Compounding Calculator

Dollar-cost averaging (DCA) — investing the same amount on a regular schedule regardless of price — is the single most reliable way ordinary investors have built wealth across every asset class for the last hundred years. It works for one reason: it removes the most expensive thing you ever do, which is try to time the market.

For halal crypto specifically, DCA has an additional advantage. Crypto returns are highly non-normal — most of the gain in any given cycle comes from a small number of weeks. If you sit out hoping for a better price, you usually miss the up-weeks and buy after them. DCA quietly catches those weeks alongside everything else.

The compounding calculator shows you what this looks like in numbers. The first two years are unimpressive. The fifth year starts to bend. The tenth year — and especially the curve between year 10 and year 20 — is where most of the wealth actually accumulates. Patience is the price of compounding.

A subtle point most general compounding calculators miss: Muslims cannot use a high-interest savings account or a bond ladder as their compounding engine. Riba is haram regardless of the rate. That removes a category of tools that secular investors rely on heavily.

What replaces it is asset-based compounding — buying real ownership in productive assets and letting their cashflows or appreciation do the compounding for you. Halal crypto fits this mould: a spot purchase is direct asset ownership, not a debt instrument. Returns come from the asset, not from a lender promising you interest.

The other consideration is zakat. Long-held halal crypto positions are typically zakatable annually at 2.5% of value. That's not modeled in this calculator — most users discharge zakat from outside the portfolio so the compounding engine itself stays intact.
