Office rent: what an office really costs in 2026

A realistic cost comparison beyond rent and square metres.

Why office costs are almost always miscalculated

Most office decisions do not fail because of the rent. They fail because of what never appears in the cost comparison.

Blind spot 01

Costs reduced to rent

Many comparisons equate the rent with the total cost. Yet gross rent is only one part. Operation, maintenance and adjustments are often left out.

A low price per square metre says little about the real cost burden.

Blind spot 02

Your time is never priced in

Office decisions tie up internal resources permanently. Search, fit-out, coordination and operation take up management, IT and administration.

That time rarely shows up in calculations, yet it directly affects focus.

Blind spot 03

Costs arrive with a delay

Many relevant costs do not arise at move-in but spread across the term. Retrofits, conversions and space changes are missing from the initial calculation.

Looking only at the start means clearly underestimating the total cost.

The calculation

What a classic office really costs per month in 2026

The calculation below shows the real running costs under standard market conditions. Same location, same team, two models.

Flex office€11,800

One amount, predictable every month

The result surprises most people: both models cost almost the same per month. The difference is not the price but the effort, the risk and the commitment – and the question of who takes care of operation, technology and breakdowns.

Two logics

Owning or using: two cost logics compared

Economically, a classic office resembles buying a car, while a flex office resembles a leasing or subscription model.

The ownership model

Classic office

High capital outlay up frontFit-out, technology and furnishing tie up liquidity immediately.
Running costs are deceptiveRepairs, maintenance and adjustments arrive irregularly on top.
Full responsibility for everythingOperation, organisation and problems sit entirely with the user.
Lost time when things breakOutages mean coordination, organisation and internal effort.
Hard to correctTerms and investments can hardly be adjusted flexibly.

Like buying a car: committed once, responsible for good.

The usage model

Flex office

Low start-up effortLittle capital tied up, a fast start, clear terms.
Fixed, predictable monthly costsOperation, technology and service are included.
Risks outsourcedMaintenance, outages and operation sit with the provider.
Time saved day to dayFocus stays on the core business instead of organisation.
Adaptable when things changeGrowth or downsizing are part of the model.

Like leasing: a predictable rate, responsibility with the provider.

The experience factor

Why experience is decisive in office decisions

Office decisions look comparable at first glance. In practice they differ in the detail, and that is exactly where the biggest mistakes happen.

Spotting patterns early

Many problems follow recurring patterns: space that becomes too small faster than planned, or contracts that promise flexibility and never deliver it.

Placing the differences

Offers can be compared, markets cannot. Between operators, concepts and contract logics there are differences that only show up in daily use.

Judging for the long run

A good office decision does not only work at move-in. It has to hold up across the whole term through growth, change or correction.

FAQ

Frequently asked questions about office costs in 2026

The key questions about the cost of your office, answered clearly and directly.

What does an office for 20 employees cost per month?

In Berlin the real total cost of a classic office of around 300 sqm is roughly 11,180 to 12,750 euros per month. A comparable flex office with 20 workstations costs about 11,800 euros, but that includes service charges, electricity, internet, furniture, cleaning and maintenance.

Which office costs are most often forgotten?

Mainly operation and upkeep: maintenance and inspections, insurance, equipment leasing, office supplies and the depreciation of furniture. On top of that comes internal time for search, fit-out and organisation, which appears in hardly any calculation.

Is a flex office more expensive than your own office?

Usually not. Once every item is counted, both models sit close together per month. The difference is structural: with a flex office the amount is predictable and operation is outsourced, while a classic office has nine separate items that fluctuate.

Why is the price per square metre a poor benchmark?

Because it only reflects the base rent. In the example the base rent accounts for only about three quarters of the monthly total. The rest comes from operation, technology and adjustments, some of it years after move-in.
