The UmweltFlexkonto is UmweltBank's easy-access savings account, offered by a bank that specializes in sustainable and ecological investments. Unlike a fixed-term deposit, this account does not tie up your money for a set period — you can access it at any time. It is aimed at savers who want to park money short-term and flexibly without committing to a fixed term, while supporting a green-focused bank whose lending, according to its own claims, follows ecological and social criteria. As with a typical instant-access savings account, the balance is available daily, with no notice period and no minimum term.
UmweltBank pays 3.00% p.a. on new deposits for the first six months after account opening, but only on the portion of the balance up to €50,000. For any amount above that threshold, a significantly lower rate of 0.75% p.a. applies during the same period, so anyone depositing considerably more than €50,000 should keep in mind that only the first portion earns the high introductory rate. Once the six-month promotional period ends, the then-current UmweltFlexkonto standard rate applies to the entire balance — the offer page does not state a specific figure for this follow-on rate, so savers should check the current rate with the bank before the promotion expires. The rate is variable and is not guaranteed for the full life of the account, meaning it can also be adjusted during the six months in line with the general interest-rate environment.
No minimum deposit is required. Opening the account requires a reference account — the IBAN of an existing checking account, which does not need to be held at UmweltBank. Deposits and withdrawals run exclusively through this reference account, so a separate payment account at UmweltBank is not needed for the UmweltFlexkonto. Deposits are covered by the statutory deposit guarantee scheme up to €100,000 per person and bank, as is standard for all German banks. The offer page does not list any account management fees.
The UmweltFlexkonto is best suited to savers looking for a competitive rate over a manageable six-month window on balances up to €50,000, while also supporting a sustainability-focused bank. Anyone planning to keep money in the account beyond the promotional period should check directly with UmweltBank shortly before the six months are up to see what the follow-on rate actually is, since it is neither guaranteed nor stated in advance.
