The Landlord's Kitchen in Your Frankfurt Apartment Comes With a Real, Calculable Rent Surcharge
When a Frankfurt landlord offers an apartment with a fitted kitchen already included, that convenience typically comes with a real, calculable monthly rent surcharge, not a free amenity, and this math is the same nationwide, it isn't set by anything specific to Frankfurt's own Mietspiegel. The standard formula: take the kitchen's purchase price, divide it by its estimated useful life, add in interest on that capital, then divide by 12 for a monthly figure, an 8,500-euro kitchen with a 20-year useful life at 5 percent interest works out to roughly 70.83 euros a month, 850 euros a year, added to your Kaltmiete. In practice, market-typical surcharges also get expressed as 0.7 to 1.0 euro per square meter added to the Kaltmiete, or the kitchen's presence simply justifies placing the unit in a higher rent-comparison category. Frankfurt's own qualified Mietspiegel, last updated in 2024 with an average Kaltmiete around 12.50 to 13.05 euros per square meter for new leases, is exactly the kind of local comparison document a fitted-kitchen surcharge often gets folded into, rather than itemized as a separate line. The kitchen is depreciated on a straight-line basis over 10 years regardless of whether individual appliances get replaced along the way, and courts have accepted a useful-life range as wide as 10 to 25 years in different rulings. The genuine advantage of taking the landlord's kitchen and its surcharge: your landlord, not you, stays responsible for its repairs and maintenance, and you skip both the upfront cost and the hassle of installing then later dismantling or reselling your own.
The Official Rule
Moving into a Frankfurt apartment that already comes with a fitted kitchen feels like a convenience, and often it is, but it’s worth understanding upfront that this convenience typically comes with a genuine, calculable cost baked into your rent, rather than being a free extra from the landlord.
A landlord-provided kitchen usually carries a real monthly surcharge, calculated with a standard, widely used formula. Take the kitchen’s purchase price, divide it by its estimated useful life, add in interest on that capital, then divide by 12 to get a monthly figure. Applied to an 8,500-euro kitchen with a 20-year useful life at 5 percent interest, that works out to roughly 70.83 euros a month, about 850 euros a year, added on top of your Kaltmiete.
| Element | Detail |
|---|---|
| Formula | Purchase price ÷ useful life + capital interest, divided by 12 |
| Worked example | 8,500 euro kitchen, 20-year life, 5% interest ≈ 70.83 euros/month |
| Market-typical alternative | 0.7 to 1.0 euro per square meter added to the Kaltmiete |
| Standard depreciation period | 10 years, straight-line, regardless of individual appliance replacements |
| Court-accepted useful-life range | As wide as 10 to 25 years in different rulings |
In practice, this surcharge often isn’t itemized as its own line, it gets folded into where your unit lands on the local rent comparison. Frankfurt’s own qualified Mietspiegel, last updated in 2024, puts the city’s average Kaltmiete at roughly 12.50 euros per square meter overall, and around 13.05 euros per square meter for new or renewed leases specifically. A fitted kitchen is exactly the kind of feature, alongside things like a balcony or a renovated bathroom, that can justify placing an apartment higher within that local comparison range, rather than showing up as a separate surcharge on your lease.
The depreciation schedule stays consistent regardless of what happens to individual appliances over time. A kitchen is generally depreciated on a straight-line basis over 10 years, even if a stove or refrigerator within it gets replaced along the way, and courts have accepted a considerably wider range, from 10 up to 25 years, as a reasonable useful-life assumption depending on the specific case.
The formula and depreciation rules themselves are nationwide, not Frankfurt-specific, it’s only the local rent baseline that changes city to city. The underlying math comes from BGB principles and court rulings that apply the same way whether you’re renting in Frankfurt, Munich, or elsewhere in Germany. What genuinely varies by city is the local Mietspiegel that a kitchen surcharge gets measured against, and Frankfurt’s own document is the reference point for judging whether a specific surcharge looks reasonable here.

What Real People Say
Newcomers apartment-hunting in Frankfurt describe being surprised to learn that a listed apartment with an Einbauküche isn’t simply cheaper to skip, several mention realizing only after signing that the kitchen’s cost was effectively already baked into the Kaltmiete rather than appearing as its own line.
Tenants who negotiated directly with a landlord over a fitted kitchen describe asking specifically how the surcharge was calculated, purchase price, assumed useful life, and interest rate, several found landlords willing to share this breakdown once asked, which made it easier to judge whether the added cost was actually reasonable.
Step by Step
- Ask directly whether the listed Kaltmiete already reflects the kitchen, or whether there’s a separate surcharge line.
- If there’s a surcharge, ask for the underlying numbers, purchase price, assumed useful life, and interest rate, so you can check the math yourself.
- Compare the resulting per-square-meter rent against Frankfurt’s own Mietspiegel range, to judge whether the total feels reasonable for the location and condition.
- Weigh the surcharge against the cost and hassle of installing your own kitchen, including eventual removal or resale when you move out.
- Remember the landlord stays responsible for repairs, if you keep their kitchen, this is a genuine practical benefit that doesn’t show up in the monthly math itself.
Compliance Note
This page explains the general nationwide framework and formula for landlord-kitchen rent surcharges in Germany, current as of mid-2026, alongside Frankfurt’s own local Mietspiegel context. It is not legal or financial advice, and specific surcharge amounts can vary by landlord and lease. Confirm your own lease terms directly with your landlord or a tenant association.
FAQ & Common Pitfalls
Is a landlord-fitted kitchen actually free if it's already in the apartment when I move in?
Generally not in practice. Even when a fitted kitchen isn't itemized as a separate line on your lease, its cost is typically already folded into the Kaltmiete, either through a direct surcharge calculation or by placing the unit in a higher category on the local Mietspiegel. It's rarely a true freebie.
How is the surcharge actually calculated?
The standard formula takes the kitchen's purchase price, divides it by its estimated useful life, adds interest on that capital, and divides the result by 12 for a monthly figure. An 8,500-euro kitchen with a 20-year useful life at 5 percent interest works out to roughly 70.83 euros a month, about 850 euros a year.
Does Frankfurt's own Mietspiegel set a different surcharge formula than other German cities?
No, the surcharge formula itself, and the underlying depreciation and useful-life rules, come from BGB principles and nationwide court rulings, not from Frankfurt's Mietspiegel specifically. What Frankfurt's Mietspiegel does provide is the local baseline Kaltmiete, currently around 12.50 to 13.05 euros per square meter for new leases, that a kitchen's presence can push into a higher comparison category.
Is it worth negotiating to keep the landlord's kitchen instead of installing our own?
Often yes, even accounting for the surcharge. Beyond skipping the upfront cost of buying a full kitchen, the landlord stays responsible for repairs and maintenance of their own fitted kitchen, and you avoid the hassle of eventually dismantling, storing, or reselling a kitchen you installed yourself when you move out.
