Convert New Zealand Grades to US GPA

A+ to E, 0% to 100%, with 10 bands and a pass mark of 50%.

There is no official conversion. Credential evaluators and individual universities publish tables that disagree, and they disagree most at the top of the scale. The classification below is a fact from your transcript; the 4.0 figure beside it is the common convention, not a verdict.

How the New Zealand scale works

The letters look American but the bands are stricter: a New Zealand A starts at 85 where a US A commonly starts at 93 on a 100-point course but is awarded far more often.

In practice the scale runs from 0% to 100% with 10 named bands. The best is A+ (90% to 100%), and the lowest passing grade is C- at 50%. Anything past that is a fail, whatever the number looks like to a US reader.

The reason a single conversion number does not exist is that the two systems measure different things. A US GPA is an average of course grades on a scale where the top is routinely awarded. Most national scales reserve their top band for a small fraction of students, so mapping the numbers proportionally compresses a whole cohort into the bottom half of the 4.0 range. Band mapping — what this page does — avoids that, but every evaluator draws the bands slightly differently.

Frequently asked questions

What is a New Zealand 75% in US GPA?
It falls in the B+ band, which US admissions offices conventionally read as a B+, about 3.3 on a 4.0 scale. Use the calculator above for any other grade. The classification is the part that is certain — the 4.0 number is an approximation, and different evaluators place the boundary in different places.
Is there an official New Zealand to US GPA conversion?
No. WES, Scholaro, ECE and individual university admissions offices all publish different tables, and they disagree most sharply at the top of the scale where it matters most for applications. Anyone presenting a single figure as the official answer is overstating what exists. Submit your transcript with its classification; the receiving institution applies its own table.
How does the New Zealand grading scale work?
A+ to E, running from 0% to 100%. The pass mark is 50%, and the highest classification is A+. The letters look American but the bands are stricter: a New Zealand A starts at 85 where a US A commonly starts at 93 on a 100-point course but is awarded far more often.
Should I convert my grades myself before applying?
Usually not. Most US universities either evaluate the transcript themselves or require a report from a credential evaluation service, and a self-calculated GPA on an application carries no weight either way. What this page is useful for is knowing roughly where you stand before you commit to an application fee.

Local classifications follow each country's national qualifications framework or ministry of education grading regulations; the US letter column follows the convention common to US credential evaluation.

There is no official conversion from a national grade to a US 4.0 GPA. Credential evaluators and individual universities publish tables that disagree, most of all near the top of each scale. Treat the figure here as the common convention and the local classification as the fact; the receiving institution's own table is the one that decides.
