How much does it cost to hedge my stock with a protective put, and what's my maximum loss?

How this is calculated

• Total premium paid equals the premium per share, multiplied by 100, multiplied by your number of contracts. This is the fixed cost of the hedge, paid regardless of what the stock does.
• Your floor price per share, if you exercise the put at expiration, equals the strike price minus the premium you paid. That's the worst-case effective sale price on the hedged shares.
• Maximum loss per hedged share equals your cost basis minus that floor price. If the strike minus premium is already above your cost basis, the hedge locks in a guaranteed minimum profit instead of a loss, and the tool shows that case separately.
• Breakeven stock price equals your cost basis plus the premium paid, since the premium adds to your effective cost on the unlimited-upside side of the position.
• If your contracts cover fewer shares than you own, the unhedged shares carry full downside risk with no floor. The tool flags this.
