I must have had too much time on my hands when I did this but I did a quick calculation of how much in total it cost for my PPL, including away Landing fee's, equipment (headset, pooley's, etc)and even the petrol cost in getting to the lessons.
Bearing in mind that I took 58 hours in a C152, block booked most of my lesson's in advance with discounts, and had MANY wasted trips up to the school due to weather (35 miles away), my total cost was in the region of £7,500. Don't get caught by the 'minimum cost in minimum hours' trap. It rarely works out that way!! Do your budget, and then add another 20%.
