The direct answer
Listing-side and buyer-side compensation are separate transaction assumptions tied to their applicable agreements and payment responsibilities. The numerical split can be modeled, but it is not determined by a universal rule or necessarily paid by one party.
Separate representation from the payment amount
Identify the services and representation arrangement for each side before assigning a fee. A payment source does not by itself explain every agency relationship or contractual obligation. The guide concerns the compensation arithmetic; it does not interpret representation agreements. Review the governing documents for who owes each amount and what conditions apply.

Reconcile total and side amounts explicitly
The commission calculator permits a total rate and two independent side rates. For a consistent two-side scenario, check whether the side amounts sum to the intended total. A difference may reflect separate assumptions or an error; the tool does not conceal it by forcing a residual amount. Flat-fee mode follows the same principle with dollar entries.
Distinguish transaction compensation from retained earnings
A side amount can be reduced by referrals, brokerage splits and other charges before an individual receives a net amount. The seller’s cash-proceeds model may also need a different allocation depending on the agreement. Keep each layer separate and avoid calling the whole side amount agent take-home income. No rate or division in the examples is an industry requirement.
Worked example
On $500,000 price, a 2% listing-side assumption gives $10,000 and a 3% buyer-side assumption gives $15,000. They sum to $25,000. If the separately entered total rate is 4%, its $20,000 result differs from that sum and needs reconciliation rather than silent adjustment.

Common mistakes and limitations
Do not assume a 50/50 division or that all compensation automatically reduces seller proceeds. Use the agreed responsibility and each calculation base.
Broker compensation is negotiable and not set by law. The calculator must not describe any percentage as standard or required.
Frequently asked questions
Must both side rates be equal?
No. Enter the applicable scenario; no equal-division rule is built into the calculator.
Why does the tool allow a total that differs from the sides?
The inputs are independent assumptions. Showing all amounts helps identify a mismatch rather than hiding it.
