Realtor Commission Calculator — Payments, Cost & Breakdown
I’m David McAllister. This tool estimates the total real estate commission on a US home sale and splits it between seller’s and buyer’s agents. Quick, clean numbers you can plug into your net proceeds plan.
Quick Start
- Enter home sale price (USD).
- Enter total commission rate (% of sale price).
- Set the seller vs. buyer agent shares so they sum to 100%.
- Calculate to see total commission and each agent’s portion.
How It Works
- Inputs → sale price, total commission rate, split between agents.
- Outputs → total commission dollars, seller agent commission, buyer agent commission.
- Assumes a straight percentage on the final sale price, then splits by your sliders.
Formula / Method
Compact equations, aligned with the calculator:
- total_commission = sale_price × (commission_rate / 100)
- seller_agent_commission = total_commission × (seller_agent_share / 100)
- buyer_agent_commission = total_commission × (buyer_agent_share / 100)
Variables:
- sale_price: home sale price in USD.
- commission_rate: total commission percent of sale price.
- seller_agent_share: share of total commission to the listing agent (%).
- buyer_agent_share: share of total commission to the buyer’s agent (%).
Worked Example
Example with local US formatting:
- Sale price: $450,000
- Total commission rate: 6%
- Seller agent share: 50%
- Buyer agent share: 50%
Stepwise:
- Total commission = $450,000 × 6% = $27,000
- Seller agent = $27,000 × 50% = $13,500
- Buyer agent = $27,000 × 50% = $13,500
Applications / Use Cases
- Listing prep: estimate commission before signing a listing agreement.
- Offer planning: test how price changes affect commission in dollars.
- Net proceeds: plug the output into your closing worksheet alongside taxes, title, and payoff.
Tips / Common Mistakes
- Watch the split: seller and buyer shares must total 100%.
- Rate vs. dollars: small rate changes on big prices move the dollars a lot—check sensitivity.
- Round-tripping: if concessions reduce the sale price, commission drops accordingly.
Risk/Note: Fees, broker splits with individual agents, referral fees, or MLS/admin charges are not included here. This tool only covers gross commission paid from the transaction.
