About the Compound Growth Calculator
This calculator projects how a trading account grows when returns compound month after month. It applies final balance = starting balance × (1 + monthly return)^months, adding any monthly deposit at the start of each period so it compounds too. Use it to set realistic milestones, see how regular deposits accelerate growth, and understand why consistency beats chasing big months.
Frequently Asked Questions
How does compound trading growth work?
Each month your balance earns a return on the full balance, including prior profits, so gains build on gains. The formula is final balance = starting balance × (1 + monthly return)^months, plus any monthly additions compounded for their remaining months. Small steady returns turn into large totals over time.
Is a 5% monthly return realistic in trading?
5% per month compounds to roughly 80% per year, which is excellent and hard to sustain. The default is there to show the math, not as a target. Use your own honest, drawdown-adjusted average return for a projection you can actually rely on.
Do the monthly additions earn returns too?
Yes. Each monthly addition is added to the balance and then compounds at your monthly return for every month that follows. The calculator separates total profit from total contributed so you can see how much growth came from returns versus deposits.
