How to track Premium Bonds

Record your NS&I Premium Bonds in Oinkly, log your prize wins, and understand how the average prize rate and FSCS-free protection work.

Premium Bonds don't pay interest — instead you're entered into a monthly prize draw. Because they behave differently from a savings account, Oinkly gives them their own account type so the figures stay honest.

Adding your bonds

  1. Choose Premium Bonds as the account type. The provider is set to NS&I automatically, because that's the only place they're offered.
  2. Enter how much you hold. The minimum is £25 and the maximum is £50,000 per person.
  3. Add the date of purchase. Bonds only enter the draw after a full calendar month, so a brand-new holding won't win straight away.
  4. Optionally add your holder's number — it doesn't affect anything, it just helps you match your records to NS&I.

Recording wins

When you win, add a Winnings entry to keep the running total accurate. Prizes are completely tax-free, so they don't count towards your Personal Savings Allowance.

Understanding the returns

The headline prize fund rate (3.80% for the July 2026 draw) is an average across everyone who holds bonds, not a guaranteed return for you. Because a few large prizes lift that average, most people with typical holdings earn a little less than the headline figure — and it evens out the more bonds you hold. The odds are around 22,000 to 1 for each £1 bond, each month.

Good to know

Premium Bonds are held with NS&I, which is backed 100% by HM Treasury. That means they sit outside the FSCS limit entirely — your money there is fully protected however much you hold, unlike deposits at an ordinary bank.
