It’s a bit demoralising seeing what others seem to get nearly every month while mine has been so poor. Not sure how much longer I will leave them. It’s just this anticipation that next month will be better that has stopped me taking them out so far.
Do not be demoralised - it depends totally on how much you have 'invested' in PBs. Those who win larger sums regularly probably have the full amount of £50,000 tucked away in PBs. Or somewhere near the max.
Another (better?) way of looking at it is in percentage terms. If your total winnings in any 12 month period exceed what you would gain in interest if you had your money elsewhere, then you are doing well. The last 2 years I have achieved 3.2%, which is much better than previous years, and am happy with that. This year is around 5% and I am astonished as I do not have anywhere near the max!
If I was only getting around 1% or 2%, I would seriously consider moving out of PBs. But some folk stay with them hoping they might win one of the very large prizes.
The other aspect to consider is the PB prizes are tax free, which may or may not be relevant to your financial situation.
