The burger that explains everything
In 1972, McDonald's launched the Quarter Pounder. It sold for $0.53. Same beef patty, same sesame seed bun, same two pickles. Nothing fancy.
Here's what happened to its price over the next five decades:
| Year | Price | vs. 1972 |
|---|---|---|
| 1972 (launch) | $0.53 | — |
| 1990 | $1.57 | +3× |
| 2000 | $2.49 | +5× |
| 2010 | $3.59 | +7× |
| 2020 | $4.79 | +9× |
| 2024 | $7.29+ | +14× |
Same patty. Same bun. Same pickles. 14 times the price. Nobody cheated you — that's just what inflation looks like over a lifetime.
This isn't just a fast food story. The same thing happened to your rent, your energy bill, your weekly shop, your car insurance. Everything costs more. And it didn't happen overnight — it crept up year by year, so quietly you barely noticed until you did.
So what actually is inflation?
Inflation is what happens when prices across the whole economy rise over time. It's not one shop being greedy. It's not one bad year. It's a slow, steady, completely normal part of how money works — and it averages around 3% per year in most developed countries.
Here's the plain-English version: imagine a candy bar costs £1 today. Next year, the same candy bar costs £1.10. Your £1 didn't vanish. The bar didn't get bigger. But your £1 can now only buy part of it. That 10p gap is inflation doing its thing.
The technical term is "buying power" — what your money can actually buy. When prices go up and your money stays the same, your buying power quietly goes down. It's the same result as losing money, just slower and less obvious.
And here's the part most people miss: this happens even when you're not spending anything. Your savings sitting in a jar, a current account, or under the mattress — they're losing ground every single year. Not because you did something wrong, but because you didn't do anything at all.
What happens to £100 if you just leave it alone
You don't have to spend a penny. You just have to do nothing — and inflation still wins.
Say you tuck £100 away today and leave it there. Inflation runs at around 3% per year — pretty normal. Here's what happens to the buying power of that £100:
| Year | Your £100 buys… | Value lost |
|---|---|---|
| Now | £100.00 | — |
| +1 year | £97.09 | −£2.91 |
| +3 years | £91.51 | −£8.49 |
| +5 years | £86.26 | −£13.74 |
| +10 years | £74.41 | −£25.59 |
You didn't spend a penny. You didn't make one mistake. You just left it alone — and inflation quietly wiped out over a quarter of its value.
Your £100 still says £100. But 10 years later, it only buys what £74 used to buy. That's not okay. But it is fixable.
Three moves that keep you ahead
The good news: inflation is predictable. It moves slowly, in one direction, year after year. That makes it beatable. Think of the three moves below as a risk ladder — start at the bottom, and climb as you get comfortable.
The simplest way to know which move is right for each pound you have is to ask one question: when will I need this money?
- Money you might need tomorrow → savings account (Move 1)
- Money you won't need for 1–3 years → bonds (Move 2)
- Money you can leave alone for 5–10+ years → ETFs (Move 3)
| Move | Expected return | Best for… | Effort to start |
|---|---|---|---|
| 01 — Savings account | 3–5% | Emergencies & rainy days | 10 mins |
| 02 — Bonds | 4–6% | 1–3 year goals | 15 mins |
| 03 — Global index ETF | 7–10% | Retirement & wealth | 20 mins |
Move 1: Find a bank that pays you interest
Most people park their savings in a standard current account. The bank gives them around 0.1% interest and quietly reinvests your money at far higher rates. Against 3% inflation, you're losing ground every single year — and most people never notice.
The first move is simple: switch to an account that actually pays you interest. Many banks and neobanks now offer 3–5% on easy-access savings accounts. That's your first line of defence — and crucially, it's also your emergency fund. Three to six months of expenses, earning interest, accessible any time.
"~0.1% interest per year"
"3–5% interest per year"
Pro: Full liquidity — you can access it any time. Doubles as your safety net for unexpected expenses. Con: You're still technically slightly behind inflation in some periods, but in practice it's barely noticeable — and far better than doing nothing.
