Compounding Calculator

Compounding means each trade’s gain is calculated on the new, larger balance — profits earn profits. At a fixed % per trade the balance grows exponentially, slow at first then explosively, which is why the equity curve hooks upward at the end.

No — and that is the lesson. The tool holds the gain rate constant, but no real strategy returns a fixed percentage every trade or day. Sustainable daily edges are roughly 1–5%; anything like 20%/day produces fantasy balances within weeks. Use it to feel the curve, not to plan returns.

You cap net realized losses per day, per week, or both at once — like a funded account that enforces a daily and an overall loss limit together. The cap can be a percentage of the balance at the start of that period (so it scales as the account compounds) or a flat dollar amount, whichever you prefer. As you log actual results in the Trade Ledger, the tool nets them per period: at 80% of a limit it warns you to size down, and once a limit is breached it tells you to stop trading and cool down until the next period. With both armed, a brutal single day can breach the daily cap even while the week still looks calm. Trades you haven’t logged never trigger an alert.

It lists the projected balance at every trade with an editable Date and Actual column. Log your real results to see whether you are keeping pace with the projection, and date each trade as you go — several trades can share one date. The Day, Week and Month views then aggregate the same run per period, blending your real results with the projection for trades you haven’t logged yet.

On a normal axis exponential growth crushes the early steps into a flat line against the towering tail. Log scale turns constant-percentage growth into a straight line, so every step stays readable.
