 A Coffee Tale

“The $200,000 Coffee Maker”

In December of 2006 my two oldest children came home from college for their winter break. My son was a senior and my daughter was a sophomore. For those parents out there that don’t know this yet, college-age children are not early-risers. However, for some strange reason one morning the entire family was up early and my wife and I were having our homemade lattes. We use a very old-fashioned and inexpensive espresso maker and we heat up the milk ourselves. We don’t think much about it. As the morning progressed I notice that both my seemingly intelligent son and daughter are also drinking lattes. However, they’re not drinking the homemade kind like my wife and I drink but the fancy expensive kind that you get from Starbucks or other upscale coffee houses.

I was a little bit miffed at the situation to say the least. I clearly saw their upscale coffee expenditure as an unnecessary extravagance. I’ve always preached the old refrain of a penny saved is a penny earned and yet right in front of me was empirical evidence that I had not proven my point. In order to procure their precious nectar one or both of my children had to get in a car, drive, spend money on gas and auto depreciation, risk injury or worse and finally pay an exorbitant price for a latte they could have easily made at home for a lot less effort and that in my opinion tastes much better.

I didn’t say anything but I went into my home office and ran a quick Excel spreadsheet and with some very conservative assumptions came back with some startling information to share with my children. I wanted to illustrate the refrain of a penny saved is a penny earned in a practical and everyday sense. The overpriced lattes gave me the perfect avenue. I developed a model where a 22 year old chooses to fore-go the daily store bought latte and instead makes it at home until age 65. I assumed the daily savings at $1.70 and an interest rate of 8% invested once a year.

I then gave my latte loving children a quiz. I asked them to estimate the difference in cost between the lattes they drank and the ones my wife and I drank. I then asked them to estimate how much they would save over the next 43 years if they prepared their lattes at home vs. buying them from their coffee house of choice. Let’s just say that their estimates were significantly below mine. They had underestimated the power of compounding over 43 years as most people do. They were guilty of a common financial sin. When I showed them the spreadsheet results they were surprised. So what’s the savings? By my estimate a person saves $204,506 by making lattes at home vs. picking one up on the way to the office. It just takes $1.70 per day at an 8% interest rate for 43 years to save more than $200,000. See to get a fuller understanding of the power of compound interest and savings. This tale was meant to illustrate the power of counting the pennies in our everyday life. I am sure that for those that truly understand this tale they can come up with creative ways of stretching the dollar and putting themselves on the road to financial success.

A few days later my latte-drinking children each received their own $14.95 espresso maker as Christmas presents. Inside was a note labeled the “The $200,000 Espresso Maker” love Santa.

  1. i like your bio.

  2. I adore this tale. I can totally relate to it!

  3. How true, How true!!!!! Do you think our kids understand your latte lesson???
    Would love to see you guys…why don’t we meet at a Starbucks real soon.

  4. Loved this tale since I am always preaching a penny saved is a penny earned. My son has 2 lattes each and every day going and returning home from work as his treat for the day. I quickly calculated the amount he was spending per year and told him he could drink his own coffee while at home and save the foolish spending. I will now forward this to him and he will know I am not alone in my thinking. A good coffee machine is in order for his present at Christmas time. Thanks. Sorry Starbucks…

  6. 43 years? not too practical. but the savings is still noticeable even in the short term! $50 a month is a cell phone bill…
