Hopville has a nice online recipe calculator: http://beercalculus.hopville.com/recipe. You can store your recipes on the site too which makes it very easy share your awesome creations with others :)

Jamil has a great pitching rate calculator on his site, which you might be interested in.

The Beer Recipator is another good one.

I am a fan of BeerSmith. Performs tons of calculations, maintains recipes, and all around is a handy tool to have. There is a trial version to get a feel for it, and for me it was well worth the cost to get the full version.

Have a look at captainbrew.com. You can create recipes, adjust gravity or bitterness, scale a recipe, create brew sessions and many more. There are also other calculators included like Yeast Pitching Rate, Priming Sugar, Keg Carbonation, ABV , Sparge Water, Washed Yeast.

The poster wants the formulas, not a recipe generator. Are you with Captainbrew? This is your second or third post where you include it in your answer? No big deal just asking. – brewchez Jan 19 at 17:23
