What this calculator does
Sales growth compares current sales with a previous comparable period. The calculation is simple, but the comparison only becomes meaningful when both periods use the same revenue definition and cover equivalent lengths of time.
What to know before you use the result
- Compare like-for-like periods whenever seasonality matters.
- Use the same currency and revenue definition in both values.
- Percentage growth can look dramatic when the starting value is very small.
Common mistakes to avoid
- Comparing one month with an entire quarter.
- Mixing gross sales with net sales.
- Ignoring seasonality, acquisitions or one-time events when interpreting growth.
