# How to Calculate Your GPA–Letter Grades and Percentages

One of my most popular posts is about how to calculate your “real” GPA. Some readers have asked how to translate grades expressed as a percent into letter grades, and then into a GPA based on a 4.0 scale.

Below is a chart that can serve as a starting point. Recognize, however, that all schools and colleges will have their own grading policies. This is one way to translate one kind of grade into another. It’s meant as a helpful tool, but you should always investigate how individual colleges and schools handle this translation before making any assumptions about how they will consider your own performance.

If you’re worried about your GPA, it’s likely that you are a bit nervous about how your GPA will affect your admission to college. There are three things to keep in mind.

First, it’s not just about your GPA overall. You need to pay close attention to your *core* GPA.

Second, you need to think first about which colleges fit you best. It may turn out that you are worrying too much for the wrong reasons.

Third, if you are having trouble fitting all these pieces together–your GPA, your test scores, your interests, your aptitudes–you may want to consider asking for some professional advice from an expert who can help you navigate the college admissions process.

Hi Helly,

I don’t think there is any standard way to convert the grades from IB to a US system. You may want to see if their is a local high school with an IB program in your area that can offer any insights.

Katherine

thanks so much 4 this!!!

Hello Jeannie,

We would need to know the full breakdown of the scale you are suing in order to help you calculate your grades.

D+ should be 67-69%, no? Thee is an error in the chart.

a “3.6” is an A- NOT a B+

Hi, Annabell. As this post points out, not every school treats grades the same. However, a 3.7 is usually considered the the dividing line between an A- and a B+ If your school does it differently, that’s cool. But how does the college to which you may be applying see it? That is perhaps, the more important question. Some high schools are actually eliminating the “+” and “-” from the transcripts. This is nice when the grade is an A-. But not so great when it is a B+. As in everything in life, win some, lose some!

Thanks for writing in.

Im in College and my Gpa is 3.50 is that good enough to be on th e Dean’s List?

That depends on the policies of your college, which should be available on the college’s website.

Best regards,

Mark

What is a 3.611?

Well, it’s a pretty good GPA, that’s what! Depending on the grading system in use, it’s just shy of an A-. A 3.7 would push it over the edge. Of course, ad 3.8 would be even better. But then again–you already knew that, Max. Thanks for writing in!

Hello, Mina.

I have to apologize. But your question just isn’t very clear. I cannot follow your meaning. Perhaps you can try again?

Thanks.

Hello.

I saw in a separate thread that my GPA may be artificially inflated due to electives and other, non-academic subjects.

If I take my unweighted total GPA, I am on the cusp of a 4.0 (92%) however, if I only include my core classes, I have slightly below a 3.5 GPA. Is this a critical factor? Will colleges refuse to accept me if this is my core, unweighted GPA?

If it is at all relevant, I am taking two honors courses, and for my sophomore year I will be taking a significantly more strenuous curricula (5 AP, 1 Honors) you may remember my post. If not, I would be glad to offer a link.

If I take my unweighted total GPA, I am on the cusp of a 4.0 (92%) however, if I only include my core classes, I have slightly below a 4.0 GPA. (89%) Is this a critical factor? Will colleges refuse to accept me if this is my core, unweighted GPA?

By the way, this is calculated according to the college board GPA scale.

I’m in an Indian CBSE board school. Here, we’re not given percentages. We’re just given grades with upper and lower limits. For example,

A1= 91-100

A2= 81-90

B1= 71-80

and so on, all the way up to E.

I’m trying to figure out the equivalent American GPA just for personal interest. How would I go about trying to calculate it? Would I take the upper limit or the lower limit percentage for my grade?

Taking a hypothetical situation, if I got all A2’s, then would I have an unweighted GPA of 3.3 or 3.7?

Thanks. I really appreciate you taking the time to look at this.

Hi i am in 12th grade cbse and how do i convert my percentage to american gpa

Hi, I am a High School teacher.

The 4 point grade scale was designed according to the standard distribution curve, most commonly known as the “Student’s t-distribution” curve, with grades grouped corresponding to standard deviations.

Montgomery’s conversion table – like many others I have seen – is based on a linear correspondence model. The 4 point system is NOT linear so the correspondence is not correct; I find this type of conversion model to be rather simplistic.

This discussion points out that grading in the USA should be standardized at the national level because most colleges admission policies use linear conversion model like this one that tend to discriminate against some students because their high school grading system is not converted correctly.

Thank you.
