Frequently Asked Questions
What is a bond?
A bond is a debt security where you lend money to an issuer (government, company) for a fixed term. You receive regular interest payments (coupons) and the face value back at maturity.
How do interest rates affect bond prices?
Bond prices and interest rates move inversely. When interest rates rise, existing bonds with lower coupons become less attractive, and their market price falls. When rates fall, bond prices increase.
What is the Bond Calculator?
The bond calculator computes the yield (effective rate) of bonds, accounting for coupon, purchase price, term and redemption price.
How does the Bond Calculator work?
Enter the nominal value, coupon rate, purchase price and remaining term. The calculator determines the yield to maturity and the current yield. Accrued interest at purchase is taken into account.

Step-by-Step Guide
How to calculate die Anleiherendite step by step: 1. Nominalwert (Nennwert) enter: Ueblich 1.000 EUR oder 100 EUR. 2. Kuponzins enter: Der jaehrliche interest rate, den die Anleihe zahlt (z. B. 2,5 %). 3. Kaufkurs angeben: In Prozent des Nennwerts (z. B. 97 % = unter pari, 103 % = ueber pari). 4. Restlaufzeit enter: Jahre bis zur Faelligkeit der Anleihe. 5. Current Yield calculate: Kupon / Kaufkurs x 100. 6. Yield to Maturity (YTM) calculate: Beruecksichtigt Kupon plus Kursgewinn/-verlust bis Faelligkeit. Naeherungsformel: YTM = (Kupon + (Nennwert - Kaufpreis) / Restlaufzeit) / ((Nennwert + Kaufpreis) / 2). 7. Stueckzinsen beim Kauf beachten: Anteilige interest seit letztem Kupontermin. Beispiel: Bundesanleihe, Nennwert 10.000 EUR, Kupon 2,5 %, Kaufkurs 97 %, Restlaufzeit 5 Jahre. Kaufpreis: 10.000 x 0,97 = 9.700 EUR. Jaehrlicher Kupon: 250 EUR. Kursgewinn bei Faelligkeit: 300 EUR. YTM: (250 + 300/5) / ((10.000 + 9.700) / 2) = 310 / 9.850 = 3,15 %. Current Yield: 250 / 9.700 = 2,58 %.
Calculation Example
Bundesanleihe, Nennwert 10.000 EUR, Kupon 2,5 %, Kaufkurs 97 %, 5 Jahre Restlaufzeit. Kaufpreis: 9.700 EUR. Jaehrlicher Kupon: 250 EUR. YTM: ca. 3,15 %. Current Yield: 2,58 %.
