A CAT analysis is a report from a CAT tool that counts the words of a job by match band (repetitions, 100% matches, fuzzy matches and new words) against a translation memory, and is the usual basis for a translation quote.
Trados and memoQ report the same core bands as TraduQ's word count and quote tool, which uses seven:
The CAT tools also report extra categories, such as context matches (101% in memoQ, CM in Trados), X-translated segments in memoQ and locked segments. When you load a Trados or memoQ report into the quote tool, its rows are mapped onto the tool's seven bands.
Each band is billed at a share of the full rate. Multiplying the words in each band by its share and adding the results gives the weighted word count: the number of words you are effectively paid for at the full rate. The percentages are agreed between translator and client; there is no standard grid.
A 10,000-word job, using the quote tool's default grid as one typical example:
The weighted word count is 6,615 words. At $0.10 per word, the translation costs $661.50 instead of $1,000. If the job is tiny, a minimum fee may apply instead.
The quote tool runs the analysis in your browser: drop DOCX, PDF, XLIFF or other files, plus a TMX or Trados SDLTM if you have one, and it counts the words per band, applies your grid and produces a PDF quote. Without a TM it still finds repetitions and fuzzy matches inside the job. Counts can differ by a few percent from Trados or memoQ, because every tool segments and scores in its own way. See the translation rates guide for typical grids.
