Daddy, I Need An Allowance

Unintended Consequences

Parents will recognize the following as the “If You Give a Pig a Pancake” problem, referencing the ubiquitous children’s book about giving a pig the first thing (a pancake) which leads to the next thing (some syrup), which leads to the next thing (a napkin), and so on.

For those of you who have not been parents in the past twenty years and aren’t familiar with the pig & pancake problem, file this one under the “Department of Unintended Consequences” Tab.

Background to the problem

Readers may recall my wonderful, awful, idea a few weeks ago to introduce my eight year-old daughter to stock investing.

Fast forward a few weeks to a conversation she had with my Managing Editor (aka wife) last night.

“Mommy.  I need money.”

“Why?”

“There’s a book fair at school but Daddy took all of my money and put it in stocks.  And stocks are not fun at all.”

“I’m sorry dear.”

“Can I have an allowance?”

“Let me talk to Daddy.”

Ugh.  It is true that I took all of her money.  And converted it into shares of Kellogg stock.

And it’s also true that the steady stream of loose teeth – her main source of revenue via the Tooth Fairy – has dried up lately.  There’s just no telling when the next tooth will drop, and then the school book fair comes up.  Girls who don’t lose teeth don’t get paid.  And then she needs fairy princess dolls, then it’s just all like, bills, bills, bills for my eight year old right now.  You understand what I’m saying.

I didn’t hear about this conversation at first, but I noticed my oldest daughter kept prompting my wife to bring up some particular unnamed topic last night. 

My daughter was eager for the conversation, but my wife strongly preferred that she and I develop a common strategy with regard to allowances, without having to simultaneously negotiate with an eight year-old. 

(Here’s where I ought to insert some analogy between negotiating with 8 year-olds and negotiating with terrorists.  Or lately, negotiating with Congressmen overly responsive to hard-core constituencies, encouraged by a system gerrymandered for incumbency.  But I digress.)

Also, my wife assumed I’d have some strong ideas about what to do when it comes to kids’ finances.  You probably won’t believe this, but I have a lot of thoughts about allowances.

If you give a pig a pancake, pretty soon she'll ask for some syrup

Allowances!

So now we have moved, like the proverbial pig and his pancake, from the “first stock investment” phase to the “allowance phase” of parenthood.  At this point my wife and I haven’t fully decided what to do, although I’m about to explain to you my best ideas so far, at least for the first month of her allowance.[1]

This is one of the cleverest allowance ideas I’ve ever come across, so I thought I’d share before even rolling it out to my family.

Another Wonderful, Awful, idea.

I mentioned this other wonderful, awful, idea once before, buried at the end of a book review I wrote for the excellent The Only Investment Guide You’ll Ever Need, by Andrew Tobias.

You see, I’m always on the lookout for ways to show that compound interest is the most important and powerful math concept in the universe, and Tobias suggests the following children’s allowance plan for driving the idea home.

In fact he lists three great ways of teaching the power of compound interest to kids through the mechanism of the allowance.  Each one has its own special advantage.

Cookie Jar Experiments

The power of compound interest – The Cookie Jar Experiments

Tobias describes three versions of what he calls the Cookie Jar Experiment, which over a month or two can viscerally and intuitively teach the magic of compound interest to kids through the mechanism of an allowance. 

 Version One.  Offer your kid $1 on Day 1, and put it in a cookie jar.[2]  Offer to add 10% more each day, as ‘daily interest growth’ on that original $1. 

So, for example, on Day 2: $1.10 would be in the jar,

Day 3: $1.21.  And then on

Day 4: $1.33. 

After a month there will be a total of $17.45 in the jar, which shows how powerful 10% compounding can be, even if you begin with just $1. 

Tobias suggests you probably won’t continue the experiment to the end of Month 3 ($5,313) or Month 6 ($28 million) but really that’s up to you and your own resources. 

In my opinion, the power of compound interest as a concept is really worth teaching, so some of you will want to consider going the full 6 months.  It will only cost you $28 million in total.  If you do decide to do everything it takes to teach little Johnny the power of compound interest, be sure to email me at Bankers Anonymous so that I can provide my bank account number for the minimal 2% fee I normally charge for this kind of life-changing advice.

Anyway, back to my regularly scheduled commentary.  While ‘real life’ doesn’t let you compound at 10% on a daily basis,[3] the experiment lets you demonstrate the amazing power of compound growth to your kids in a concrete way.

The 1 month time period – by which $1 grows to $17.45 – is short enough that kids can see the growth and just how powerful it can be.

