How to calculate your revenue growth rate
Revenue growth rate shows how fast your revenue (faturamento) is rising or falling between two periods. Here is the formula, two worked examples and the mistakes to avoid.
The revenue growth formula
Revenue growth rate (%) = (revenue this period − revenue last period) ÷ revenue last period × 100
A positive result means revenue grew. A negative result means it fell.
Worked examples in reais
Two examples
| Comparison | Previous period | Current period | Growth rate |
|---|---|---|---|
| Month on month | BRL 200,000 | BRL 220,000 | 10% |
| Year on year | BRL 2,500,000 | BRL 2,250,000 | −10% |
In the first example, revenue rose by R$20,000 on a base of R$200,000. That is a growth rate of 10%. In the second, revenue fell by R$250,000 on a base of R$2,500,000. That is a growth rate of −10%.
Common mistakes
- Comparing unequal periods. A 31-day month against a 28-day February can distort monthly growth.
- Ignoring seasonality. For seasonal businesses, compare a period with the same period a year earlier. For example, compare December with the previous December.
- Mixing one-off revenue with recurring revenue. A single large order can make growth look stronger than it is.
Frequently asked questions
What is the difference between month-on-month and year-on-year growth?
Month-on-month compares one month with the month before it. Year-on-year (or YoY) compares a period with the same period a year earlier. This removes most seasonal effects, such as Christmas or Black Friday.
Can the revenue growth rate be negative?
Yes. A negative growth rate means revenue fell between the two periods.
