Sales change
Shows current sales less previous sales.
Enter a previous-period sales amount and current-period sales amount to calculate the change and growth rate.
Sales change = current sales - previous sales. Growth rate = (current sales / previous sales - 1) x 100.
Shows current sales less previous sales.
Expresses the change relative to previous sales.
Shows how many times current sales represent prior sales.
Sales growth compares a current period with a previous period on the same basis. Subtract prior sales from current sales to find the absolute change, then divide the change by prior sales for the percentage growth rate. The ratio expresses current sales relative to prior sales as a multiple.
Comparisons are most useful when both periods cover equivalent dates, channels, currencies, product scope, accounting treatment, and returns policy. Seasonality, acquisitions, discontinued products, promotions, and changes in reporting can create a growth number that is accurate mathematically but misleading operationally.
When prior sales are zero, a percentage growth rate is undefined because there is no nonzero base. In that case, report the absolute increase and explain the context. This tool does not forecast future sales or measure profitability.
| Input | What it means | Planning note |
|---|---|---|
| Previous sales | Sales in the comparison baseline period | Use a like-for-like period and accounting basis. |
| Current sales | Sales in the newer comparison period | Use the same currency and recognition method. |
| Sales change | Absolute movement between the two entries | A negative amount indicates a decline. |
| Growth rate | Change divided by previous sales | Undefined when previous sales are zero. |
Compare this month with the same basis last month.

It depends on the market, maturity, seasonality, margins, capacity, and comparison base.
