When you are a “work from home” dad, you can see a lot of patterns. Here is one.
My kids come home from school by noon (they are too young for full day school). Right after lunch they watch their favorite cartoon program, Team Umizoomi, in which few fictional characters go about solving problems in the Umi city using maths. Milli, one of the characters is an expert with patterns. She solves problems by identifying patterns and unleashing pattern power.
Here is a fun example of the pattern power. (It has Chef Gordan Ramsey too, which is sweet)

Team Umizoomi & Excel Fill – How do they link up?
Here is how they link up.
Imagine you have a workbook where you need to follow a pattern, like one of these:

You too can unleash the pattern power. What more… you needn’t break in to a song sequence every-time you unleash the power.
How to use Excel’s pattern fill?
Here is an example. Let’s say you want 2 different formulas & 1 blank cells in a sequence.
- Write the first formula in cell 1
- Second formula in cell 2
- Leave the 3rd cell blank
- Select all 3 cells
- Drag to fill
See the screencast aside to understand this concept.
Bonus tip: You can use this technique horizontally too.
Where to use this pattern power?
Here are few uses for pattern fills:
- Dashboards & reports where you need to show some information but space it with blanks for readability
- Apply different formatting to different rows / columns
- Set conditional formatting only to every nth cell
- Format (or write formulas for) weekdays & weekends differently
I use pattern power often when designing dashboards or complex reports.
What about you?
Do you use pattern power? Tell us in the comments where you would use them.
I must go now, I hear the umi alarm. Looks like the kids are back from school.

Wow! What a Powerful article!
Hello Chandoo Sir

thanks

@Ravi... this is a Power BI workbook. You need Power BI Desktop to view it. See the below tutorial to understand what Power BI is:

As always, superb article Chandoo... 🙂
Just one minor issue:
While following your steps and replicating this calculator in PowerBI, I found that the Growth Pct Parameters should be set as "Decimal number" not "Whole Number"
OR
we have to make corresponding adjustments in the Forecast formulas (i.e. divide by 100) to get accurate results.
You are right. I used whole number but modified the auto created harvester measure with /100 at end. Sorry I did not mention it in the tutorial.
Instead of
[Growth Pct 1 Value]/12
the monthly rate has to be
(1+[Growth Pct 1 Value])^(1/12)-1
It's a slight difference but in 30 years the future value will be $100k less.
