What is the OTTO base fee?
Last updated: 31 October 2026 · The MargenOptimierer app is in German. Button and menu names are shown exactly as you see them, with the English meaning in brackets.
The OTTO base fee is the fixed amount OTTO charges you every month for your seller account, on top of the other OTTO fees.
It doesn't belong to any single item. MargenOptimierer therefore only deducts it from the contribution margin of the whole account, in the „Ohne Artikel“ (without item) row. Only the part that falls within your chosen period counts.
Example: OTTO base fee in September
Say OTTO charges an OTTO base fee of 99.90 € a month. If you look at the margin for all of September, MargenOptimierer subtracts that 99.90 € from the account's contribution margin.
What else matters with the OTTO base fee
Not the base price of MargenOptimierer
You pay the OTTO base fee to OTTO. What you pay MargenOptimierer is called the base price. It appears on your MargenOptimierer invoice, not in the margin.
On the Marge (margin) page
On the Marge page, the line is called OTTO-Grundgebühr (OTTO base fee) and appears only in the margin of the whole account.
Where the amount comes from
MargenOptimierer stores the amount, and you don't enter anything. MargenOptimierer deducts a separate OTTO base fee for each OTTO account.
