Taking Out a Loan: What You Need to Know

Understand interest rates, compare offers, avoid pitfalls: the complete guide to taking out a loan in Germany. Includes an amortization calculator.

Reading time: 10 min.

A loan can open up opportunities – whether for a car, further education, or your first apartment. But a poorly chosen loan can also lead you straight into debt. This guide explains what to watch out for before you sign.

Key takeaways

  • Compare the effective interest rate (Effektivzins) – not the nominal rate or the monthly payment
  • Keep all loan installments to a maximum of 35-40% of your net income
  • Use a soft rate quote (Konditionsanfrage, SCHUFA-neutral) instead of a formal loan application
  • Payment protection insurance is usually unnecessary and overpriced

Types of Loans at a Glance

Not all loans are the same. Depending on what you need the money for, there are different products with different terms.

Installment Loan (Ratenkredit)

The classic option for purchases: you borrow a fixed amount (€1,000-75,000) and repay it in monthly installments. Typical term: 12-84 months. Advantage: fixed payment, fixed interest rate, predictable costs.

Car Loan (Autokredit)

A special installment loan for vehicles. Often cheaper because the car serves as collateral. Variant: balloon financing with a low monthly payment and a high final payment.

Mortgage Financing (Baufinanzierung)

For buying or building a home. Large amounts (€100,000-500,000+), long terms (15-30 years), a land charge (Grundschuld) as collateral. Significantly more complex than an installment loan.

Overdraft (Dispokredit)

Overdrawing your checking account. Maximum flexibility, but extremely expensive (10-15% interest). Only for short-term shortfalls, never as permanent financing!

Credit Line (Rahmenkredit)

A credit line like the overdraft, but cheaper (5-8%). You only pay interest on the amount you actually use. Good for fluctuating capital needs.

Understanding Interest Rates and APR

Interest is the price you pay for borrowed money. But which rate is the right one to compare?

Nominal Rate vs. Effective Rate

  • Sollzins (nominal interest rate): The pure interest rate on the loan amount. Doesn't include any additional costs.
  • Effektivzins (effective interest rate/APR): Includes all costs of the loan, expressed as an annual rate. This is the number to compare!

What's Included in the Effektivzins?

  • Sollzins (nominal rate)
  • Processing fees
  • Account management fees
  • Interest calculation method (monthly, annually)
  • Not included: payment protection insurance, fees for a separate loan account

Fixed-Rate Periods for Mortgages

With mortgage financing, the interest rate is fixed for a set period (5, 10, 15, 20 years). After that, it's renegotiated – and the rate can go up or down.

Requirements for Getting a Loan

Banks don't grant a loan to just anyone. You need to meet certain criteria.

Basic Requirements

  • Legal age (18+)
  • Residence in Germany
  • A German bank account
  • Regular income
  • No negative SCHUFA entries

What the Bank Checks

  • Income: permanent employment, self-employment, pension. Fixed-term contracts make it harder.
  • Expenses: rent, existing loans, maintenance payments.
  • SCHUFA score: the higher, the better. Ideally: >97%.
  • Collateral: for real estate: a land charge (Grundschuld). For cars: the vehicle title.

Improving Your Creditworthiness

  • Cancel unnecessary credit cards
  • Close old, unused accounts
  • Pay off existing loans on time
  • Check your SCHUFA report (free once a year)

Reading Your Amortization Schedule

The amortization schedule shows you how your loan develops over its term. It's your roadmap to becoming debt-free.

The Components

  • Remaining balance (Restschuld): how much you still owe
  • Payment: your monthly amount (usually stays the same)
  • Interest portion: what goes to the bank (decreases over time)
  • Principal portion: what reduces your debt (increases over time)

Why the Interest Portion Decreases

You pay interest on your remaining balance. The more you've repaid, the lower the remaining balance, and the less interest you pay. With an amortizing loan (Annuitätendarlehen), the payment stays constant, but the principal portion grows.

Example: €10,000 Loan, 5% Interest, 3 Years

  • Monthly payment: approx. €300
  • First payment: €42 interest, €258 principal
  • Last payment: €1 interest, €299 principal
  • Total interest paid: approx. €790

Comparing Loans Correctly

Comparing loans can save you hundreds or thousands of euros. But make sure you compare correctly!

Step by Step

  1. Determine how much you need: How much do you really need? Don't borrow more than necessary.
  2. Set the term: A shorter term means higher payments, but less interest overall.
  3. Use comparison portals: Check24, Smava, and Verivox show you many providers at a glance.
  4. Compare the Effektivzins: Not the Sollzins, not the monthly payment – the effective rate!
  5. Submit rate quote requests: "Window" advertised rates often only apply to top creditworthiness. Get real offers.

