YTM (Yield to Maturity) accounts for coupon payments, capital gain/loss and the time value of money. A purchase price below 100% means an additional capital gain at maturity.

FAQ
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.

Key Data and Facts
German 10-year government bond yield (2026): approx. 2.5-3.0%. Coupon interest is subject to flat-rate tax. Capital gains on bonds are also taxable.
Step-by-Step Guide
How to calculate the bond yield step by step: 1. Enter the nominal value (face value): typically 1.000 EUR or 100 EUR. 2. Enter the coupon rate: the annual interest rate the bond pays (e.g. 2,5 %). 3. Specify the purchase price: as a percentage of the face value (e.g. 97 % = below par, 103 % = above par). 4. Enter the remaining term: years until the bond matures. 5. Calculate the Current Yield: coupon / purchase price x 100. 6. Calculate the Yield to Maturity (YTM): it accounts for the coupon plus the price gain/loss until maturity. Approximation formula: YTM = (coupon + (face value - purchase price) / remaining term) / ((face value + purchase price) / 2). 7. Note the accrued interest on purchase: the pro-rata interest since the last coupon date. Example: German government bond, face value 10.000 EUR, coupon 2,5 %, purchase price 97 %, remaining term 5 years. Purchase price: 10.000 x 0,97 = 9.700 EUR. Annual coupon: 250 EUR. Price gain at maturity: 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 %.
