Premium Bonds vs a savings account
Premium Bonds or a savings account? A plain UK comparison of the odds, the prize rate, tax and safety, so you can decide which suits your money better.
A savings account pays a guaranteed rate of interest, while Premium Bonds pay nothing guaranteed and instead enter you into a monthly prize draw — so a savings account usually suits people who want reliable returns, and Premium Bonds suit those who value tax-free prizes and the chance of a big win.
The core difference
A savings account is simple. You put money in, the bank pays interest at a set rate, and your balance grows steadily. You know roughly what you will earn.
Premium Bonds, run by NS&I, work differently. Instead of interest, every £1 bond is entered into a monthly prize draw. Prizes range from £25 up to £1 million, and they are tax-free. But there is no guarantee — in any given month you might win nothing at all.
One pays a steady, predictable return. The other pays an unpredictable one, with a lottery-style thrill on top.
The Premium Bonds prize rate and odds
NS&I sets a prize-fund rate, which is the average return across all bonds. From the July 2026 draw it is 3.80%, and the odds of any single £1 bond winning a prize are 22,000 to 1.
Both numbers change regularly, so always check the current figures at nsandi.com before deciding.
The catch with the prize rate is the word average. A few big winners pull it up, so most people actually earn less than 3.80%. With average luck and a smaller holding, you might win nothing for months. The more bonds you hold, up to the £50,000 limit, the closer your returns tend to track that average.

The tax angle that often decides it
Premium Bond prizes are always tax-free. Savings interest is only tax-free up to your Personal Savings Allowance, which for the 2026/27 tax year is £1,000 for basic-rate taxpayers, £500 for higher-rate taxpayers, and £0 for additional-rate taxpayers.
If your savings interest stays under your allowance, a good savings account often wins, because the return is guaranteed and untaxed anyway. If you are a higher earner already using up your allowance, the tax-free nature of Premium Bonds becomes far more attractive. A Cash ISA is another tax-free route worth weighing up — the ISA allowance is £20,000 for 2026/27.
Which suits you
There is no universal winner. It comes down to what you want from the money.
- Choose a savings account if you want a steady, predictable return, you are saving towards a goal with a deadline, or your interest sits within your Personal Savings Allowance.
- Choose Premium Bonds if you have used up your tax-free allowances, you like the idea of a tax-free flutter with no risk to your capital, or you simply enjoy the monthly draw.
- Many people hold both — a savings account for the reliable bulk, and some Premium Bonds for the fun.
Whichever you pick, it helps to see them next to the rest of your money. Oinkly can track savings accounts and Premium Bonds together, so you know what your whole pot is really doing — see how to track all your savings in one place.
What you might actually earn
The prize-fund rate makes Premium Bonds sound like a savings account paying 3.80%. For most holders they are not, and it helps to understand why before you decide.
The rate is an average pulled upwards by rare large prizes, including the two £1 million jackpots each month. Strip those out and a typical holder with average luck tends to earn less than the headline figure. With a small holding you might go several months winning nothing, then get a £25 prize. The larger your holding, up to the £50,000 limit, the more your returns smooth out towards the average.
So the fair way to think about Premium Bonds is not as a fixed return, but as a tax-free savings pot where your return is variable and, for most people, a little below the advertised rate — with a small chance of a life-changing win. If a guaranteed number matters to you, a savings account or Cash ISA is the clearer choice.
Where they fit alongside ISAs
It is not only a two-way choice. For tax-free saving, a Cash ISA sits between the two: it pays a guaranteed rate like a savings account, but the interest is always tax-free like a Premium Bond prize. The ISA allowance is £20,000 for the 2026/27 tax year.
A sensible order for many savers is: use your ISA allowance for guaranteed tax-free interest first, keep an easy-access account for money you might need soon, and then consider Premium Bonds for spare cash once your allowances are used, especially if you are a higher-rate taxpayer. Oinkly can track ISAs, Premium Bonds and ordinary savings side by side, which are Big Pig features, so you can see the whole mix at once.
Frequently asked questions
Are Premium Bonds better than a savings account?
Neither is always better. A savings account gives a guaranteed return, while Premium Bonds offer tax-free prizes with no guarantee. Higher-rate taxpayers who have used their allowances often prefer bonds; savers who want certainty usually prefer an account.
What is the Premium Bonds prize rate right now?
The prize-fund rate is 3.80% from the July 2026 draw, with odds of 22,000 to 1 per £1 bond. Both change regularly, so check the latest at nsandi.com before deciding.

Yes. They are backed 100% by HM Treasury, so your capital is secure. Savings accounts are protected separately by the FSCS up to £120,000 per person per banking licence.
Do I pay tax on Premium Bond winnings?
