The iad fee scale is based on a tiered system applied to the sale price of the property, but a raw reading of this scale is not enough to understand what the buyer or seller actually pays. Several modulation mechanisms, rarely documented in mainstream articles, alter the final amount of the commission.
iad Fee Scale by Price Tiers: Calculation Mechanics and Local Adjustments
The iad network applies a national fee scale structured by price tiers, published and updated periodically. The principle is decreasing: as the sale price increases, the commission rate decreases in percentage. This structure resembles that of most networks of agents, but iad adds a layer of granularity by property type (apartment, house, land) in certain segments.

What competing articles omit: this national scale is supplemented by adjustments decided at the level of regional group heads. In tight markets or for certain specific segments, discounts, caps, or flat fees may be offered. An iad advisor in Île-de-France does not necessarily charge the same rate as an advisor in a rural area, even for a property with the same price.
We observe that this regional flexibility creates a sometimes significant gap between the scale displayed online and the amount actually negotiated. Before signing a mandate, it is relevant to understand how the iad agency fees for a sale break down on the relevant price segment by requesting a detailed simulation from the local advisor.

Seller Charge or Buyer Charge: Tax Impact on the iad Calculation Base
The mention “fees borne by the seller” or “fees borne by the buyer” is not just a matter of presentation. It directly modifies the tax base of the transaction, and thus the amount of transfer taxes (commonly referred to as “notary fees”).
When the fees are borne by the buyer, the transfer taxes are calculated on the price excluding commission. The savings for the buyer can represent several hundred euros on a property of average value. When they are borne by the seller, the displayed price includes the commission, and the transfer taxes are based on the total amount.
At iad, some advisors systematically offer two “net seller” simulations on the same mandate, one with buyer charge and the other with seller charge. This practice allows the seller to visualize the real impact on their net price, and the buyer to measure the total cost of the transaction. It is a negotiation lever that we recommend explicitly requesting, as it is not always offered spontaneously.
- With buyer charge: the price displayed in the ad is the net seller price, to which the fees are added. The transfer taxes apply only to the net price.
- With seller charge: the displayed price includes the commission. The transfer taxes are calculated on this total amount, which increases the cost for the buyer.
- The choice between the two formulas falls under the mandate signed between the seller and the iad advisor and can be discussed before signing.
iad Fees and Properties Classified F or G: The DPE Variable
Since the gradual tightening of rental bans related to the Climate and Resilience law, properties classified F or G in the energy performance diagnosis have suffered a depreciation in the market. This reality also affects the commission of agents.
At iad, as in other networks, advisors increasingly incorporate a “DPE argument” into the negotiation of fees on energy-hungry properties. The logic is simple: an energy-intensive property sells for less and more slowly. To facilitate the transaction, the commission is sometimes revised downwards, either by the advisor themselves or at the request of the local group head.
This trend is not formalized in the official scale. It results from a pragmatic adaptation on the ground. For a seller whose property is classified F or G, the margin for negotiating fees is therefore wider than for a properly classified property.
Exclusive iad Mandate and Its Effect on Actual Commission
The type of mandate influences the rate actually applied. An exclusive mandate entrusted to an iad advisor guarantees them to be the sole intermediary, which reduces their commercial risk. In return, the commission can be negotiated down compared to the standard scale applicable in a simple mandate.
This mechanism is not unique to iad, but it takes on a particular dimension in a network of independent agents. The iad advisor directly bears their costs (no commercial premises, no physical storefront), which gives them pricing flexibility that a salaried agent of a traditional agency does not have. The exclusive mandate remains the main negotiation lever for fees in this model.
In practice, we recommend comparing not the displayed rate, but the amount in euros of the commission relative to the net seller price. A slightly higher rate on an exclusive mandate, coupled with better marketing support (professional photos, multi-portal distribution, home staging), can generate a higher final sale price, and thus a better net result for the seller.
Display Obligation and Verification Before Signing the Mandate
Regulations require all real estate professionals, including iad agents, to clearly display their fees. This scale must appear on every ad, with a mention of the party bearing the costs.
- Check that the scale displayed in the ad corresponds to the rate proposed in the mandate.
- Request a written breakdown of the calculation: net seller price, amount of the commission in euros, applied rate, party bearing the fees.
- Compare this amount with the buyer charge and seller charge simulations to identify the most tax-advantageous formula.
A discrepancy between the national iad scale and the proposal from the local advisor is not unusual, but it must be justified and formalized in the mandate. Any commission that is not explicitly stated in the signed mandate is legally unenforceable.
