Allegro or your ownshop in 2026?Let's do the maths.
A sales commission looks harmless until you multiply it by a year. We put the real cost of selling on a marketplace next to the cost of running your own shop, and show where it stops adding up.
Allegro sellers rarely add the commission up month by month; they treat it as the natural cost of being on the platform. That holds until revenue grows: the commission scales with your sales, and a shop subscription doesn't.
Your own shop doesn't mean “instead”
The most common mistake here is framing it as either-or. The sellers who come out ahead stay on the marketplace for the traffic and add their own shop for the margin and the customer data. There's one condition: both routes have to draw down the same warehouse, or the first oversell costs more than the whole exercise earned.

When it stops adding up
The threshold is easy to work out: your own shop starts earning the moment the monthly commission exceeds the subscription plus the cost of the traffic you have to bring in yourself. With regular customers and products bought on a cycle, that moment arrives earlier than most sellers assume.
The second thing the table doesn't show: on a marketplace you have no customer list. You can't send an email, run remarketing or suggest a follow-up purchase. Every sale starts from zero.
If the table tells you the commission costs less than buying your own traffic, stay where you are. If it says the opposite, run the numbers again with returning customers included. They move the result more than anything else.
