The basics

What is a GPA calculator?

A GPA calculator works out your grade point average: it multiplies each course grade points (A = 4.0, A- = 3.7, B+ = 3.3 and so on) by the course credits, adds the results and divides by your total graded credits. Math at 3 credits with an A, English at 3 with a B+ and History at 2 with an A- give 29.3 grade points over 8 credits, a GPA of 3.663.

This college GPA calculator does that live as you type, shows every multiplication, adds your previous GPA to give a cumulative GPA, and has a GPA planning mode that tells you the average you need in your remaining credits to hit a target. It is one of several free online calculators on this site that run entirely in your browser.

The default example, worked out
Course Credits Grade Grade points
Math 3 A (4.0) 3 × 4.0 = 12
English 3 B+ (3.3) 3 × 3.3 = 9.9
History 2 A- (3.7) 2 × 3.7 = 7.4
Total 8 29.3
GPA 29.3 ÷ 8 = 3.663
How it works

How to calculate your GPA with this tool

Four steps. The result updates as you type, so there is no Calculate button to press.

01

Add your courses

Enter each course credits and pick its letter grade from A+ to F. The name is optional. Add up to 40 rows, and remove any row with the cross.

02

Match your school scale

Standard 4.0 caps an A+ at 4.0. Choose A+ = 4.3 if your school rewards an A+, or Thirds if your transcript shows 3.67 for an A-.

03

Add your previous GPA

Type the GPA and graded credits from your transcript to get a cumulative GPA that includes this term, weighted by credits.

04

Plan, copy or share

Switch to Plan a target GPA to see the average you need next. Copy the result, download it, or share a link that reopens your exact courses.

Reference

Letter grades and grade points on the 4.0 scale

Plus and minus grades move a letter up or down by 0.3 on the standard scale, or by 0.33 on the thirds scale. Schools differ, so check the table on your transcript.

Grade points per credit for each letter grade
Letter grade Standard 4.0 A+ = 4.3 Thirds
A+ 4.00 4.30 4.00
A 4.00 4.00 4.00
A- 3.70 3.70 3.67
B+ 3.30 3.30 3.33
B 3.00 3.00 3.00
B- 2.70 2.70 2.67
C+ 2.30 2.30 2.33
C 2.00 2.00 2.00
C- 1.70 1.70 1.67
D+ 1.30 1.30 1.33
D 1.00 1.00 1.00
D- 0.70 0.70 0.67
F 0.00 0.00 0.00
P, NP, W Not counted in GPA (no grade points, credits left out)
Cumulative GPA and planning

How cumulative GPA and target GPA are worked out

Cumulative GPA is all your grade points divided by all your graded credits, across every term. To add a new term, multiply your previous GPA by your previous credits to get your previous grade points, add this term grade points, and divide by the combined credits.

(3.2 × 45 + 29.3) ÷ (45 + 8) = 173.3 ÷ 53 = 3.270

GPA planning works the same sum backwards. Multiply the target by the total credits you will have, subtract the grade points you already hold, and divide by the credits still to come. From a 2.8 GPA over 25 credits, a 3.0 after 15 more credits needs:

(3.0 × 40 – 2.8 × 25) ÷ 15 = 50 ÷ 15 = 3.333

If the answer is above 4.0 the target cannot be reached in those credits, and the tool tells you roughly how many credits of straight A grades it would take. Keep the numbers in your online notepad if you want to track them over several terms.

Why you should not average semester GPAs
Credits GPA Grade points
Summer term 3 4.000 12
Fall term 15 3.000 45
Simple average (4.000 + 3.000) ÷ 2 = 3.500 (wrong)
Credit-weighted 57 ÷ 18 = 3.167 (correct)

Use cases

When students use a GPA calculator

Checking a term before grades post

Enter the grades you expect and see your semester GPA and how it moves your cumulative GPA before the registrar publishes it.

Raising a GPA to a target

Switch to planning mode to see the average you need for a scholarship, a major or graduate school requirement, and whether it is realistic.

Deciding on pass or no pass

Compare your GPA with a course graded and with it set to P. Pass grades usually carry no grade points, so the change shows what is at stake.

