How compounding works
Each period you earn a gain on the new, larger balance, not just the original. That is compounding: growth feeding on growth. The formula is simple but the result is not intuitive.
A reality check
Compounding cuts both ways. The same math that grows a balance shrinks it on losing streaks, and consistent per-period gains are far harder to achieve than a calculator suggests. Use this to set realistic targets, not to plan guaranteed riches. Pair it with the Stop Loss Calculator to protect the balance you are compounding.

Common questions
- What counts as a period?
- Whatever you trade on: a day, a week, or a month. The gain percentage is applied once per period.
- Is a fixed percentage realistic?
- It is a model, not a promise. Real returns vary and losing periods reduce the balance. Use conservative numbers.
- Does it account for losses?
- This projects a steady gain. For risk on the downside, size each trade with the stop loss and position tools.
