The financial forecast in a VC pitch presentation combines two different pieces of financial information in one chart. Still, you can treat them differently.
- The short term burn rate. This is information should highly precise and accurate. An investor is 100% sure she will "lose" this money. If you cannot be accurate, you probably do not have a clue what investment is required to build the company
- The long-term dream. There is no point specifying that you will have $50,342,784.12m sales in year 5. You just don't know and claiming that you do will lose you realism points. Explain to an investor why you think it will be ~$50m
