Last Year on the Green · February: The Lessons Already Paid For

The idea: money already spent cannot be got back by spending more; decide by what is still ahead, and price the exit as it really is.

The Honest Page

Which parts of this story are true, stretched or made up?

True

  • A sunk cost is money (or time) that has already been spent and cannot be got back whatever you decide next. Economists advise leaving sunk costs out of a decision; people often find this hard, and keep going with something because of what they have already put in. Source
  • The opportunity cost of a choice is the value of the next-best thing you give up to make it. Source
  • In the case, ten lessons at £35 cost £350; four taken leave six worth £210, refunded as £180 after a £30 fee. Six lessons at £38 cost £228, £48 more than the refund. Six lessons a fortnight apart take twelve weeks.

Stretched

  • In the case, the refund and the choice of instructor are settled in one afternoon. What we simplified: Driving schools set their own terms for blocks of lessons, refunds and fees, and prices vary from town to town. Read the terms of the school you book with, and keep a copy.

Made up

  • Gale's Driving School, its terms, Mr Gale, Ms Achebe, Juno's lessons and Tara's test date are made up. The idea of a sunk cost is real.
