Know the headline number
Saving £1 in week one, £2 in week two, and so on until £52 in week 52 results in £1,378 in total. It is the sum of the integers from 1 to 52.
Adjust the pace
You can begin at less than £1 or use a smaller weekly increase. A flat weekly saving amount can be more predictable than an increasing challenge.
Plan for the later weeks
In the classic version, the final four weeks alone require £202. That can be a significant amount, especially towards the end of a busy year.
