A global and quickly changing world needs more and more detailed economic information on process changes as well as change rate. The article proposes how to calculate interest rates (a rate index of two time moments) taking into account dynamic changes of appropriate sub-periods. To describe a process change intensity between its beginning and end kinetic descriptive functions are used fixing the speedy, average and momentary acceleration. The discussed method (using nominal growth rate terms) lets to fix and compare the processes in real term. The theoretical study is exemplified by change analysis and estimation of average wages and salaries in enterprise sector in Poland from December 2009 to December 2010.
