Kanji 累 accumulate, involvement, trouble 積 volume, product (x*y), acreage Transitive / intransitive 累積する is used both intransitively, as in 損失が累積する (losses accumulate on their own), and transitively, as in 損失を累積する (to accumulate losses deliberately).

累積 (accumulation, building up over time) is easily confused with 累進 because both share the kanji 累, but 累進 specifically means increasing step by step in rank or rate, not just piling up.
