Transport/petrol allowance

[WTFH]

Except you're paying road fund licence and insurance whether you use it for business or not.

True, so you have to work out the overall annual cost, then decide do you divide it out evenly across the number of miles you do in a year (no matter the purpose), or do you divide it down over the number of days per year, or some other standard.
Personally I go by miles per year.

I'd take the fixed costs out - MOT, Road Fund, Insurance - I incur those whatever happens. Then split the rest on a work v personal mileage ratio.

What about depreciation/repayments/interest? They are also fairly fixed.
If a car depreciates 60% over 3 years, that doesn't change wildly based on mileage.

Mileage can make one hell of a difference, especially depending upon the make/model of the car; even more so if it's a petrol engine.

In terms of repayments/interest, that's a financing of the purchase issue. Again, I take it as a fixed, given that I was going to buy the car anyway. If the car is going to cost £30k, what mileage I put on it will mainly be driven by my decision to drive it "into the ground" or not; as such, the train v car decision comes into play then.

All irrelevant. You have a car, it costs £x to run, all you're doing is reclaiming the proportion that you dedicate to work usage. If you weren't doing that work mileage then you wouldn't be doing the mileage anyway.

Doesn't help the discussion at all, but thanks anyway.

Capped mileage, the manufacturers don't cap, only some of the lesser finance companies restrict mileage. VW is limited to 999,000 from memory..

Carefully purchased a lease car isn't a bad choice. Each additional mile is 7.2p max with most VW brands which given the 25p mileage allowance covers most of the damage....

Yes. Mrs PC has got a lease car - she drives a lot in her job. Of course, if she does more business mileage and exceeds the limit then its only 8p a mile but the 45p more than covers it (even with petrol on top).

It's moot because the amaps rate is what it is.

But in terms of the cost ascribing the proportion is reasonable (and likely to be somewhat higher than the amaps rate). But so is applying the incremental cost (which is likely to be more closely aligned).

They are both reasonable ways to view it.
