Yeast starter question

[FlapjackAM]

So I've convinced the wife to let me get a new piece of brewing equipment, so I've decided to start doing starters. I get the process, my question is on the math. The pitch rate calculator changes the necessary cell count based on OG (obviously) so is there a rule of thumb that says a 1L starter boosts your cell count by x amount of cells? A 2L starter? With a baseline of 100 billion with wyeast how do I know I've added the acceptable amount?

Hope that makes sense.

Use the Mr. Malty calculator. It tells you how big a starter you need.

I got the app but it's confusing me. I'm making an IPA next week, last time I made it it had an OG of 1.066, 5 gal. volume, and for calculating purposes I made the yeast about a month old. Says I need 228 bil cells, sounds reasonable. but it says to put 2 vials in a 1 liter starter. That doesn't sound right to me. What am I doing wrong?

You can do 1 pack with a bigger starter volume and time. I like to use http://yeastcalc.com myself

Agreed..increase your volume if needed based on the info avail using either mrmalty or yeastcalc. Don't let the larger starter concern you, just be sure to account for it in your overall production volume.

Thanks everyone, think I figured it out.
