How Much Interest Does £1 Million Earn in the UK? (Monthly & Yearly)
Do you have £1 million tucked away? Or are you just idly wondering what life would look like if you ever did? Either way, the question most people ask is simple: how much interest would £1 million actually earn you in the UK?
The honest answer is: anywhere from £10,000 to £100,000 per year, depending on how your money is stored, invested, and taxed.
How Much Interest Does £1 Million Earn in the UK?
If you had £1 million sitting in the bank, how much interest would it actually earn you?
The honest answer is: probably less than you expect on cash — and far more if you’re willing to invest.
Most people assume that having a large balance unlocks better savings rates. In reality, the opposite is usually true. High-interest accounts often cap balances, and large sums quietly earn lower rates once bonuses expire.
What Would £1 Million Earn in a Savings Account?
On a conservative 1–3% savings rate, £1,000,000 would earn roughly:
£10,000–£30,000 per year
£833–£2,500 per month
That’s before tax.
For context, the Bank of England base rate is currently 3.75%, but this is not what banks pay savers — especially on very large balances.
What About Higher Returns?
If you could achieve a 4% return, £1,000,000 would generate:
£40,000 per year
£3,333 per month
£769 per week
This level of return is more realistic through investing or carefully structured accounts, rather than a single easy-access savings account.
What Is the Monthly Interest on £1 Million?
This is what people really want to know.
Here’s how £1 million breaks down at different interest rates:
Interest rate | Monthly interest | Yearly interest |
|---|---|---|
1% | £833 | £10,000 |
2.5% | £2,083 | £25,000 |
3.75% | £3,125 | £37,500 |
5% | £4,167 | £50,000 |
7% | £5,833 | £70,000 |
10% | £8,333 | £100,000 |
Cash savings usually sit at the lower end of this table. The higher figures require investment risk.

Could You Live Off the Interest From £1 Million?
Sometimes. Not always.
At 1–2.5%, no — unless you already own your home outright and live very frugally.
At 4–5%, yes — for many people, especially outside London.
At 7%+, comfortably — but now you’re fully in investment territory, with market swings and risk.
A million pounds is life-changing money, but it’s not “never think about money again” wealth unless it’s managed properly.
Where Should You Put £1 Million?
This is where expectations often clash with reality.
Cash savings
Safe, boring, predictable — and usually low-yielding. Large balances often receive poorer rates than headline offers.
Important: the FSCS only protects £85,000 per banking institution. A £1m saver would need money split across multiple banks to be fully protected.
Property
Can deliver solid long-term returns, but it’s rarely passive unless you pay for management, which eats into yield quickly.
Stocks and shares
Higher long-term return potential, higher risk. Personally, my own Stocks & Shares ISA has averaged around 8% per year, but that includes ups, downs, and patience.
Anyone promising high returns with no risk should be avoided.

Best Interest Rate on £1 Million: The Reality
This is the bit comparison sites gloss over.
• Savings accounts have balance caps
• Bonus rates expire
• “Best rates” often apply to small balances only
• Inflation quietly erodes cash returns
For large sums, returns usually come from a mix of cash, investments, and tax planning, not a single magic account.
How Much Interest Would £2m, £5m, £10m or £20m Earn?
At a 4% return, here’s what bigger sums look like:
Amount | Yearly interest | Monthly interest |
|---|---|---|
£1m | £40,000 | £3,333 |
£2m | £80,000 | £6,667 |
£5m | £200,000 | £16,667 |
£10m | £400,000 | £33,333 |
£20m | £800,000 | £66,667 |
Would £1 Million Be Enough for Retirement?
For most people, yes — if spending is sensible.
A £1m pot producing £40k–£50k per year can support a very comfortable retirement, particularly once housing costs fall away. It won’t fund yachts and private jets, but it does fund freedom.
Don’t Forget the Tax
Interest is income.
Outside ISAs and Premium Bonds:
• Basic-rate tax: 20%
• Higher-rate tax: 40%
• Additional-rate tax: 45%
On £40,000 of interest, tax can easily remove £8,000–£18,000 unless your money is properly sheltered.
How Do You Actually Get to £1 Million?
Almost nobody gets there overnight.
It’s boring, consistent investing, time, and compound interest doing the heavy lifting. I’ve written a full guide explaining how ordinary earners can realistically become millionaires without lottery tickets or risky schemes.
