Ask what retail space in Germany costs and the market reports give you a number: 340 euros per square metre and month in Munich, 250 euros in Hamburg, 280 in Berlin and Frankfurt – the prime rents reported by the major brokerage houses for the second quarter of 2026. Yet hardly any lease is economically performed at that price. Between the figure in the report and what actually flows over a ten-year term sit rent-free periods, fit-out contributions and stepped rents. The number that makes this difference visible is the effective rent – and it appears in no published report.
Key takeaways
- Prime rents in market reports are headline rents: the contractual rent before any incentives.
- Rent-free periods, fit-out contributions and stepped rents noticeably reduce the real cost – by around 8 to 10 percent in our model calculation, and often more in individual cases.
- The formula is simple: all rents paid minus one-off landlord contributions, divided by months and square metres.
- Landlords use incentives deliberately to protect the headline rent – it underpins the property valuation and serves as the benchmark for the location.
- Tenants should never compare competing offers on the quoted rate per square metre, but only on an effective-rent basis.
Why the published prime rent is never the price
The published prime rent is a useful benchmark – it describes what is nominally agreed for an idealised unit of 60 to 120 square metres in the very best pitch. That is precisely its limitation: it is a contractual value, not a payment value. What the landlord contributes to the fit-out, how many months the tenant pays no rent during the works, and how the rent steps up in the early years is captured by no published statistic. These terms are negotiated, treated as confidential between the parties – and economically they often make the difference between two seemingly identical offers.
For both sides of the table the conclusion is the same: whoever negotiates only the rate per square metre is negotiating the wrong number. What matters is what actually flows over the term.
The three big incentives
Rent-free period
The classic incentive: the tenant pays no rent, or a reduced rent, in the opening months. Economically the rent-free period first covers the fit-out phase, in which the unit generates no turnover – though what is negotiated frequently exceeds the pure construction time. For the landlord it is a calculable concession: the headline rent remains untouched, the waiver is limited in time and applies only once, at the start of the lease.
Fit-out contribution
With a fit-out contribution – the German market term is Baukostenzuschuss, or BKZ – the landlord makes a one-off payment towards the tenant’s works, from the basic store build to technical upgrades of the unit. For the tenant it lowers the initial investment, which for flagship formats quickly reaches seven figures. One thing matters for a clean calculation: a contribution only helps to the extent that it covers genuine, unavoidable fit-out costs. A large subsidy for a unit that needs heavy works can be worth less economically than a smaller one for a unit in good condition.
Stepped rents
Under a stepped rent the lease starts at a reduced level that rises in agreed increments to the target rent. It smooths the ramp-up phase, in which a new store still has to build its turnover. Unlike rent-free time and contributions, the step works over several years – and it is the incentive most often overlooked when comparing offers, because the lease prominently shows the end value.
The model calculation: 250 euros becomes 226
How strongly these instruments work is best shown with a deliberately simple model. The figures are assumptions for illustration – not market averages, because published averages for incentives do not exist:
- Unit: 200 m² in a German prime high-street location
- Headline rent: €250 per m² and month, i.e. €50,000 per month
- Term: 10 years (120 months) – nominal rental volume: €6.0 million
- Agreed: 6 months rent-free for fit-out and ramp-up, plus a €150,000 fit-out contribution
The arithmetic: instead of €6.0 million the tenant pays €5.7 million (114 rather than 120 monthly rents); after deducting the contribution, €5.55 million of economic cost remains. Spread over 120 months and 200 square metres, that is an effective rent of roughly €231 per m² – about 7.5 percent below the contractual rent.
Add a ramp-up step – say €230 per m² in the first two years and €240 in the third, before the €250 target applies – and the effective rent falls by roughly another €5 to around €226 per m², a good 9.5 percent below the headline figure. Both parties can publicly work with 250 euros; what is paid is a different number.
The formula fits in one line: effective rent = (sum of all rents paid − one-off landlord contributions) ÷ term in months ÷ square metres. Institutional investors additionally discount the cash flows to present value – for comparing offers in practice, the undiscounted view is almost always enough.
