NS&I Rate Cut: How Chip's Prize Account Compares in 2026
NS&I has just announced Premium Bonds will drop to 3.30% with odds lengthening to 23,000:1 from the April 2026 draw. With over 22 million Premium Bonds holders reassessing their options, Chip's Prize Savings Account — which claims "3.5x better odds" — is getting renewed attention. But does the rate cut actually make Chip more attractive? We've run the updated numbers.
What Just Changed at NS&I
On 24 February 2026, NS&I announced a double blow for Premium Bonds holders. From the April draw:
- Prize fund rate: 3.60% → 3.30%
- Odds per £1 bond: 22,000:1 → 23,000:1
- Monthly prize fund: ~£408m → ~£375m
- Total prizes: ~6.18m → ~5.94m
This is the sixth cut since the prize fund rate peaked at 4.65% in September 2023. For the full breakdown of what it means for your Premium Bonds returns, see our detailed analysis of the April 2026 rate cut.
But with Premium Bonds becoming less generous, does Chip's Prize Savings Account now look like a better alternative? Let's examine what the rate cut actually means for the comparison.
Chip's "3.5x Better Odds" Claim: Now Outdated
Chip markets its Prize Savings Account with the headline claim of "over 3.5 times better odds than Premium Bonds." If you read the footnote on their website, you'll notice something interesting:
"Compared to the Chip Prize Savings Account January draw. Based on odds of winning any prize per £10 held with the Chip Prize Savings Account vs £10 held with NS&I Premium Bonds in September 2025."
That comparison used Premium Bonds odds of 22,000:1. With odds now lengthening to 23,000:1, we need to recalculate.
Updated Odds Comparison (April 2026 onwards)
| Product | Odds per £10 | Relative Advantage |
|---|---|---|
| Premium Bonds (new) | 1 in 2,300 | Baseline |
| Premium Bonds (old) | 1 in 2,200 | 4.5% better than new |
| Chip (avg. Jan-Sep 2025) | 1 in 964 | ~2.4x better |
| Chip (Sep 2025 only) | 1 in 623 | ~3.7x better |
Ironically, the Premium Bonds rate cut makes Chip's relative advantage slightly larger. Their "3.5x" claim, calculated against the old 22,000:1 odds, would now be closer to 3.7x against the new 23,000:1 odds — assuming Chip's own odds remain stable.
But here's the critical point that hasn't changed: better odds of winning doesn't mean better expected returns.
The Mean vs Median Problem: Now More Pronounced
The 3.30% prize fund rate is a mean average — skewed upward by rare large prizes including the two £1 million jackpots. Most Premium Bonds holders don't achieve anything close to 3.30%. This is the insight that competitors consistently miss and that we've been highlighting on PB Prizes since launch.
For a deep dive into this concept, see our median returns analysis. Here's the updated picture at the new rate:
Median vs Mean Returns at 3.30% (April 2026)
| Holding | Mean Return (3.30%) | Estimated Median | Gap |
|---|---|---|---|
| £50,000 | £1,650 | ~£1,400 (2.80%) | -15% |
| £25,000 | £825 | ~£650 (2.60%) | -21% |
| £10,000 | £330 | ~£225 (2.25%) | -32% |
| £1,000 | £33 | £0 | -100% |
The median return — what you'd expect with typical luck — is now around 2.80% for a maximum £50,000 holding. For smaller holders, the gap between headline rate and reality is even starker. With £1,000 or less, the most likely outcome over 12 months is still winning nothing at all.

Chip's Transparency Problem: Still Unresolved
Our original Chip vs Premium Bonds analysis highlighted a fundamental issue: Chip doesn't publish a prize fund rate equivalent. This makes accurate comparison impossible.
Premium Bonds publishes:
- Prize fund rate (3.30% from April)
- Exact odds (23,000:1 from April)
- Total bonds in circulation (~£120 billion)
- Complete prize distribution
- Historical data going back to 1957
Chip publishes:
- Historical odds (e.g., "1 in 964" average for Jan-Sep 2025)
- Monthly prize pools (which vary wildly)
- Winner testimonials
Chip doesn't publish:
- Total deposits in the Prize Savings Account
- An equivalent "prize fund rate"
- Any commitment to future prize levels
The Prize Pool Variance Problem
This is where Chip's comparison breaks down. Their monthly prize pools vary by up to 40 times:
| Month (2025-26) | Total Prize Pool | Grand Prize |
|---|---|---|
| November 2025 | ~£12,500 | £10,000 |
| December 2025 | £500,000 | £250,000 |
| January 2026 | ~£12,500 | £10,000 |
| February 2026 | ~£12,500 | £10,000 |
| March 2026 (quarterly) | £500,000 | £250,000 |
Premium Bonds, by contrast, pay out over £375 million every single month at a consistent rate. The prize pool is predictable, transparent, and doesn't depend on quarterly promotional campaigns.
