Ränta-på-ränta: Den Eighth Wonder of the World
Compound interest is the most powerful mechanism for building wealth. När you reinvest your returns, you earn interest on your interest - and the effect accelerates over time.
Time Är Din Best Ally
Den earlier you start saving, the more compound interest works in your favor. Even small monthly amounts can grow into substantial sums over 20-30 years.
Return vs. Risk
Higher returns typically come with higher risk. Historical stock market returns average 7-8% per år before inflation, while savings accounts currently yield only about 1-2%.
Example: 200 Euro månadsvis Savings Plan
If you invest 200 euros monthly at an average return of 7% per år, after 30 years you will have accumulated approximately 227,000 euros - from only 72,000 euros of your own contributions.
