The T-Chart Method for Options Calculations
The T-chart is the single most useful tool for solving options calculations on the Series 7. Instead of memorizing a different formula for every strategy, you use one consistent method that works for any options position: single-leg, spread, straddle, or combination.
How the T-Chart Works
Draw a T with two columns:
| Money Out (Debits) | Money In (Credits) |
|---|---|
| Premiums paid to buy options | Premiums received from selling options |
| Money spent to buy stock (exercise/assignment) | Money received from selling stock (exercise/shares called away) |
Calculate the result:
- If Money In > Money Out = Gain
- If Money Out > Money In = Loss
- If Money In = Money Out = Breakeven
Think of it this way: Money Out is anything leaving your pocket (buying options, buying stock). Money In is anything coming into your pocket (selling options, selling stock). Subtract the smaller from the larger, and whichever column wins tells you profit or loss.
Note: Options contracts represent 100 shares. The T-chart examples below use per-share amounts for clarity, but multiply by 100 for total dollar profit or loss.
Exam Tip: Gotchas
- Buying stock through exercise goes in Money Out, not Money In. Students sometimes put exercise on the wrong side because they associate "exercise" with getting something. Focus on the cash flow: if cash leaves, it is Money Out.
Applying the T-Chart to Spreads
Enter all premiums paid and received. If both options are exercised, enter the stock bought (Money Out) and stock sold (Money In) at their respective strike prices.
Example: Bull Call Spread - Buy 1 XYZ Oct 50 call at 5 / Sell 1 XYZ Oct 60 call at 2
At max gain (stock at $60 or above, both exercised):
| Money Out | Money In |
|---|---|
| $5 (premium paid for 50 call) | $2 (premium received for 60 call) |
| $50 (buy stock at strike via 50 call) | $60 (sell stock at strike via 60 call) |
| Total: $55 | Total: $62 |
Result: $62 - $55 = $7 gain (max gain)
At max loss (stock at $50 or below, both expire worthless):
| Money Out | Money In |
|---|---|
| $5 (premium paid) | $2 (premium received) |
| Total: $5 | Total: $2 |
Result: $5 - $2 = $3 loss (max loss = net debit)
Breakeven: $50 strike + $3 net debit = $53. At $53, the long call gains $3 of intrinsic value, exactly offsetting the net premium paid.
Exam Tip: Gotchas
- For debit spreads, max loss = net premium paid. If both options expire worthless, you only lose the net debit. The short leg's premium partially offsets the long leg's cost.
- Breakeven on a bull call spread = lower strike + net debit. On a bear put spread, breakeven = higher strike - net debit.
Applying the T-Chart to Straddles and Combinations
Enter all premiums (two premiums for a straddle or combination). Then determine which option is exercised based on the stock price scenario. Only one leg is typically exercised (the in-the-money option); the other expires worthless.
Example: Long Straddle - Buy 1 XYZ Oct 50 call at 4 / Buy 1 XYZ Oct 50 put at 3
Stock at $60 (call is in the money, put expires worthless):
| Money Out | Money In |
|---|---|
| $4 (call premium) | $60 (sell stock at market) |
| $3 (put premium) | |
| $50 (buy stock via call exercise) | |
| Total: $57 | Total: $60 |
Result: $60 - $57 = $3 gain
Stock at $50 (both options at the money, max loss):
| Money Out | Money In |
|---|---|
| $4 (call premium) | $0 |
| $3 (put premium) | |
| Total: $7 | Total: $0 |
Result: $7 - $0 = $7 loss (max loss = total premiums paid)
Breakevens: A long straddle has two breakeven points:
- Upside breakeven: $50 + $7 = $57 (strike + total premiums)
- Downside breakeven: $50 - $7 = $43 (strike - total premiums)
Exam Tip: Gotchas
- Long straddles have two breakeven points, not one. Add total premiums to the strike for the upside breakeven; subtract total premiums from the strike for the downside breakeven.
- For a long straddle, max loss occurs when the stock sits exactly at the strike price. Both options expire worthless, and the buyer loses all premiums paid. The stock does not need to move to zero for a loss to occur.
T-Chart Rules
- Premiums paid always go in Money Out
- Premiums received always go in Money In
- Buying stock (through exercise or assignment) goes in Money Out
- Selling stock (through exercise or shares being called away) goes in Money In
- Compare totals to find profit or loss
- The T-chart works for every options strategy: spreads, straddles, combinations, covered writes, and uncovered positions
Exam Tip: Gotchas
- Assignment and exercise go on the same side. Whether you exercise your option or get assigned on a short option, the cash flow direction is the same: buying stock is always Money Out, selling stock is always Money In.
- The T-chart replaces formula memorization. If an exam question involves a complex multi-leg position, set up the T-chart rather than trying to recall a specific formula. The method is the same regardless of the strategy.
