📌 How We Handle Inflation Rates at iCalculator

At iCalculator, we strive to use the most accurate, up-to-date, and officially published annual inflation rates available from trusted statistical offices and global financial institutions. For the majority of years, including those in our historical inflation datasets, this means referencing the exact figures released by a country’s government or central bank.

However, in some instances official annual figures may not yet be published or accessible. In these cases, we use reliable economic indicators like composite business climate indices, exchange trends, or fiscal performance signals to provide an estimated benchmark rate. These figures help ensure that our tax and finance calculators maintain relevance and directional accuracy during periods of economic transition or delay in official data.

⚠️ Disclaimer

The inflation rate estimates provided are for informational and directional purposes only. While we use robust analytical methods and verified indicators, users are encouraged to apply their discretion when interpreting or using estimated data within tools and calculations.

If you believe any figure — especially those related to recent or estimated years — appears to be incorrect or needs refinement, we welcome your input. Please contact us here and our data team will review the submission promptly.
