Looking for a option strategy calculator

I am looking for an option strategy calculator - say Calendar spreads/Credit Spreads. I want to be able to plug in values and plot charts. Would you recommend any commercially available addins?

The strategy tester

I would love to be the tester. I actually intend to place these trades, so there is bottomline impact and trust me, I will test WELL :)

I was thinking of a small web page to do this
- First decide on the strategy based on my opinion of the stock - Strongly bullish (Credit PUT spread), Time Directional (Calendar Spread), Mildly bullish (Debit call spread)

- Then a screen to enter the multiple instruments - the eq and derivatives. (How do we get the prices on these?)

- Then the calculation of the actual loss and gain and the charting
