You sold a $25 cash-secured put and collected $250 premium. What's your return? 10%? 100%? 1%?
This is where most options traders get confused. The answer depends on what you use as your "capital deployed."
After tracking 500+ options trades and seeing how different traders calculate returns, I've learned there's a RIGHT way to do this—and about five wrong ways that will mislead you.
This guide covers how to calculate return on capital deployed correctly for cash-secured puts, covered calls, LEAPS, and full wheel cycles, with real examples and common mistakes.
What Is "Capital Deployed"?
Capital deployed is the actual cash you have tied up in a position—the money you can't use for anything else while the position is open.
It's NOT:
- The option premium
- The notional value
- Your total portfolio value
- Some made-up number
It's the real, actual cash your broker sets aside or requires you to have.
Why This Matters
Using the wrong denominator in your return calculation will make you think trades are more (or less) profitable than they actually are.
Example of bad math:
- Sell $25 CSP for $2.50 premium ($250)
- Wrong calculation: $250 / $250 = 100% return!
- Reality: You had $2,500 tied up, so 10% return
100% sounds amazing. 10% is still great. But thinking you're getting 100% returns will lead to bad decisions about position sizing and risk.
Return on Capital Formula
Basic Formula:
Return on Capital = (P&L / Capital Deployed) × 100%
Annualized Formula:
Annualized Return = Return on Capital × (365 / Days Held)
The tricky part is figuring out what "Capital Deployed" means for each strategy.
Cash-Secured Puts (CSPs)
Capital Deployed = Strike Price × 100 × # Contracts
When you sell a CSP, your broker sets aside cash equal to the strike price × 100. That's your capital deployed.
Example 1: Simple CSP
- Sell 1 PLTR $25 PUT for $250 premium
- Capital deployed: $25 × 100 = $2,500
- P&L: $250 (expires worthless)
- Return: $250 / $2,500 = 10%
- Days held: 30 days
- Annualized return: 10% × (365/30) = 121.7%
Example 2: Multiple Contracts
- Sell 3 NVDA $500 PUTs for $6,000 premium ($2,000 each)
- Capital deployed: $500 × 100 × 3 = $150,000
- P&L: $6,000
- Return: $6,000 / $150,000 = 4%
- Days held: 14 days
- Annualized: 4% × (365/14) = 104.3%
Common CSP Mistakes
Mistake 1: Using premium as capital
- Wrong: $250 / $250 = 100%
- Right: $250 / $2,500 = 10%
Mistake 2: Using stock price instead of strike
- Stock trading at $24, strike $25
- Wrong: $250 / $2,400 = 10.4%
- Right: $250 / $2,500 = 10%
Use strike price, not current stock price. That's what your broker uses.
Covered Calls
Capital Deployed = Stock Value (# Shares × Current Price)
When you sell a covered call, your capital deployed is the value of the shares backing it.
Example 1: Standard Covered Call
- Own 100 shares of AAPL at $180/share
- Sell 1 AAPL $185 CALL for $300 premium
- Capital deployed: 100 × $180 = $18,000
- P&L: $300 (expires worthless)
- Return: $300 / $18,000 = 1.67%
- Days held: 30 days
- Annualized: 1.67% × (365/30) = 20.3%
Example 2: Called Away
- Own 100 PLTR at $22.50/share (cost basis after assignment)
- Sell PLTR $27 CALL for $150 premium
- Called away at $27
- Capital deployed: 100 × $22.50 = $2,250 (your cost basis)
- P&L: $150 (premium) + $450 (stock gain: $27 - $22.50) = $600
- Return: $600 / $2,250 = 26.7%
- Days held: 21 days
- Annualized: 26.7% × (365/21) = 464%
Cost Basis vs Current Price
Which do you use for capital deployed?
It depends on your tracking philosophy:
Option A: Use cost basis (what you paid)
- Shows return on your actual investment
- Better for long-term holdings
- This is what I recommend
Option B: Use current value (market value)
- Shows opportunity cost (capital could be deployed elsewhere)
- Better for frequent traders
Be consistent. Don't switch methods mid-tracking.
