Premium Bonds Prize Draw 2026: How the Odds Work, Average Returns and Whether It Is Worth It

Premium Bonds are one of the longest running UK savings products. Around a third of UK adults hold them. Instead of paying interest, NS&I enters every eligible bond into a monthly prize draw. Prizes run from £25 to £1 million.

NS&I has confirmed the prize fund rate at 3.30% (variable) until the June 2026 draw, rising to 3.80% (variable) from the July 2026 draw. The corresponding odds per £1 bond per month go from 23,000 to 1 to 22,000 to 1. This guide explains how the prize fund actually works, whether the headline rate is a fair comparison with savings accounts, and how to decide whether Premium Bonds suit your money.

How Premium Bonds work

Each £1 invested buys one bond. Bonds become eligible for the prize draw from the first month after they were bought. NS&I uses a random number generator called ERNIE to draw prizes each month.

Minimum purchase is £25 per transaction. Maximum total holding is £50,000 per person. Holdings over £50,000 are not eligible for the draw.

Prizes range from £25 to two £1 million jackpots a month. Prizes are paid by direct credit to your bank account if you have set that up, or reinvested into more Premium Bonds.

Premium Bonds are backed by HM Treasury. The capital you put in is fully protected. Like all NS&I products, Premium Bonds are not covered by the Financial Services Compensation Scheme because the underlying guarantee comes from Treasury directly.

The current prize rate and average return

The prize fund rate is 3.30% (variable) until the June 2026 prize draw. From the July 2026 prize draw it rises to 3.80% (variable). NS&I quotes the rate as 'variable' because it can be changed at any time by the NS&I board on Treasury direction.

The prize fund rate is the average return across all eligible bond holders. It is calculated as the total prize fund for the month divided by the total amount of eligible bonds in the draw. An individual holder might receive more or less depending on luck.

All prizes are tax free in the holder's hands. For higher and additional rate taxpayers, the tax free status can make the after tax comparison against a regular savings account more favourable, even if the headline rate looks similar.

The odds, in plain English

Until the June 2026 draw, the odds of any £1 bond winning any prize in a month are 23,000 to 1. From the July 2026 draw the odds improve to 22,000 to 1.

What that means in practice: a holder with £1,000 in Premium Bonds will, on average, win about half a prize per month at the new odds (£1,000 divided by 22,000). Most months will be zero prizes; some months will be a £25 or larger prize.

A holder with the maximum £50,000 stake has roughly £50,000 divided by 22,000 = 2.27 expected prizes per month. The vast majority of those prizes will be £25 each. Returns scale with the size of the holding.

Because prizes are bunched at £25 and the headline rate includes very rare large prizes, the median return is lower than the mean. A typical small holder may experience prolonged zero prize stretches.

When Premium Bonds beat an easy-access savings account

Compare the after tax Premium Bonds rate against the after tax savings account rate. For a basic rate taxpayer with savings interest above the Personal Savings Allowance, savings interest is taxed at 20%. For a higher rate taxpayer the rate is 40%. For an additional rate taxpayer the Personal Savings Allowance is zero and the marginal rate is 45%.

At the July 2026 prize fund rate of 3.80% tax free, the equivalent before tax rate is 4.75% for a basic rate taxpayer, 6.33% for a higher rate taxpayer and 6.91% for an additional rate taxpayer. If you can find an easy access savings account paying more than the relevant equivalent rate, the savings account is mathematically the better choice.

Premium Bonds appeal more strongly to higher and additional rate taxpayers who have already used their cash ISA allowance and Personal Savings Allowance, and to savers who value the small chance of a large prize.

Tax treatment and ISA comparisons

All Premium Bonds prizes are paid free of UK income tax and capital gains tax. There is no tax to declare on prizes.

Cash ISAs also pay interest free of income tax inside the wrapper. The £20,000 annual ISA allowance covers contributions across cash, stocks and shares, innovative finance and Lifetime ISAs combined.

For most savers below the Personal Savings Allowance threshold the tax free status of Premium Bonds and cash ISAs is broadly equivalent in cash terms. Above the allowance, both keep you out of income tax on the savings.
