Covered Call

Computes the outcome of a covered call: holding a stock and selling a call on it to collect the premium. It's the most popular income strategy in the options market: you earn the premium now in exchange for capping your profit at the strike. The tool returns the maximum profit (if the stock is called away), the percentage return in that case, the breakeven and the maximum loss. Enter the stock price, the strike of the call sold and the premium received.

Covered Call

Computes the outcome of a covered call: holding a stock and selling a call on it to collect the premium. It's the most popular income strategy in the options market: you earn the premium now in exchange for capping your profit at the strike. The tool returns the maximum profit (if the stock is called away), the percentage return in that case, the breakeven and the maximum loss. Enter the stock price, the strike of the call sold and the premium received.

Turning idle shares into income

Got a stock portfolio you plan to hold for a while and don't mind selling if it rises a bit? The covered call turns that into income. You sell a call on shares you already own and collect the premium right away. If the stock doesn't reach the strike, the premium is yours and you repeat the process next month.

The strategy's cost is the ceiling. If the stock shoots well above the strike, you're assigned and sell at the agreed price, leaving the rest of the rally on the table. That's why the covered call shines in sideways or moderately rising markets, not in moonshots. The premium also offers a little protection: it lowers your breakeven price.

Enter the stock price, the strike of the call sold and the premium received. The tool returns the maximum profit if the stock is called away, the percentage return in that scenario, the breakeven and the maximum loss if the stock goes to zero. Compare the return-if-called with what you'd be happy to earn to decide whether the strike makes sense.

Iron Condor

Computes the outcome of an iron condor: selling a put spread and a call spread at the same time, collecting a net credit. It's the classic strategy for betting the asset will trade sideways while pocketing the premium with limited risk. The tool uses the credit received and the four strikes to return the maximum profit (the credit itself), the maximum loss and the two breakeven points. Enter the four strikes and the net credit received.

Long Call Condor

Computes the outcome of a long call condor: buy one low-strike call, sell two middle-strike calls and buy one high-strike call. It's a cousin of the butterfly with a wider profit zone: you bet the asset will stay within a range rather than land exactly on a point. The tool returns the net cost, the maximum profit, the maximum loss and the two breakeven points. Enter the four strikes and the four call premiums.

Protective Put

Computes the outcome of a protective put: holding a stock and buying a put as insurance against a fall. The put sets a floor on the loss but costs the premium, which raises the breakeven. It's the most direct insurance for a long position: the upside stays unlimited, the downside is capped. The tool returns the maximum loss and the breakeven. Enter the stock price, the put strike and the premium paid.

Floating-Strike Lookback Call

Computes the price of a floating-strike lookback call with the Goldman-Sosin-Gatto formula: an option that pays the difference between the final price and the lowest price observed during the contract's life. In practice, it's like buying at the best possible price in hindsight, which makes it expensive but eliminates the risk of mistiming the purchase. It requires a positive interest rate. Enter the spot price, the observed minimum, the interest rate, the volatility and the term.

Iron Butterfly

Computes the outcome of an iron butterfly: selling a call and a put at the same central strike (the body) and buying a further-out call and put (the wings), collecting a net credit. It's a strong bet that the asset will finish right at the central strike, with a bigger credit than an iron condor but a narrower profit range. The tool returns the maximum profit, the maximum loss and the two breakeven points. Enter the central strike, the wing width and the credit received.

Long Straddle

Computes the cost and breakevens of a long straddle: buying a call and a put at the same strike and expiry. It's the classic volatility bet — you profit if the asset moves a lot in either direction, regardless of which way, and lose at most the premium paid if it stays put. The tool sums the two premiums and works out how far from the strike the asset must move to break even. Enter the strike and the call and put premiums.
