Cost per mile

Postby PorlyWorly » Tue Oct 30, 2012 12:30 pm

Prior to cycling I drove a silly japanese import which returned 14mpg and got the idea from the car forums about logging what I'd spent on the car and translating that into cost per mile.

1st of November 2011 I committed to cycling to work most days and a year on I am now commuting on my bike 99% of the time, I only take my car if I need to transport something I can't carry on my back.

I've kept a spreadsheet of everything I've spent and have used strava/endomondo most of the time from day one. Biggest outlay was a second hand Genesis Equilibrium 20 but taking into consideration all of the clothing, tools & accessories, a year in I am in for a total of £1,333. I've only spent £60 in the last three months (£40 of which was on a full service to overhaul the running gear replacing all cables etc.). I have all of the gear I need to get through winter, only thing I might need is some winter tyres!

I've done 1965 miles so far and will hit the magic 2000 before 1st Nov. Estimating the resale value of my bike and gear at a conservative £650, cost per mile for the first year is £0.34.

Here's to the next 2000 miles!

Bit geeky, but I've been logging this for 7 years.
Managed to spend £15.5k and ridden nearly 41k km .... which is nearly 60p/mile.

But then I must have £5k worth of stuff and have saved over £4k on tube fares.

This is something that I should consider doing so SWMBO can see why i need new things all the time!

Bike, £120
Clothes, shoes, lights, tools etc, £300
Replacement parts, £500
Consumables, £100

Miles 15,000

About 6p/mile not including extra food

I did a rough calculation when buying the Fratello and I should break even by the end of the year.
As I have all the gear that I need (plus a lot extra) I will be saving money by cycling in 2013.
None of the above should be taken seriously, and certainly not personally.

I don't keep a full spreadsheet, but in London you're saving £112 (£1340 a year) a month on public transport if you commute by bike. Thereby totally justifying any expenditure on bike stuff entirely.

Depends on where you cycle in from surely? I assume you mean living within a certain zone...not being a London worker I need to ask what is maybe obvious, for that I apologise.

I wish I lived in Central london with a travel card that costs that.

Mine would be £190 monthly or £1992 annually.

I think an annual season ticket from my gaff into town is circa £3.5K.

just as far as food costs are concerned (working not shown) last time I calculated it, based on the average person's calorie intake and the national average spend on food (just under £5 per person per day), and assuming 50 kcals per mile, it costs about 11p per mile in extra food (fuel) costs over and above a sedentary food requirement (ie not including Base metabolic rate) to run a bike assuming a decent mileage per week (100+?)

lets assume the average serious cyclist spends about 3 times more on his bike than the average motorist spends on his car!

Good thread (okay, so I'm a geek).

I've not worked mine out (I daren't!), but I justify my 12 mile commute by the fact that the alternative, taking my VW Transporter van, costs about £4.40 for the return trip, just for diesel, so after a few commutes I've racked up some savings.

Truth is the "savings" are spent on shiny bike stuff but, hey, I'm fit and healthly so what's the value on that?

Why assume that?
Seriously curious. My spending was the reverse.

I'm saving upto £140 per month on travel card (if i cycle every day) plus £60 a month on gym membership. I have no idea what I've spent on bikes etc but I suspect I'm at least cost netural since I started in sept 2008

That wasn't intended as a serious remark sorry about that, it was a ' many a true word is said in jest' type of thing! I have calmed down a bit myself, but in my first few years of cycling addiction, my wiggle and CRC accounts got a serious going over ! Lol

I would also say that the extra cost of fuel (extra food) is a cost of cycling reasonable distances that is often convieniently left out of the equation. The cost of an average calorie of food in the uk is £5/2200 kcals. Excluding base metabolic rate, it takes 50 kcals to cycle a mile. Therefore average fuel costs for a mile of cycling is 11p. This compares with a small car according to the AA.

Umm, nope... I think you are experiencing a perspective failure, here: Eating more isn't a cost, it's a benefit, unless you're actually too close to the breadline to be able to afford shiny bike stuff... :-)

Have to say, I'm in the same boat as you. I'd far rather be eating my fuel bill in the form of extra chips at the canteen and my egg, bacon and black pudding butty I'm the morning than standing on the forecourt ! My colleague are eternally jealous of my capacity to totally pig out whilst maintaining a six pack and being sub 70 kilos! That said , if we are being geeky about the cost of cycling, the cost of the food used to fuel it should not be left off the spreadsheet.

They do but the average male driver who commutes 20 miles a day needs to eat 2200 calories to cover their base metabolic rate plus the calories required to sit at a computer all day. A cyclist uses at least an extra 1000+ kcals on top of this base calories. Cycling uses 50 calories per mile roughly over and above base metabolic rate.

I cycle between 100 and 150 miles a week and need to eat around 4000 calories or I start to loose weight and there's nothing of me as it is!

Provided I keep on cycling till March 2013, I will be cost neutral. However I am struggleing wifh motivation. The biggest benefit I hope is just being healthier.

This is not a very well thought-out calculation. It might be reasonable to assume that you could get most of your extra cals from carbs, which come in (tesco value pasta) at 60p/kg: that's about 40p/2200 kcals.
Moreover, your 50kcals / mile is a bit much - a fit rider going fast might just use that in total, but for most it will be quite a bit less.

So in fact, food-wise it would be less than 1p/mile. A bit different I think.
