Revenue growth guidance
See both the dollar change and the percentage change
Growth analysis is clearer when you show the absolute revenue change alongside the percentage. This calculator also calls out the special case where the previous period is zero.
Absolute change
Current revenue minus previous revenue, shown in currency.
Growth rate
The change divided by previous revenue, expressed as a percentage.
Declines are visible
A lower current value produces a negative change and decrease status.
Zero-base limitation
A conventional percentage cannot be calculated when the previous period is zero.
How to use this calculator

Absolute growth versus percentage growth
Absolute growth tells you how many currency units changed. Percentage growth puts that change in relation to the previous period, which helps compare periods of different size.
Positive and negative growth
If current revenue is higher, the calculator shows an increase and positive change. If it is lower, it shows a decrease and negative growth rate.
Why the zero base needs context
When previous revenue is zero and current revenue is positive, the conventional percentage formula has a zero denominator. The absolute change remains meaningful, but the percentage should be described as not calculable from that base.
Example: 25% growth
Previous revenue: $100,000 Current revenue: $125,000 Revenue change: +$25,000 Growth rate: +25% Status: Increase
Common mistakes to avoid
- Comparing periods of unequal length.
- Mixing gross and net revenue definitions.
- Using percentage growth without showing the dollar change.
- Showing Infinity when the previous period is zero.
