IU GPA Calculator

How the IU GPA Calculator works

The IU GPA Calculator computes a credit-weighted grade point average: courses worth more credit hours count proportionally more toward your GPA. Enter each course's letter grade and credit hours, and the tool totals your quality points and divides by your total graded credits.

Indiana University uses a complete plus/minus scale. An A+ and A are both worth 4.0, and the scale runs all the way down to D- (the lowest passing grade) before F.

It works for a single semester or for your full cumulative record — just add every course you want included. Pass/Fail, Withdraw and other non-graded marks should be left out, since they do not carry grade points.

Formula & grading scale

Every grade maps to a point value. Multiply each grade's value by the course's credit hours to get its quality points, sum them, and divide by total credits:

The Indiana University uses this grade scale:

Only graded marks from A+ through F count toward the GPA. Pass/Satisfactory (P/S) grades and Withdraw/No-Credit (W/NC) marks are excluded. IU does not automatically drop repeated courses.

Step-by-step example

Suppose you took three courses in a term:

1. Biology — grade A (4.0) × 4 credits = 16.0 quality points.
2. Calculus — grade B+ (3.3) × 3 credits = 9.9 quality points.
3. English — grade B (3.0) × 3 credits = 9.0 quality points.

Total quality points = 16.0 + 9.9 + 9.0 = 34.9. Total credits = 4 + 3 + 3 = 10. Your GPA = 34.9 ÷ 10 = 3.49 on the 4.0 scale. (Exact point values depend on the scale shown above.)

Why use the IU GPA Calculator?

You should not need a spreadsheet to know where your average stands. The IU GPA Calculator lets Indiana University students check a single term or a full cumulative record in seconds, with the math running privately in your browser. Adjust a grade to test a "what-if" scenario before registration or finals as often as you like.

What is a good GPA at Indiana University?

At Indiana University, a 2.0 is the usual minimum for good standing, 3.0 is respectable, and 3.5+ is competitive for honors, scholarships and graduate study. IU's full plus/minus scale means grades like B+ versus B- can make a real difference over time.

How to raise your GPA at Indiana University

Focus on your highest-credit courses first, because they shift your average the most — a better grade in a four-credit class outweighs the same change in a one-credit course. Watch the running quality points update as you enter grades, then model a realistic target. At IU both A+ and A are worth 4.0, and the scale extends down to D- as the lowest passing grade. For the math behind it all, read our guide on how GPA is calculated, express your result differently with the GPA to Percentage Calculator, or compare schools using the Oakland and Colorado State GPA calculators.

GPA tips for Indiana University students

A few principles apply no matter your major. Your GPA is cumulative, so early grades set a baseline that later terms can only move gradually — a strong start compounds in your favour, while a slow one takes time to recover from. Retaking a weak course can help if Indiana University applies a repeat or grade-forgiveness policy, but confirm the details with the registrar first, since this calculator counts every grade you enter by default. And rather than overloading on extra classes, protect the grades in your highest-credit courses, because that is where your average is won or lost. Run the numbers at the start of each term to set a realistic goal, then check back as grades are posted so there are no surprises at the end.
