Which power plan is best for me? Excel for everyday problems

We had to switch power providers soon, so I started reviewing the options. There are heaps of providers in New Zealand and each offer a ton of different plans. Some offer welcome bonus or credit worth up to $ 200. Other offer straight forward rates. Some others offer discount if you sign up for both electricity and gas with them. So how do you decide which one is better for you?

Using Excel of course.

The result is awesome. I ended up saving more than $1000 with a simple model. Puzzled? Curious? Check out this short but powerful video tut.

What everyday problems do you solve with Excel?

While I don’t build models to figure out if brewing coffee at home is better than buying it at local café (home brewing any day for me), I do use Excel quite a bit to answer everyday questions. Recently, I built a model to see how often I cycle vs. walk.

What about you? Do you answer everyday questions using Excel? Please share your experiences in the comments section.

    I use Excel for anything where I need to calculate something.

    I've been tracking my daily spending in Excel for the past 12 years, so I know that when we decided to eat more healthily, we really reduced our consumption of sweets and red meat. It has a dashboard and all.

    I also used it as a family decision matrix to decide where to relocate.

    If I'm not creating a spreadsheet for everything, then I usually think in terms of spreadsheets.

    Applying logic, metrics and rationale to decisions in the same way I would when proving a decision using excel tends to have the same output: a thought out and justified decision.

      hey Hemant,
      there are forums where you could ask this. i'd go with vlookup, pretty sure some of the folks around here would give much more detailed and varied answers!

    Chandoo, you need to check out projecteuler.net and try solving some of them with Excel 😀

    I wish we could go back in town and try some of this excel awesomeness during MAC classes.
