  • Inflation, plainly explained

Money doesn't shrink.
Its buying power does.

A dollar sitting still today buys less than it did a decade ago — quietly, every year, whether you notice or not. This isn’t a sales pitch. It’s the math behind why “saving” isn’t the same as “keeping up.”

Most people track their income closely and their purchasing power not at all. This page walks through the difference, using ordinary prices and a plain-language guide you can actually use — no jargon, no pressure, no one calling you afterward.

  • Ten years, five checkpoints

What the same basket of goods cost, then and now.

Prices don’t move in a straight line, but the direction rarely reverses. Here’s a rough sketch of one everyday item over the last decade — the kind of number that doesn’t show up on a bank statement, but adds up in a grocery bill.

None of these numbers are dramatic on their own. That’s exactly the point — inflation rarely announces itself. It shows up as a slightly higher total at checkout, a slightly smaller grocery bag for the same amount of money, a raise that somehow doesn’t feel like one.

The same pattern shows up almost everywhere you look: rent, insurance, a haircut, a cup of coffee. Individually, each increase is easy to shrug off. Stacked across a decade, they explain why a salary that looks unchanged on paper can feel like it stretches less every year.

Do you know how much your money is really worth today compared to ten years ago?

If you had £100,000 sitting in the bank back then, it would only buy about £80,000 worth of goods today — that’s a 20% loss in real value due to inflation.

Now, while bank savings accounts paid less than 1% interest per year, inflation averaged around 2.5–3%, meaning your money was silently losing value year after year.

But here’s the real kicker — during that same decade, the Nasdaq 100 index grew by almost 400%.
In other words, money invested in the market didn’t just hold its value — it multiplied nearly five times.

And while most people trusted their banks to ‘keep their money safe’, the banks and professional traders were using that very same money to make those returns for themselves.

Enquanto seu dinheiro está parado, alguém o está fazendo render — para si próprio.
It’s time to take control and make your money work for you instead.

The two-minute explainer

A short, plain-language walkthrough of how purchasing power is calculated and why it matters more than the number on your pay stub. No hosts trying to sell you anything at the end — just a clear explanation you can rewatch whenever the numbers start to blur together.

~3%

Average annual U.S. inflation rate over the past 10 years, compounding quietly year over year rather than arriving all at once.

26%

Roughly how much more the same basket of everyday goods costs today versus a decade ago, based on typical household spending.

People who say, in informal surveys, that they’ve never actually sat down and calculated their own purchasing-power change.
  • Why it matters

Four places this shows up in real decisions.

Purchasing power isn’t an abstract economics term. It shows up directly in ordinary choices about where money sits and what it’s expected to do.

01

Cash savings

Money sitting in a low-yield account isn’t “safe” in the way it feels — it’s simply losing value more slowly than spending it would. The balance stays the same; what it can buy doesn’t.

02

Salary negotiations

A raise that matches inflation isn’t really a raise — it’s a way of standing still. Knowing the real number changes how a cost-of-living conversation should go.

03

Long-term goals

A retirement number set ten years ago, and never adjusted, is probably already out of date. Purchasing power is one of the few variables worth re-checking on a schedule.

04

Evaluating any pitch

Any offer promising to “beat inflation” only means something once you know what inflation has actually been. That’s the baseline everything else should be measured against.
  • What readers say

Mostly, people say the same thing: "I wish I'd checked this sooner."

I always knew inflation was “a thing,” but seeing my actual number made me finally move some cash out of a checking account that was paying nothing.
John – Software Engineer
Used the worksheet before a salary conversation. Having the real number, not a guess, made the whole discussion feel less awkward.
Olivia – Marketing Consultant
Short, no upsell, explained clearly. I’ve sent the video to two people who kept asking me why prices “feel” so much higher than the news says.

  • How it's calculated

Three steps, no black box.

Nothing on this page relies on a proprietary model. It’s the same basic method used throughout personal finance, just applied to your own numbers instead of a national average.

01

Start with an amount and a time period

Pick a dollar figure — savings, salary, or a price you pay regularly — and the number of years you want to look back or project forward.

02

Apply an average annual inflation rate

The rate compounds year over year rather than applying once, which is why small annual increases add up to a much larger change over a decade.

03

Compare the result to today's dollars

The output tells you what the original amount would actually buy — its real, adjusted value — rather than its unchanged face value.
