Lets test your Excel skills. Can you write a formula to check few cells are equal?
Your homework:
- Let us say you have four values in cells A1, A2, A3, A4
- Write a formula to check if all 4 cells have same value (ie A1=A2=A3=A4)
- Your output can be TRUE/FALSE or 1/0 to indicate a match (or mis-match)
Bonus question 1:
How would you write a formula if your values are in range A1:An
Bonus question 2:
What formula would work well if the cells contain non-numeric values (text, logical etc.)
Obvious answer:
The easiest and obvious answer is to test if all them are equal. The formula is,
=AND(A1=A2,A1=A3,A1=A4)
(select the above blank line to see answer)
But can you come up with some other options to test the equality?

@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.
