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
- Choose Premium Bonds as the account type. The provider is set to NS&I automatically, because that's the only place they're offered.
- Enter how much you hold. The minimum is £25 and the maximum is £50,000 per person.
- 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.
- 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.
