Short Call
There is no potential 'loss' on the options contract, but this trade creates 'opportunity risk'. If the stock price decreases significantly below the strike price of the sold Put, the trader misses out on that additional price decrease because she is obliged to buy 100 shares at the strike price.
The cost basis of the shares minus the current price of the shares plus the credit received for selling the Put. (Theoretically the loss can be infinite, here is a non-infinite example: you are short 100 shares of stock XYZ with cost basis $100 per share and you sell a $95P for $3. Stock XYZ goes to $200. Your loss is $10,000 (the cost of the shares) - $20,000 (the current price) + $300 (the credit received for selling the Put) = -$9,700.)
