See what today's money may need to equal in the future and how an unchanged amount loses purchasing power.
Read the same change as a future cost and as purchasing power.
The amount needed to buy the same thing if prices follow your assumption.
What the unchanged amount would be worth in today's money.
Future cost minus today's amount.
The compounded price change over the whole period.
Think in real terms
Compare with the savings calculator and separate nominal returns from purchasing-power growth.
Your basket is personal
Use the household budget to identify the prices that matter most to you.
Leave room in long plans
Test retirement plans with both cautious returns and higher inflation.
How is inflation calculated?
The amount is multiplied by (1 + annual inflation) to the power of the number of years. Purchasing power uses the inverse.
Can inflation be negative?
Yes. A broad fall in prices is deflation. Negative scenarios are supported, although long-term plans should not rely on continuing price falls.
Which rate should I use?
Use a central assumption and test higher and lower cases. For Sweden, the Riksbank's inflation target is 2 percent measured by CPIF, but actual inflation varies.
Is this a forecast?
No. It is a constant-rate scenario, not a prediction of future prices.
Two percent a year adds up to more than 20 percent over ten years because each increase builds on the previous price.
Official indices follow a broad basket. Your experience depends on how much you spend on housing, food, transport, and other categories.
Future inflation is uncertain. Compare several rates when planning savings, retirement, or a household budget.
Enter an amount in today's money, choose an average annual inflation rate, and set the number of years. The calculator shows both the future cost of the same purchase and the future purchasing power of an unchanged amount. These are two views of the same price movement. Try a grocery budget, a regular household expense, or a savings target rather than an abstract number.
Inflation compounds. A price of 10,000 becomes 10,200 after one year at 2 percent, and the next increase applies to 10,200. After ten years the equivalent cost is about 12,190, a cumulative increase of roughly 21.9 percent. The same compounding that helps investments can work against cash that does not grow.
Consumer price indices follow a broad basket of goods and services. Sweden's Riksbank targets 2 percent inflation measured by CPIF, but actual inflation varies over time. Your household may also feel a different rate depending on how much goes to housing, food, electricity, or transport. That is why this tool accepts your own assumption instead of presenting one forecast as fact.
No one knows the average rate for the next decade. Compare a central case with higher and lower alternatives. When planning savings, look at returns after fees, tax, and inflation. For retirement or a household budget, include an uncomfortable case as well. This result is a constant-rate scenario, not a promise about future prices.
