Premium Bonds will give a poorer return from the May 2017 draw. So are they still a good place for your savings?
The changes to premium bonds announced on 8 February do not affect their value as a good place for your cash savings if you fulfil three conditions
- You can buy the maximum £50,000 or close to it.
- You pay higher or additional rate income tax.
- You have used up your personal savings allowance with interest on other savings outside ISAs.
- the nominal interest rate is cut from 1.25% to 1.15%
- the distribution of the prizes at the lowest end has been altered
From May those three prizes will still take the same proportion of the money and prizes. But the number of £50 and £100 prizes will fall to just over 20,000 each. The number of £25 prizes will rise to 2.2m, which will be 98% of the prizes, and take 85% of the prize money.
When considering the actual interest earned in any realistic timeframe it is those three lower prizes that should be counted. With £50,000 bonds you can expect to win a £50 or £100 prize once every five years in future - it was two years. That means the effective interest rate - the money used for the prizes you might win - is 1.04% from May compared with 1.13% before the changes. So if you can take a five or ten year view of your money that is equivalent to earning 1.29% taxable interest for a basic rate taxpayer, 1.73% for a higher rate taxpayer and 1.88% for a top rate taxpayer.
With 50,000 bonds you will expect to win 20 of those lower prizes a year – the same as before May. The vast majority will be for £25. Of course chance will not produce an even return. But over time that should be the average. Here is the monthly 14 month prize record of one £50,000 holding I am familiar with 3,1,1,0,0,0,1,1,2,5,2,2,2,2. All were for £25. It is a rate of 0.9% a year tax free.
Even with a maximum holding you can only expect to win £500 or £1000 once every 22 years (up from 20 years). The larger prizes of £5000 and more are far more sparse. If you had bought £50,000 premium bonds in 770 when King Ahlred was on the throne of Northumbria and sending missions to the continent you would expect to have won just one larger prize by now. You will wait another 1247 years until the year 3264 for the next.
With smaller amounts of bonds, prizes of course are much rarer. £100 gives you an even chance of winning a £25 prize every 25 years. With one bond bought when when Stonehenge was built you might have expected about two prizes by now.
So Premium Bonds are still good for people who can afford to buy the maximum who are higher and top rate taxpayers and who have used up their personal savings allowance with interest on other savings. That probably means £30,000 to £50,000 in other savings products on top of any cash in ISAs. Additional rate taxpayers do not get the personal savings allowance. More than half the bonds are held by people who have at least 30,000 of them.
ERNIE (Electronic Random Number Indicator Equipment) who draws the winning bonds each month is not a computer. However hard they try computers cannot produce genuine truly random numbers. So ERNIE uses a process which was invented by a Bletchley Park codebreaker called transistor thermal noise to create truly random events which are then counted and combined in turn into bond numbers. Every month the Government Actuary checks the prize list for randomness before the prizes are paid.
Because every bond really does have an equal chance of of winning there is no point in cashing in 'unlucky' bonds and buying new ones. Doing that also means there is a month between selling and buying when the bonds are not in the draw. So it worsens the odds of winning.
Personal Savings Allowance
The personal savings allowance which began in April 2016 means the interest on savings is tax free up to £1000 for basic rate taxpayers and £500 for higher rate taxpayers. So the tax-free prizes are of most value to those who have other savings which have used up those allowances. Additional rate taxpayers do not get the personal savings allowance. So premium bonds are very good for them.
