Although it should be pretty straightforward to estimate your costs for transcription I have found that it has been very difficult to do a direct comparison without validating numbers. To make a complex comparison simple I will only look at billing by the line and not compare that to other methods of billing (page, word etc.). Generally speaking there are three ways to bill by the line:

The  standard which is 65 characters per line which will include spaces and punctuation. Basic (Gross) Method which counts each carriage return as a line. Microsoft Word which uses an embedded line word counter similar to the basic method. The differences in costs of these three measures can be as different as an apple to an orange.

Let me give you an example....
