Compound Growth Calculator
See the exponential power of reinvested profits. Even a modest 5% monthly return turns $1,000 into $1,796 in just 12 months — and the curve only gets steeper.
Open Calculator →Overview
Compound growth is the single most powerful force in trading. When you reinvest your profits, each period's returns generate additional returns on top of previous gains, creating exponential growth that far exceeds linear expectations.
This calculator projects your account growth over time, with support for additional deposits, periodic withdrawals, and flexible compounding periods (per trade, daily, weekly, or monthly). An interactive chart compares compound growth vs simple growth to show exactly how much the compounding advantage is worth.

How It Works
The calculator uses the standard compound growth formula with additions for deposits and withdrawals:
FV = PV × (1 + r)^n + periodic deposits - periodic withdrawals
The "compounding advantage" metric shows how much extra money you make from compounding vs keeping returns flat. The Rule of 72 provides a quick estimate: divide 72 by your gain percentage to find how many periods it takes to double your money.
Who Is This For?
Traders who want to plan their long-term growth trajectory. Those exploring whether to withdraw profits or reinvest. Account managers modeling growth projections for clients. And anyone who needs the motivation of seeing what consistent returns look like when compounded over months and years.
