Just a tip - parentheses are not needed due to order of operations, which is the whole advantage of writing it this way instead of (new - old) / old.

Can you explain this function and what you use it for?

Finding specific values in a table where you don't necessarily know which column row the item is in. Similar to vlookup but a bit beefed up.

As an aside, I definitely got dinged at an interview for not knowing this. Then I entered the workforce and literally never encountered a situation where I needed it until ~2 years in.

If you used vlookup instead of index match in my organisation you would probably be fired.

Index match is also more dynamic. If you add columns into a table later, or change the order of columns the formula will not break.

Can you explain when/why you'd used "If(And(Offset(Count" ? creating a dynamic waterfall scenario?

It's actually not properly sequenced.

I use If(And(Count(Offset a lot to be able to change debt structures, reversion period, and to adjust TI/LCs for downtime.

Using count just eliminates the need to number your periods at the top of the pro-forma by counting the dates instead and offset lets you toggle different scenarios listed on the summary tab.

seconding this

other than that, either succumb to the firm preference with LOOKUPS or become exceedingly good at writing a vlookup/hlookup on the fly

It was mind-opening when I realized 90% of reports (at the firm) were done automatically feeding through other software. I feel bad for the guys I know at Morgan Stanley who have to write reports from excel all day every day.

Another man of culture I see... sumproduct is an incredibly versatile formula when dealing with large amounts of arrays

offset, pretty handy

date/eomonth...a lot

hlookup and count and match together, makes an array dynamic for when you add in rows or take out rows and still calculate from the same row.

floating arrays for data are pretty cool too.

Crazy nested if formulas...a lot

Lol, this thread brings me back to the Analyst days of REFing the shit out of a formula and fucking up the entire model then frantically trying to fix it before someone notices.

Haha yep, this is why iferror has become one of my favorite formulas. If you error check everything properly (especially circular references), it becomes pretty hard to key in a letter somewhere by accident and blow up the entire analysis.

Howeva!!...

IFERROR, if used on everything in the world, can slow a sheet and book down, especially if what's inside the () is cross-sheet referencing. I try to limit my IFERROR to things I know have the possibility to error out.

Might be a dumb question, but how do you get super proficient in utilizing these excel formulas? I'm currently in UG and have the REFM Modeling course. Am currently reading Linneman's textbook and taking some RE Finance and Investment Analysis at UCLA Extension. I also have my Argus Cert, but when reading this thread I feel like I am lacking in Excel.

sorry if stupid question, ive seen people mention this but ive never had this issue since im always saving multiple versions of a file im working on....e.g. v1, v2, v3 i dont work directly with debt or anything but i sit next to our Liquidity team and they never have such issues due to making multiple versions each time they make a change or put something through. why does this seem to be different in banking / re?

Everyone here has pretty much covered the most common and useful formulas so I will weigh in on a couple resources for those trying to refine their Excel skills:

• Excel basics: https://excelexposure.com/ is a great spot to start no matter what level of Excel you are at. He lays out a very easy to follow syllabus that is organized by ability level.
• Real estate centric Excel skills: https://www.adventuresincre.com/re-modeling/ is an awesome (and one of few) real estate centric sites and once you have a firm grasp on basic Excel formulas this is a great resource for learning more real estate oriented Excel analysis.
• Other modeling courses: there are a bunch of paid real estate modeling courses you can take that are publicized here, others can weigh in on which provide the most valuable

If you are entrepreneurial and self disciplined however the first two will give you a great basis for an analyst career.

There is currently a battle in my company over the use of the SUBTOTAL command. It's the nerdiest thing ever and it cracks me up.

Team subtotal.

Seconded on SUBTOTAL

when modelling from scratch sumproduct is life.

Don't need much more.

Maybe some sum ifs and minima.

I've been using indirect a lot lately. Has been an incredibly versatile tool in organizing a lot of crazy data

SUMIF
SUMPRODUCT
IF then Nested formulas
Date functions
INDEX MATCH

If I'm pulling in cash flows for multiple months then always index match so I can just drag the formula across without changing column numbers. I'll use VLookup if I'm just doing a simple look up for one value.

large, small can be helpful for me too
other than that, mostly index match, sumif, sumproduct

I agree with most everything on here but I gotta be honest, if you think index is superior to v/hlookups in all instances you're doing it wrong.