🔒 Your money is protected. In the UK, cash held in authorized bank accounts is protected up to £85,000 per bank by the FSCS (Financial Services Compensation Scheme). In the US, the equivalent is FDIC protection up to $250,000. For most people, that's more than enough of a safety net.
Move 2: Bonds — low risk, beating inflation
Once you have your emergency fund sorted, it's time to put the rest of your savings to work. This is where bonds come in — and they're much simpler than they sound.
A bond is basically a loan you make to a government or a company. In return, they pay you a fixed interest rate — typically 4–6% per year. That's above inflation. Your money is growing in real terms, not just keeping pace.
The good news: you don't need a stockbroker or a finance degree to access bonds anymore. Most modern neobanks — Revolut, Trading 212, Lightyear and others — now let you invest in government and corporate bond funds directly from your phone, in minutes.
"3–5% — safe, liquid, accessible"
"4–6% — low risk, beats inflation"
💡 The "Real Return" reality check. If inflation is running at 3% and your bond pays 5%, your real return is 2%. That's the actual profit — the genuine increase in what you can buy. A savings account at 3.5% against 3% inflation? Your real return is just 0.5%. Bonds at 5%? That 2% real return is money that's genuinely working for you.
Pro: Returns that genuinely beat inflation with minimal stress — government bonds are about as safe as it gets. Con: Your money is less liquid than a savings account. Best for funds you won't need for at least a year.
Government bonds are backed by the state. Corporate bonds by established companies. Neither is a get-rich-quick scheme — they're a steady, reliable way to make your money work harder than a savings account.
Move 3: ETFs & Stocks — long-term wealth
This is the most powerful move — and the one most people put off because it sounds complicated. It isn't.
An ETF (Exchange Traded Fund) is a basket of hundreds of companies bundled into one investment. When you buy a global index ETF — like one tracking the MSCI World or the S&P 500 — you're investing in the world's biggest companies all at once. Apple. Microsoft. Amazon. Nestlé. Samsung. Hundreds of them, in a single purchase. No stock picking. No guessing. Just broad, diversified growth.
Historically, a simple global index ETF has returned around 7–10% per year over the long run. That doesn't just beat inflation — it laps it. But the magic isn't just the percentage. It's what happens when returns compound year after year.
But what about crashes? Yes — markets go up and down. There will be bad years. The key insight is that every single crash in the history of the global economy has eventually recovered and reached new highs. The 2008 financial crisis. The 2020 COVID crash. Both fully recovered within a few years. Time is your shield. The longer you stay invested, the less any individual crash matters.
Imagine you plant one apple seed in your garden. That seed grows into a tree. The tree drops ten more seeds. You plant those. Now you have ten trees. Each of those drops ten seeds. Suddenly you have a hundred trees. Then a thousand. You planted one seed — but now you have a forest. That's compounding.
Here's what £20 a month actually does, invested in a global index ETF at a 7% annual return — roughly the historical long-run average:
You put in £4,800 over 20 years. The ETF's compound returns grew another £5,624 on top — for free.
Inflation erodes idle money. But it can't touch a growing forest. A simple index ETF, left alone for 10–20 years, doesn't just beat inflation — it builds the kind of wealth that changes your life. You don't beat rising prices by hiding from them. You beat them by growing.
Pro: The highest long-term returns of the three moves — historically 7–10%/year. Con: More short-term volatility than bonds. Best for money you can leave untouched for 5+ years.
The risk ladder — start at the bottom
You don't have to do all three at once. The whole point of the ladder is that each step builds on the last. Most people start at Move 1 and stay there for years — and that's completely fine.
Here's the order that makes sense for most people:
- Build your emergency fund in an interest-bearing savings account. 3–6 months of expenses, accessible, earning 3–5%.
- Move extra savings into a bond fund. 4–6% return, low risk, inflation-beating. Good for money you won't need for a year or more.
- Start investing in a global index ETF — even £20/month. The earlier you start, the more time compounding has to work.
Inflation is powered by time — the longer you wait, the more ground it takes. The most important thing isn't the amount. It isn't picking the perfect product. It's simply choosing to start.
