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.
