What an office really costs
Team size15 desks
The real cost of an office

A traditional lease isn’t one cost.
It’s a stack of them.

Rent is where it starts — not where it ends. Drag to your team size and see what running your own office really adds up to — and what flex saves you.

01 · The monthly bill

Nine bills, or one.

Run a 15-desk office yourself and rent is just the first of nine line items every month. Flex folds all of them into a single subscription.

02 · The footprint

Rent less. Use more.

Build your own and every room — meeting, kitchen, breakout — sits inside your lease, paid for and half-empty most of the week. In flex, the big rooms are shared, so your private space shrinks while what you can use multiplies.

You rent the purple box. You use everything around it — no sqm, no fit-out.

90 sqmless private space to rent, heat, clean and furnish — yet a bigger, better office to walk into.
≈ €2,862/mo you never pay · ≈ €108,000 of fit-out you never build
The big rooms are shared — so this is part of why a flex desk costs less, not a discount on top.

Assumes ≈13 m²/desk for a self-built office (your own meeting rooms + kitchen) vs ≈7 m²/desk private in flex with shared amenities — about 45% less space to rent. An estimate; adjust to your own plan.

03 · Day one

One signature vs. a project plan.

Same 15 desks. The difference is everything that stands between today and your team’s first working Monday.

04 · How long will you stay?

The lease isn’t always the loser.

Set the amenities aside for a moment. On money alone, a long lease can win — its big upfront cost spreads over the years. The catch: it only works if your team stays put and stays the same size.

Even across 10 years, flex stays cheaper — the fit-out never earns itself back at these rates.

flex still wins at this horizon

Assumes a lease run lean at €380/desk/mo (no shared amenities) plus €16k/desk fit-out, vs. flex at €480/desk all-in. Team change modelled at ±15%/yr.

The bottom line

Same team. A bigger office. €3,685/mo lighter.

For a 15-desk team, flex isn’t just cheaper on paper — it removes the capex, the months, and the long lease entirely.
