Long Call Butterfly Spread
Computes the outcome of a long call butterfly: buy one low-strike call, sell two middle-strike calls and buy one high-strike call, with equally spaced strikes. It's a bet that the asset will sit near the middle strike at expiry. The tool returns the net cost (debit), the maximum profit, the maximum loss (capped at the debit) and the two breakeven points.

Long Call Butterfly Spread
Computes the outcome of a long call butterfly: buy one low-strike call, sell two middle-strike calls and buy one high-strike call, with equally spaced strikes. It's a bet that the asset will sit near the middle strike at expiry. The tool returns the net cost (debit), the maximum profit, the maximum loss (capped at the debit) and the two breakeven points. Enter the three strikes and the three call premiums.
The bet that nothing will happen
Most option strategies bet on a direction: it'll go up, it'll go down. The butterfly bets the opposite, that the asset will stay roughly where it is. You build three legs with calls: buy one at a low strike, sell two in the middle and buy one at a high strike. The maximum profit happens if, at expiry, the price lands exactly on the middle strike.
The appeal is the limited risk on both ends. Since the cost of setting up the position is small, the maximum loss is too, and it never exceeds what you paid to get in. In exchange, the profit also has a ceiling: the gap between the strikes minus the cost. It's a low-volatility strategy, suited to when you think the market will go quiet.
The tool asks for the three strikes and the three call premiums and returns the net cost, the maximum profit, the maximum loss and the two breakeven points, the prices between which the position turns a profit. For the calculation to make sense, use equally spaced strikes, which is the classic butterfly setup.

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.
Bull Put Spread
Computes the outcome of a bull put spread: selling a higher-strike put and buying a lower-strike put, collecting a credit. It's a bullish (or neutral) bet that pockets the premium with risk capped by the bought put. The tool returns the credit received (maximum profit), the maximum loss and the breakeven. Enter the two strikes and the respective put premiums.
Bear Put Spread
Computes the outcome of a bear put spread: buying a higher-strike put and selling a lower-strike put, paying a debit. It's a bearish bet with limited risk and cost — cheaper than buying the put alone, in exchange for a capped profit. The tool returns the cost (debit), the maximum profit, the maximum loss and the breakeven. Enter the two strikes and the respective put premiums.
Collar (Protective Collar)
Computes the outcome of a collar: holding a stock, buying a put as a protective floor and selling a call as a ceiling, using the call premium to fund the put. It's the cheap way to protect a gain without closing the position — in exchange, you give up the upside above the ceiling. The tool returns the net option cost, the maximum profit, the maximum loss and the breakeven. Enter the stock price, the put and call strikes and the two premiums.
Calendar Spread
Computes the net debit of a calendar spread, also called a horizontal spread: selling a short-dated option and buying a longer-dated one at the same strike. The strategy exploits the fact that the short option loses value to time (theta) faster than the longer one. The result is the cost of setting up the position. Enter the premium of the short option sold and that of the long option bought.
Long Strangle
Computes the cost and breakevens of a long strangle: buying a lower-strike put and a higher-strike call, both out of the money. It's a cheaper volatility bet than the straddle, because out-of-the-money premiums cost less — in exchange, the asset has to move further to turn a profit. The tool sums the premiums and works out the two breakeven points. Enter the put and call strikes and their premiums.
