Pick covered call or cash-secured put, enter the stock price, strike, premium and days to expiration, and the calculator shows what the trade earns per cycle and what that is worth over a year. Everything runs in your browser; nothing is sent anywhere. How to use it Choose the strategy. The defaults update to a typical example for each. Enter the stock price today, the strike you are selling, the premium per share you collect, and the days to expiration. Fees are optional but matter on small trades. Read the cards: the return for one cycle, the annualized figures, your breakeven, and the premium you would need to reach the target return you typed in. If the number looks too good, check the warning under the cards. A high annualized yield almost always means a short expiration, a strike close to the stock price, or both, and those are the trades most likely to end in assignment. ...

Most blown-up options accounts did not pick bad trades so much as they traded too big. This calculator works out the largest position that stays inside two limits you set in advance: how much of your account one trade is allowed to lose, and how much capital one position is allowed to tie up. Everything runs in your browser; nothing is sent anywhere. How to use it Pick the trade type. Set your limits: account size, the percentage of the account you are willing to lose on a single trade, and the most capital you want in any one position. Many traders start with 1% to 2% risk per trade. Enter the trade: the debit paid, the spread width and credit, the put strike, premium and stop, or the stock entry and stop. Read the suggested size. It is the smaller of what the risk budget allows and what the position limit allows, rounded down. Rounding down is deliberate: it keeps you under your limit rather than slightly over it. How each trade type is measured Long option or debit spread. The most you can lose is the debit you pay, so risk and capital are the same number: debit times 100 per contract. ...

The wheel is simple to describe and surprisingly easy to lose track of: a few weeks of puts, an assignment, a few months of calls, a call-away, and then it starts over. After two or three turns most people cannot say what their real cost basis is. This tracker keeps a running ledger and does that arithmetic for you. Click Load example to see a finished wheel and a wheel in progress, then clear it and log your own trades. Your entries are stored in this browser only; nothing is uploaded, and you can export them as a CSV at any time. ...

Pick a strategy above, enter your strikes and premium, and the calculator updates max profit, max loss, and breakeven instantly — along with a payoff diagram showing profit and loss across a range of prices at expiration. Everything runs in your browser; nothing is sent anywhere. How to Use This Options Profit Calculator Choose your strategy from the dropdown (long call, long put, covered call, cash-secured put, credit spread, debit spread, or iron condor). Enter the strikes and the premium you paid or received, per share — the price shown on your trade ticket. Read the results: max profit, max loss, and breakeven update as you type. For iron condors and other multi-leg trades, you’ll see both breakeven points. Use the chart to see how profit and loss change as the underlying moves, not just at the two or three critical price points. All figures are calculated at expiration and assume standard 100-share option contracts. They don’t account for commissions, assignment fees, or early exercise — see the notes for each strategy below. ...
