Configuration-average distorted-wave calculations are carried out for electron-impact single ionization of all ionization stages of krypton. Contributions to the cross sections are included from both direct ionization and excitation autoionization. Good agreement with experimental crossed-beams measurements is found for many of the moderately charged ionization stages. Maxwellian-averaged rate coefficients are calculated for each ionization stage and then archived for future use in studies of ionization balance in astrophysical and laboratory plasmas.
