Your account is in the red – the overdraft makes it possible, but often costs 9–11% interest per year. If you don't clear the negative balance quickly, you pay far more than necessary. We compare the classic overdraft (Dispokredit) with cheaper revolving credit lines (Rahmenkredit) and show when refinancing is worthwhile.
Note: the interest rates shown are taken from the providers' websites (as of October 2026), are variable and partly depend on your credit rating. The provider's current terms are what counts.
Overdraft or revolving credit – which is cheaper?
An arranged overdraft (Dispo) is convenient because it is tied to your current account – but it is expensive: overdraft rates are often 9–11% p. a. (e.g. DKB 9.06–9.66%, norisbank 11.00%, as of October 2026). If you stay overdrawn permanently, you lose out. A revolving credit line (Rahmenkredit or Abrufkredit) works similarly: you get a fixed credit limit and only pay interest on the amount you actually use. But it is not automatically much cheaper – ING's revolving credit currently costs 8.54% APR. An instalment loan is usually much cheaper if your credit score is good: starting rates in the current comparison begin at around 2%, and the representative (two-thirds) rates mostly range from about 3% to 9%.
Rule of thumb: for bridging a short gap, the overdraft is fine. If the negative balance becomes permanent, a revolving credit line or a classic instalment loan for refinancing is worthwhile.
Unarranged overdraft – the expensive trap
If you go beyond your arranged overdraft limit, or overdraw without an arranged overdraft, this is known as an unarranged (tolerated) overdraft. Many banks charge a higher rate for it than for the arranged overdraft; some do not (at norisbank, for example, both are 11.00%). Banks must state the exact rate in their price list and on their website. You should end this situation as quickly as possible, for example by refinancing with a low-cost instalment loan.
Your rights: advice obligation and new rules from 20 Nov 2026
If you use your overdraft continuously for six months and on average for more than 75% of the limit, your bank must offer you advice on cheaper alternatives (Section 504a German Civil Code, BGB). For an unarranged overdraft this applies after three months if it averages more than half of your monthly incoming payments (Section 505(2) BGB).
With the implementation of the EU Consumer Credit Directive (EU) 2023/2225 – the Bundestag passed the law on 17 April 2026 and it applies from 20 November 2026 – stricter information and protection duties apply to overdrafts, including a right of withdrawal. Creditworthiness checks are also tightened overall.
How overdraft interest is calculated
With an overdraft facility you pay interest only for the days and the amount your account is in the red. The debit interest rate is a fixed or variable annual rate applied to the respective balance on a daily basis. The bank usually credits the interest to your account at the end of a quarter or month, so it appears as a charge on the statement. If this pushes your account further into the red, interest is then charged on the interest as well.
A worked example using sample values (not the current terms of any specific provider): at a debit rate of 10% p.a. and an average overdraft of €1,500 over three months, interest is about €37.50 (€1,500 × 10% × 3/12). If the same overdraft stays in place for a whole year, that is around €150. An instalment loan of €1,500 at a sample rate of 6% over twelve months, by contrast, costs just over €49 in interest, because you pay the debt down every month.
The difference arises not only from the rate but from repayment. An overdraft has no fixed repayment, so the debt often stays unchanged for months. A loan with fixed instalments forces you to reduce the debt visibly. If you regularly go into the red, look up the overdraft interest you have paid each year on your statement or annual summary.
When refinancing pays off
An instalment loan for refinancing is worthwhile if your account has been in the red for several months in a row and you have no prospect of clearing it soon. You take out a loan for the amount of the overdraft, clear the account and repay the loan in fixed instalments. What matters is the comparison of the effective annual interest rate, as it combines all the costs of the loan. The bank must state it in the pre-contractual information before the contract is concluded.
Be careful with payment protection insurance, which some banks offer in addition. It noticeably raises the total cost and is not compulsory. Under section 500(2) of the German Civil Code (BGB) you may repay the loan early, in whole or in part, at any time. The bank may demand only an early repayment fee, which under section 502 BGB is capped at 1% of the amount repaid early, or 0.5% if the remaining term is twelve months or less.
Refinancing makes sense only if you do not max out the overdraft again afterwards. A household budget that sets fixed expenses against income helps. Consumer advice centres and debt counselling services support you with this, often free of charge or for a small fee.
Cancelling, reducing or blocking the overdraft
The bank is not obliged to grant you an overdraft. Under the statutory rules on consumer loans it can terminate it with two months' notice, or without notice for good cause (section 500(1) BGB, section 314 BGB). Such a termination mainly occurs when your income situation worsens markedly or payments are missed. You can cancel the overdraft yourself at any time or reduce the limit.
If you are reluctant to use the overdraft, you can ask the bank to lower it or remove it entirely. This protects against overdrawing unintentionally and has no disadvantages for your creditworthiness. With a garnishment-protected account (P-Konto, section 850k of the German Code of Civil Procedure) an overdraft is excluded anyway, because only credit balances are protected.
If an account is persistently debited beyond the overdraft despite insufficient funds, the bank may refuse payments, return direct debits and charge reminder costs. Returned-debit fees are listed in the price and service list. With several returned direct debits, Schufa entries (Schufa is Germany's main credit reference agency) and follow-up costs from creditors are also a risk.
Alternatives when money runs short
Before you exhaust the overdraft, check whether you can postpone expenses or speed up income. For rent arrears, energy debts or insurance premiums, talking to the creditor about paying in instalments is worthwhile, as payment arrangements are often cheaper than overdraft interest. Some municipalities offer help in special emergencies, and local social advice services can tell you about entitlements.
A small cushion in a savings account is the best prevention. Two to three months' expenses are often enough to absorb late pay or unexpected bills. If you have no room for that, at least set up a standing order of €20 to €50 a month so that the reserve grows.
If that is not enough, non-profit debt counselling services run by municipalities, welfare associations and consumer advice centres can help. They help you gain an overview, approach creditors and, if necessary, show ways out of over-indebtedness. Do not wait until reminders arrive.