Common Covered Call Mistakes
Mistake 1: Only counting premium, ignoring stock gain
- Wrong: $150 premium / $2,250 = 6.7%
- Right: ($150 premium + $450 stock gain) / $2,250 = 26.7%
If shares are called away, include the stock gain!
Mistake 2: Using strike price as capital
- Wrong: $150 / $2,700 (strike × 100)
- Right: $150 / $2,250 (your cost basis)
LEAPS (Long-Term Options)
Capital Deployed = Premium Paid × 100
For LEAPS (buy-to-open), your capital deployed is what you paid for the option.
Example 1: LEAPS Buy to Open
- Buy 1 NVDA $400 CALL (Jan 2027) for $5,300
- Capital deployed: $5,300
- Sell later for $6,800
- P&L: $6,800 - $5,300 = $1,500
- Return: $1,500 / $5,300 = 28.3%
- Days held: 90 days
- Annualized: 28.3% × (365/90) = 114.7%
Example 2: LEAPS Exercised
- Buy TSLA $150 CALL for $3,000
- Exercise when TSLA at $200
- Acquire 100 shares at $150 (strike)
- Total capital deployed: $3,000 (option) + $15,000 (exercise) = $18,000
- Current value: $20,000 (100 × $200)
- P&L: $2,000
- Return: $2,000 / $18,000 = 11.1%
Common LEAPS Mistakes
Mistake: Using notional value instead of premium paid
- Stock at $400, paid $53 for option
- Wrong: $1,500 / $40,000 (stock value) = 3.75%
- Right: $1,500 / $5,300 (premium paid) = 28.3%
Full Wheel Cycle
Capital Deployed = Initial CSP Capital (Strike × 100)
For a complete wheel cycle (CSP → Assignment → Covered Call → Called Away), use the original CSP capital as your denominator.
Example: Complete Wheel Cycle
Step 1: Sell CSP
- PLTR $25 CSP for $250 premium
- Capital deployed: $2,500
- Assigned
Step 2: Sell Covered Call
- PLTR $27 CC for $150 premium
- Capital still deployed: $2,500 (your cost basis: $2,250, but using original $2,500 for consistency)
- Called away at $27
Total P&L:
- CSP premium: $250
- Stock gain: ($27 - $22.50) × 100 = $450
- CC premium: $150
- Total: $850
Return on Capital:
- $850 / $2,500 = 34%
- Days: 55 days total (CSP entry to CC called away)
- Annualized: 34% × (365/55) = 225.5%
Alternatively, you can use the actual cost basis after assignment ($2,250):
- $850 / $2,250 = 37.8%
- Annualized: 37.8% × (365/55) = 250.7%
Both are valid. I prefer using the original CSP capital because it's simpler and doesn't change mid-cycle.
Multiple Positions: Portfolio Level Returns
Capital Deployed = Sum of All Capital Tied Up
Example: Multi-Position Portfolio
Open Positions:
- PLTR $25 CSP → $2,500 deployed
- NVDA $500 CSP × 2 → $100,000 deployed
- 100 AAPL shares ($180) with CC → $18,000 deployed
Total capital deployed: $120,500
Open P&L:
- PLTR CSP: +$200 unrealized
- NVDA CSPs: +$3,000 unrealized
- AAPL CC: +$250 unrealized
- AAPL shares: +$500 unrealized
Total open P&L: +$3,950
Return on capital deployed:
- $3,950 / $120,500 = 3.28%
This shows you're using $120,500 of your cash to generate $3,950 in current P&L.
vs Return on Portfolio Value
If your total portfolio is $200,000 but only $120,500 is deployed in options:
- Return on capital deployed: 3.28%
- Return on total portfolio: $3,950 / $200,000 = 1.98%
Which matters?
- Return on capital deployed: Shows effectiveness of your options strategy
- Return on total portfolio: Shows overall portfolio performance
Track both. They answer different questions.
