What Is Compound Interest and Why Does It Matter for Expats?
Compound interest means you earn returns not only on your initial investment but also on the interest already accumulated. This effect, often called the "eighth wonder of the world", causes your wealth to grow exponentially the longer you stay invested. For expats in Germany, this is especially relevant: whether you invest in ETFs, fixed deposits, or a private pension plan, compound interest is what turns moderate saving into real wealth building. Calculate your retirement gap to see how much capital you actually need to build.
How Do Expats in Germany Benefit From Compound Interest?
Germany offers several tax-advantaged investment vehicles such as Rürup pension, company pension (bAV), and flexible pension insurance. Combined with a global ETF portfolio, expats can maximize the compound interest effect. The Sparerpauschbetrag (tax-free allowance) of €1,000 (€2,000 for couples) lets you keep part of your capital gains tax-free. Beyond that, gains are subject to 26.375% capital gains tax, use our calculator with the tax option to see the difference. First calculate your net salary to know how much you can invest.