Applications and transfers

Recalculate your GPA on the 4.0 scale a program asks for. Switch the scale to see how an A+ or a thirds transcript changes the number.

Planning a course load

Try different credit loads in the planning mode. More credits make a target easier to reach, and the best and worst case rows show the range.

Budgeting time and money

Pair your GPA plan with the time calculator to add up study hours, or the expense calculator for the cost of extra credits.

Good to know

Things that change your GPA

Most surprises come from how a school treats credits and grades. If your GPA has more decimals than you need, the significant figures calculator shows how rounding works.

  • Credits weight every grade

    A 4-credit B moves your GPA more than a 1-credit A. That is why the calculator multiplies before it averages.

  • An F counts, a W does not

    An F adds credits with 0 grade points, so it lowers your GPA. A withdrawal usually adds nothing.

  • Pass grades earn credit only

    P and NP are left out of the GPA at most schools, so a pass neither raises nor lowers it.

  • The A+ rule varies

    Many schools cap the scale at 4.0, so an A+ equals an A. Some give 4.3 or 4.33. Pick the scale that matches your transcript.

  • Big GPAs move slowly

    The more credits you have, the less one term changes your cumulative GPA. Planning early leaves more credits to work with.

  • Rounding is a school rule

    The tool shows three decimals, rounded. Some registrars cut off instead of rounding, so the last digit can differ.

Limits

What this GPA calculator does not do

No weighted high school GPA

It calculates an unweighted college GPA. Honors, AP and IB bonus points, which can take a high school GPA above 4.0, are not added.

No repeated course rules

Many colleges replace or average the grade of a repeated course. Enter only the grade your school counts, or ask your registrar.

Not your official GPA

Your transcript is the record that counts. Schools use different scales and rules, as the UW-Madison valid grades list shows with its AB and BC grades.

FAQ

GPA calculator FAQ

Short answers to what students ask most.

How do I calculate my GPA?

Multiply the grade points of each course by its credits, add those numbers, and divide by your total graded credits. For example, 3 credits of A, 3 credits of B+ and 2 credits of A- give 29.3 grade points over 8 credits, a GPA of 3.663.

How is cumulative GPA calculated?

Cumulative GPA is all the grade points you have earned divided by all the graded credits you have taken. To add a new term, multiply your previous GPA by your previous credits, add the new grade points, and divide by the combined credits.

Can I average my semester GPAs to get my cumulative GPA?

Only when every semester has the same number of credits. Otherwise weight each semester by its credits, which is what the previous GPA and previous credits boxes in this calculator do.

What GPA do I need to reach my target GPA?

Multiply the target by the total credits you will have, subtract the grade points you already have, and divide by the credits still to take. From a 2.8 GPA over 25 credits, reaching a 3.0 after 15 more credits needs a 3.333 in those credits.

Is an A+ worth 4.0 or 4.3?

It depends on the school. Many colleges cap the scale at 4.0, so an A+ counts the same as an A, while others give an A+ 4.3 or 4.33. Choose the scale your transcript uses.

Why does my school use 3.67 for an A-?

Some schools add or subtract one third of a point for a plus or minus, so an A- is 3.67 and a B+ is 3.33. The Thirds scale in this calculator uses those values.

Do pass or no pass courses count in my GPA?

Usually not. P, NP and W grades carry no grade points, so this calculator leaves them out of both the grade points and the credits, and lists pass credits separately.

Does an F count in my GPA?

Yes. An F carries 0 grade points but its credits still count, so it lowers your GPA. Many colleges let a repeated course replace the earlier grade, which this calculator does not model.

What is the difference between weighted and unweighted GPA?

An unweighted GPA uses the plain 4.0 scale for every course. A weighted GPA, common in high schools, adds extra points for honors, AP or IB courses, so it can go above 4.0. This calculator gives an unweighted college GPA.

How many decimal places should a GPA have?

Most transcripts show two or three decimal places. This calculator shows three, rounded, and some registrars cut off the extra digits instead of rounding, so the last digit can differ from your transcript.

Is my GPA data saved or uploaded?

Nothing is uploaded. The calculation runs in your browser, your courses are remembered on this device only, and the Share link stores them inside the link itself.
