Premium Bonds vs Lottery: Comparing the Odds and Expected Returns
Both Premium Bonds and the National Lottery offer the dream of winning big. But how do the odds actually compare? And which offers better value for your money? Let's break down the mathematics.

The Fundamental Difference
Before diving into odds, it's crucial to understand the fundamental difference between these two products:
Premium Bonds: You Keep Your Stake
When you buy Premium Bonds, your money remains yours. You can cash out at any time and get back exactly what you put in. The "gambling" element comes from potentially winning prizes instead of earning guaranteed interest.
Lottery: Your Stake Is Gone
When you buy a lottery ticket, that money is spent. Whether you win or lose, the ticket cost is gone forever. Only about 50% of ticket sales are returned to players as prizes.
This is why direct odds comparisons can be misleading - you're comparing an investment (with variable returns) to gambling (with expected losses).
Odds Comparison: Premium Bonds vs National Lottery
| Prize Type | Premium Bonds (per £1 bond/month) | National Lottery Lotto (per £2 ticket) |
|---|---|---|
| Any prize | 1 in 22,000 | 1 in 45 |
| £25-£50 | 1 in 22,477 | 1 in 97 (£30 prize) |
| £100 | 1 in 773,856 | 1 in 2,180 (Match 4) |
| £1,000 | 1 in 1.85 million | 1 in 144,415 (Match 5) |
| £100,000 | 1 in 4.6 billion | 1 in 7.5 million (Match 5 + Bonus) |
| Jackpot | 1 in 56 billion (£1m) | 1 in 45 million (£2m+ rollover) |
Looking at raw odds, the lottery appears to offer much better chances of winning any individual prize. But this misses three crucial points:
- Premium Bonds enter every month, automatically. That £1 bond gets 22,000:1 odds every single month, forever, as long as you hold it.
- You can cash out Premium Bonds. Unlike a lottery ticket, your Premium Bonds stake never disappears.
- More bonds = more chances. With £1,000 in Premium Bonds, you have 1,000 chances each month. You'd need to buy 1,000 lottery tickets (£2,000) to match that frequency.
Expected Return: The Real Comparison
Expected return is what matters for long-term value. It's what you can expect to get back for every pound you put in.
| Product | Expected Return | What This Means |
|---|---|---|
| Premium Bonds | 100% (capital) + 3.6% (prizes) | You keep everything plus average 3.6% annually |
| National Lottery Lotto | ~47% of ticket price | On average, lose 53p of every £1 spent |
| EuroMillions | ~50% of ticket price | On average, lose 50p of every £1 spent |
| Scratch Cards | ~60% of ticket price | On average, lose 40p of every £1 spent |
💡 The £100/Month Comparison
If you spent £100 per month on lottery tickets for 10 years, you'd spend £12,000 and statistically expect to get back roughly £5,700 in prizes (losing £6,300).
If you put £100 per month into Premium Bonds for 10 years, you'd have £12,000 in bonds plus an average of around £2,200 in tax-free prizes (total ~£14,200). And you can withdraw the £12,000 any time.
The Jackpot Question
Here's where the lottery has an undeniable advantage: the size of potential wins. Premium Bonds cap out at £1 million (with two prizes per month), while EuroMillions jackpots can exceed £100 million.
If your goal is a genuinely life-changing, multi-generational wealth event, the lottery is the only option. The odds are astronomical (1 in 139 million for EuroMillions), but the prize is correspondingly enormous.
However, most "life-changing" amounts are actually achievable through Premium Bonds at much better odds:
| Life Goal | Amount Needed | Premium Bonds Route |
|---|---|---|
| Pay off credit card debt | £5,000-£10,000 | Save it directly + win prizes |
| House deposit | £25,000-£50,000 | Save it directly + win prizes |
| Clear mortgage early | £50,000-£100,000 | Max Premium Bonds odds: 1 in 2,000/month for £100k win |
| Retire early | £500,000+ | Need lottery odds territory |
Which Is Better for You?
Choose Premium Bonds if:
- You want to save money while having some excitement
- You're disciplined and would otherwise spend lottery money
- You want the "lottery feeling" without the guaranteed loss
- You're happy with the chance of winning up to £1 million
- You want tax-free returns with zero risk to your capital
The lottery might suit you if:
- You spend small amounts purely for entertainment (and can afford to lose it)
- You dream specifically of enormous jackpots (£10m+)
- You understand and accept the negative expected return
- It's a social activity (office pools, etc.) rather than serious investing
The Hybrid Approach
Many people do both: Premium Bonds for their serious savings (capturing the prize excitement while keeping their money safe), and occasional lottery tickets purely for the entertainment of dreaming about huge wins. The key is keeping lottery spending to entertainment-budget levels, not savings levels.

Frequently Asked Questions
What are my monthly odds of winning anything with £10,000 in Premium Bonds?
With £10,000 in Premium Bonds (10,000 bonds), you have roughly a 36% chance of winning at least one prize each month. Most winners at this level win 1-2 prizes of £25 per month on average, though results vary significantly.
Has anyone won £1 million with a small holding?
Yes! NS&I regularly announces £1 million winners who hold less than the maximum. In January 2024, a winner held just £37,000. However, statistically, larger holdings win more often simply due to having more bonds in the draw.
Are Premium Bonds gambling?
Technically no - gambling requires the possibility of losing your stake. With Premium Bonds, you always keep your capital. The Financial Conduct Authority classifies them as savings products, not gambling. However, they do have gambling-like psychological elements (anticipation, variable rewards), which some find engaging and others find frustrating.
Should I stop buying lottery tickets and put it in Premium Bonds instead?
Mathematically, yes - you'll almost certainly be better off financially. But this is a personal choice. If lottery tickets bring you genuine entertainment value worth the cost, and you can afford it, that's your decision. Just be honest about the odds.
