TDD

Are there any guidelines when quoting estimates for projects/tasks involving TDD?

For example, when compared to normal development of a task taking 1 day to complete, how much more should a TDD driven task take? 50% more time or 70% more time? Are there any statistics available, assuming the developer is well versed with the language and the test framework?
