Sales Percentage Increase
—
A positive number is sales growth; a negative number means the new sales are lower than the previous period's.
What is a sales percentage increase calculator?
A sales percentage increase calculator measures how much sales have grown between two periods, expressed as a percentage of the previous period's sales. It answers the question: by what percentage did sales go up? It is used for month-over-month, quarter-over-quarter, and year-over-year sales reviews.
The formula is ((new sales − previous sales) / previous sales) × 100. The increase is divided by the previous sales, so the result is always relative to your earlier period. The sales percentage increase calculator applies this automatically and returns both the percentage and the dollar growth.
Tracking the sales percentage increase matters because a flat dollar gain hides the real trend. A 2,500-dollar increase means very different things on 10,000-dollar sales and 100,000-dollar sales. Expressing the change as a percentage lets you compare momentum across periods, products, and channels.
