Here you can easily calculate either the seed capital, the maturity, the interest rate or the Endkapital. To calculate easily fill all the fields except for that which you want to compute. The calculation takes into account the compounding of course.
|Seed||New Principal ÷ (1 + Rate Of Interest)Duration|
|Duration||ln(New Principal ÷ Seed) ÷ ln(1 + Rate Of Interest)|
|Rate Of Interest||((Endkapital ÷ Seed)(1 ÷ Duration) - 1) ⋅ 100|
|New Principal||Seed ⋅ (1 + Rate Of Interest)n|
