Premium bonds
The returns on Premium Bonds are highly variable because they depend on random prize draws rather than guaranteed interest. Here’s a breakdown to help you understand how this works:
1. Expected Return
• Prize Fund Rate (4.65%): This is the average “interest rate” across all bondholders, assuming prizes are distributed evenly. • In reality, only some people win prizes, and others may win nothing at all. The variability means your personal return could be much higher or much lower than 4.65%.
2. Distribution of Prizes
Premium Bonds prizes are skewed:
• Most prizes are small (£25).
• There are far fewer medium (£1,000, £5,000) and large (£1 million) prizes.
• For each £1 million jackpot, there are millions of £25 prizes distributed.
This skew means:
• You’re most likely to win £25 if you win at all.
• Large prizes are extremely rare, even for large holdings.
3. Likelihood of Winning Over Time
• With £22,000, you can expect to win approximately one £25 prize per month on average, but:• In some months, you may win nothing.
• In other months, you may win multiple £25 prizes or, rarely, a larger prize.
• With the maximum holding (£50,000), you’re more likely to win 2 or 3 £25 prizes per month on average, but it’s still random.
4. Simulation of Returns
Here’s an example of variability: • £22,000 invested for a year: • Some people may win £300-£400 in £25 prizes (consistent with 4.65%).
• Others may win significantly more or less due to luck.
• £50,000 invested for a year: • Some people may win £1,000-£2,000.
• Others could win far less or even hit a rare big prize (e.g., £1,000 or £1 million).
5. Is it Worth It?
• For Regular Returns: Premium Bonds are not guaranteed to provide a steady income. Variability means some years you might see very little return.
• For Safety: Your money is safe with NS&I, and you can withdraw it anytime.
• For Fun: Premium Bonds are essentially a “safe gamble” — they’re more enjoyable if you view prizes as a bonus rather than relying on regular returns.
