Mustache and Excel?!? Sounds as unlikely as 3D pie charts & Peltier. But I have a story to tell. So grab a cup of coffee and follow me.
Few months ago, I chanced up on a highly entertaining blog on money, retirement & living a kick-ass life. Reading Mr. Money Mustache is much like I am talking to myself. Almost all of his money philosophies, values & hacks are similar to what we practice at Chandoo household. Immediately I got hooked. In a span of 2 weeks, I read more than 100 articles, often making Jo suspicious what I was doing so much on her iPad.
At this point, you must be thinking -“Dude, what has all this got to do with Excel?!?”
And I am coming to that. One of the ideas Mr. Money Mustache preaches is small regular expenses can add up to massive amounts of cash (or ‘stash as he calls it) over several years. Now that we do not have a full time job, live in a small town & crave little, we barely spend anything. But I can relate to his idea. For example, if you spend a few dollars everyday at local coffee shop, over 10 years, this could add up to more than $10,000. Money that could be used for other worthy goals like early retirement or starting your dream company. Mind you, I have nothing against coffee. In fact, I brew two cups of lovely cappuccino every morning so that Jo and I can savor it before the kids wake up and start the hulk_in_the_house program. It is another thing that the last time I bought a cup of coffee is when I was in Australia in June. But the important idea here is that regular expenses should be carefully monitored and pruned.
“What?!? You are talking about coffee and kids. Where is Excel?!?”
Ok, I am done with the build up. So one fine morning, I emailed Mr. Money Mustache, introduced myself as somewhat spreadsheet skilled and shared a file I created with him, using which community at his site can see how regular expense cuts can impact their savings. He was kind enough to publish it here.
A growing mustache chart
Well, I am not sure what else to call it. So lets stick with growing mustache chart. Here is how it works:
- You enter a sufficiently large number ie the money you want to accumulate to retire or do something equally awesome.
- You also enter your regular expenses (daily, weekly, monthly, annual or one time) and amounts.
- Then it magically calculates how much money you would save by cutting them.
- All this is shown in a dynamic chart that depicts your target and actual as mustaches
See this demo:
This is so cool, how is it made?
There are 4 steps to our growing mustache Excel chart.
1. Calculating future value of regular expenses
Question: If you consume $3.50 latte every day for next ten years, how much would you spend?
Answer: Gee! Sounds like a big problem, let me grab a cup of coffee first!
On a more serious note, the future value of these little expenses depends on rate of return as well. That is, instead of gulping down $3.50 in a hurry, if you saved the money the return you get on yearly basis.
For our calculations, we can assume a 7% return. This gives a future value of$18,498.
You can use the formula =FV(7%/365,365*10,3.5) to get this value.
So the multiplication factor is 5,285 (18,498 divided by $3.5)
For our calculations, we can use a simple multiplication factor table so that we can focus on growing mustache than financial mumb0-jumbo.
2. Calculating Totals
Once we know the future values of all such regular expenses, we just need a small table like this that shows the totals:
3. Create a bubble chart
Next, we create a bubble chart with 2 bubbles. 1 for the actual mustache & 1 for target mustache.
4. Convert bubbles to mustaches
Hermione would know a great spell to instantly turn our boring bubbles to mighty mustaches (bulla-mustacium ?). But since we are muggles, lets focus on Excel trickery.
We need the chart on right from our bubbles:
First get a nice handlebar mustache image from web, like this:
- Then, copy the gray color mustache (ctrl+c)
- Next, select outer bubble (target) and press paste (ctrl+v)
- Now, the bubble becomes mustache!
- Repeat the steps for actual bubble too.
That is all!

Do you like the growing mustache chart?
I really liked how this turned out. Simple yet effective. Readers at Mr. Money Mustache site loved it too.
What about you? Did you enjoy this trick. Are you planning to cut any regular expenses after reading this? Please share using comments.

An excellent solution, especially for large data sets.
Another solution without using solver would be to assign the player with the highest score to Team 1, the 2nd to team 2, 3rd to team 3, 4th to team 3, 5th to team 2, 6th to team 1, 7th to team 1 and it continues. This method would end up with a Std Dev of 0.001247219. This works best with a distribution with lower Std Dev for the dataset.
Full Disclosure: this is not my idea, remember reading something a few years ago. Think it may have been Ozgrid
thinking back I now remember why I read about it. About 10 years back I had to distribute around 300 team members into 25-30 odd teams. Used this method based on their performance scores. I used the method I described to do this and the distribution was pretty fair.
