FINRA Series 7 options calculations

Option contracts and the customer position

Start every Series 7 option question by identifying the underlying, call or put, long or short, strike, premium, expiration, and number of contracts. The buyer has a right; the writer has an obligation if assigned. A call gives its holder the right to buy at the strike, while a put gives the right to sell. Premium is paid by the buyer and received by the writer.

A standard listed equity option generally represents 100 shares. Premiums are quoted per share, so a 2.10 premium costs 210 dollars for one contract before fees. Solve per share first, then multiply by contracts and 100. Do not multiply the strike by 100 unless calculating the total share value involved in exercise.

Intrinsic value and time value

A call is in the money when market price exceeds strike; intrinsic value is market price minus strike. A put is in the money when strike exceeds market price; intrinsic value is strike minus market price. An out-of-the-money option has no intrinsic value. Before expiration, premium can still include time value from remaining life and volatility.

At expiration, option value is intrinsic value, if any. A buyer’s maximum loss is the premium paid. A call buyer can gain as the stock rises, while an uncovered call writer can face theoretically unlimited loss. A put buyer’s profit is bounded by the underlying falling toward zero; a put writer can incur substantial loss if the underlying declines sharply.

Breakeven and maximum gain or loss

For a long call, breakeven at expiration is strike plus premium. Profit begins above that point. For a long put, breakeven is strike minus premium, and profit begins below it. Premium must be included. Breakeven is not the same as strike.

For a short call, the writer’s breakeven is strike plus premium received. For a short put, breakeven is strike minus premium received. Premium reduces the writer’s loss or increases return but does not remove the obligation. In every question, state whether the customer bought or wrote the option.

For vertical spreads, compare strike width with net premium. A debit spread has maximum loss equal to net debit and maximum gain equal to strike width minus debit. A credit spread has maximum gain equal to net credit and maximum loss equal to width minus credit. Debit means paid; credit means received. Then multiply per-share outcomes by 100 for one equity contract.

Core option strategies

Covered call

A covered call combines long stock with a short call on the same shares. The premium provides limited income and lowers effective stock cost. The short call caps upside above its strike because the writer may have to sell shares there. If the stock falls, the premium cushions only part of the loss; it does not protect the whole stock position.

Protective put

A protective put combines long stock with a long put. The put gives the right to sell shares at the strike and establishes a floor through expiration, net of premium. This hedge costs money and can expire unused. Think of it as insurance: the customer retains upside but pays a premium to limit downside below the strike.

Straddles and combinations

A long straddle buys a call and a put at the same strike and expiration. It benefits from a sufficiently large move either way, but the combined premiums create two breakeven points. A short straddle receives premium but can lose heavily if the underlying moves sharply. A combination may use different strikes or expirations; map each leg before combining payoff.

Spreads

A spread combines options on the same underlying but with different strikes or expirations. For a vertical spread, strike width bounds payoff before costs. A bull call spread is usually a debit position with limited upside and loss. A bear put spread is also commonly a debit position and profits from a decline within defined limits. Read the actual legs instead of relying on a strategy name alone.

Original worked questions

Long call profit

A customer buys one ABC 50 call for a premium of 3 dollars. At expiration, ABC is 57 dollars. Intrinsic value is 7 dollars per share. Subtract the 3-dollar premium: profit is 4 dollars per share, or 400 dollars for one standard contract before fees. Breakeven is 53 dollars. Maximum loss is 300 dollars if ABC finishes at or below 50.

A 700-dollar answer reports intrinsic value but ignores premium. A 100-dollar answer may subtract the wrong values. A 53-dollar answer is breakeven, not profit. Separate intrinsic value, premium, and contract multiplier before selecting an answer.

Long put breakeven

A customer buys one LMN 40 put for 2.50 dollars. At expiration, LMN is 34 dollars. Intrinsic value is 6 dollars per share; after premium, profit is 3.50 per share or 350 dollars. Breakeven is 37.50 dollars, equal to strike minus premium. Maximum loss is 250 dollars if the stock closes at or above 40.

