NZ real estate commission calculator

Compare published fee structures at one expected sale price, include GST and fixed charges, then inspect exactly how each estimate was produced.

Decision principle

Compare the complete written proposal — commission, GST, administration, marketing, services and local evidence.

Your estimate

Enter an expected sale price

Every result uses the same price. Published structures appear only when the complete formula is source-backed.

Official source

Actual commission can be negotiated and may vary by agent, office, property, location and agreement. Confirm GST, minimums, marketing and administration charges in writing. Two published structures do not represent the whole market.

Barfoot & Thompson is excluded from this national comparison until the calculator can enforce its Auckland/Northland and property-type rules. Office-variable and incomplete structures remain excluded.

What this calculator includes

Each result shows commission before and after GST, effective commission percentage, estimated proceeds after commission and a visible formula. A custom mode lets you model a tiered quote without submitting personal information.

What it does not prove

A lower calculated fee is not evidence that an agency or agent will produce a better net result. Campaign quality, buyer reach, negotiation, property fit and every additional charge still matter.

Why only two agencies?

PropertySeller only calculates structures it can apply without guessing an office, location or property-type rule. Barfoot & Thompson has a source-backed structure, but it remains outside this national comparison until those eligibility rules can be enforced.

Understand the quote before comparing it

The NZ agent fees and commission guide explains tiers, minimums, administration fees, GST, marketing exclusions and the questions to resolve before signing an agency agreement.
