Free Options Trading Calculators

Options are straightforward once you understand the payoff structure. Before putting on any position, you should know three things: where you break even, what the maximum gain is, and what happens if you're completely wrong. These calculators answer all three — for long calls, long puts, and the most common income strategy, the covered call.

The Options Breakeven Calculator is the most useful starting point. For a call, breakeven is the strike plus the premium. For a put, it's the strike minus the premium. Knowing your breakeven before you buy tells you exactly how much the stock needs to move in your favor just to return your money — anything less is a loss.

The Options Profit Calculator goes further, showing you your P&L at any given stock price at expiration. Enter the option type (call or put), strike price, premium, and number of contracts, then enter your target stock price to see the outcome. This is how professional traders think about options — in terms of specific price scenarios, not abstract probabilities.

For income traders, the Covered Call Calculator shows the full picture: maximum profit if the stock gets called away, your annualized return on the position, and the effective downside protection provided by the premium received.