Solver would have saved me a ton of time though 🙂
I think the issue with you first Solver approach was that you took the absolute value of the sum of team deviations (which should always be zero except for rounding) instead of the sum of the absolute values (which is a reasonable measure of how unbalanced the teams are).
Here's another simple algorithm you could use: you start from the top (with players sorted from high to low), and at each step allocate the next player to whichever team has the smallest total so far. You can implement it dynamically with some formulas so it will update automatically when the data changes.
If the scores were more widely distributed (so that this might end up with not all teams the same size), you could add a constraint to only pick among the teams which currently have fewest players at each step, or just stop adding to any team when it hits its quota.
When I tried it on the sample, I got the three teams below, with a STDEV of 0.000942809 (i.e. about half of what Solver got to).
Team 1: John, Hugo, Tom, Josh, Eric, Zane, Charles, Andrew
Team 2: Barry, Michael, Kenny, Joe, Xavier, Patrick, Oliver, William
Team 3: Henry, Steven, Ben, Frank, Kyle, Edward, Cameron, Lachlan
Thanks for sharing!
Hi,
I was looking at all the solutions and this is closest to what I intended to do. I am dividing a bunch of players into 3 soccer teams. Players availability is also a factor while deciding the teams.
So the steps the excel needs to do is as follows:
1) In availability column if "yes" go to next
2) Equally divide 'Goalkeepers', 'Strikers', 'Defenders' basis their quality
So the end result gives each 3 teams a balance of players playing at different positions.
Can this be done on Google spreadsheet with only availability as an input from the user and rest calculates by itself.
Sorry for asking such a pointed question, but I have been struggling to find a solution for it for sometime now!
Hi Ishaan,
I am working on a similar problem at the moment, so I am wondering if you ever found a solution and if you are willing to share what you did.
Hi everyone, this is a variation of the famous Knapsack Problem https://en.wikipedia.org/wiki/Knapsack_problem.
I had to use a VBA implementation recently as part of a problem, where we ar trying to allocate teams of an organization into different locations (we are a large company with many different team). The goal was to optimally allocate teams to individual buildings without putting too many teams into one building and not splitting teams apart.
As we had around 400 teams of different sizes, solver couldn't handle it anymore. Luckily there is a Knapsack algorithm implementation in VBA readily available on the internet :).
I also went with a heuristic approach first!
An interesting mathematical solution but what if Eric and Xavier can't stand each other or Patrick is best friends with Steven - the real life problems that effect "even" teams.
@Joe
You can add more criteria like
If Eric and Xavier can't stand each other
=OR(AND(E15=1,E16=1),AND(F15=1,F16=1),AND(G15=1,G16=1))
It must be False
If Patrick is best friends with Steven
=OR(AND(E5=1,E17=1),AND(F5=1,F17=1),AND(G5=1,G17=1))
It must be True
Note that the 2 formulas above are exactly the same
except for the ranges
One must be True = Friends
One must be False = Not Friends
Nice Post!
Just one question What if number of players are not even or equally divisible.
Nice post Hui!
I download your workbook and just try to change in options the Precision Restriction from 10E-6 to 10-8 and the Convergence from 10E-4 to 10E-10. The process take almost the same time, but the results was great.
The standard deviation I got was 0,000471.
Team 1: John, Tom, Kenny, Frank, Eric, Xavier, Edward, Zane
Team 2: Steven, Hugo, Ben, Joe, Josh, Oliver, Cameron, William
Team 3: Barry, Henry, Michael, Kyle, Patrick, Charles, Andrew, Lachlan
Great application of Solver! Thanks for the link!
Great explanation. Well done... However, I tried with 6 teams of 4 players and solver never did finish.
How about vba code for the same data set.
I have 3 column A B C wherein A has text and B has number Wherein C is blank. And in C1 been the header C2 where I want the name to come evenly distributed the number which is in Column B.
My Lastcolumn is 1000.
Sorry if I'm being slow here, but how is 'Team Score' calculated? I've gone through the explanation several times but it seems to just appear.
@Hrmft
This process uses the Solver Excel addin
Solver is effectively taking the model and trying different solutions until it gets a solution that meets all the criteria
Then solver puts the solution into the cell and moves to the next cell
So yes it appears to "just appear"
Hi ! Thank you so much ! Works great 🙂
I cannot get the fourth Equation to work in my excel spreadsheet
You have =($E$2:$G$25=0)+($E$2:$G$25=1)=1 as a SUMIF solution, I have, =($F$2:$H$13=0)+($F$2:$H$13=1)=1 as my solution but it does not work. The only thing I changed is the ranges. Any suggestions?
Thank you.
Jim
