How to Use the Quarterly Sales Growth Calculator
To know whether this quarter's revenue is actually good, you need two reference points: quarter-over-quarter (QoQ), comparing against the immediately prior quarter, and year-over-year (YoY), comparing against the same quarter last year. Enter this quarter's, last quarter's, and last year's sales to see both growth rates at once.
QoQ (%) = (this quarter's sales โ last quarter's sales) รท last quarter's sales ร 100, and YoY (%) = (this quarter's sales โ same quarter last year) รท same quarter last year ร 100. Looking at QoQ alone can mistake seasonal peaks or slow periods for real growth, so checking both metrics together gives a more accurate read on the underlying trend.
