Compound Interest Calculator
Project how your funded account grows month by month. Set your expected return, term, profit split and withdrawals — and see how much the compounding effect adds versus flat income.
Input
Up to 60 months (5 years).
The share of profit you keep. The standard at prop firms is 80–90%.
A fixed amount you withdraw each month. What you withdraw stops compounding; what you leave in the account keeps growing.
