Cash allowances still make sense, but how do you set up a system that works for you and your tech-dependent kids? By Janet Bodnar, Editor-at-Large January 24, 2007 In an era of online shopping with virtual cash, many parents are struggling with two issues, reports the Wall Street Journal: whether to continue giving their kids a cash allowance and how to set up a system that works.The first answer, in my opinion, is easy: A cash allowance still makes sense. And the second isn't too tough either: The basic rules still work and can be adapted to allowance 2.0. Start at an appropriate age. Children start learning about money in school at age 6 or 7, and that's when they also begin to appreciate how far it will stretch (younger kids don't always grasp that). Start with a weekly allowance equal to half a child's age, which you can adjust up or down. Don't tie the basic allowance to chores. Some families are incredibly well organized. But in my experience many parents have a tough time keeping track of multiple chores over the course of a week. Even with online chore-tracking sites, the system can collapse under its own weight.

Make kids responsible for some of their own expenses: collectibles, movie tickets, after-school snacks -- or, with allowance 2.0, music downloads and online games. To link pay with work, pay for "extra" jobs as soon as your kids complete them. That's easier to monitor than a week's worth of chores. Keep it simple. When my children were younger, we kept track of their money with a simple checkbook system. Each month I'd record their allowance (plus gift money or other income) in a checkbook for kids. When they wanted money, they'd write me a check and subtract it from their balance. We always knew where they stood. In the Wall Street Journal story, one mother had worked out a similar system for allowance 2.0: She uses her BlackBerry to keep tabs on her kids' accounts.

Chasing after them to reimburse you has always been a losing proposition, and that's even more true if they've used plastic to buy online music downloads or video games. If the kids want to spend $10 or $20 on, say, iTunes, have them give you the cash first and you can load it on the account. It may cost you a little effort, but the lesson is worth it.
