Who really pays the platform fee?

Last updated: July 2026

You quote $2,400 on a marketplace. The platform takes 10%. A month later, $2,160 arrives in your account, and somewhere in your accounting, $240 has quietly changed owners.

In short: to pass a marketplace fee to the client, divide your price by one minus the fee (a 20% fee means dividing by 0.8), because adding 20% on top still leaves you short. The free Project Price Calculator grosses up correctly.

Who paid that fee? Whoever set the price without thinking about it. Usually you.

The math most freelancers get wrong

The intuitive fix is to add the fee on top: 10% fee, so quote 10% more. It feels right, but it's wrong.

Add 10% to $2,400 and you get $2,640. The platform takes its 10% of that number, not of your old one: $2,640 minus $264 leaves $2,376. Still short. You chased the fee and it moved.

The correct move is a gross-up (adding the fee to the total): divide by one minus the fee. $2,400 ÷ 0.9 = $2,667. The platform takes $267, you keep your $2,400, and the fee has landed where it belongs, on the client's side of the invoice.

Adding is not enough

Adding 10% to a $2,400 quote gives $2,640, and 10% off that leaves $2,376: still short. Dividing by 0.9 gives $2,667 invoiced and exactly $2,400 kept.

Of every $100 the client pays, $83 pays for the work itself and $17 shields you from scope creep. If the client pushes the price down, the buffer slice is what thins first; the work slice is your floor.

Try adjusting the fee percentage. The platform slice grows, the invoice total climbs, and your labor slice stays whole. That last part is the entire point: the calculator adds the fee automatically, so the platform cost is never paid by you.

Is the fee worth it at all?

Judge it like what it is: a customer acquisition cost.

A platform that takes 15% is charging you 15% to fill your pipeline. Compare that with what filling it yourself costs: prospecting hours, portfolio upkeep, proposals that go nowhere. Early on, when your own pipeline is thin, 15% for a steady stream of clients can be a fair trade.

Now consider the other side: it also costs money and time to the client to find the right person for the job. There is a reason why successful recruiting companies make so much money. So you could argue that it would be fair to share the fee 50/50 between you and the client. Keep that in mind and use it as a negotiation tool.

The platform's cut is a marketing budget. Judge it like one.

The double haircut

One mistake deserves its own warning: covering the fee yourself AND giving a discount on the same project. A 10% discount on a quote that was never increased to cover a 10% fee leaves you working for roughly 80% of your intended price, simply because each cut felt small enough to let slide.

Cuts stack. Make sure every price drop is visible: add the fee first, then adjust the scope. Treat every discount like the real negotiation it is.
