This is far too complex to answer from my point of view as all circumstances are different. My present outlay has been £22.5K purchase, £70K refurbish. Things to take into account:
1. Purchase price
2. Insurance
3. Basic servicing costs
4. Hourly running costs.
5. Admin fees: Clubs, CAA etc.
6. Annual costs (Permit of C of A), radios, fatigue meter (if you have one) etc.
7. Hangarage or parking.
8. Landing fees.
etc etc
It all depends of what you have, what you do with it etc. Have a look at other threads on this forum. Have a word with the LAA.
Incidently, my basic costs (not incl fixed) are in excess of £200 per hr. As they say, if it floats, flies or f**ks, then rent it!
