Expected Return
$5000.00
Final Balance

How is this calculated?
Expectancy = WinRate × R − (1 − WinRate) × 1
Expected Return = Balance × Expectancy × Trades × (Risk per Trade% ÷ 100)
Assumes the same Risk per Trade% on each trade and linear (non-compounded) growth.

How is per-trade return calculated?
Trade return expresses the outcome of a trade as a percentage of the capital at stake, which makes trades of very different sizes directly comparable. A $200 profit on a $2,000 position and a $200 profit on a $10,000 position are very different results — 10% versus 2% — and only the return makes that visible. It is the bridge between a single trade's outcome and the longer-term growth of your account, and the basic building block for compounding.
Key concepts
Return on trade
Profit or loss divided by the capital allocated to the trade.
Annualization
Scaling a return to a yearly basis for comparison across time frames.
A worked example with real numbers
- 1
Enter the trade outcome
You bought at $40 and sold at $44 on 100 shares, for a $400 gross profit. Fees cost $10, so net profit is $390.
- 2
Enter the capital at stake
The position cost $4,000, which is the capital this return should be measured against.
- 3
Divide net by capital
$390 ÷ $4,000 = 9.75%. That is the trade return — the number that makes this trade comparable to any other size.
- 4
Compare across trades
A $390 profit on $4,000 is 9.75%, far better than the same $390 on $10,000, which would only be 3.9%. The return, not the dollar, tells you efficiency.

Trade return
Return % = Net P&L ÷ Capital × 100%
Mistakes traders make
✗ Tracking only the dollar P&L and ignoring how much capital was used
✓Two $500 profits with different capital needs are different trades. Return per dollar at risk is what compounds your account.
✗ Using gross profit instead of net
✓An 11% gross return that becomes 9% after costs is the real result. Record the number you actually keep.
✗ Mixing return conventions between trades
✓If one trade measures return on full notional and another on margin, the two are not comparable. Pick one consistent base.
When this tool fits — and when it does not
Use it when
- ✓After every closed trade, to log a comparable performance number.
- ✓When deciding whether a traded return justifies the capital tied up.
- ✓When building a track record to evaluate your edge over time.
Skip it when
- ✗Comparing returns across trades measured on different capital bases.
- ✗Annualizing a single short trade and reading it as a yearly figure.
- ✗Judging a strategy from one or two outstanding trade returns.
Practical tips that actually help
Log the risked amount, not just the notional
If you risked $500 on the trade, measuring return against that $500 doubles the insight — it shows reward per unit of risk, which is closer to how pros think.
Keep a running average
Your average per-trade return across 50 trades is the number that compounds. A few outliers should not drive your sense of the edge.
Mind the base you choose
Be explicitly consistent — notional, margin, or risk — and write it down so you can read your own history later.

Frequently asked questions
Return vs absolute P&L — which to track?▾
Both. P&L tells you the money result; return tells you whether the result is efficient relative to the capital used.
What counts as the capital in the denominator?▾
That depends on your convention. Some traders use the full notional position, others the margin or the amount at risk. Be consistent, because the choice changes the percentage.
Why does return matter more than the dollar amount?▾
Dollars depend on account size. A percentage scales to any account, so it tells you whether the trade was good relative to what was put on the line — not just whether it made money.
Should I include costs in the return?▾
Yes. A gross return flatters every trade. Netting out commission, spread, and slippage gives the return you actually keep, which is the number worth tracking.
How does per-trade return connect to compounding?▾
Each trade's percentage gain or loss applies to the account balance at that moment. Consistent positive returns compound the base higher, while losses shrink the base the next return is calculated on.
