How to Calculate QoQ

The calculation of QoQ is straightforward, involving comparing the current quarter's value to the previous quarter's value to determine the change rate.Formula:

  • QoQ Growth Rate = (Current Quarter's Value - Previous Quarter's Value) / Previous Quarter's Value × 100

Example:

  • Previous Quarter's Sales: $200,000

  • Current Quarter's Sales: $250,000

  • QoQ Growth Rate = (250,000 - 200,000) / 200,000 × 100 = 25%

In this example, the sales increased by 25% compared to the previous quarter.
