📈 Revenue Projections Calculator
A revenue projection is a promise you make to yourself, so build it a month at a time instead of multiplying a dream by 12. Start from the sales you can win in month one, grow them at a rate you can defend, let repeat customers stack on top, and watch what the compounding actually asks of you by month 12.
The number you could realistically win in your first month, not your best month.
Month over month. 10 percent means 10 new-customer sales become 11 next month.
Keeps repeat dynamics simple: this percent of last month's buyers buy once more. Use 0 for one-time purchases.

10 percent monthly growth doubles your monthly sales roughly every 8 months; that is the deal you are signing up for. It means delivering about 35 sales in month 12 for $3,487 that month and $25,859 across the year. Hold the growth number honest against what you can actually deliver: the marketing to win those sales and the hours to serve them.

Good questions about this math
Is this the same as the How Much Can I Make calculator?
That one is the quick snapshot: sales times price at a single steady month, no growth. This is the detailed version, where sales compound month by month and repeat customers stack. Start there for the 30-second gut check, then come here when you want the year mapped out.
What monthly growth percent is realistic?
There is no universal number, and anyone who hands you one is selling something. Growth is a result of specific actions: so many outreach calls, so much ad spend, so many referrals. A common pattern worth knowing: percentage growth is easiest when the base is small (going from 10 to 12 sales) and gets harder every month as the base grows. If you cannot name what produces next month's increase, project 0 and let real months teach you your rate.
How does the repeat-customer number work?
Deliberately simply: each month, that percent of last month's buyers buy once more, on top of the new sales your growth rate wins. It is a planning approximation, not a full retention model; if your business runs on subscriptions, the Recurring Revenue (MRR) calculator models members, churn, and signups properly.
What do I do with the projection?
Feed it forward and test it backward. Forward: put the monthly revenue line into the Cash Flow Forecast calculator to see if the cash survives the year, and use the Startup Budget calculator if you have not funded the launch yet. Backward: compare month 1 of the projection against your first real month, then adjust the growth rate to what actually happened. A projection you never reconcile is just decoration.
