This post is part of spreadcheats series.
Today we will learn a fascinating little feature in excel called “goal seek”.
But what good is a feature if we cant find a use for it? So we will build a simple retirement calculator using excel.
Before plunging in to the complex retirement calculations, let us spend a bunch of words understanding what this goal seek is all about.
What is goal seek in excel?
We can think of goal seek as opposite of formulas. Formulas tell you what is the output of a bunch of variables used in an equation (for eg. sumproduct is an equation involving + and *). Goal seek tells you what inputs you need to give in order to get certain output.
For example, you can use goal seek to solve a linear equation or find the internal return rate (IRR) of an investment.
Now that you understand goal seek, let us plan your retirement. 🙂
Make a financial model to estimate your monthly savings to meet retirement goals.
(Note: the image shows commas according to Indian currency formatting.)
In order to proceed, we would need some data, like,
(1) What is your current age?
(2) What is your expected retirement age?
(3) How much do you think you will spend every month when you retire (of course in today’s prices)
(4) Your expectation of inflation (%)?
(5) Your expected return (%) on investments?
Once the data is available, we will need to calculate the following,
I have shown the worksheet on the right with some dummy data.
(6) The yearly expenses at the time of retirement: (3) * (1+(4))^((2)-(1))*12
(7) Corpus required to generate the above amount every year (and leave the principle behind): (6)/(5)
(If these calculations are overwhelming, download the excel retirement calculator workbook here.)
We know how much corpus is needed.
We can use FV() formula to determine the future value of a series of payments made periodically and compounded at a given interest rate.
We know how much the FV() out come should be, but we don’t know how much the input (monthly investment) should be.
This is where goal seek is going to help us.
Let us assume the monthly investment amount will be in cell A5. Let us also assume, the interest rate is in cell A4, retirement age is in A3, current age is in A2.
We will write the FV formula in cell A6 like this = -FV(A4/12,(A3-A2)*12,A5)
(we have to negate FV since it uses weird accounting notations)
Since the cell A5 is blank, the FV will show the value as 0.
Now, we will use goal seek to find out how much cell A5 should have so that A6 will be calculated to the corpus amount required.
Go to Data tab and click on What if analysis and select goal seek. (In excel 2003, it should be in tools menu)
See this screen cast to understand how the goal seek works:
The goal seek window has 3 inputs. The cell you need to change. The cell you want to set and the value to set.
Once you use the goal seek it will find the correct (or closest) value to meet the goal and displays it. If you press OK, the value will be placed in the cell (in our case, in A5)
That is all.

Nice roundup! Do you know of any one-page spreadsheets which will be updated by an administrator after each game? Would be nice to be able to print out the latest results whenever I feel like checking them as I probably won't be following closely every day.
I actually haven't tried any of the above ones yet, but I thought I'd mention this one that I found which makes a nice one-page form you can fill in dynamically. http://exceltemplate.net/sports/world-cup-2010-schedule-and-scoresheet/
I would like to recommend you these one: http://www.anotagol.com/
You can choose your interface language (english, spanish, italian, portuguese, german or french) and your country for the timezone of match. I like it very much.
An awesome online world cup calendar in flash.

Does anybody know how to re-create this(?): http://www.marca.com/deporte/futbol/mundial/sudafrica-2010/calendario-english.html
...or do you know where a template can be found? I am DYING to have something like this on my site. When I found it, I had been looking for the longest time for a circular calendar. I found a couple that weren't adequate. Then I stumbled upon this one and my eyes nearly popped out of my head. If anyone can lead me in the right direction, I would be eternally grateful!
Thanks in advance!

@Robert...
Doing something like that is a lot of work. You can probably get it done with some hired help from a flash developer.
@Robert, the World Cup flash in the Spanish Marca newspaper is impresive, but not much as my own animated spreadsheet with the Goals of 2010 World Cup South Africa in Excel that I just published into my blog:
http://pedrowave.blogspot.com/2010/06/goals-of-2010-world-cup-south-africa-in.html
Download from here:
http://cid-6b219f16da7128e3.office.live.com/view.aspx/.Public/Goals%20South%20Africa%20Animated.xlsx
And start to enter the goals of the rest of matches.
Has anyone seen, or made, a Spreadsheet where you can record the scorers and see a 'top scorers' chart. Would be a nice enhancement
@Neil... checkout this one http://www.inflexionary.com/sports/world-cup-2010-excel
it uses macros to fetch scores from web (and provides very comprehensive analysis too)
@All.. Thanks for the comments. I have updated the post with few more links now.

Hey, you missed ours! It has everything you need and more, but not a whole pile of silly extras (National Anthems, etc). I'll be making another one for the 2014 world cup. We had over 4000 hits on it!