A put buyer benefits as the underlying falls. An answer showing loss growing without bound as LMN falls describes a put writer, not the buyer. A 600-dollar profit likely forgot to subtract the premium.

Credit spread maximum loss

A customer sells one 60 call and buys one 65 call on the same stock and expiration, receiving a net credit of 1.20 dollars. Maximum gain is the 120-dollar net credit. Strike width is 5 dollars per share, or 500 per contract. Maximum loss is width minus credit: 3.80 per share, or 380 dollars. Breakeven is 61.20. The short lower-strike call creates the obligation.

A 500-dollar maximum gain confuses width with credit. A 120-dollar maximum loss ignores the amount due if the stock rises. Write net credit and width first, then apply the credit-spread formulas.

Exercise, assignment, and taxes

Exercise and assignment are different events. The holder chooses whether to exercise a right, subject to contract terms; an assigned writer must fulfill the obligation. American-style options generally can be exercised before expiration; European-style options generally can be exercised only at expiration. The outline also includes settlement, contract adjustments, OCC, and tax treatment for equity, index, foreign-currency, and yield-based options.

Tax consequences can depend on the option class, strategy, holding period, exercise, assignment, and underlying. An exam question may state facts that determine the result. Avoid generalizing from one equity option to every contract. A useful study chart records transaction, event, and tax concept named in the outline, then practices distinguishing those cases.

Use a repeatable calculation routine

Write the position; mark strike and premium; determine expiration value; calculate per-share gain or loss; multiply by shares and contracts; then check maximum gain and loss. For spreads, calculate net debit or credit and strike width before payoff. This sequence avoids mixing a quoted premium with the total cost of a contract.

Estimate first. A long call buyer cannot lose more than premium; any answer showing a larger loss is impossible. A covered call cannot gain unlimited upside above the strike because shares may be called away. A protective put loses less in a sharp decline than unhedged stock, but the option cost reduces return. Direction checks catch errors before final arithmetic.

Draw an expiration diagram when a position has multiple legs. Mark each strike, plot the payoff for each contract, and combine the lines. This is useful for spreads and straddles where naming the strategy may hide its breakeven range. A short sketch often prevents a sign mistake more quickly than recomputing from memory.

After a practice miss, label the cause: premium omitted, position reversed, wrong strike, wrong expiration price, or multiplier error. Rework a new problem with changed values. If the error is in rights and obligations, rehearse that distinction before doing arithmetic. A method that transfers to new figures is stronger preparation than memorizing an answer.

Interpret payoff before choosing a strategy

A strategy name is shorthand, not a substitute for payoff analysis. A candidate should identify each leg and then ask what happens when the underlying rises, falls, or finishes near the strike. A protective put preserves upside but costs premium. A covered call receives premium but gives away some upside. A long straddle needs movement large enough to cover both premiums. These comparisons help answer questions that ask for the likely outlook or risk.

For a bull call spread, the lower-strike call is bought and the higher-strike call is sold. The debit is the maximum loss, and the spread width less debit is maximum gain. For a bear call credit spread, the lower-strike call is sold and the higher-strike call is bought. Credit is maximum gain; width less credit is maximum loss. If a prompt changes one leg, recalculate the net premium rather than relying on a memorized label.

The contract multiplier makes a small per-share outcome meaningful. A 0.75-dollar net premium is 75 dollars for one contract. A 2-dollar spread width represents 200 dollars before subtracting or adding premium. Write all payoffs per share first and label the final amount as per contract. This avoids confusing dollar figures that otherwise look plausible.

Pay attention to whether a question asks for outcome at expiration or before expiration. Before expiration, time value may remain and an option can trade above intrinsic value. A payoff calculation at expiration uses intrinsic value only. Do not use an expiration formula when the scenario is about an option sale today unless the question instructs you to assume expiration.
