Quarter Sum Formulas Add-in – Excel Campus

A solution for quickly creating Excel SUM formulas to sum monthly data into quarters and full year totals using a free add-in. Creating quarterly sum formulas is typically a time consuming process because you can not copy/drag the formulas across to produce totals for Q2 to Q4.

This post provides a solution for quickly creating formulas to sum monthly data into quarters and full year totals using a free add-in.

The Problem

When using the SUM function to sum monthly data into quarterly totals, you can NOT create the formula for the 1st quarter and then copy/drag the formula to the right.

The cell references will only move one column to the right instead of three columns.  If we copy the formula above for Q1 to the right, the resulting formula will give us the total for Feb-Apr.  The correct formula should be a total for Apr-Jun.

The Solution

The Quarter Formulas Add-in creates the correct formulas for the quarters and full year in just a few clicks.  And it’s FREE!

Report Structure Requirements

The Quarter Formulas add-in requires all the month data be in 12 consecutive columns.  The four quarter and year total formulas will be created in five consecutive columns.  You will choose the starting cell (Q1) that the formulas will be created in.  The created formulas do NOT have to be next to the monthly data.

Creating the Formulas

  1. Click the Quarter Formulas Button.
  2. Select the 1st Quarter cell where you want the formulas to be created and click OK.
    – Formulas for Q2-Q4 and Full Year sum will be created to the right of this cell.
    – The selection defaults to the active (selected) cell in the worksheet.  Selecting the Q1 cell prior to clicking the Quarter Formulas button will save you a step.
  3. Select the cell that contains month 1 data and click OK.
    – This is the 1st month in the 1st quarter (January if you are on a calendar year).
    – The selection defaults to 12 cells to the left of the Q1 cell selected in the previous step.  If the quarterly total cells are directly to the right of the monthly data then you will not have to select the month 1 cell.  This will save you another step.
  4. The SUM formulas will be created in the Q1 cell and the four cells to the right of it.
    – Copy the formulas down to fill all the rows in your report.
