1.Have you any debts? Your priority is paying them off. Go through your spending each week with a fine tooth comb. Set a rigid budget after bills for food - stick to it and set a target for saving each week. No self indulgent treating. No expensive holidays, clothes, meals out etc. until you've saved your target each month. If bus fares / travel is expensive walk more and save.
- It's never too late to save. You need an emergency fund now but even more in retirement. If £20 a month is not doable save £10 or less.
Even £10 a month will be £216 + interest by 67.
3.If you are working part time you should up your hours to full time. This would be my FIRST choice of action. ( Difficult I know, particularly in the present job market.) But, no excuses - I've heard them all." We don't live long in our family so it's not worth my while to save', 'I'd rather spend and enjoy myself now", 'I can't work full time because I like to see my Mum on Tuesdays', 'I like to do the weekly shop on Fridays', 'I like to have more time to myself, ' etc etc.
- Can you retrain for a better paid job?
The advantage of saving into a pension is the tax relief ie you are actually investing £100 for every £80 you put in. The Government gives the extra £20. The advantage /disadvantage ( depends on how you look at it ) is that it is not easily accessible.
An alternative would be monthly saving into a lowish risk investment ISA. £20 a month used to be the least you could save - maybe more now. £40? The risk of investing monthly is lower than putting in a lump sum because if the market falls you get more units : if the market rises you get the gain.
I've never met anyone who said 'I wish I hadn't saved for my retirement' but loads who wish they'd spent a tenth, no a hundredth, of the time they'd spent planning meals out /holidays/shopping all day at weekends on planning their retirement.
My cousin is 81, lives in US. Spent her youth not working, doing PT bits of jobs , no pensions, generally faffing about - she has just retired. A cautionary tale!
If you don't work and save when young, you work when you are old.
