Trading Compounding Calculator
Project account growth when returns compound at a steady rate per period — monthly, weekly, or per any interval you choose — with the full period-by-period table. A constant rate is a simplification: real returns vary.

Frequently asked questions
How does compounding work in trading?
Gains earned in one period increase the base for the next, so growth accelerates: 5% per month is not 60% per year but 79.6%, because each month’s profit itself starts earning.
Is a fixed percentage per period realistic?
No trader earns exactly the same each period — this table is a projection device, not a forecast. It is most useful for comparing scenarios (e.g. 3% vs 5% monthly) and for seeing how quickly reinvested gains dominate.
Does compounding apply to prop firm accounts?
Partially. On funded accounts you typically withdraw profits rather than reinvest them, so within one account compounding is limited; scaling plans that grow your capital allocation are where the compounding effect actually shows up.
