Some people scoff at this method and say "well, why don't you just save £26 each month, or as much as you can afford rather than using this chart" It's a valid point, and if you have the means and the will power to save in this manner then by all means do so. The beauty of this method is that it eases you in to the idea of saving. It's really well suited to those that have never saved before, and those that think they simply can't save.
Having said that, this method isn't perfect. Life is full of surprises, some good, some bad and the truth is we all have those unexpected expenses such as the car going wrong, or a boiler conking out. Don't worry too much if you don't meet your target for a certain week, make it up in following weeks if you can - or not at all. You'll still have a healthy sum at the end of the year and perhaps more importantly you will have proved to yourself that saving perhaps isn't as hard as you might have thought.
Even little things like going without that overpriced coffee in the morning, or staying in some weekends goes a long way. When you have saved enough to earn a nice holiday or to pay off those lingering debts I guarantee you won't regret it!
Another criticism of this method is that it requires you to save the largest amount of money around Christmas time, which for most of us is the hardest time of year financially speaking. That's a valid point but who says you have to start in January? You are free to start whenever suits you. It is just a guide after all, not a religion.
The Reverse 52 Week Challenge
This take on the method simply reverses the chart so that you start off paying in the largest amount and slowly decrease your contributions. This plunges you in at the deep end and eliminates the manageable curve in saving. If this appeals to you more then by all means go for it!
Tailor the plan to suit you, maybe a monthly plan suits you better, maybe you can afford to put away more than the method suggests, double, triple, even quadruple it if your circumstances allow for it. Give yourself breathing space. You might find it easier to just put as much away as you can each month, depositing the suggested amounts whenever suits you rather than simply increasing week on week.
