BAT and TV Salary Scale
Most doctoral student positions in Germany are advertised as TV-L 13, or sometimes still as BAT IIa or BAT IIa/2. What is that? Here's a quick reference:
General
TV (or TVÖD) stands for Tarifvertrag im Öffentlichen Dienst while BAT stands for Bundesangestelltentarif—both mean tariffs for German civil service employees. The TV tariffs determine the salary based on experience and family situation; the older BAT tariffs depend on age as well as family situation; there is normally no variability based on negotiation or location. These tariffs are periodically adjusted for inflation. In the former East Germany, they are set a bit lower than in the former West, but this difference is decreasing and will eventually disappear.
TV-L 13
TV level 13 is the tariff that doctoral students in engineering, computer science and applied math (high-demand occupations) qualify for. For a single person this means a gross salary of about €2800 per month and about €3100 after one year. Compared to most doctoral stipends in the US, this is a fantastic deal. Working hours are 39.83 per week. That's 10 minutes and 12 seconds less than 40—talk about German precision! Paid vacation is, depending on age, between 26 and 30 days per year, if that's what you're into.
BAT IIa
This tariff was replaced by TV-L 13 in late 2006.
BAT IIa/2
Doctoral students in other fields—pure mathematics, natural sciences, humanities—get half of the BAT IIa salary for the same amount of work. Bummer.
Stipend
Some doctoral positions involve stipends rather than salaries; these are typically part of research training group (Graduiertenkolleg or GRK), i.e., a group of doctoral students working on a single theme. These range between €1100 (standard) and €1500 (augmented, or erhöhtes Stipendium). The advantage of these positions is a structured doctoral program that leads to a doctorate in about 3 years after M.S. Some program like the AICES graduate school offer stipends of €2000, which is more competitive with the TV-L 13 scale, while offering the benefits of a structured doctoral program.
Postdoc
Postdocs are often paid on the same pay scale as the doctoral students, i.e., TV-L 13 or BAT IIa. By virtue of being older and having more experience, that may mean higher salary though. Also, postdoctoral positions with special responsibilities, such as junior research group leaders, may carry higher salary category, e.g., TV-L 14 (formerly BAT Ib) or TV-L 15 (formerly BAT Ia), or even the highest TV-L 15Ü (formerly BAT I). Working hours remain, alas, at the magic 39.83 hours per week.
Calculators
If you know a bit of German, a TV calculator or a BAT calculator can help determine exactly brutto salary, based on your age, experience and family status. Average salaries (including benefits) are also listed in a German document from the DFG (PDF).

OK so home messages are that BAT is gone, now they've got TV-L (go figure the acronyms ;)
Salaries in Germany are pretty decent, highly regulated and transparent which is good I think. For a grad it is usually TV-L 13, unfortunately for postdocs it is usually the same, however they would get more due to age and experience (they will start from higher level or 'stufe').
To tentatively see how much you could get I attach a table with salary ladders.
The one most interesting for us is entgeltgruppe 13. Obviously as a PhD student you start from stufe 1. After two years you find yourself in stufe zwei, after three in level 3 and so on year after year from then on, till you reach level 6. Wages are brutto (yeah I know) so actual money are way smaller. When it comes to german taxes:
* Taxation of an individual's income is progressive. In other words, the higher the income, the higher the rate of tax payable. In 2010 the Germany tax rates for an individual are 14% - 45%.
* Singles pay on income above EUR 250,731 (couples, on income above EUR 501,462) income tax of 45% before 5.5% solidarity tax.
In addition to regular tax, there is a municipal trade tax of 14%-17% that is imposed by the municipality.
I don't know the exact numbers but you can easily subtract 20-30% from brutto salaries.
The table I presented above is for the west germany region. They stil discriminate west from east (they get little less). On top of that areas like Berlin get additional allowance.
Here is a great resource if you can find your way on a german website. You can look up all the salary ladders, and explanations why what and when.
