A while ago, we published a new year resolution template. This was a hit with our readers with thousands of you downloading it. During last week, Peppe, one of our readers from Italy, took this template and made it even more awesome.
The original template had tasks and completion check marks. As you finish each task, you can see overall progress too.
Peppe added priorities to this. With his new version, progress is measured based on how much priority we assigned that particular task. Pretty neat eh?!?
Personal Todo list with Priorities – Demo
First take a look at Peppe’s todo list.
How is this made?
Using lots of Excel goodness of course. The basic components of this todo list are,
- Check boxes – to mark each activity as done (or not done)
- Data validation – to assign priority (1 to 5) to each activity
- Conditional Formatting – to highlight a row when the activity is marked as done
- Thermo-meter chart – to show the progress as you mark each activity done
- Formulas – to calculate % done based on how many activities are done & their priorities.
Since first 4 items are already explained on Chandoo.org, let me focus on the formula part.
Calculating % completion based on priorities:
To understand this problem, lets imagine, we have 5 tasks & priorities like below:
Step 1: Calculating weights
First step is to calculate how much weight each task should get. This is a simple job of inverting priority values (1/priority value). We will get this.
Step 2: Calculate weights to 100%
Next, we adjust the weights so that their total is 100%. To do this, we just divide a task’s weight by total of all task weights.
Step 3: Calculate % done only if a task is marked as done
Now, we just use TRUE / FALSE values generated by the check boxes to calculate % done. For this, we just need to multiply 100% weights with TRUE or FALSE values.
The total of this column gives us how much % of all tasks are done.
Note on weights for priorities
In this approach, we are assuming that doing one priority 1 task gives same output (%done) as doing two priority 2 tasks, three priority 3 tasks etc.
That means the weight enjoyed by priority 1 task is twice that of priority 2 task.
Some other possibilities are,
- Priority 1 is 1, 2 is 0.8, 3 is 0.6…
- A mapping table telling us how much each priority weighs

Thank you Peppe
I find this template quite simple, yet powerful. It shows how much we can do with Excel by using a little creativity, simple features (conditional formatting, form controls etc.) and a some motivation.
Peppe, Thank you so much for sharing this with us.
If you enjoyed this todo list template, go ahead and say thanks to Peppe.

Hi Purna..
Again a great tip.. Its a great way to convert Fractional Time..
By the way.. Excel has two great and rarely used formula..
=DOLLARFR(7.8,60) and =DOLLARDE(7.48,60)
basically US Account person uses those to convert some currency denomination.. and we can use it to convert Year(i.e 3.11 Year = 3 year 11 month) and Week(6.5 week = 6 week 5 days), in the same manner...
This doesn't work for me. When applying the custom format of [h]:mm to 7.8 I get 187:12
Any ideas why?
@Jason
7.8 in Excel talk means 7.8 days
=7.8*24
=187.2 Hrs
=187 Hrs 12 Mins
If you follow Chandoo's instructions you will see that he divides the 7.8 by 24 to get it to a fraction of a day
Simple, assuming the fractional time is in cell A1,
Use below steps to convert it to hours & minutes:
1. In the target cell, write =A1/24
2. Select the target cell and press CTRL+1 to format it (you can also right click and select format cells)
3. Select Custom from “Number” tab and enter the code [h]:mm
4. Done!
Hi, sorry to point this out but Column C Header is misspelt 'Hours Palyed'
good one
So how do I go the other way and get hours and minutes to fractional time?
If you have 7.5 in cell A1,
- Use int(A1) to get the hours.
- Use mod(A1,1)*60 to get minutes.
If you have 7:30 (formatted as time) in A1
- Use hours(a1) to get hours
- Use minutes(a1) to get minutes.
I had the same issue. You can solve it by changing the format as described above:
Right click cell > Format Cells > (In Number tab) > Custom > Then enter the code [h]:mm
([hh]:mm and [hhh]:mm are nice too if you want to show leading zeros)
Thanks guys, these are the tips I'm looking for.
...dividing the number of minutes elapsed by the percent change is my task - "int" is the key this time
It doesnt work for greater than 24 hours
It returns 1:30 for 25.5 hours. It should have returned 25:30
Ideally I would right function as
=QUOTIENT(A1,1)&":"&MOD(A1,1)*60
Sorry, replied to wrong comment....

Clever use of MOD here to extract the decimal part of a number. Divide a number containing a decimal by 1 and return the remainder. Humm. Very clever.
Thanks very much, extremely useful !
