Use this calculator to explore how a starting balance could change under a fixed hypothetical return, payment schedule, and reinvestment rule. It separates money kept in the active balance from money withdrawn, so the result is easier to understand than a single oversized total.

Trader's Profit Calculator
Model simple or reinvested returns over a chosen schedule and inspect every period in the calculation.
Important: This calculator illustrates scenarios from your inputs. It is not a forecast, promise of profit, or investment advice.
How the trader’s profit calculator works
Enter a starting amount, a return per payment period, the number of periods, and how often the calculation should occur. If you enable compounding, choose what percentage of each period’s profit is reinvested. The remainder is recorded as a withdrawal rather than being added to the active balance.
For each period, the calculator uses the active balance at the start of that period:
- Period profit = active balance × return per period
- Reinvested amount = period profit × reinvestment percentage
- Withdrawal = period profit − reinvested amount
- Next active balance = active balance + reinvested amount
The detailed schedule shows every step instead of hiding the calculation behind one final number. You can compare no compounding, partial reinvestment, and full reinvestment without changing the underlying assumptions.
Compounding versus withdrawing profit
Compounding means leaving some or all calculated profit in the active balance. This increases the base used in later periods, so gains and losses can both become larger. Withdrawing profit keeps the modeled active balance lower and records the removed amount separately.
Neither choice creates an edge or predicts future performance. The calculator assumes the same return every period only to illustrate the mathematics. Real trading results are uneven, losing periods occur, costs and spreads may apply, and products can have different payout rules.
Choose the period carefully
A 2% return per day is not the same assumption as 2% per month. The selected frequency describes how the schedule is dated; the rate you enter is applied once per calculated period. Weekday mode skips Saturdays and Sundays, but it does not know market holidays or the availability of a particular instrument.
For a useful scenario, base the rate and number of periods on a clearly defined historical sample or a deliberately conservative hypothetical. Avoid turning a short winning streak into a long-term forecast.
Reading the results
The calculator reports four different values:
- Ending active balance: the amount still included in the model after reinvestment.
- Total withdrawals: calculated profit that was not reinvested.
- Total generated profit: reinvested profit plus withdrawals.
- Combined value: ending active balance plus withdrawals.
Keeping these values separate avoids a common mistake: treating withdrawn money as if it were still compounding inside the account.
Important limitations
This is an educational scenario calculator, not a forecast, signal, or promise of returns. It does not estimate the probability of achieving the entered rate. It also does not automatically include losses, fees, slippage, taxes, changing payouts, deposit or withdrawal restrictions, or currency conversion.
Use the output to compare assumptions, then stress-test the idea with lower returns, non-compounding periods, and a shorter horizon. Never risk money you cannot afford to lose.
Frequently asked questions
Does the calculator predict how much I will earn?
No. It calculates the arithmetic outcome of the assumptions you enter. It does not determine whether those assumptions are realistic or likely.
What does partial reinvestment mean?
Partial reinvestment adds only the chosen percentage of each period’s calculated profit to the active balance. The rest is counted as a withdrawal.
Why can compounding change the result so quickly?
Each reinvested amount changes the base for the next period. Over many periods, that repeated multiplication can produce a large mathematical difference. The same scaling effect can increase exposure when actual results include losses.
Does weekday mode include public holidays?
No. It skips Saturdays and Sundays only. Verify exchange holidays, broker schedules, and instrument availability separately.
