What are my chances of winning the draw?

On average, a person holding an NS&I bond will get a return of 1.15% - meaning if you haveaverage luck, you're likely to win prizes worth around 1.15% of your investment.

As of May 2017, the NS&I awards2,224,513 prizes every month. Of these,2,076,942 are worth the lowest prize band of £25.

Two winners each month are awarded the £1m jackpot, while another three take home £100,000. Winners are chosen at random by the NS&I's random number generating computer, known as ERNIE, and all winnings are tax-free.

How can I improve my odds of winning?

The odds of any particular bond number winning a prize each month are 30,000 to one. But themore bonds you buy, the better your chances of winning. To have a decent shot at a prize over the course of a year,you'll need at least £1,000 worth of bonds.

Once you invest £10,000 (or take out 10,000 bonds), your chances of winning at least one prize become a near-certainty. But keep in mind your winnings could be low as £25, meaning a return of just 0.25% - well below the interest on an ordinary savings account.

Premium bonds come with a slim chance of striking it rich - but returns are not guaranteed. If you want to make a regular income from your savings, you'd be better off holding your money in a savings account or Isa.

How dopremium bonds work?

The Government-backed lottery bond, founded by Prime Minister Harold Macmillan in 1956, is the UK's favourite savings account. Savers buy bonds which are then entered into a monthly prize draw.

These are then bought back by the government for their original price, plus an annual prize interest rate of 1.15%. All prizes are tax free and there are no penalties for withdrawals. To be in with a chance of winning you need to save between £100 and £50,000.
