True Cost of Real Estate Commission Calculator
A 5–6% commission sounds modest on a home price, but it comes out of your equity — which can make it 15–30% of what you actually own. Enter the sale price, commission rate, mortgage balance, and how long you owned the home to see the real numbers.

How does this calculator work?
Net proceeds = sale price − commission − mortgage − other closing costs. Commission as % of equity = commission ÷ (price − mortgage) — often 3–5× the nominal rate. Break-even appreciation = total closing costs ÷ (price − costs). Rates editable; typical US commission is 5–6% of sale price (2025).
Formula
How this is calculated
Real estate commissions are quoted as a percentage of the sale price, typically 4–6% in the United States (split between the buyer's and seller's agents). On a $400,000 home at 5%, that is $20,000 — but if the seller only has $80,000 in equity, the commission represents 25% of what they actually own, not 5%.
This calculator computes: (1) the raw commission and total closing costs subtracted from the sale price, (2) the net proceeds the seller takes home after paying off the mortgage, (3) the commission expressed as a percentage of seller equity to reveal the true burden, (4) the annual cost of the commission spread over the holding period, and (5) the minimum home appreciation percentage needed just to break even on commission and closing costs — the amount the home had to grow in value to make the sale worthwhile.
All figures are estimates. Commission rates, closing costs, and mortgage payoffs vary widely by location, lender, and negotiation. The break-even appreciation percentage ignores tax benefits, investment opportunity cost, and the value of housing services over the holding period — for a comprehensive analysis consult a financial adviser.
Frequently asked questions
Leverage. Most owners finance part of the purchase, so their equity (sale price minus remaining mortgage) is only a fraction of the sale price. A 5% commission on a $500k home is $25k, but if you only have $100k in equity, the commission consumes 25% of your equity — five times higher than the headline rate.
Yes. Commissions are always negotiable. In the US the DOJ/NAR settlement in 2024 changed how buyer-agent commissions are disclosed and paid, increasing transparency and creating more room to negotiate total rates. Flat-fee brokers, discount agents, and FSBO (for-sale-by-owner) are alternatives that reduce total commission costs.
Common seller closing costs beyond commission include transfer or deed taxes, title insurance (where the seller pays), escrow/attorney fees, recording fees, HOA transfer fees, home warranty, and repair credits or concessions agreed with the buyer. Totals vary but often add 1–3% of the sale price on top of commission.
