Out of curiosity, I was looking up some specs for a certain model, & the mpp was quoted ... I never knew there was such a thing.

Another way of expressing pence per mile?

Wouldn’t that depend how much the fuel costs...
So roughly, at £1.50 / litre... 7mpp = approx 45mpg
( Unless I’m reading it all wrong).

Could be to allow comparisons between the running costs of different fuel types. EVs would have a higher initial price and lower running costs whereas ICE would have lower initial price and higher running costs. Using a standardised comparison would demonstrate what would be better depending on the use case?

Cheers... seems that I was way off track then.

But I won’t lose much sleep over it.

Fuel costs only account for about 10% of the total cost of running a modern car.
Depreciation, VED, insurance, servicing and consumables should all count in that figure.

I think 10% is a bit of a blunt assumption.

If I leased something pretty vanilla for 400 a month it probably has VED included so fully loaded with insurance perhaps 450.

If I put a tank of petrol in per week I’m way above 10%.

10% on fuel would fit better with high end cars where depreciation is so savage it certainly eclipses fuel costs.

That depends on how you define modern surely? I can imagine with something brand new depreciation is the biggest figure but once the car is a few years old, fuel would be much more than 10% for most.

In the context of a car for sale, I would imagine depreciation is less relevant than the monthly PCP payment(although they are essentially the same). To get to a MPP you would take this amount which has a set number of miles per year, add the cost of fuel for that same mileage based on manufacturers quoted mpg and an average price per litre, add VED, possibly a servicing plan and an MOT if old enough then divide the miles by this value. Seems fairly straightforward to get a comparable figure this way and would allow better judgement than just looking at the headline monthly payment.

yes Over the 16 years I've owned my current car, fuel has made up almost exactly a third of the total cost of ownership. And that's only averaging about 2500 miles a year, I'd imagine that proportion would rise if the mileage was higher.

Indeed, and depreciation (or however you determine the financing cost of running a car) is the biggest cost.
