How translation quotes are calculated

A rate needs a defined unit and scope

A unit rate becomes meaningful only when the unit is defined. A source-word quote, a target-character quote and a standard-page quote cannot be compared simply by looking at their headline figures. Each proposal should identify the files, language direction, counting method and included stages. It should also state how source changes and additional requests will be handled.

The starting point is a complete source package, rather than an estimated number of visible pages. Editable files, reference PDFs and a version list help establish what is being measured. The translation preparation guide explains the information needed for a usable brief. A preliminary estimate should identify any assumptions that could change after inspection.

A purchase comparison should place equivalent deliverables side by side. Translation of running text, bilingual revision, extraction of image labels and checking a final PDF are different activities. A proposal that bundles them can still be transparent if it identifies the included scope. A short quote that lists only a word rate can leave major work undefined.

Per source word and per character

A source-word method counts the approved source text before translation. This can make the volume predictable at order stage. The agreement should still state how the count treats numbers, hyphenated expressions, embedded text, hidden sheets and repeated segments. Different extraction and segmentation settings can produce different totals from files that appear identical on screen.

Character-based charging needs equally clear rules. The quote should specify whether spaces are included and whether the count uses source or target text. A target-based count may remain provisional until delivery because translation changes length. A source-based count fixes a different measurement point. Neither method should be silently substituted for the other during invoicing.

For scanned material, a reliable count may require text extraction first. Headers, handwritten additions and diagram labels may need manual inspection. The quote should distinguish an estimate based on the visible document from a count of verified extracted text. Low-quality extraction can hide omissions as well as distort the commercial volume.

The standard page: 1,800 characters

A standard page is a volume unit, not a physical A4 sheet and not an ISO 17100 pricing requirement. A common definition is 1,800 characters including spaces, used in several Central and Eastern European markets; other markets price by source word or line. Definitions differ between buyers and providers, so the quote should state the one it uses. Convention checked 31 October 2026.

Under that definition, 18,000 counted characters represent ten standard pages before any agreed rounding or minimum. This is a volume example, not a price. Ten printed pages can contain substantially more or less text. A document with large diagrams and one with dense tables therefore cannot be scoped reliably from the physical page total alone.

The proposal should specify whether standard pages are calculated from the source or the finished translation. It should also explain partial-page rounding and whether rounding occurs per file or across the whole order. These details can materially affect a batch of short documents, even where the same stated page definition is used throughout.

CAT analysis and repetitions

A CAT analysis groups source content by repetitions and similarity to available translation-memory material. Typical categories include new content, fuzzy matches, exact matches and context matches. The report should identify the memory set, thresholds, files and settings used. Otherwise, two analyses of the same apparent source package can describe different opportunities for reuse.

A repeated segment may need less new translation but still require checking in context. A 100% source match can retrieve an obsolete target sentence or the wrong approved terminology. The translation glossary explains the match categories. Their percentages describe the tool’s matching rules, not a percentage guarantee of accuracy.

Commercial weights are negotiated rules applied to those categories. They should be shown separately from the raw counts, so the buyer can see how a weighted volume was calculated. No universal discount follows automatically from a fuzzy or exact match. The quality of the memory, subject matter and included checking affect the work that remains.

Repetition treatment also needs an agreed file boundary. Repeated text within one file, across a batch and against an existing memory can fall into different categories. If delivery is split into stages, the order of analysis may matter. A comparison should therefore use the same source baseline and a clearly described analysis method.

Minimum fees and short assignments

A short translation can still require file preparation, scheduling, terminology decisions, revision and delivery administration. A provider may therefore use a minimum fee or minimum chargeable volume. The quote should state the rule and whether it applies per order, language, file or delivery batch. A minimum is a commercial condition, rather than a measure of text length.

Buyers planning many small updates can ask how batches will be treated. Grouping work may reduce repeated preparation, but only if versions and delivery requirements remain manageable. A batch should not obscure which files have been approved or which languages need an update. The commercial arrangement and the document-control arrangement need to support the same workflow.

Complexity, formats and urgency

Subject complexity affects research and checking effort. A familiar product description and a technically dense procedure can have the same word count but require different domain knowledge. The source’s clarity also matters. Undefined abbreviations, inconsistent terminology and contradictory references create questions that cannot be resolved simply by processing words faster.

File work can include extraction, preparation, protection of tags and reintegration. For technical translation, diagrams and cross-references may need particular attention. The buyer should ask whether image text and final-output checks are included, without assuming that a provider supplies a particular layout service merely because the source contains designed pages.

An urgent request may require changed scheduling, additional coordination or a different delivery arrangement. The provider needs to inspect the source and available resources before confirming feasibility. A requested date is not a promise. Any proposal should state what is included and which dependencies, such as timely answers to terminology queries, affect the agreed plan.

Revision and optional checking stages

ISO 17100 includes revision by a person other than the translator. A quote for that workflow should not be compared as equivalent to translation alone. Optional specialist review and proofreading have different purposes, explained in the ISO 17100 buyer guide. The proposal should identify the checking object and the stages included in the price.

Client review creates a further scope question. Product validation, preferred wording and correction of a source error are not necessarily the same kind of amendment. The buyer and provider should agree how feedback is consolidated and how later source changes are treated. A clear agreement helps prevent a terminology preference from becoming an undefined reopening of previously approved material.

Compare totals against the same deliverable

A comparison record should include raw volume, chargeable volume, rate basis, any minimum, preparation work and included checking. Currency, tax treatment and quote validity should be stated in the proposal rather than inferred. These are comparison fields, not claims about Babylon’s commercial terms. The buyer should also record any exclusions that would require a separate order.

The most useful final question is whether the proposal covers the actual publication package. A cheaper text-only delivery can leave reintegration and checking with the buyer. A broader project fee may include coordination that another quote excludes. Comparing both against the same approved files and quality stages makes the purchasing decision more reliable than comparing unit prices alone.
