ToolsInflation impact calculator
Inflation is a percentage until you apply it to your own savings. Enter an amount, your country's inflation rate and a horizon to see what that money will actually buy — and how many years it takes for its purchasing power to halve.
What it will buy then
4,631.9
Purchasing power lost: 5,368.1
Years to halve
9
At this rate, money that just sits loses half its purchasing power in this many years.
Assumes a constant rate. Real inflation moves year to year, and the rate you experience depends on what you buy — this shows the mechanism.
How this calculator works
Inflation compounds like interest, but against you. At a steady rate i, money loses value by 1/(1+i) each year; the calculator applies that over your horizon and shows what today's amount will actually buy. It also computes the halving time — roughly 72 divided by the rate — the single most intuitive way to feel what a percentage means.
A worked example
$1,000 under 10% inflation: after 10 years it buys what $386 buys today — it lost 61% of its purchasing power while the number on the account never changed. The halving time at 10% is about 7 years; at 3%, about 24 years. That difference is why the same savings habit produces such different lives in different countries.
Common questions
- The official inflation rate feels lower than my real cost of living. Why?
- Official CPI averages a national basket of goods; your basket — your rent, your food, your school fees — can inflate much faster. It also averages the year, while you feel the jumps. For planning, run the tool at both the official rate and your honest personal estimate.
- How do people protect savings from high inflation?
- By holding less of the melting asset: assets that historically outrun inflation (broad stock indexes, property), hard assets like gold, or — where local currency is the problem — foreign-currency or stablecoin balances. Each carries its own risks; the why-currencies-lose-value article walks through the trade-offs without prescribing one.
- Is any inflation actually normal?
- Most central banks deliberately target about 2% — mild, predictable inflation greases wage adjustments and discourages hoarding cash. The damage comes from high or volatile inflation, where planning breaks down and savings melt faster than wages adjust.
What this tool can't tell you
The tool assumes one steady rate, and real inflation arrives in surges. It also measures only purchasing power — not what your savings could have earned invested (the compound-growth tool shows that side). Together they frame the real question: growth rate versus erosion rate.