Updated Expected Returns Comparison
Using our estimates from the original analysis (based on reverse-engineering Chip's published odds), here's how expected returns compare at the new Premium Bonds rate:
Expected Monthly Return: £1,000 Holding
| Product | Monthly Expected | Annual Expected |
|---|---|---|
| Premium Bonds (new 3.30%) | £2.75 | £33.00 |
| Premium Bonds (old 3.60%) | £3.00 | £36.00 |
| Chip (standard month) | ~£0.31 | N/A (varies) |
| Chip (quarterly month) | ~£12.50 | N/A (varies) |
| Chip (estimated annual avg.) | ~£1.60 - £2.80 | £19 - £34 (1.9% - 3.4%) |
Even at the reduced 3.30% rate, Premium Bonds' expected return appears to equal or exceed Chip's — and Premium Bonds' figure is guaranteed and published, while Chip's is our estimate based on limited data.
⚠️ Estimation Caveat
Chip's effective rate is our approximation based on published odds and prize pools. Chip does not publish actual deposit figures or an equivalent prize fund rate. If Chip has significantly more or fewer deposits than our estimates, their effective rate would differ proportionally.
Chip could resolve this ambiguity instantly by publishing their prize fund rate. The fact they choose not to is telling.
Protection and Security: An Unchanged Advantage
The rate cut doesn't change the fundamental security difference between the two products:
| Factor | Premium Bonds | Chip Prize Savings |
|---|---|---|
| Backing | 100% HM Treasury | ClearBank (FCA regulated) |
| Protection limit | Unlimited | £120,000 (FSCS) |
| Prize protection | Guaranteed from prize fund | NOT FSCS protected until withdrawn |
| Maximum holding | £50,000 | £85,000 |
| Withdrawal time | 3 working days | Near-instant |
That prize protection point bears repeating. Chip explicitly states: "Prizes are not FSCS eligible until they have been withdrawn back to your linked account."If Chip experienced financial difficulties before you withdrew a prize, that prize could be at risk.
Who Should Consider Chip After the Rate Cut?
The NS&I rate cut doesn't fundamentally change our recommendation from the original comparison. Chip may appeal to:
✅ Consider Chip If You:
- Have more than £50,000 to save (Chip allows up to £85k)
- Enjoy higher variance / the thrill of bigger potential prizes
- Prefer frequent small wins over rare larger ones
- Value instant access over 3-day withdrawals
- Are comfortable with fintech startup risk
- Want to take advantage of the March 2026 £500k quarterly draw
✅ Stick With Premium Bonds If You:
- Want predictable, published expected returns
- Value absolute security (HM Treasury backing)
- Prefer knowing exactly what prize rate you're getting
- Don't want returns dependent on promotional quarters
- Have £50,000 or less to save

The Bottom Line
The NS&I rate cut to 3.30% makes Premium Bonds less attractive than they were — but it doesn't fundamentally shift the comparison with Chip. Here's the summary:
- Chip's odds advantage increases slightly — from ~3.5x to ~3.7x against the new 23,000:1 odds
- Premium Bonds' median return drops — to approximately 2.80% for £50k holders (down from ~3.10%)
- Chip's transparency problem remains — no published prize fund rate, wildly variable monthly pools
- Security difference unchanged — unlimited Treasury backing vs FSCS limits and unprotected prizes
For most UK savers, Premium Bonds remain the more predictable, transparent choice — even at 3.30%. But if you're comfortable with higher variance and want to take a calculated punt on Chip's quarterly draws, depositing £10 for the March bonus entries is a reasonable gamble.
Just don't mistake "3.5x better odds" for "3.5x better returns." They're not the same thing.
Frequently Asked Questions
Is Chip's "3.5x better odds" claim still accurate?
It's actually become slightly more favourable since Premium Bonds odds lengthened to 23,000:1. However, Chip's marketing still references September 2025 data calculated against the old 22,000:1 odds. The real advantage is now closer to 3.7x for their best months.
Should I move my Premium Bonds to Chip?
Probably not as a wholesale switch. Premium Bonds offer published rates, unlimited government backing, and consistent monthly prizes. Chip offers higher variance with unpublished effective rates. Consider keeping the bulk in Premium Bonds and using a small Chip deposit to access quarterly bonus draws.
What's the deadline for the March 2026 Chip draw?
To get entries in the March 2026 £500k draw, you need an average balance of at least £10 in your Chip Prize Savings Account by 11:59pm on 31 March 2026. Depositing earlier in the month gets you more entries.
Are Chip prizes actually tax-free?
Chip states prizes are "tax-free" but includes the disclaimer: "Winners will be responsible for any individual tax liabilities." Premium Bonds prizes are explicitly tax-free under Treasury rules with no such caveat.
When will your calculator update with the new 3.30% rate?
We'll update all calculators and comparison tools with the new 3.30% rate and 23,000:1 odds when they take effect in April 2026. The March draw still uses the current 3.60% rate.