Realized vs Unrealized Returns
Realized Returns (Closed Positions)
Realized Return = Total Realized P&L / Capital That Was Deployed
Only counts closed positions. This is your "locked in" return.
Unrealized Returns (Open Positions)
Unrealized Return = Current Open P&L / Currently Deployed Capital
Shows current profitability of open positions. Can change until closed.
Total Return (Realized + Unrealized)
Total Return = (Realized P&L + Open P&L) / (Historical Capital + Current Capital)
This gets complex if you're constantly opening/closing positions. Most traders track realized and unrealized separately.
Dashboard Metrics: What Options Tracker Shows
When you use Options Tracker, the dashboard calculates these automatically:
1. Return on Capital Deployed
(Total P&L) / (Capital at Risk Across All Positions)
Includes both realized and open P&L. Shows overall performance.
2. Realized Return
(Realized P&L) / (Sum of Capital from Closed Positions)
Only closed trades. This is your "bank".
3. Annualized Return
(Total Return) × (365 / Average Days Held)
Time-adjusted return. Lets you compare a 7-day trade to a 45-day trade fairly.
4. Return by Strategy
Separate calculations for:
- CSPs only
- Covered Calls only
- LEAPS only
- Full wheel cycles
Helps you see which strategies work best for you.
Common Mistakes Summary
| Mistake | Wrong | Right |
|---|---|---|
| CSP: Using premium as capital | $250 / $250 | $250 / $2,500 |
| CSP: Using stock price | $250 / $2,400 | $250 / $2,500 (strike) |
| CC: Ignoring stock gain | $150 / $2,250 | ($150 + $450) / $2,250 |
| CC: Using strike as capital | $150 / $2,700 | $150 / $2,250 (cost basis) |
| LEAPS: Using notional value | $1,500 / $40,000 | $1,500 / $5,300 (premium) |
| Wheel: Only counting one leg | $250 / $2,500 (CSP only) | $850 / $2,500 (full cycle) |
Real Example: My PLTR Wheel Cycle
Let me show you a real trade I tracked with correct return calculations.
Jan 25: Sold PLTR $25 CSP for $2.50 premium ($250)
- Capital deployed: $2,500
- Return so far: $250 / $2,500 = 10%
Feb 17: PLTR at $24, assigned 100 shares
- Cost basis: $22.50/share ($2,250 total)
- Capital deployed: Still $2,500 (original commitment)
- Return so far: 10% realized (CSP premium locked in)
Feb 18: Sold PLTR $27 CC for $1.50 premium ($150)
- Capital deployed: Still $2,500
- Return so far: ($250 + $150) / $2,500 = 16%
Mar 21: PLTR at $28, called away at $27
- Stock gain: ($27 - $22.50) × 100 = $450
- Total P&L: $250 + $150 + $450 = $850
- Final return: $850 / $2,500 = 34%
- Days held: 55 days
- Annualized return: 34% × (365/55) = 225.5%
That's the full calculation, step by step.
Tools for Calculating Returns
Option 1: Manual Spreadsheet
Track each position with:
- Capital deployed column
- P&L column
- Return % formula: =P&L / Capital
- Days held column
- Annualized return: =Return × (365 / Days)
Option 2: Options Tracker (Automatic)
Options Tracker calculates all of this automatically:
- Capital deployed tracked per position
- Return on capital calculated in real-time
- Annualized returns for all closed positions
- Dashboard shows aggregate metrics
- Compare by strategy, ticker, or account
No formulas, no manual calculations, no errors.
Conclusion
Calculating return on capital deployed correctly is critical for understanding if your options strategies are working.
Key formulas:
- CSPs: Capital = Strike × 100
- Covered Calls: Capital = Shares × Cost Basis
- LEAPS: Capital = Premium Paid
- Wheel Cycles: Capital = Original CSP Capital
- Annualized: Return × (365 / Days Held)
Most important: Be consistent. Use the same methodology for every trade, and you'll be able to compare performance accurately.
