Key takeaways
The premium bonds annual prize fund rate for 2026 is set by NS&I and reviewed periodically. The current rate and prize distribution are published at nsandi.com.
The prize fund rate is an equivalent annual return across all bonds in the draw -- it does not mean every holder earns that rate. Individual returns depend entirely on whether your bonds are randomly selected to win.
Prizes range from 25 pounds to two jackpots of 1 million pounds each month. There are also prizes of 100,000, 50,000, 25,000, 10,000, 5,000, 1,000, 500 and 100 pounds.
The odds of any individual 1 pound bond winning a prize in a given month are published by NS&I each draw. As of early 2026, the odds are approximately 1 in 22,000 per bond per month.
All prizes are tax-free. The prize fund rate is not a guaranteed return -- in any given year a holder could win nothing or win multiple prizes.

How the prize fund rate works
NS&I sets a prize fund rate -- expressed as an annual percentage -- which determines the total amount allocated to prizes each month across all bonds in issue. If 125 billion pounds of bonds are held and the prize fund rate is 4%, NS&I allocates approximately 500 million pounds per year in prizes, or roughly 41 million pounds per month.
This total is then distributed across prize bands according to NS&I's published prize band structure. The majority of prizes by number are at the lower end (25 and 50 pound prizes), while a small number of higher-value prizes make up a large proportion of the total prize fund value.
Prize band distribution
Each month NS&I publishes the prize breakdown showing how many prizes fall into each band. The two 1 million pound jackpots are always awarded. Below the jackpot level, the number of prizes in each band scales with the total prize fund size.
Higher-value prizes (100,000 pounds and above) are fewer in number but carry significant weight in the total prize fund. Lower-value prizes (25 and 50 pounds) are awarded in far greater numbers -- the majority of winners each month receive these amounts.
Odds of winning
NS&I publishes the odds of winning for any individual 1 pound bond in a given monthly draw. As of early 2026, the odds are approximately 1 in 22,000 per bond per month. This means that a holder with the maximum 50,000 pounds in bonds statistically expects to win approximately 2 to 3 prizes per month on average -- though actual results vary because each bond is selected independently at random.
A holder with the minimum 25 pounds in bonds (25 individual bonds) has a much lower statistical probability of winning in any given month. Over a year they might expect to win once or twice, though random chance means some years produce no wins and others produce multiple.
How NS&I sets and changes the prize fund rate
NS&I reviews the prize fund rate periodically and adjusts it in line with broader interest rate movements and government savings policy. When the Bank of England base rate rises significantly, NS&I typically increases the prize fund rate to maintain the attractiveness of premium bonds relative to savings accounts. When rates fall, NS&I may reduce the prize fund rate.
NS&I announces rate changes in advance and publishes them at nsandi.com. The rate change takes effect from a specified draw date. NS&I is required to act in a way that is fair to savers while also not distorting the broader savings market -- this means its rates broadly track the market but with some lag.
Prize fund rate vs equivalent savings rate
The prize fund rate is not the same as a guaranteed savings rate. A 4% prize fund rate does not mean every holder earns 4% per year. It means the total pot of prizes equals 4% of the total bonds in issue. An individual holder's actual return depends entirely on random chance.
For holders with large holdings (closer to the 50,000 pound maximum) the law of large numbers means actual returns over several years tend to approach the prize fund rate. For holders with small amounts the variance is much higher -- they may earn significantly more or less than the equivalent rate in any given period.