The practical test: when the pricier offer is the cheaper one
A second example shows what effective rent means for comparing offers. An expansion team is weighing two comparable units in the same pitch. Offer A quotes €240 per m² – expressly marketed as the cheaper option – but grants neither rent-free time nor a contribution. Offer B carries €250 per m² in the lease, yet comes with the terms from our model: six months rent-free and a €150,000 fit-out contribution. On paper, A is ten euros ahead. Calculated effectively, the picture flips: B costs roughly €231 per m² over the term, A an unchanged €240. The nominally more expensive offer is economically nine euros per square metre and month cheaper – on 200 square metres a difference of more than €21,000 a year and over €210,000 across the term.
Such situations are not a constructed edge case but everyday negotiation reality: because owners defend their headline rents for good reasons, the real price difference between two units is almost never found in the quoted rate – but in the terms behind it.
Why landlords prefer contributing over discounting
At first glance it looks contradictory: why would an owner pay a €150,000 contribution and waive six monthly rents rather than simply lower the rent? The answer lies in how retail property is valued. The asset value derives from the contractual rent – simplified: annual headline rent times a multiplier. In our model, a rent permanently reduced by €19 per m² would cut the annual income by a good €45,000; at a multiplier of 20 that translates into a value effect of more than €900,000. One-off incentives totalling €450,000 are clearly the cheaper solution for the owner – absorbed within a few years, whereas a reduced contractual rent accompanies the entire term and every refinancing.
Then there is the benchmark effect: the headline rent of one deal becomes the reference for every subsequent negotiation in the location – for neighbouring units, for re-lettings, for the street’s next rent tone. A visible discount therefore acts far beyond the individual lease. Incentives deliver the same economic concession without moving that anchor. How owners structure terms intelligently when a unit falls vacant is covered in our piece on re-letting retail space.
What tenants should take from this
For expansion managers the calculation implies a clear sequence. First: before any price negotiation, establish the condition of the unit and the true fit-out costs – only then can you judge what a contribution is actually worth. Second: compare competing locations exclusively on an effective-rent basis and include your own fit-out investment over the term; total occupancy cost per square metre is the only figure that makes two offers comparable. Third: negotiate the structure, not just the rate. A headline rent the landlord must defend for valuation reasons is not a lost negotiating point – it is the lever that wins rent-free time, contributions and steps. How these questions fit into a systematic market-entry process is described in our guide to a retail expansion strategy for Germany.
The special case: turnover rent
The calculation shifts once more when turnover components come into play: a minimum rent plus a percentage share of store sales. Effective rent then depends not only on the agreed terms but on the performance of the location itself – with its own questions around percentages, turnover definitions and reporting. That is material for a separate article in this series.
Conclusion: two numbers, two jobs
Headline rent and effective rent are not competing truths but two numbers with different jobs. The headline rent carries the property valuation and the benchmark of the location; the effective rent describes what was actually agreed economically. Negotiating professionally means knowing both numbers, keeping them cleanly apart – and knowing which of the two is on the table at any given point of the negotiation. Across Germany’s prime retail locations that is truer in 2026 than ever: published prime rents barely move – the negotiation happens in the terms behind them.
Frequently asked questions about effective rent
What is effective rent?
Effective rent is the true average rental cost of a retail unit over the full lease term – after deducting all incentives such as rent-free periods, fit-out contributions or stepped rents. It regularly sits below the headline rent stated in the lease.
How is effective rent calculated?
Add up all rents actually paid over the term, deduct one-off landlord contributions such as a fit-out subsidy, and divide the result by the number of months and the floor area. Institutional investors additionally discount the cash flows to present value; for comparing offers in a negotiation, the undiscounted calculation is usually sufficient.
How much rent-free time is common in German retail leases?
There is no fixed market standard – the rent-free period is a negotiated outcome and depends on location, condition of the unit, lease term and the tenant’s covenant. The range runs from a few weeks covering the fit-out phase to several months on long leases or units requiring heavy works. In sought-after prime locations the room for negotiation is smaller than in locations with vacancy.
What is a fit-out contribution?
A fit-out contribution (in Germany: Baukostenzuschuss, BKZ) is a one-off payment from the landlord towards the tenant’s fit-out costs. It reduces the tenant’s initial investment without changing the headline rent stated in the lease – which makes it one of the most important tools landlords use to protect the stated rental value of their property.
