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.
