Load calculator

Does anyone know of a tool that can help me calculate load for a deck design? I searched google pretty hard with no luck. I basically want to enter deck dimensions, size of wood I'm using and the desired load I can handle and have it spit out post spacing, etc....

Either that or can someone give me a quick refresher on how to calculate load? I knew I should have paid more attention to statics in college!

After quite a bit of searching I found this. Hopefully some others can find it useful too.

Ok, I punched in my numbers and it's saying that I can use 2x8 southern pine if I put my posts every 8' apart(ledger against house and then 8 posts), and then have my joists 16" apart.

Does that sound correct for 100 live and 20 dead on a 16x24 deck?
