Trading Compounding Calculator
See how steady gains compound over time.
Compounding assumes profits are reinvested each period. Use realistic gains and remember losses compound too.
A trading compounding calculator shows how a consistent percentage gain per period grows your account when profits are reinvested. Enter your starting balance, the percentage gain per period, and the number of periods to see the final balance and total return. Compounding is powerful — but so is compounding losses, which is why risk control matters.

How does trading compounding work?
Final balance = starting balance x (1 + gain percent)^number of periods. Reinvesting a steady 5 percent over 20 periods turns $1,000 into about $2,653 — a 165 percent total return.
Are these returns realistic?
Use conservative, realistic numbers. Consistent small gains compound impressively, but no strategy wins every period. Model drawdowns too — our backtesting service does.
Does compounding increase risk?
It increases position sizes as the account grows, so absolute risk per trade grows even at a fixed risk percent. Keep risk discipline as the account compounds.
