One of the most common comments we get here is “how does xxx formula works?” Even though there is vast documentation on excel formulas including the built-in help in MS Office, often it is difficult for us to learn a formula quickly and use it in a snap. So to help new users of excel learn the most frequent formulas I have built an excel formula helper page.
The page currently lists about 50 most commonly used excel formulas along with 1 index card for each to explain,
- what the formula does
- what is its syntax
- 2 examples to understand how it works
see an example:
The good thing about these index cards is, they use simple day to day English to explain the formulas, so I am guessing they are a great way for new users to learn and use the formulas.
I have tried to keep the page simple so that anyone can come and learn a few formulas quickly. Play around with it and let me know if this is useful (of if something is funny / broken)
Here is the link: excel formula helper – 50 day to day formulas explained in plain English

@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.
