HR managers & department heads always ask, “So what is the vacation pattern of our employees? What is our average absent rate?”
Today lets tackle that question and learn how to create a dashboard to monitor employee vacations.
What do HR Managers need? (end user needs)
There are 2 aspects tracking vacations.
- Data entry for vacations taken by employees
- Status dashboard to summarize vacation data
Based on my interaction with few HR managers, the below questions are asked most often when it comes to vacation tracking:
- What is the absent rate of our employees (in any year or latest 3 month period)
- What are the vacation patterns for individual employees (or teams)
- On which dates most employees are absent?
- Who is taking most (or least) vacation days?

Constructing Employee Vacation Dashboard
The construction process can be broken in to 3 steps:
- Vacation tracker for entering dates & types of vacations.
- Calculation engine
- Dashboard design & formatting
Step 1: Creating a tracker for vacations
The best way to create a tracker is to use Excel tables. Set up one with 4 columns – Employee name, vacation type, start date & end date, like below:
By using tables, we can continue to add more vacation data (or remove older data) and all our formulas continue to work seamlessly.
Additional tables required…
Apart from the main vacations table, we need below tables:
- Employees table – to keep the names of employees
- Vacation types table – to keep the type of vacations
- Holidays table – with official holiday dates
Step 2: Calculation engine
There are 3 portions in our dashboard and each of them requires certain calculations.
- Date logic
- Employee view
- Calendar view
For all the views, the main driver is latest date, which is the maximum value of end date column in vacations table (=MAX(Vacations[End Date]))
Tip: Use Max to find latest date
Although the calculations are not very complex, explaining each of them can be very tedious. So let me summarize them with a diagram.
Important formulas used in the calculations:
The key formulas & ideas used are,
- Range lookup formula
- SUMIFS formula
- Calendar formulas
- EDATE, EOMONTH, WEEKDAY, NETWORKDAYS Formulas
- The lovely INDEX formula
Step 3: Dashboard design & formatting
This dashboard is an excellent example of synthesis – combination of multiple Excel features to create something very simple and easy to use.
Excel features & ideas used:
There are many Excel features & ideas used in this dashboard. First take a look at the illustration below.
- Combo box form control to select an employee to highlight their vacations
- Conditional formatting & cell grid to show vacations in a gantt chart like view.
- Highlighting selected employee’s vacations again using conditional formatting.
- Calendar view created by picture links
- Heat map of number of people away on each date using conditional formatting (similar example).
- Header section with references to calculations & cell formatting.
- Hyperlink on a rounded rectangle shape to link to tracker sheet.
Formatting the dashboard:
The basic layout of dashboard is just 3 boxes – a big summary box on top, a large employee view box (70%) and a small calendar view box (30%).
The fonts are Calibri & Cambria default fonts in Excel 2007 or above.
I used variations of Tan color in most areas of dashboard (headers, box backgrounds, buttons etc.) and shades of pink, blue, green & gray for marking the vacations. Orange is used to highlight selected employee’s vacations.
Although there is a lot of data, I designed this dashboard with minimal clutter. It is very easy to use (there is only one input control).

How do you like this dashboard?
I have thoroughly enjoyed the process of building this dashboard. I especially loved how picture links, conditional formatting heat maps (color scales) & simple calendar logic all have blended in to create a stunning calendar view.
What about you? Do you like this dashboard? How would you have designed it? Go ahead and share your feedback, ideas & suggestions for improvements in comments. I am eager to learn from you.

