You’ve made the transition into working life, but high interest on your student loan is weighing on your new salary? Many graduates pay hundreds of euros too much because they do not adapt the terms of their old loan to their new financial situation. Find out how a strategic refinancing can significantly lower your monthly instalment.
The topic in brief and concise terms
After entering the workforce, a fixed income provides the ideal basis for replacing expensive student loans with variable interest rates with a cheaper instalment loan.
KfW student loans can be refinanced at any time without an early repayment penalty, which makes switching particularly attractive.
Refinancing is often worthwhile with an interest rate difference of just one percentage point and can halve the interest burden.
Identifying potential: When refinancing really pays off
Refinancing is particularly worthwhile when the interest rate on your new loan is significantly lower than that of the old one. A difference of just one percentage point can, with an outstanding balance of €15,000 over ten years, mean savings of more than €800. The key is starting work, because a regular income is the most important prerequisite for banks to offer you top terms. Many graduates with KfW loans are affected by interest rate increases, as their interest rate is variable and adjusts every six months. So check your current contract: if the interest rate is above four per cent, the savings potential from refinancing is high. Fortunately, many student loan providers such as KfW do not charge an early repayment fee, which massively lowers the barrier to switching. This allows you to optimise your financial burden straight after starting working life, instead of paying unnecessarily high interest. Reviewing your current terms is the first step towards reducing your monthly burden through targeted refinancing.
The debt restructuring process: in four steps to lower interest rates
The path to a cheaper loan is more straightforward than is often assumed and can be completed in four clear steps. Careful preparation ensures that you achieve the best possible result and sustainably ease the strain on your finances. Start with a precise review of your current liabilities.
Check the terms: Determine the exact remaining debt, the current interest rate and the remaining term of your student loan. You can find these figures on your latest account statement or in the provider’s online portal.
Compare offers: Obtain non-binding offers for instalment loans from different banks. In doing so, pay attention not only to the effective annual interest rate, but also to the option of making overpayments.
Submit an application: Once you have found the best offer, submit the loan application. You will usually need your last three payslips, your employment contract and a copy of your identity card. A correct household budget calculation for the loan application increases your chances.
Settle the old loan: After approval, the new bank transfers the loan amount either to your account or directly to the previous lender. Inform your previous provider that the loan has been fully settled.
Many graduates overlook the fact that some banks take care of the entire settlement service for them. This structured process ensures that you remain in control and avoid pitfalls.
Typical pitfalls when refinancing and how to avoid them
Although refinancing offers significant advantages, there are three common mistakes that can reduce financial success. The first mistake is focusing only on the monthly instalment. A lower instalment can be bought at the cost of a longer term, which can actually increase the total cost in the end. Always calculate the total cost over the full term. The second pitfall is hidden fees. While an early repayment penalty is rare with student loans, processing fees may apply to new instalment loans and must be included in the effective interest rate. A loan comparison should always be based on the annual percentage rate. The third mistake is negatively affecting your own creditworthiness. Too many credit enquiries with different banks within a short period can lower your SCHUFA score. Instead, use rate enquiries, which are SCHUFA-neutral. If you consolidate several loans, this often even improves clarity and therefore your creditworthiness. A considered approach to these aspects ensures you get the maximum benefit from your refinancing.
Expert tip: Use creditworthiness as the key to securing top terms
Your creditworthiness, also known as your credit rating, is the key factor for the interest terms in a refinancing arrangement. Banks assess the risk of a loan default, and a permanent employment contract with a regular net income of over €2,000 significantly reduces this risk. A good SCHUFA score is the foundation. Request a free data copy at least once a year so that incorrect entries can be corrected. Even a single negative entry can make refinancing several percentage points more expensive. Our expert tip: carry out a household budget calculation before submitting your refinancing application. List all income and expenses in detail. A clear monthly surplus of at least €500 after all costs signals financial stability to the bank. This can strengthen your negotiating position and pave the way for an improvement in your credit rating. That way, you secure not just any rate, but the best possible interest rate for your financial future.
Special case KfW loan: use flexibility and avoid interest traps
The KfW student loan is the most widely used student loan in Germany and has a number of special features. Its interest rate is variable and is adjusted to the capital market twice a year, on 1 April and 1 October. In the recent past, this led to an increase in interest rates to over eight per cent. The good news, however, is that the KfW loan can be repaid in full or in part at any time without additional costs. This flexibility is a tremendous advantage when refinancing. You do not have to fear any early repayment fee, which can amount to up to one per cent of the remaining debt with other instalment loans. Use this clause specifically as soon as you receive a cheaper loan offer with a fixed interest rate. Switching from a variable KfW interest rate of eight per cent to a fixed instalment loan rate of four per cent immediately halves your interest burden. This is a crucial step in freeing yourself from unpredictable interest rate fluctuations and securing a financially predictable future, for example through a loan for professional development.

FAQ
What documents do I need for refinancing?
As a rule, you will need your last three payslips, your employment contract, a copy of your identity card, the settlement statement for your current loan with the exact outstanding balance, as well as an overview of your monthly expenses.
How long does a debt restructuring take?
From the application to the disbursement and settlement of the existing loan, the process typically takes between one and three weeks, depending on the processing times of the banks involved.
Does debt restructuring improve my SCHUFA score?
If you consolidate several loans into a single one, this can have a positive effect on your SCHUFA score, as it improves the clarity of your finances. A single credit enquiry has a small, usually neutral, short-term effect.
What is the difference between a terms enquiry and a credit enquiry?
A conditions enquiry is SCHUFA-neutral and serves solely to compare offers. By contrast, a formal credit enquiry is recorded in your SCHUFA file for one year and, if made too frequently, can slightly lower the score.
Can I also use the new loan for other purposes?
Yes, if you take out an instalment loan for unrestricted use that is higher than the remaining balance of the student loan, you can use the excess amount for other purposes. However, this should be carefully considered so as not to increase the debt burden unnecessarily.
Is refinancing worthwhile even with a small remaining debt?
Even with a smaller outstanding balance of under 5,000 euros, refinancing can be worthwhile if the interest rate difference is large enough. The effort involved is relatively low and can still lead to noticeable financial relief.
