Rates vary depending upon the type of service offered. Interpreters charge by the hour or sometimes by the day and will often have a minimum charge to account for the possibility of a short or cancelled appointment. Rates are usually higher for the more specialized conference and simultaneous interpreting. Reimbursement of travel, parking, and other expenses is often negotiable and should be confirmed in writing.
Text length and complexity are the determining factors for translation charges. Translators usually charge by the word, line, page, or total text. Services such as extensive formatting, desktop publishing or editing may incur additional charges. Individuals and translation and/or interpretation companies alike are usually willing to provide free estimates. Some translators base their fees on the length of the final translated or "target" text, while others prefer quoting a price based on the "source" text.
