Fee structure comparison
Flat fee vs percentage: which is better?
A head-to-head analysis with a crossover chart, price-point examples, and a decision guide, so you can work out which structure costs less at your price.
Compare Agent FeesTwo structures. Very different outcomes.
Buyers agents charge either a fixed flat fee or a percentage of the purchase price (REBAA). Which costs less depends on how much you are spending.
A flat fee stays the same whatever you pay; a percentage grows with the price. Divide a flat quote by a percentage quote and you have the price where the two cost the same. This page works one example through: a $15,000 flat quote against 2%, the low end of the industry body REBAA's national average of 2% to 3% plus GST.

The crossover chart
Purchase price on the horizontal axis, fee cost on the vertical. The teal line is the example flat quote of $15,000. The grey diagonal is a 2% fee. They cross at $750,000; above that price the flat quote costs less.

Head-to-head: six dimensions
Beyond price, the two structures differ on cost certainty, incentive alignment, and budget planning.
| Flat Fee | Percentage Fee | |
|---|---|---|
| Cost certainty | High. Exact cost agreed before search starts. | Lower. Final cost unknown until settlement. |
| Agent incentive alignment | Agent earns the same regardless of what you pay. | Structural misalignment: agent earns more if you pay more. |
| Budget planning | Easy. One known line item in your purchase budget. | Harder. Total fee is a moving target. |
| Best for | Prices above the crossover, where a percentage is a large dollar amount. | Prices below the crossover, where a percentage can cost less than a flat quote. |
| Published figure | None. Ask two or three agents for a written quote. | 2% to 3% plus GST, the national average (REBAA). |
| Hidden cost risk | Low (fee cannot increase after signing). | Higher. If purchase price rises, so does the fee. |

Which fits your purchase?
Match your situation to a structure. The dollar figures use the example quotes above: $15,000 flat against 2%.
| Flat Fee | Percentage Fee | |
|---|---|---|
| Budget under $600K | Costs more than 2% here, compare first | 2% of $500K is $10K, less than flat |
| Budget $600K – $900K | Equal at $750K | Equal at $750K |
| Budget $1M – $1.5M | $5K less at $1M, $15K less at $1.5M | 2% of $1M is $20K |
| Budget above $1.5M | $25K less at $2M | 2% of $2M is $40K |
| Want complete cost certainty | Locked in from day one | Fee moves with purchase price |
| Buying interstate or remotely | Cost known from the start | If agent only offers % structure |
| Building investment portfolio | Agent earns the same whatever you pay | Incentive misalignment compounds |

When flat fee wins
Your price is above the crossover
Divide the flat quote by the percentage to find it. On a $15,000 flat quote against 2%, every dollar you pay above $750,000 adds to the percentage fee and not to the flat one.
You need budget certainty
Flat fees let you factor the agent cost into your total purchase budget on day one. No moving parts.
Agent incentive matters to you
A flat-fee agent earns the same regardless of what you pay for the property, perfectly aligned with your goal.
Prestige or complex markets
At prestige prices a percentage becomes a large dollar amount, so ask every agent for a flat quote as well.
Investment portfolio buying
The difference repeats with every purchase. On the example quotes, each $1.2M purchase costs $9,000 less on the flat quote than at 2%, so five cost $45,000 less.
Percentage fee pitfalls
Fee grows if you stretch your budget
If your ceiling is $900K but you end up at $1.1M, a 2% fee is $18K at your ceiling and $22K at the price you paid. The agent earns more the more you spend.
Total cost is unknown at signing
You cannot lock the percentage fee into your budget. It is a variable that resolves only at settlement, weeks or months later.
Structural incentive misalignment
Even if your agent is ethical, the percentage model creates a theoretical financial benefit from higher purchase prices.
GST amplifies the impact
A 2% fee on a $1.2M property is $24,000 plus GST, or $26,400 all up. The percentage compounds with the GST multiplier.
Harder to compare quotes
Two agents charging "2%" are not directly comparable if one includes more services or has a different percentage base.
