MS Excel formulas every professional must know

Almost all professionals have used MS Excel in some form or the other. Most haven’t taken up any formal Ms Excel tutorial. Through self-study, they’ve picked up basic excel formulas and features to help them with their day-to-day tasks.

However, most don’t realise the power that’s available at their finger tips if they’d take the pains to understand some special excel formulas.

Apart from all the fantastic theoretical concepts that MBA students learn in a classroom, most realise that the lowly MS Excel formulas they’ve ignored so far can be their best friends as they head out into their post MBA jobs. In fact, many quant focussed MBA jobs (like consulting) specifically need advanced excel skills.

In my post-MBA job, I spent 5 years managing Mergers & Acquisitions (M&A) transactions. In almost all the M&A valuation modelling that I did (some deals valued at hundreds of millions of dollars), there was a heavy dependency on these seemingly simple and mundane, yet powerful formulas.

But you don’t have to head to business school to learn them. We’ve picked out the 10 best MBA Excel formulas that can save you and your company valuable hours and money – by automating routine tasks, improving efficiency and doing complex calculations that your brain would’ve struggled with.

MS Excel formulas for every MBA & professional

As this is an introductory post, instead of trying to replicate the structure and format of an MS Excel Tutorial, we’ll only touch upon the concepts. If any of these formulas catches your fancy, you can always follow up to learn more.

What are MS Excel formulas?

If this sounds too basic, skip to the next section.

Let’s consider a simple example to understand what excel formulas are and what they can do. As you’d know, excel worksheets are organised as 2-dimensional grids, with columns (named as ‘A’, ‘B’, ‘C’ etc) and rows (labelled as ‘1’, ‘2’, ‘3’ etc). You can specific each ‘cell’ with its reference e.g. ‘A1’, ‘A2’, ‘B1’, ‘B2’

If you want to add the values of 5 cells in Column A, you could use the formula:

= A1 + A2 + A3 + A4 + A5

What if you had a hundred values to add, or a thousand. It’ll get pretty tedious to mention each cell name in the formula. This is where excel formulas come into picture.

These simple concepts can be used in complex and powerful ways to deal with a numeric and textual data.

Technically, these are MS excel functions. But most professionals don’t bother about it and refer to them as Excel formulas. So that’s what we’ve done here. Your knowledge and the output you can produce with them is more important than the technical names.

MS Excel Formulas for Numeric / Mathematical Operations

When God Gates created MS Office, he made MS Excel the king of the numeric world (while MS Word got language). So it’s only fair that you start building your MS Excel skills with the basic numeric operations.

In the example that we talked about earlier (where you needed to add 5 numbers), instead of the earlier approach of adding 5 cell references, you could simply use a function:

=SUM (A1:A5)

If you want to add the values in the first 100 cells in Column A, instead of the long-winded approach (=A1+A2+…..+A99+A100), all you need to do is change the formula to:

= SUM (A1:A100)

While we are on the topic, what goes inside the brackets are called ‘arguments’. But for this post, to avoid getting it mixed with the literal meaning of that word, we’ll call them as ‘parameters’.

In addition to SUM(), the other basic mathemetical functions you could check out are: AVERAGE(), MIN(), MAX(), COUNT(), SUMPRODUCT()

MS Excel Formulas for String Operations

In the MS Excel world, ‘String’ refers to ‘Text’ (as opposed to Numbers). There’s a bunch of excel formulas that allow you to manipulate, edit & build strings.

Here’s a list of basic excel formulas to manage strings.
LEN(), TRIM(), LEFT(), RIGHT(), FIND(), MID(), REPLACE(), SUBSTITUTE(), CONCATENATE()

Each of these MS excel functions needs one or more parameters to be specified.

LEN (“MBA Crystal Ball”) will display 16. That’s the number of characters (including spaces) in the string.

Similarly, LEFT (“MBA Crystal Ball”, 3) will display the first 3 characters (‘MBA’) of the bigger string.

MID(“MBA Crystal Ball”, 5, 7) starts from position 5 and displays the 7 subsequent characters i.e. ‘Crystal’.

Excel Formulas for Conditional Evaluation

Some of the mathematical functions allow you to add a filter condition. Instead of saying, add ALL the elements in the following range of cells, only add a subset that meets the following condition.

Examples of such conditional excel formulas are: SUMIF(), COUNTIF(), AVERAGEIF()

For instance, in a table of MBA applicants which has a column filled with GMAT scores, if you want to find out the number of candidates who scored 710, you’d use this formula: COUNTIF(A1:A100, 710)

In the family of conditional Excel formulas, the IF statement deserves a special mention. It allows you to test a condition and take an action based on whether the condition is true or false.

Here’s an example: IF ( A1 = A2, “Equal”, “Not Equal”)

This will compare the contents of 2 cells (in A1 & A2) and display the text value of ‘Equal’ if the values match, or ‘Not Equal’ if they don’t.

