Bethany, still not clear on what you are asking for.
If you are after cap table/valuation/dilution 'forecasting' and 'what if" analysis then this one is good and simple: http://www.asoftwarestartupguy.com/2012/12/cap-table-calculator.html
Steve Blank has lots of good resources on his site http://steveblank.com
If you are looking to forecast operating numbers (something akin to income statement and balance sheet) that's custom to your business. My recommendation there is to use a 'bottom up' forecast, i.e. "each unit of product/service generates x revenue and the related fixed and variable costs at various dates in the future are Y". Much more tangible and believable that top down, i.e. "the market is $100 bizillion so if we just get 1%...." I would be happy to share ours, but it's so custom that it likely be more trouble for you than it's worth.
