BTW, welcome to the board, elb!
I see this question about once a month on various boards.
First all the Quicken users chime in ("Works great! Love Quicken!") and then the Money users respond ("Works great! Love Money! Quicken sucks!") and then Quicken users rebut ("You Microsoft weenies, tools of the great evil imperialist monopolistic dictator!") and then someone offers a third choice ("I've been programming Excel macros since 1989 and here's a little gem I just whipped up"...) and the hand grenades start flying.
Quicken or Money both work pretty well. Quicken tends to be much more commercial & relentless in their advertising but I've used their software since 1992 and I haven't been totally disgusted (yet) by their pandering. Quicken is a bonus if you blissfully (mindlessly?) export data to Turbotax. But their main advantage is user inertia-- I'm used to it, it doesn't cost a lot, and I don't care enough to put forth the effort to learn a new program. I only upgrade when I'm afraid that they'll change the data format so much that I won't be able to convert at all. So far that's worked out to be once every 2-3 years.
Money doesn't have all of Quicken's power & options (or Intuit would've abandoned the field years ago) but Money has all the basics plus a few features that Quicken doesn't care about. If Quicken disgusts you then try Money.
Both of these programs may be bundled with computer purchases, other software, mutual fund companies, brokerage accounts, etc. If you can try before you buy then you might avoid wasting $40-$50 and some effort. But I'm not sure that one is better than the other unless you experience a strong personal emotional reaction.
If you have no fear of Excel then do your own thing. The advantage of this approach is that you can include only the features you care about, you won't have to put up with ads or lectures, and you can change the program to suit your needs. And it probably won't mutate its data format unless you tell it to!
Another advantage of Excel is that someone here may have already set up a spreadsheet that they're willing to share. Two other boards where I see a lot of Excel are M*'s "Investing DURING Retirement" and "Hands On" discussion boards.
As someone has already pointed out in another post, Bud Hebeler's "Analyze Now!" website also has some planning/budgeting software that may suit your needs.
