Premium bonds – do you feel lucky punk?

You may remember the character portrayed by Clint Eastwood – Harry Callahan – aka Dirty Harry, who regularly had shoot outs with villains.  As he faced them after a shootout and everyone had lost count of the number of bullets that had been fired, he aims his magnum 44 pistol and utters the words “do you feel lucky punk?”. Such was the ‘enlightened policing’ of the 1960s and 1970s …

Like many of you, I have a bit of a soft spot for premium bonds. There is something nostalgic about them; they feel safe (you are essentially depositing money with the UK Government). You have a bit of a monthly gamble, which unlike other forms of gambling, you do not lose your money if you don’t pick the winner (or place). The winnings are also tax-free and frankly who wouldn’t want to win a million British pounds? Besides, a Premium Bond is only £1 – and you can have up to 50,000 of them.

But let’s be honest with ourselves.

There are around 129 billion bonds in the draw each month. Two will win the £1m jackpot. Your chance of holding the winning bond is 1 in 64 billion.

There are a total of 5,902,600 prizes or winners each month. The chance of winning any sum from the smallest of £25 to £1m is 0.004%. Whilst that looks like a lot of winners (nearly six million) the vast majority (98.77%) win £100 or less. There are only 20,371 that win £1,000 or more.

As most people won’t win, they tend to get out of the habit of checking. At the last time of checking since October 2024, there are unclaimed prizes to the tune of more than £92m.

Yes you get to stay in the monthly draw, but chances do not improve unless you hold more than £24,500 of premium bonds; as the chance of winning any prize is 24,500:1 – in other words £25 winnings for £24,500 – each month – so expected winnings of £300 a year or 1.2%. This is not exactly an inflation-beating rate.

The annual prize rate is 1.4% – that’s the total amount of prizes paid in a year across all the deposits. So if inflation is at 3% or more in the real world, then you are going backwards, more so if you hold less than £24,500.

Meanwhile – deposit rates can be achieved of 3-4% without too much fuss at the moment (March 2025).

Do you feel that lucky? 1 in 64 billion lucky? – they haven’t even inflated the £1m winnings. Perhaps like Harry Callahan, you may not really know why you keep “doing it”, but it certainly isn’t about the interest.
