Your inflation
The official rate follows the prices of the average household’s shopping. Put in what you spend in a month, and see the rate for yours.
How it works
Statistics offices measure inflation with a basket: the things the average household buys, each with its share of the budget. Your basket is different. If more of your money goes on the things whose prices rose most, your inflation is higher than the official rate.
The calculator takes the price change of each category over the last 12 months, as the statistics office published it, and weights it by your share of spending instead of the average household’s. On the receipt, your share times the price change gives each line’s part of your rate.
The official index is built month by month, so a simple sum of its categories misses the published rate by a little. The adjustment line adds that gap back. It is the same for everyone in a country, and it makes the average household’s receipt end on the official rate.
The categories are broad. Inside transport, fuel may have risen while cars got cheaper, and the calculator cannot see which of them you buy. Take the result as an estimate.
Nothing you type leaves your browser. The link you copy holds your amounts, so anyone who opens it sees the same receipt.
