How Each One Works
Premium Bonds replace interest with a monthly prize draw -- your money does not grow through a fixed rate, but every GBP 1 bond number is entered for a chance at prizes each month, funded by the pooled "interest" NS&I would otherwise pay across all bondholders.
A savings account pays a known interest rate on your balance, so your return is predictable and identical to any other saver with the same rate and balance -- there is no element of chance.
Worked Example: GBP 10,000 Held for 1 Year

| Premium Bonds (average holder) | Roughly matches prize rate, but many win less or nothing |
| Top easy access savings account | Guaranteed ~GBP 380-420 interest |
| Premium Bonds (unlucky holder) | GBP 0 in prizes for the year |
| Premium Bonds (lucky holder) | Could far exceed savings account return, up to GBP 1m jackpot |

Frequently Asked Questions
Frequently Asked Questions
How do Premium Bonds work?
No guaranteed interest -- every bond enters a monthly prize draw (GBP 25 up to GBP 1 million). The advertised "prize rate" is an average; any individual holder can win nothing or more than average.
What is the maximum I can hold?
GBP 50,000 per person, minimum GBP 25 purchase. Regular savings accounts have no such NS&I-style cap, though FSCS protection is limited to GBP 85,000 per provider.
Are prizes taxable?
No -- all Premium Bond prizes are completely tax-free and do not use your Personal Savings Allowance.
Show 7 more questionsShow fewer questions
Is a savings account guaranteed to grow my money?
Yes -- a known interest rate applies to your balance, giving certainty that Premium Bonds do not.
Which typically gives a better return?
A competitive savings account has historically offered a higher guaranteed return than the Premium Bonds prize rate for most holders, since many win nothing in a given month.
Can I lose money with Premium Bonds?
No -- capital is fully protected and always cashable at face value. The "cost" is opportunity cost from foregone guaranteed growth.
How fast can I access the money?
Premium Bonds cash-in typically takes a few working days; easy access savings accounts are often same-day or instant via a linked current account.
Do Premium Bonds suit higher/additional-rate taxpayers?
Relatively well, since prizes are tax-free -- useful for those with little or no Personal Savings Allowance left. A Cash ISA is also worth comparing.
Do all holders have equal winning odds?
Each GBP 1 bond has equal odds each month, so overall chances scale with holdings up to GBP 50,000 -- but no outcome is guaranteed.
Which suits a risk-averse saver?
A savings account or Cash ISA, for predictable guaranteed growth. Premium Bonds suit those comfortable with variable, possibly zero, returns for a tax-free prize chance.