I'm curious, when are the lookups better than index?

2 advantages of VLOOKUP beyond the obvious simpler syntax:

1. If switching between sheets, it's much easier/faster to track. With Index/Match you have to switch between the sheets 3 times, with VLOOKUP only once. Can be confusing. Especially when you have to combine more columns for search criteria and especially with new users.
2. If you have to fill in a large and same formatted database with a primary key index, it's much easier and you can copy it easier.

IMM is of course a better tool to use for standardized, repetitive models, but often it's too complex for a small lookup and search function.

I use VLOOKUP much more often, but like IMM for the heavy lifting modeling stuff we do.

Also, there are easy ways to get around the 'fixed' column/row reference and you can make that dynamic pretty easily, so if someone else goes in and deletes/adds rows to the table it won't cause an error.

How many of you Excel guru's can operate without a mouse? I've heard you become light years quicker once you learn all the keyboard shortcuts and hotkeys.

Trying to decide if I want to put in the brain damage to learn or just keep using mouse.

I can use the keyboard for almost all functions. But there are some things that are just too annoying to do without a mouse like some formatting.

What formatting is quicker with a mouse?

Shortcuts probably save more time formatting than they do w/ anything else.

It's pretty simple - just start slamming that alt button.

The vast majority of my work time is in Excel, and I'd say the time saved working through keyboard shortcuts rather than a mouse amounts to a 3-4 hours a week. Definitely worth learning.

Besides obvious ones like INDEX(MATCH), I use these ones a ton:

-INDIRECT
-SUM(OFFSET())
-MID()/LEN()
-CONCATENATE()
-ISNUMBER()

concatenate is too long; just use ampersands in between your concatenation values

Some quick shortcuts I use all the time:

Ctrl + Shift + & = puts boarder around selected area

Ctrl + Shift + - = Erases all boarders in a selected area

Ctrl + Shift + \$ = Aromatically puts numbers in Currency format (Although most like to use Accounting format without "\$" sign, so Ctrl + 1 = brings up format window and just use Tab key to get to accounting and put in "none" for currency symbol and 0 decimals)

Ctrl + [ = shows exactly where cells are in a selected formula by highlighting them. I like it better than tracing dependents/precedents

Alt + H + 0/9 = increase or decrease decimals. I for some reason find myself using this a lot

Good comments above. Some of my favorites:

1. I use SUMIFS for multi-conditional summations rather than array formulas since it seems faster. Similarly with its sister functions like COUNTIFS and AVERAGEIFS. Though, be careful with AVERAGEIFS since it is a simple average rather than a weighted average.
2. For other multi-conditional calculations that the aforementioned formulas can't handle, I use array formulas. While array formulas are great to get a lot of calculations done in one cell, I recommend using multiple columns to "show your work" for more complex calculations. This helps you diagnose issues and make your worksheets easier to understand.
3. Lastly, I use PivotTables all the time. While not a formula per se, they are extremely useful. The trick I use most frequently with PivotTables is calculating weighted averages. See here for how to use a Calculated Field to determine the weighted average within a PivotTable. Simple averages can cause misleading conclusions, so I generally calculate both a simple average and a weighted average since this helps reveal outliers that may be driving a divergence between the two averages.

I like commenting when I have long formulas using +N("COMMENT").

Also, recording macros and editing them a bit if you find yourself repeating something across many tabs.

I'm just an intern, so probably what I use is different. But I use a lot of vlookups, sumifs, if combined with and/or. I know that these aren't formulas, but a lot of work with the shortcut keys.

IF() - mixed with AND()/OR()
EDATE()
SUMIF()
INDEX/MATCH
SUMPRODUCT
DATEDIF - (MOD(DATEDIF)) - handy for quarterly/bi-annual payments
IFERROR - careful with this one!
DATE()-YEAR()-MONTH()
NORMDIST() - for my s-curves
MAX/MIN
PMT() - for investment loan calcs
