I have just bought a share in a Cessna 172. Cost me £2000 for 1/12th share, very good availability. Hangerage, maintenance and insurance is £50p/m standing order and then it is £56p/h wet. If I decide to sell it down the line I would hope to get somewhere around £2000 back for it.
So taking out the initial outlay as I will get most of my money back when I sell. If I only fly one hour a month (total cost £50 + £56ph = £106) then that would be the same as renting from my local flying club which would cost £111p/h wet for a C172. If I fly more than one hour the costs reduce and basically the more I fly the lower the hourly rate. calculations below:
Standing order = £50
4 hours @ £56p/h = £224
Total = £274 for 4 hours
Average per hour = £68.50
Not a bad saving! Throw on top of that any friends/ family that want to 'see their house from the air' they can contribute towards the costs of fuel etc thus reducing your costs even further.
p.s. I have not included landing fees here as I pay them whether I fly my own plane or a flying club plane.
