How Alberta commission usually works
The most quoted structure in Alberta applies a higher percentage to the first $100,000 of the price and a lower percentage to everything above it. A typical example is 7% on the first $100,000 and 3% on the balance. That total is the combined commission for both brokerages — the listing side and the buyer side — and 5% GST is added on top.
Why the rate is only a starting point
Nothing about commission is fixed. Some brokerages offer flat fees, some discount the listing side, and full-service brokerages bundle in photography, marketing, and negotiation that cheaper options skip. The right question is not just the rate but the net result: what the home sells for, minus the commission, compared with what a different approach would net you. That is the number that actually lands in your bank account.
Frequently asked questions
How much is real estate commission in Alberta?+
A common Alberta model is 7% on the first $100,000 of the sale price and 3% on the balance, plus 5% GST. On a $450,000 home that works out to about $17,500 in commission plus $875 GST, or roughly $18,375 in total. Commission is always negotiable, so your rate may differ.
Who pays the realtor commission?+
The seller pays the total commission out of the sale proceeds at closing, and it is split between the listing brokerage and the buyer's brokerage. Buyers do not normally pay commission directly, though that can be part of the negotiation.
Is commission negotiable?+
Yes. There is no fixed or legally mandated commission rate in Alberta or anywhere in Canada. Rates and structures vary by brokerage and by the services included, which is exactly why this calculator lets you adjust the rates.
Do I pay GST on the commission?+
Yes. A real estate commission is a service, so 5% GST applies on top of the commission amount. The calculator includes it by default; you can toggle it off to see the pre-tax figure.
How is the commission split between agents?+
The total commission is typically divided between the listing side and the buyer side, often close to a 50/50 split, and each brokerage then shares with its agent. The calculator shows the per-side amount so you can see how the total is allocated.
