How Estate Agent Commission Works in South Africa

When you sell a property in South Africa, your estate agent earns a commission — a percentage of the final sale price — payable by the seller at registration. Unlike some countries where a flat fee or tiered structure applies, South African commission is entirely percentage-based and freely negotiable between seller and agent. There is no statutory cap or floor.

The commission is governed by the mandate agreement, which is a legal contract between you and the agency. Under the Property Practitioners Act 22 of 2019, an estate agent cannot claim commission without a valid written mandate. Before you list your property, ensure the mandate clearly states the agreed rate, whether it is inclusive or exclusive of VAT, and the mandate period. Verbal commission agreements are unenforceable.

The typical range you will encounter in the South African market is 5% to 7.5% of the sale price, excluding VAT. A rate of 5% is standard on the open market for well-priced properties in active suburbs. On higher-value properties, or where a sole mandate is offered, agents may accept 4% to 4.5%. On open mandates — where multiple agents can market the property simultaneously — 6% to 7.5% is not uncommon, as each agent carries the risk of doing marketing work without a guaranteed payout. Use our estate agent commission calculator above to model the impact of different rates on your net proceeds before you commit.

VAT on Commission — What You Actually Pay

VAT at 15% is levied on the commission amount for all VAT-registered property practitioners in South Africa. Virtually all licensed estate agents operating at scale are VAT vendors, so it is safe to assume VAT applies unless explicitly confirmed otherwise by your agent.

This means on a R2,000,000 sale at 5% commission, the base commission is R100,000 — but the total you pay is R115,000. The R15,000 difference is VAT that the agency collects on behalf of SARS. It is not a hidden charge or markup; it is simply the tax payable on the service. When comparing agent quotes, always ask whether the stated rate is inclusive or exclusive of VAT — most agents quote exclusive of VAT, which means the real cost is 15% higher than the headline number.

Sole Mandate vs Open Mandate — The Commission Trade-Off

The mandate type you choose has a direct bearing on the commission rate you can negotiate. A sole mandate grants one agency the exclusive right to market and sell your property for an agreed period — typically 60 to 90 days. Because the agent is guaranteed to receive the commission if a sale takes place during that window (regardless of whether they personally introduced the buyer), they carry less financial risk and are generally willing to accept a lower rate.

An open mandate allows any number of agents to market the property simultaneously, with commission paid only to the agent who introduces the successful buyer. Each agent faces the risk that a competitor closes the deal first, making their marketing expenditure a sunk cost. To compensate for this risk, agents on open mandates typically charge higher rates — 6% to 7.5% is common. If speed is your priority and you are confident in the property's marketability, a short sole mandate at a negotiated rate often produces a better financial outcome than an open mandate at a higher rate.

For investors tracking selling costs as part of a full return analysis, pair this tool with our Capital Gains Tax Calculator — agent commission is a deductible selling cost that reduces your taxable capital gain.

How Commission Affects Your Net Proceeds and CGT

Commission is not just a cost — it is a SARS-recognised deductible when calculating your capital gain on disposal. Under the Eighth Schedule to the Income Tax Act, the proceeds from disposal are reduced by the costs of selling, which includes estate agent commission (total amount, inclusive of VAT). This reduces your taxable capital gain, which in turn reduces the CGT you pay.

On a property sold for R2,500,000 with 5% commission, the VAT-inclusive commission of R143,750 is deducted from gross proceeds before calculating the gain. If your base cost (purchase price plus transfer costs paid at acquisition, plus capital improvements) was R1,600,000, your capital gain is R2,500,000 minus R143,750 minus R1,600,000 = R756,250 — not R900,000. At the individual 40% inclusion rate and 36% marginal rate, the difference in CGT on the deductible commission alone is approximately R20,700 in your favour. Always capture commission invoices and mandate documents as part of your disposal records.

Sellers with an outstanding bond should also note that the bond is settled by the conveyancer at registration from the sale proceeds — it is not deducted from the proceeds before CGT is calculated, but it does affect the actual cash you receive. Use the outstanding bond field in the calculator above to model your true cash position after registration.

Negotiating Commission — What Actually Works

Commission negotiation is standard practice in South Africa and agents expect it. The most effective levers are:

• Offer a sole mandate — the most powerful lever. A 60-day sole mandate at 4.5% is almost always cheaper than an open mandate at 6%, and sole mandates typically produce faster sales due to the agent's full commitment.
• Price your property correctly — agents will negotiate lower rates on properties that are priced at market, because a quick sale requires less marketing effort. Overpriced properties are a liability, and agents will price their risk accordingly.
• Compare multiple agents — get mandates from at least three agencies. The market for commission is competitive, especially in active suburbs. Use competing offers as leverage.
• Negotiate a sliding scale — some sellers agree to 4.5% if the property sells within 30 days, rising to 5.5% thereafter. This aligns the agent's incentive with a fast sale.
• Check if your agent is VAT-registered — a non-VAT-registered agent at 5% costs you less than a VAT-registered agent at 5% (R100,000 vs R115,000 on a R2m sale). Uncommon for large agencies, but worth confirming.

Whatever rate you agree, ensure it is captured in writing in the mandate before the property is marketed. Verbal commission agreements cannot be enforced.

Manual Calculation — The Commission Formula

To calculate estate agent commission manually:

Example: Sale price R1,800,000, commission 5.5%, VAT applicable, outstanding bond R650,000.

• Commission excl. VAT: R1,800,000 × 5.5% = R99,000
• VAT: R99,000 × 15% = R14,850
• Total commission: R99,000 + R14,850 = R113,850
• Net proceeds: R1,800,000 − R113,850 − R650,000 = R1,036,150
