10 Free Calculators to Help You Handle Your Personal Finances

by Guest Blogger on 2008-02-2217

Ooooh. Calculators galore! For the money nerd in you.

Gone are the days when all that we had to do was balance our checkbook once a month to keep track of our money. It seems like our financial affairs have grown more complicated in lock step with the rest of our modern lives. In the world of personal finance, we’ve seen new tools emerge to help us with our money management, while we do away with older habits. For instance, who still writes checks? [Okay, I still do, but not as often as I used to!]

However, your situation may have complicated itself (hopefully in a good way) to the point that some external assistance is necessary to keep things in order. If you haven’t quite reached the point that you can hire someone else to organize and analyze everything for you, then these simple tools will help you do it yourself. They are easy to access, easy to use, and best of all, easy on the budget.

Net Worth

Figuring out what you have is as good a place to start as any. This net worth calculator will not only help you determine your current net value but it can help you determine how it can change over time.

Life Expectancy

Now that you know how your finances will change over time, it might be useful to determine just how much time you’ve got. This calculator will estimate your life expectancy based on aspects of your current health and the lifestyle that you enjoy. Is this a bit morbid? Well, sure it is; but it’s also dead useful.

Wow life is getting complicated. Feels like too many calculators are needed to get a financial situation “right” 🙂

Seriously, I think calculators can sometimes be misleading if one doesn’t understand the basis for the estimate or how to use the info.
In most cases, I prefer ranges and scenarios versus a single number. Hmm…probably a topic of a future post 🙂

@Super Saver,

True that without context, calculators may give you inaccurate ideas. But I guess having some idea is better than nothing. A ballpark financial figure is something I may still be able to work with. But you’re right, calculators may come across as a “one size fits all” remedy but I look at them more as simple utilities to enhance my financial projections.

I found the calculators very interesting especially the cost of living one, even if you aren’t really considering moving it is still very interesting to see the comparisons.

For your information, there is a great little online personal budgeting website that is totally free and truly anonymous. It lets you open your private budget account with just your e-mail and asks nothing more from you.

You are immediately given a great looking, easy to use straight forward budget page, and you can also generate monthly reports to your e-mail for safe keeping before end-of-month closing and starting a new month. The budget categories are not user modifiable but the set is very rich and flexible covering just about any practical category plus a few catch all miscellaneous category, not a bad deal for a free utility. And there is an instant super easy to use online users billboard that holds discussions among users and the developer too.

The website is at:

Happy budgeting.

My investment goal: keep asset allocation balanced. Maintain 70% equities to 30% bonds/ cash unless we get a significant correction. Then, go to 80% equities and 20% bonds/ cash. Otherwise, invest all cash over 30% at the end of each month at Zecco. com.
