Bullet Loan

Bullet loan (endfälliges Darlehen): interest only during the term, the full principal in one payment at maturity.

Repayment type: bullet

Also known as: endfälliges Darlehen, Festdarlehen, interest-only loan, non-amortizing loan

Only interest is paid during the term; the whole principal falls due at maturity. Common for bridge financing, Schuldschein notes, bond-style corporate loans, and loans paired with a separate repayment vehicle such as a building-savings contract or a life insurance.

How it works

1. Formula

It=B0⋅rI_t = B_0 \cdot r At=Itfor t<nA_t = I_t \quad \text{for } t < n An=In+B0A_n = I_n + B_0

where B0B_0 is the principal, rr the interest rate per period, nn the number of periods, ItI_t the interest and AtA_t the installment in period tt. The balance never changes until the final installment.

2. With the terms

Interest=Principal⋅Rate per period\text{Interest} = \text{Principal} \cdot \text{Rate per period} Installment=Interest\text{Installment} = \text{Interest} Final installment=Interest+Principal\text{Final installment} = \text{Interest} + \text{Principal}

3. With the example numbers: 100,000 EUR, 4.00 % p.a. with one installment per year, 5 installments.

It=100,000⋅0.04=4,000.00I_t = 100{,}000 \cdot 0.04 = 4{,}000.00 A1=A2=A3=A4=4,000.00A_1 = A_2 = A_3 = A_4 = 4{,}000.00 A5=4,000.00+100,000=104,000.00A_5 = 4{,}000.00 + 100{,}000 = 104{,}000.00

Example

100,000 EUR at 4.00 % p.a., 5 years, one installment per year.

The bullet loan is the cheapest to carry and the most expensive overall: 20,000.00 interest against 12,313.55 for the annuity loan, because the full balance earns interest for five years.

The final installment is the risk of this type. LoanMonitor shows it as one row at maturity, so the portfolio dashboard reveals every year in which a bullet comes due.
