How the formula works
Revenue in month n = price times units, where units grow every month. Units in month n equal starting units times (1 + growth) raised to the power of n minus 1. Small monthly growth rates compound into large differences over a year: 5 percent monthly is about 80 percent annual.
Worked example
A course sells at Rs. 2,500 with 80 sales in month one growing 5 percent monthly. Month one brings Rs. 200,000; by month twelve volume reaches about 136 sales and the year totals roughly Rs. 3.18 million, far more than twelve flat months would suggest.
What affects the result
Projected revenue hinges on price, how many units you can actually sell, and whether growth is sustainable. Growth compounds, so a 2 percent difference in the monthly rate can more than double a twelve-month projection at the extremes. Watch three realities: a market ceiling that caps demand, price changes that shift revenue without customer growth, and churn, which trims recurring revenue where subscription accounts are involved.
Common mistakes
- Applying growth forever without a market ceiling.
- Confusing revenue growth with customer growth when prices also change.
- Assuming linear growth when your plan says percentage growth.
- Forgetting refunds and discounts, which reduce realized revenue below the headline.
Frequently asked questions
Should I use optimistic or realistic growth?
Model both. The full app lets you save conservative, expected and aggressive scenarios side by side so the range becomes part of the decision.
How do I include seasonal spikes?
Use the custom monthly schedule in the full app, which accepts a different growth value for each month.
Does this account for churn?
No, this projects gross volume. For subscription businesses use the SaaS calculator which nets churn against new customers.
How do you calculate projected revenue?
Projected revenue in a given month is price multiplied by expected units. With steady monthly growth g, units in month n equal starting units times (1 + g) to the power of (n − 1). Total twelve-month revenue is the sum of the twelve monthly figures.