Version Two.  

This next version of the Cookie Jar Experiments is best for two kids, and it can drive home the power of compounding early, plus delayed gratification.[4]

Between your two kids, you offer a similar deal to version one, but with a twist.  If one of them is willing to skip the first three days of interest accrual, they can get something desirable like a chocolate bar.

After they finish fighting over the chocolate, you run the experiment for, say, two months.[5]  The child who went without the chocolate has $304, while the ‘lucky’ child who got the chocolate only has $228 in the cookie jar at the end of 60 days. 

The lesson: Start saving early because it’s the earliest accruing period that matters the most. 

The child with $304 can now buy a whole bunch of delicious cookies and leave the greedy chocolate eater weeping.

Are we having fun yet, kids? 

Kids?  Please stop fighting, please.  Thank you.

Version Three

“If only he’d used his powers for Good, instead of Evil.”

The final version of the cookie jar experiment allows you to compare for your kids the power of compound interest to create wealth to the power of compound interest to dig ditches of indebtedness via credit cards.

Run the same experiment as in Version One, but use the interest rate associated with many credit cards.  Let’s pick 20% because it’s a round number, even though many people’s effective credit card rates are even higher. 

Start adding money to the $1 at a 20% growth rate and label this ‘Credit Card’ growth.  On Day 19 the ‘credit card’ account has grown to $32, versus the $6 to which the original savings at 10% per day grew. 

If you run the comparison all the way to Day 35, the difference is $590 for the credit card account versus $28 for the ordinary 10% growth account.  The key to this version is pointing out that some people scrimp and save and achieve some growth on their savings, while others pay huge portions of their money to credit card companies.

Again, of course, whether you fill up a cookie jar with $590 is up to you and your family’s means, but you can create an unforgettable demonstration for your kids of how small differences in compound interest rates make for giant differences in the medium and long run.

So what will we do about the allowance request?

So will we decide to run these experiments on our children when they request an allowance?

I’m going to push for at least Version One to kick off the new allowance phase for my eight year-old. 

She may not literally be having fun with the fact that all of her tooth fairy money is tied up in Kellogg stock right now, but I’m pretty sure it’s nothing years of therapy in her future can’t undo. 

If she complains, I’ve got a Jack Handey quote ready:

One thing kids like is to be tricked. For instance, I was going to take my little nephew to Disneyland, but instead I drove him to an old burned-out warehouse. “Oh, no,” I said. “Disneyland burned down.” He cried and cried, but I think that deep down, he thought it was a pretty good joke. I started to drive over to the real Disneyland, but it was getting pretty late.”  – Jack Handey

That’s why I say, deep down inside, she’s knows stock investing is fun.  And so are Daddy’s experiments with allowances.

The Allowance Experiment is even better than I expected

 Book Review of The Only Investment Guide You’ll Ever Need by Andrew Tobias.



[1] After that, we may revert to a more typical $2/week, conditional on a usually-left-undone chore – cleanup of the girls’ room – that drives my wife nearly to glue-huffing, out of frustration, on a weekly basis.

[2] Or, wherever.  Do cookie jars even exist anymore?

[3] Except, you know, if you’re a pay day lender.

[4] Also, it pits your children against one another, which is always fun.

[5] Again, adjust to your own means.  And then, of course, send me a reasonable fee if your means are extraordinarily large.

  1. What, no pay for performance? Pay based on grades or chores?

    As a side note, the original book that started the series was “If you give a mouse a cookie”. It came out in 1985 (when I was 2), and was one of the first books I learned to “read”. And by that, I mean I memorized the text and could say it aloud to match the pictures as the pages turned. =)

  2. I love your sense of humor. I’ll bet life at your house is never dull!

    Regardless of what you and your wife decide to do about an allowance, the most important things you can do to raise a financially smart child are 1) be willing to talk with your child about money; and 2) allow her to have control over some portion of her money. It sounds like you are definitely talking about it already so check off #1.

    When you let your child make choices with her “own” money, she is actively practicing money management skills. Responsible money management is a skill and all skills require practice. She may choose to save for a certain item or she may blow it all on the toy of the moment. She will learn from both experiences. It is better for her to make mistakes with a $20 barbie doll than when she gets to college and gets her first credit card.

    Keep us updated on the cookie jar theory!!

      Pam, thanks for your kind words. I very much agree, we all need to talk with our kids more about money.
      Because money is often an adult taboo topic we perpetuate the taboo with our kids, at our peril.
