The Assumptions tab holds five inputs: month-1 revenue, monthly growth, cost of sales as a percentage of revenue, fixed monthly costs and your starting cash. The Projection tab then builds all twelve months — revenue, cost of sales, gross profit, fixed costs, net profit, and a running opening-and-closing cash position — so you can see the business's shape month by month.
The Dashboard summarises year one: total revenue, total net profit, the lowest cash point (your funding gap, flagged red if it goes negative) and the closing cash at month twelve. Change any assumption and the whole projection and every headline recomputes — so you can test a slower start or a leaner cost base in seconds.
It's a clean planning model, deliberately simple. For a full, integrated three-statement model with a DCF valuation — the kind an investor or bank analyst builds — see the 3-Statement Financial Model.
