What inflation rate should you use?
This page offers no default rate, deliberately: nobody knows future inflation, and a figure the calculator suggested itself would read as a forecast. For the past, take the actual consumer price index change from Statistics Estonia. For the future, the honest approach is to run several rates and see how far the answer moves between them.
