ABC analysis is a popular technique to understand and categorize inventories. Imagine you are handling inventory at a plant that manufactures high-end super expensive cars. Each car requires several parts (4,693 to be exact) to assemble. Some of these parts are very costly (say few thousand dollars per part), while others are cheap (50 cents per part). So how do you make sure that your inventory tracking efforts are optimized so that you waste less time on 50 cent parts & spend more time on costly ones?
This is where ABC analysis helps.
We group the parts in to 3 classes.
- Class A: High cost items. Very tight control & tracking.
- Class B: Medium cost items. Tight control & moderate tracking.
- Class C: Low cost items. No or little control & tracking.
Given a list of items (part numbers, unit costs & number of units needed for assembly), how do we automatically figure which class each item belongs to?
And how do we generate above ABC analysis chart from it?Continue »
My mom will be very unhappy with this post. She always told me to focus on one thing at a time. But in this post we are talking about 3 things, not one. Sorry mom.
1. Thank you
I want to thank you for visiting chandoo.org & supporting us.
As I am about to leave to USA for attending Excelapalooza conference, I couldn’t help but be amazed at how much you have given me & my family. Almost 4.5 years ago, when I left my plush corporate job to work full time on Chandoo.org, I had no clue how the future will unfold. Today my heart is full of happiness, my family is secure, my site has grown by heaps and our community (especially you) is awesome.
Without your enthusiasm to learn and keen desire to become awesome, I would not have a job (of running this website). You inspire me to learn new things everyday so that I can share them with you.
Thank you for all the visits, clicks, comments, emails, tweets, likes, signups, purchases & love.
Thank you.Continue »
We all know about the MAX formula. But do you know about 3D Max?
Sounds intriguing? Read on.
Lets say you are the sales analyst at ACME Inc. Your job involves drinking copious amounts of coffee, creating awesome reports & helping ACME Inc. beat competition.

Your data is not in one sheet. It is in multiple sheets, one per month.Continue »
Time for another quick Excel tip.
Lets say the park near your house rents tennis courts by hour. And they charge $10 per hour. At the end of an intense tennis playing week, Linda, the tennis court manager called you up and said you need to pay $78 as rent for that week.
How many hours did you play?
Of course 78/10 = 7.8 hours.
But we all know that 7.8 hours makes no sense.
We also know that 7.8 hours is really 7 hours 48 minutes.
So how to convert 7.8 hrs to 7:48 ?Continue »

Ok people. Let me tell you that this post is almost not about Excel. It is about how one Excel blogger’s (yours truly) dream of long distance cycling came true. So sit back, grab your favorite drink and read between sips.
So what is this all about?
Last Sunday (27th July) & Monday (28th), I finished my first ever 200KM bicycle ride. I rode for a little more than 12 hours, burned 5,179 calories & rode 206 kilometers.
It is definitely one of the most memorable, tiresome & uplifting experiences in my life. So naturally, I want to share the story with you.Continue »
Today lets learn about Excel CHOOSE() function.
CHOOSE eh? What does it do?
To understand CHOOSE() and appreciate its uses, lets invent an imaginary boos-subordinate pair.

About a month and half ago, we held our annual dashboard contest. This time the theme is to visualize state to state migration in USA. You can find the contest data-set & details here.
We received 49 outstanding entries for this. Most of the entries are truly inspiring. They are loaded with powerful analysis, stunning visualizations, amazing display of Excel skill and design finesse. It took me almost 2 weeks to process the results and present them here.

Imagine you are the head of Accounts Receivable department at a large company. Drab, I know, But humor me and imagine.
Now, every month you get a transaction report.
And you want to know which numbers are matching up.
i.e, if your company gave Vendor-0002 $872.34 on 1st of April, 2014 and your received below payments from them subsequently,
- $427.77 on 1st April
- $152.88 on 2nd April
- $291.69 on 2nd April
Then you consider the account matched since the total received is same as total payable.(427.77 + 152.88 + 291.69 = 872.34).Continue »
