How your money grows with compound interest
Compound interest is one of the most powerful levers in long-term wealth building. Interest credited to your capital earns further interest in the following years. Over long periods this leads to exponential rather than linear growth.
Frequently asked questions
How does the compound interest calculator work?
Enter your initial capital, monthly contribution, annual interest rate and term. The calculator simulates the growth period by period and shows the final amount, total contributions and interest earned.
What is the compounding effect?
With compound interest, previously credited interest itself earns interest in later periods. As a result your capital grows exponentially – the longer the term, the stronger the effect.
Monthly or yearly interest crediting?
With monthly crediting, interest is calculated twelve times a year and reinvested, which slightly increases the final amount compared to yearly crediting.
