Business Plan Calculator?

[missy]

I am wondering if anyone knows of a business calculator online? Like for a start-up daycare center/business plan to assess the costs/profits/break-even point, etc. There seem to be calculators online for anything these days, but I can't find what I'm looking for. I did one myself but it would be nice to see an official one to make sure I'm not forgetting any costs!

Thanks!