Excel Formulas for Logical Operations

Here’s the list of basic logical operators: AND, OR, NOT, TRUE, FALSE

You could compare multiple conditions by using AND / OR, and then take the appropriate action.

For instance, consider the formula: IF ( AND (A1 = A2, B1 = B2), “Equal”, “Not Equal”)

This will display ‘Equal’ only if both conditions are met i.e. A1 & A2 have the same values, and B1 & B2 have the same values too.

Excel Formulas for Database Operations

When you are dealing with a table of data (i.e. the values are spread across multiple columns and rows), the VLOOKUP and HLOOKUP functions can make it easy to search for specific values.

This can be a little difficult to understand. So, out pops another example to help us out.

Consider the following table, which displays the column names (A, B, C, D) and Row numbers (1, 2, 3, 4).

A B C D
1 Name Age City GMAT
2 Raj 27 Chennai 730
3 Pooja 25 Delhi 710
4 Vijay 28 Mumbai 680


Now consider the following formulas

Formula 1: VLOOKUP (“Pooja”, A2:D4, 4)

This will cause excel to first scan the cell range (from A2 to D4), go down to Row 4 (i.e. Pooja’s data) and then pick up the value from the 4th column in the cell range (i.e. GMAT score). The value displayed by the forumula is ‘680’.

Formula 2: VLOOKUP (“Vijay”, A2:D4, 3)

This will scan the same cell range (from A2 to D4), go down to Row 5 (i.e. Vijay’s data) and then pick up the value from the 3rd column in the cell range (i.e. City). The output of this formula is ‘Mumbai’.

Excel Formulas for Date & Time

If you had no calendar, no mobile, no way to look at the moon/stars to find out today’s date, what would you do. You’d open up MS Excel and type the date formula: TODAY()

Your little American genie who likes the idiosyncratic MM/DD/YYYY format would tell you it’s 11/20/2014 [or whatever date it is].

You could use nested formulas (one formula within another) to extract specific sub-data from this.

MONTH ( TODAY() ) would give you 11.
DAY ( TODAY() ) would display 20.
YEAR ( TODAY() ) shows 2014.
WEEKDAY ( TODAY() ) would tell say ‘Sunday’ (or the relevant day of the week).

Other date/time functions to check out: DATE(), HOUR(), MINUTE()

Advanced Excel Formulas

The family of Excel formulas is quite large, complex and often confusing.

Once you’ve mastered the basic functions listed earlier, you could check out a few statistical formulas that tend to be used more often than the others: PERCENTILE(), STDEV(), RANK(), GROWTH()

Excel also has several financial formulas: IRR(), PV(), FV(), RATE()

Online Excel Tutorial vs Classroom Course vs Self-Study

If you are a self-starter, the online excel help that comes with the software is well-structured and user-friendly. Don’t get overwhelmed by the full list of basic and advanced excel functions that span across various categories. In fact, you don’t need an advanced excel formulas pdf file to get started.

Just like you would while learning a foreign language, take up a few functions each week and become comfortable with their usage and parameters (‘arguments’). Create your personal excel formulas cheat sheet, instead of relying on the full list of excel formulas. Very soon, your excel vocabulary will grow.

If you find all the technical jargon in the online help confusing, you could take a short 1-2 day classroom course or an online excel tutorial to quickly learn the basics.

Whether it’s MS Excel 2010 or any new version, the software is going to be around for a while. Invest some effort in it and you won’t be disappointed.

    Hi Sameer,
    I am an enginner and MBA, working in a Big 4 in financial due diligence profile. I mostly do financial analysis in excel. I am consedring of changeing my career to Data Analytics, IT or Conuslting. What is your suggestion for me?

  2. Sameer Kamat says:

    VRR: Your expertise in MS Excel and familiarity with financial statements can be an advantage.

    However, roles in Data Analytics and Consulting go beyond the skills that financial due diligence can provide. Check up on the specifics needed for your target job to see where the gaps are. And then work towards filling them.

  3. VRR says:

    Thank you Sameer.

    Can you also please let me know what kind of profiles are suited for me in IT sector.

    Thanks again

  4. Sameer Kamat says:

    VRR: Most mainstream IT roles would require an understanding of the SDLC (Software Development Life Cycle).
    If you aren’t keen to get into development, there are roles ranging from business analyst to software testing that don’t programming skills.

    Hi Sameer,

    I have just completed reading “Beyond the MBA Hype” and found it quite informative and enjoyable. Thank you!

    However, there is one question still nagging me at the back. I am already 36, I have a one year old son and I am the sole breadwinner of my family. If I start preparing now and get some heavenly intervention, at the best case, I would be almost 39 by the time I graduate. Unlike many one-year MBA aspirants who come from the IT Services background, I have a “purely” technical (telecommunications SW) background. Do you think I stand any chance of getting a job at that age?

    Regards,
    SKD
