How compounding works

Compounding means each period’s return is earned on the new, larger balance, not just the original amount. The formula, without deposits, is:

Final balance = Starting balance × (1 + return per period) ^ number of periods

Example: $1,000 growing 2% a month for 24 months becomes about $1,608, not $1,480, because the gains themselves earn returns.

Why small differences matter

1% a month compounds to about 12.7% a year; 3% a month is about 42.6% a year; 10% a month is over 200% a year. That’s why compounding tables in trading ads look spectacular: they assume a high return every single period with no losing months.

Real trading returns are uneven. A losing month shrinks the base that future gains compound on, and a 50% loss needs a 100% gain to recover. See the drawdown calculator.

FAQ

How do I calculate compound growth in trading?
Multiply the starting balance by (1 + return per period) raised to the number of periods. With regular deposits, add each deposit after that period's growth.
How much is 1% a day compounded?
Over 252 trading days, 1% a day compounds to roughly 12 times the starting balance. Sustaining that is extremely rare; the figure shows the maths, not a realistic expectation.
How much is 2% a month compounded over a year?
About 26.8% a year, compared with 24% if the gains weren't compounded.
Can I include withdrawals?
Yes. Enter a negative number in the deposit field to withdraw that amount each period.