Important: Rate Quote Request vs. Loan Application

  • Konditionsanfrage (rate quote request): SCHUFA-neutral, for comparison only. You can submit as many as you like.
  • Kreditanfrage (loan application): gets recorded in your SCHUFA file. Several within a short time = a worse score.

Make sure comparison portals only submit rate quote requests, not full loan applications!

Extra Repayments: Yes or No?

Extra repayments (Sondertilgungen) are unscheduled payments that reduce your remaining balance faster. But are they always worth it?

Advantages of Extra Repayments

  • Debt-free sooner
  • Less interest overall
  • Psychologically liberating

When Extra Repayments Are Worth It

  • With high loan interest rates (>5%)
  • If you don't have a better investment option anyway
  • With long-term loans (mortgages)

When They're Usually Not

  • With low interest rates (<3%): investing often pays off more
  • If it would eat into your emergency fund
  • If an early repayment penalty (Vorfälligkeitsentschädigung) applies

Rule of Thumb

Loan interest rate > expected after-tax investment return → make extra repayments. Loan interest rate < investment return → invest instead.

Avoiding Common Loan Pitfalls

Pitfall 1: Payment Protection Insurance

Banks like to sell payment protection insurance (Restschuldversicherung, RSV) along with the loan. It's often overpriced and full of exclusions. Decline it, or check alternatives (existing disability cover, term life insurance).

Watch Out for Payment Protection Insurance

Payment protection insurance can cost up to 20% of the loan amount and often comes with strict exclusion clauses. Germany's consumer advice centers (Verbraucherzentrale) advise against it in most cases.

Pitfall 2: 0% Financing

Sounds great, but is often expensive: the retailer raises the purchase price or offers no discount. Compare: what does the product cost if you pay cash and negotiate, versus paying in installments?

Pitfall 3: Balloon Financing Without a Plan

Low monthly payments, a high final payment – tempting. But: will you have the money for the final payment, or will you need to take out another loan then?

Pitfall 4: Overdraft as Permanent Debt

If you're permanently in the red, you pay 10-15% interest. An installment loan to refinance your overdraft can cut that interest roughly in half.

Pitfall 5: Too Many Loan Applications

Every real loan application gets recorded in your SCHUFA file. Several within a short time signal financial trouble = a worse score. Use rate quote requests instead!

Alternatives to a Bank Loan

Family and Friends

Often interest-free or cheap. But: always put it in writing! Verbal agreements lead to conflict. Clear repayment terms are a must.

Employer Loans

Some employers offer low-interest loans. Tax-advantaged up to certain limits. Downside: it ties you to the employer.

KfW Subsidized Loans

For certain purposes (studies, starting a business, energy-efficient renovation), there are low-interest government loans available through KfW, Germany's state development bank.

P2P Loans

Platforms like Auxmoney connect you with loans from private individuals. Often available even with weaker creditworthiness, but more expensive than bank loans.

Saving Instead of Borrowing

The best alternative: don't take out a loan at all. For consumer purchases, it's better to save up. The psychological effect is different – and you don't pay any interest.

Frequently Asked Questions About Taking Out a Loan

Frequently Asked Questions

The rule of thumb: a maximum of 35-40% of your net income for all loan payments combined (including rent). At €3,000 net, that would be €1,050-1,200. Many banks calculate more conservatively, using 30%. Work it out yourself: what's really left over after rent, insurance, and living expenses?

The Sollzins is the pure interest rate on the loan amount. The Effektivzins includes all costs: processing fees, account management, credit insurance. Always use the Effektivzins to compare offers! It shows the true cost per year.

Yes, significantly. With a very good score (97%+), you'll get the advertised top rates. With a medium score (80-95%), the rate can be 2-3 percentage points higher. With a poor score (<80%), you often won't get a loan at all, or only at extortionate rates.

Yes, for installment loans taken out since 2010, with a maximum early repayment penalty of 1% (0.5% if the remaining term is under 12 months). For mortgages, it's more complicated: after 10 years, you can cancel free of charge with 6 months' notice. Before that, only with an early repayment penalty, which can get expensive.

Refinancing is worth it when the new interest rate is significantly lower than the old one and the savings exceed the costs (early repayment penalty, processing fees). Rule of thumb: run the numbers if the interest rate difference is more than 2% and the remaining term is over 2 years.
