Is compound interest halal? Yes — only riba (interest on a loan) is prohibited, not the growth of capital invested in the real economy. The investments themselves still have to be compliant.

This calculator illustrates a mathematical mechanism for educational purposes. The return entered is an assumption and not a promise: past performance is not a reliable indicator of future performance. All investment carries a risk of capital loss. Results are given before inflation, fees and taxation. It does not constitute investment advice within the meaning of the LSFin.

Why compound interest changes everything

The principle of compound interest is one of the most powerful in finance: when one year's gains are reinvested, they in turn generate gains the following year. Capital no longer grows in a linear way, but exponentially. Over a long horizon, the gap becomes striking — that is what the chart above makes visible.

A starting capital of 10'000 CHF, topped up by 500 CHF a month for 20 years at an average return of 6 %, reaches far more than the simple sum of the contributions: the difference is compound interest. The earlier you start, the more this effect works in your favour — time is your best ally in investing.

Going further

Capital that grows is good. Well invested, it is better.

This simulator shows the potential. What remains is knowing how to choose the right investments yourself. The ALG Club programme teaches you to turn a projection into a method you apply yourself — presented during a first conversation, with no obligation.
