketing strategy often nets a seller more money than a discount agent who prices too high or too low.
• Not modeling the net proceeds separately. Commission is only one deduction from a sale price — mortgage payoff, closing costs, and repair credits also come out before you see a wire.
