How to Calculate Quarterly Growth Rate in Excel

Calculating the quarterly growth rate is essential for financial analysts, marketers, and business owners to track performance momentum. While the calculator above provides instant results, performing these calculations in Excel allows for bulk data processing and automated reporting.

Method 1: Simple Quarter-over-Quarter (QoQ) Growth

If you are comparing two consecutive quarters (e.g., Q1 Revenue vs. Q2 Revenue), the formula measures the percentage change directly.

The Math: (Current Quarter – Previous Quarter) / Previous Quarter

Excel Formula:

=(C2 - B2) / B2

Where cell B2 contains the Previous Quarter's value and C2 contains the Current Quarter's value. Format the result cell as a Percentage.

Method 2: Compounded Quarterly Growth Rate (CQGR)

If you want to calculate the average growth rate over a longer period (e.g., Q1 2023 to Q1 2025), you cannot simply average the percentages. You must use the Compound Growth Rate formula.

The Math: (End Value / Start Value)^(1 / n) – 1

Excel Formula:

=(End_Value_Cell / Start_Value_Cell)^(1 / Number_of_Quarters) - 1

For example, if A2 is your starting value (100) and E2 is your ending value (150) over 4 quarters:

=(E2/A2)^(1/4)-1

Method 3: Using the Excel RRI Function

Excel has a built-in function specifically for calculating the equivalent interest rate for the growth of an investment, which works perfectly for compound growth rates.

Syntax: =RRI(nper, pv, fv)

  • nper: Number of periods (Quarters)
  • pv: Present Value (Start Value)
  • fv: Future Value (End Value)
=RRI(4, A2, E2)

Understanding the Results

Positive Growth: Indicates an increase in the metric (revenue, users, etc.). A stable positive quarterly growth rate implies healthy scaling.

Negative Growth: Indicates a contraction. Seasonal businesses often see negative quarterly growth in off-seasons (e.g., retail in Q1 vs Q4).

Zero Growth: The metric has remained stagnant. This is calculated as 0%.

Note on #DIV/0! Errors in Excel: If your Starting Value is 0, Excel will return a division error because mathematical growth from zero is undefined (infinite). Ensure your starting denominator is never zero.
