If you can't afford to put money into a pension now, that's OK. Just keep it at the back of your mind.
"There's a rule of thumb for pensions – you should always put in the proportion of your salary equal to half your age when you started. So, if you started at 20, you should put in 10% of your salary throughout your career. If you start at 30, however, you'll need to pay 15% of your salary for the rest of your career, and so on.
"Realistically, very few people can pay in that much – or that consistently. In your twenties, if you do have spare cash to start a pension, you should. Pensions tend to be invested in the stock market, and the longer they're in there, the more chance your investment has to grow – remember, it could be 40 or even 50 years until you retire if you're in your early twenties.
"But, if you have expensive debts, or all your cash is taken up by living costs, then it's not the worst thing that you can't start a pension. But, keep it in the back of your mind – next time you get a promotion, see if you can't put some of that extra cash into saving for retirement." – Helen Saxon