Hi Chandoo
As one of your students I have followed your detailed example through with great success. However, Excel is acting in an unexpected way and I wonder if you could take a look?
http://cid-95d070c79aef808e.office.live.com/self.aspx/.Public/Gantt%20Box%20Chart.xlsm
On my version, I have to type 40239 (Which equates to 2 Mar 2010) to get the chart to display 31 May 2010 (which should be 40329)!!??
Have I done something wrong or is Excel acting up?
Thx
Oli
PS Your example file in 2007 displays correctly.
Hi,
I like this idea a lot, but I agree the name is a little drab.
As an American I may just be seeing things, but to me the combination of lines and bars on your chart looks like a bunch of cricket bats.
Maybe you could work that into a catchier name. 🙂
Cheers!
Here is some code I use to keep the axis synched.
It may be useful to some of your readers
It is based on a comment I saw on Daily Dose of Excel.
Function SynchGanttAxis(Cname, lower, upper)
'Sets the X min and X max for Category axis
Application.Volatile
On Error Resume Next
'
'Top Horizontal Axis
With ActiveSheet.Shapes(Cname).Chart.Axes(xlCategory, 1)
.MinimumScale = lower
.MaximumScale = upper
End With
'Bottom Horizontal Axis
With ActiveSheet.Shapes(Cname).Chart.Axes(xlValue, 2)
.MinimumScale = lower
.MaximumScale = upper
End With
End Function
Function SynchVerticalAxis(Cname, lower, upper)
Application.Volatile
On Error Resume Next
' Excel 2007 only
'Right hand vertical axis
With ActiveSheet.Shapes(Cname).Chart.Axes(xlValue, 1)
.MinimumScale = 0
.MaximumScale = upper
End With
End Function
@Oli.. Can you check your file again.. I see 40329...
@Dave: Even I saw things.. the bars actually looked like lollipops. How about calling this lollipop chart - now that would be yummy and goes along the tradition of naming charts after eatables (bar, pie, donut...)
@Bob: Superb stuff... thanks for sharing 🙂
Hi Chandoo
This looks really good and I think it can also be applied to show project phases / milestones.
Question: Thinking further could this be amended to display a project lifecycle (Idea through to Implementation say 7 phases) on one bar / row? Just imagine 20 projects within a programme all on one chart one bar each showing their respective lifecycle stages i.e. on one page.
Idea: As the Gantt Box Chart this is quite intensive to set up re formatting etc how about the added extra of once you have completed this to "Save as template" i.e. saves the formatting and layout of the chart as a template so you can apply to future charts. Simple to do and will save the time formatting etc again and again and again.
Therefore tip: Click on your chart demo and then click on Save As template icon (2007) - edit file name and click on save. Ready to use / apply via Templates in Change Chart Type window.
Thanks and be very interested if the lifecycle question can be resolved
Mike
How embarrassing.
I was obviously suffering from numerical dyslexia. I was one of those days.
@Mike H: You can easily make this chart to work like a generic project lifecycle plan chart. All you have to do is,
1. in a separate sheet define the steps of lifecycle and various dates in a table (with 5 columns for each of the projects you have).
2. now use a control cell to input the project name you want to show in the chart
3. based on the input, use OFFSET Formulas to get the correct data
4. Rest is same as the tutorial above

Your solution is really smart but in the en Excel isn't meant to do stuff like this. I, as a former PM, always thought is was frustrating that you had to do stuff like this for something simple like a Gantt chart. So I built Tom's Planner. And would like to plug it here. I think it really solves the problem you are trying to solve in the most efficient way. Check out http://www.tomsplanner.com for a free account or play around with the demo.
Hi there,
Chandoo - this is really a very nice and helpfull chart - I adopted it, so I can report a forecast or the delay of a certain task (coming from my role as an auditor for projects).
One topic I´m currently struggeling with: I do have a project lasting for lets say 12 month. For a management reporting, I want to have kind of snapshot, lets say one month back and 2 month in the future. I tried with the offset formula, but failed. Any idea?
Thx
Lopi

Hi Chandoo - fantastic xls. One thing I can't figure out how to do is adjust the alignment of the vertical axis. I would like to left align so that I could indent to represent sub tasks. Can that be done? Or is there a better way?
I've been trying to work out if there's a way to show weekends on the graph. The closest thing I've got is to add them on a secondary axis, but then I haven't been able to keep both axis lined up together! Any ideas?
Following on from this - is it possible to show things like holidays?
