I've found the best way to track my money is a simple spreadsheet

My days begin and end with the most basic fund management tool you will find – an Excel spreadsheet.

I have been a personal finance writer for about a decade now and have tested many sophisticated tools, applications and online resources. Despite all the latest useful technologies, I always come back to my trusty Excel document. Here's why.

1. it keeps me honest

Although it is tedious, as soon as I can after each purchase, I physically connect it in my Excel document to keep the cumulative total of my monthly purchases by credit card in relation to my overall budget. I clbadify items with colored blocks – yellow for purchases that will be paid on the current account of my husband and my husband, white for those I will cover with my own funds, purple for my health insurance payment and other articles related to health – and so on.

I know that there are online tools that do it for you – allow you to define categories that the system automatically puts into compartments. I used them, and what I discovered was that I was always checking the system for errors or changing compartments anyway. So I thought, why not cut the middle?

2. That's the best way I've found to track my multiple systems

My elaborate Excel system actually consists of several sheets that can actually become cumbersome. However, for a guy like me, I'm not bothered. I keep four Excel documents:

1. Whoever follows our monthly common expenses in relation to our budget
2. A system that tracks my monthly credit card purchases against my personal budget
3. The one who follows the full year of expenses for which I am solely responsible (compared to what my husband pays with his salary) in relation to the income that I plan to achieve for each month (since I am a freelancer, this may vary but follow-up allows me to set monthly goals)
4. The one who follows what is currently in my current account in relation to the bills that will have to be paid in the near future

That's a lot of documents, and I could probably consolidate a bit, but I've been using this system for years, and it works.

It takes me about 20 minutes each morning to check the Excel sheets against my chequing and savings accounts to make sure everything looks right, and I usually end the day with a quick five check minutes.

3. It allows flexibility

As a freelancer, my income can be sporadic and varied. Some months are busier than others and I often have to wait for checks to arrive. Having a system that allows me to manually move things as needed makes tracking easier.

Budgeting and personal finances help you find the system that's right for you, the one that will help you stay in line with your goals. I love the number of products available these days to help people better manage their money. However, if you feel that you have tried everything and still have not found the system you like, let me suggest the simple Excel document. This may surprise you.
