Your US GPA is not your German grade
The GPA-to-German converters online give one number; your uni-assist VPD often gives another. The gap is not an error. It comes from which formula is used, which values feed it, and which GPA uni-assist actually asks for.
On this page
German conversion is set by a KMK resolution, not a GPA table. Your grade is calculated with the modified Bavarian formula, German grade = 1 + 3 × (Nmax − Nd) / (Nmax − Nmin), where Nmax and Nmin are the ZAB reference values held in anabin and Nd is your average. Two things then separate the VPD from a number you calculate yourself. First, uni-assist's US page asks high school applicants for their unweighted CGPA from grades 9 to 12, so a weighted GPA gives a different average. Second, the result is set to one decimal and not rounded, so 2.875 becomes 2.8, not 2.9. uni-assist publishes no GPA table and assesses your certificates using the ZAB's specifications.
Weighted GPA is the wrong input. uni-assist asks high school applicants for their unweighted CGPA. A weighted GPA (the 4.5 or 5.0 kind) feeds the wrong average into the formula.
The method is public. The KMK resolution states the formula and every variable, so you can calculate an estimate before the VPD arrives.
No grade proof means the lowest passing grade. The KMK states that qualifications documented only indirectly, without proof of grades, enter at the lowest passing grade.

Estimate your German grade
Enter your numbers. The result uses the KMK modified Bavarian formula, cut to one decimal and not rounded, exactly as uni-assist calculates it.
your GPA or diploma average
e.g. 4.0 or 100
from Diploma Supplement 4.2 or anabin
Enter all three numbers to see your estimate.
An estimate. Your real Nmin comes from your Diploma Supplement and the ZAB values in anabin; the final grade is uni-assist's.
Which situation is yours?
Find the row closest to you, confirm your own values, and submit the right document.
| Your situation | What the rule says | Your next step |
|---|---|---|
| You applied with a high school diploma | uni-assist asks for your unweighted CGPA from grades 9 to 12, with seal and signature | Unweighted CGPA [2] |
| You studied at a US university | uni-assist needs official transcripts issued by your university with seal and signature | Official transcript [2] |
| You used an online GPA converter | It assumes a generic 4.0 scale; the formula uses the ZAB values in anabin, so the two can differ | Treat as estimate [1][4] |
| You cannot prove your grades | Qualifications without grade proof count at the lowest passing grade | Worst case [1] |
uni-assist publishes no GPA table and assesses your certificates using the ZAB's specifications. The converted grade can be rechecked against your documents, and the university makes the final decision.
Bottom line
Your German grade comes from the KMK's modified Bavarian formula with the ZAB reference values in anabin, set to one decimal and not rounded. A GPA converter is a sanity check, and it should use your unweighted CGPA. [1][2]
The KMK resolution sets the method, while uni-assist's US page asks for the unweighted CGPA and publishes no conversion table of its own.
Take your unweighted CGPA, look up your qualification's values in anabin, and run the formula. Submit your official diploma or transcript with seal and signature.
High school: the unweighted CGPA, not the weighted one
uni-assist's US page is specific about the high school route. It asks for an overview of subjects and grades from grade 9 to 12 stating your unweighted CGPA, issued by your high school with seal and signature.
That one word, unweighted, is where many US files diverge from the applicant's own estimate. A weighted GPA that rewards AP and honors courses on a 5.0 scale is a different average, so it feeds a different number into the formula. Take the unweighted CGPA, not the one on your class rank report. [2]
University: the official transcript
If you have completed US university study, the document is different. uni-assist accepts only official transcripts issued by your university with seal and signature, covering all studies undertaken.
Either route, uni-assist assesses your certificates using the ZAB's specifications, so the grade on the VPD comes from the formula below, not from the GPA printed on your document. [2]
The formula, and why the converter differs
There is no binding US-GPA-to-German table. The rule is the KMK resolution, which converts foreign grades with the modified Bavarian formula, X = 1 + 3 × (Nmax − Nd) / (Nmax − Nmin), where Nd is your average and Nmax and Nmin are the ZAB reference values in anabin.
Most converters assume 4.0 and 0.0. Do not rely on that generic assumption: base it on the official grading system for your diploma and the ZAB evaluation, which is why the converter and the VPD often disagree.
As an illustration on the 4.0 scale with Nmax = 4.0 and a lower endpoint of 1.0, a 3.5 gives 1 + 3 × (4.0 − 3.5) / (4.0 − 1.0) = 1.5, a 3.0 gives 2.0, a 2.5 gives 2.5. These are a demonstration of the formula, not a claim that anabin holds 1.0 for every US qualification. And the KMK sets the result to one decimal without rounding, so a computed 2.875 is recorded as 2.8. [1][4]
Which document proves your grading scale
uni-assist wants the grading system in an official form, and a link is accepted: a link to your university's own grading-system page, or an official PDF. Only links to anabin or Wikipedia are not enough.
Use anabin to understand your number, but submit your school's own official document, with seal and signature, with the application. [2][3]
You converted your grade. Which application route fits you?
We are an independent service, not affiliated with uni-assist e.V. Knowing what your GPA becomes in the German system is half of it; the other half is which route your diploma or degree opens. Five questions and you have it.
- Five questions, about two minutes
- No account and no payment
- Your route and the documents it needs, by email
- An advisor reviews your case if it is not clear-cut
Our fee includes uni-assist's handling fee, and your documents are checked before you pay anything.
The formula above is the KMK's. The route here is our preliminary reading, not an official evaluation.

Frequently asked questions
Why is my uni-assist VPD grade different from the GPA converter I used?
The converter assumes a generic 4.0 scale; the formula uses the ZAB values in anabin, and uni-assist asks for your unweighted CGPA. Different inputs give a different number.
Weighted or unweighted GPA?
Unweighted. uni-assist's US page asks high school applicants for the unweighted CGPA from grades 9 to 12, with seal and signature.
Why is 2.875 recorded as 2.8?
The KMK resolution states the grade is set to one decimal place and not rounded. It is cut, not rounded up.
Is the converted grade final?
No. It is rechecked against your submitted documents, and the university makes the final decision on both the grade and admission.
