How to use it

Enter your starting balance, the percentage you gain per period, and how many periods to compound. The calculator returns the final balance, your total return in dollars and percent, and the multiple your account grew by.

The math

final = start × (1 + rate)^periods. At 1% a day for 100 days, $1,000 becomes about $2,705 — a 2.7× multiple. That’s the power of compounding, and also why sustained high per-period returns are unrealistic: the same formula that grows an account explosively is why the numbers quickly become impossible to maintain in the real world.

Compounding cuts both ways

The same math applies to losses. A string of down periods shrinks the base you’re working from, so recovering requires a larger percentage gain than the percentage you lost. Respecting that asymmetry is what position sizing and risk management are for.

Frequently asked questions

How does compounding work in trading?

When you reinvest gains, each period’s return is earned on a larger balance than the last. Over many periods this snowballs: the final balance is the start times (1 + rate) raised to the number of periods. Small edges compound into large numbers — and so do losses.

Is 1% a day realistic?

As a math exercise, 1% a day for 100 trading days turns $1,000 into about $2,705. As a trading expectation it is not realistic to sustain — it implies consistency and a lack of drawdowns that virtually no trader achieves. Use this to understand the math, not as a target.

What counts as a period?

Whatever you want it to be — a day, a week, a trade, a month — as long as the gain rate you enter matches. The calculator just applies your per-period rate that many times.
