$200k for a coffee and sandwich?

I'm reading "Playing with FIRE" by Scott Rieckens. He realised he could save a 6-figure amount just by not having a sandwich and coffee on his way to work each day.


Traditionally Scott would buy an coffee and a sandwich on his way to work. It was "only" eight dollars so it seemed like an easy purchase.

Even with free coffee at work, eight dollars seemed a small price to pay with a sandwich included.

Doing the Math

Then Scott crunched the numbers. Eight dollars each workday came to $160 a month. $1,920 per year.

Continuing this habit for 30 years of work would cost him $57,600.

If he invested that $160/month instead, he would accumulate $133,161 (invested at 5%).

Translating that into Australian dollars it's $194,765.27 (to be precise).

How the little things add up

It is amazing how even little things add up if we do them a lot. $8 doesn't sound much - until he realises he's buying 7,200 coffees and 7,200 sandwiches.

Are we getting value?

This is not to say don't ever buy anything. It's about working out whether we're really getting value from our purchases.

Repeat purchases are particularly in question - for two reasons. Because we do them often, the cost really adds up (like the coffees). We also know that the longer we have something the less we enjoy it.

So how much does stuff really cost?

Good question. I developed my own little calculator for this (grab a copy).

I tried an example of a $14 lunch each workday. It came out to cost nearly quarter of a million dollars.


Download your own copy and you can try it out for different expenses, whether they occur each workday, every day, week, month or year.

I'm not picking on coffee drinkers. It might be buying clothes you don't wear, having a gym membership you never use, or cable TV that you don't need.

By finding out the true cost you can decide whether it's providing good value, or whether you'd be better off with the cash.

The real cost of owning a car

It's been about 10 years since I've owned a car. My wife doesn't own one either. "You must save a lot in petrol" That's one of the frequent reactions when someone discovers we don't own a car. "Of course, but it's just the tip of the iceberg" is the usual theme of my reply. Many people I've talked to just aren't fully aware of the real cost of owning a car. Or even that there are six different costs of owning a car. Six? Really? Yes. Occasionally a work colleague or friend will boast their car only costs $X per week. Of course it turns out only some factors have been counted. Sometimes it's just petrol alone. To some people, that feels like the only cost they pay each week. Why does this matter? You might be questioning the need for a second car in the household (or even having one at all). Or you might just be choosing which car to get next. Either way, to make an informed decision we need proper information. So let's look at...

Man Down

How is it possible for a book to be depressing, supportive and hopeful all at once? Man Down looks at the problems men have today and how it managed to get this way. What price 'success'? It seems so many of the problems come from the external pressure to be a 'success' - whatever that means. Over time this pressure becomes internal and drives us to make decisions to satisfy that pressure, but which are detrimental in so many other ways. It can be the pressure to take a 'successful' career, though it's one we don't want or aren't suited for. Or to take a promotion, because salary is apparently success - or at least it buys all the things that signal success to others.  The promotion only means more pressure, less sleep, and poorer health. At the same time the extra responsibility takes away from our ability to exercise, take care of our health and form social connections. The lack of social connections means that retiring is one of the most dangerou...

The rule of 72

Here's a superquick way to work out how much money your investments might make. No need for fancy exponential maths . Just simple division and some doubling. Maybe you can even do it it your head. The rule of 72 Years to double = 72 / growth rate That's it. Pretty simple. Just 72 divided by a number. Working out the double-time So a 2% investment would take 36 years to double in value. (72 divided by 2) At 6% it would take 12 years, and at 8% it would take 9 years. How many doubles? Let's say someone is investing $50k for 36 years. At 2% , it would double once. Result $100k . At 6% , it would double three times. (36 years divided by 12 years). Three doubles means it becomes 100k, 200k, then $400k . At 8% , it would double four times. (36 years divided by 9 years). Four doubles means it becomes 100k, 200k, 400k, then $800k . This is astounding I was stunned when I first came across this. I probably still am. It's amazing to think that moving from 2% to 6% changes things ...
