FAQ
Frequently Asked Questions
What is the difference between a Darlehen and a Kredit?
Legally a Darlehen (§ 488 BGB) is an amount that must be repaid. In everyday use Darlehen and Kredit are synonymous. "Darlehen" sounds more formal and is often used for property and business financing.
What is a bullet loan?
With a bullet (interest-only) loan the borrower pays only interest. The full loan amount is repaid in one sum at the end of the term. Often combined with life insurance or an investment vehicle.
How do I calculate the monthly loan payment?
Annuity formula: payment = loan × (monthly rate × (1+monthly rate)^n) / ((1+monthly rate)^n − 1). Monthly rate = annual rate / 12; n = months. Our calculator does this automatically.
Can I repay a loan early?
Instalment loans (general consumer loans) can be repaid in full or in part at any time (§ 500(2) BGB). The early repayment compensation is at most 1 % of the amount repaid early, or 0.5 % if less than one year remains, and never more than the interest that would have accrued until the agreed end of the term (§ 502(3) BGB). Fixed-rate property loans can be terminated without compensation 10 years after disbursement with six months' notice (§ 489(1) no. 2 BGB); before that only with a legitimate interest, e.g. a sale, against compensation with no statutory cap.

What is the Loan Conditions Calculator?
The loan conditions calculator computes terms for annuity loans, straight-line (constant-principal) loans and bullet (interest-only) loans – showing monthly payment, total interest and term.
How does the Loan Conditions Calculator work?
Under "Calculate installment" choose the loan type and enter amount, rate and term; "Calculate term" and "Calculate amount" assume an annuity loan. Annuity: constant payment. Straight-line loan: constant principal, falling payment. Bullet: interest only, full repayment at end.
Key Data and Facts
Annuity loan: most common for property. Straight-line loan: lower total interest than annuity. Bullet loan: high flexibility, often combined with life insurance. Effective APR: must be stated by law and includes all costs.
Step-by-Step Guide
Loan types compared: 1. Annuity: constant monthly payment; ideal for budget planning. 2. Straight-line: constant repayment + falling interest = falling total payment; lower total interest. 3. Bullet: interest only, lump sum at end; risk: final amount must be available.
Calculation Example
Loan 50,000 EUR, 5 % interest, 10 years: annuity 530.33 EUR/month, total interest 13,639 EUR. Straight-line loan: first payment 625 EUR, last payment 418.40 EUR, total interest 12,604 EUR (5 %/12 × 50,000 × 121/2). Bullet loan: 208.33 EUR interest per month, total interest 25,000 EUR.
