Grade to GPA Calculator
Put in a letter grade, a percentage or a number of grade points, and this grade to GPA calculator fills in the other two, on whichever grading scale your school actually uses. If you want to average several courses together instead, the grade calculator gpa tool handles credits and a full term.
Type into any one of the three boxes. The other two fill themselves in, on whichever scale you picked above. Schools do not agree on these, so pick the one your handbook uses.

How to use this grade to GPA calculator
The three boxes are the same value in three different currencies. Type into whichever one you already have and the other two fill themselves in.
- Letter grade. Pick it from the list. The list changes with the scale, because not every school awards a D− or an A+.
- Percentage. Type the number your gradebook shows. It lands in a band, and the band decides the letter.
- GPA points. Works backwards. Enter 3.7 and you get the letter and the percentage range that produce it.
The control above the boxes matters more than it looks. Schools do not use one scale. Pick the one your handbook describes, and everything below it, including the chart, changes to match.
Course type is separate. Leave it on Standard unless the course is honors or AP, in which case the result also shows what the grade is worth once your district’s weighting is applied.
The conversion chart
This is the plus and minus version of the 4.0 scale, the one the calculator starts on. It will redraw its own chart if you pick a different one.
Not every institution stops at 4.0. We found seven colleges where a GPA can exceed 4.0, because their A+ is worth 4.3 or more, and two states then flatten it back down for scholarship purposes.
| Letter | Percentage | Grade points |
|---|---|---|
| A+ | 97 to 100 | 4.0 |
| A | 93 to 96.9 | 4.0 |
| A− | 90 to 92.9 | 3.7 |
| B+ | 87 to 89.9 | 3.3 |
| B | 83 to 86.9 | 3.0 |
| B− | 80 to 82.9 | 2.7 |
| C+ | 77 to 79.9 | 2.3 |
| C | 73 to 76.9 | 2.0 |
| C− | 70 to 72.9 | 1.7 |
| D+ | 67 to 69.9 | 1.3 |
| D | 63 to 66.9 | 1.0 |
| D− | 60 to 62.9 | 0.7 |
| F | anything below 60 | 0 |
Two things about this table are worth saying out loud. Each plus adds 0.3 and each minus takes 0.3 away, which is why the numbers look untidy. And an A+ is worth the same 4.0 as a plain A here, so on this scale the plus is recognition rather than extra credit.
Why schools disagree, and which scale is yours
The conversion pages that rank for this keyword print a single table and leave it at that. Put two real published scales side by side and they disagree in ways that change your number.
UNC Chapel Hill publishes the scale in the table above: tenths, A+ absent from the point list, F at zero. Columbia’s School of Professional Studies publishes percentage, letter and points together, and differs on four counts:
| Point of difference | Plus / minus scale | Columbia SPS |
|---|---|---|
| An A+ is worth | 4.0 | 4.33 |
| An A+ starts at | 97 | 98 |
| An A− is worth | 3.7 | 3.67 |
| D+ and D− | both exist | neither exists; D covers 60 to 69.9 |
A third position exists at the University of Missouri and Indiana University’s Kelley School, where an A+ is listed at 4.00, the same as an A.
A fourth position, and the one that shows the limit of tables like these, is the University of Florida, which publishes point values and no percentages at all:
| Letter | UF points | Letter | UF points |
|---|---|---|---|
| A | 4.00 | C+ | 2.33 |
| A− | 3.67 | C | 2.00 |
| B+ | 3.33 | C− | 1.67 |
| B | 3.00 | D+ | 1.33 |
| B− | 2.67 | D | 1.00 |
| D− | 0.67 |
Two things in that list appear in none of the tables above it: there is no A+ to award, and the failing grade is lettered E rather than F. The third difference is what is absent. UF publishes no percentage band for any letter, so a chart that shows a UF A starting at 93 is quoting a figure the university has not published.
None of these is wrong. They are different institutions describing their own rules, which is exactly why a single universal conversion table cannot exist. The practical consequence is small until it is not: a transcript full of A grades converts identically everywhere, while one containing an A+ or a D+ can land on a different GPA depending on whose table you used.
Find the grading scale in your syllabus, your student handbook or your registrar’s website, then set the control on the calculator to match. It takes a minute and it is the difference between a number you can quote and a number you guessed.
Going the other way: GPA to a letter grade
Converting a letter into points is exact. Going backwards is only exact some of the time, and a tool that always hands back a single letter is hiding that from you.
If the number came from a single course, the reverse works cleanly. A 2.3 was a C+, because that is the only grade worth 2.3. Type it in and you get the letter and the percentage band back.
A cumulative grade point average is different, because it is an average. A 3.5 is not a grade anybody was ever awarded. It sits between a B+ at 3.3 and an A− at 3.7, and the honest answer is that it lies between them rather than being one of them. The calculator says so instead of rounding to whichever letter happens to be nearer, which is why entering 3.5 returns a range and not a letter.
That matters when an application form asks for a letter equivalent. Reporting a 3.5 as an A− overstates it and reporting it as a B+ understates it. If the form insists on a letter, the safe move is to give the GPA itself and let the reader convert on their own scale.
Honors and AP on a 5.0 scale
Some districts add points for harder courses, so the same letter can be worth more than the chart above suggests. St. Johns County School District in Florida publishes the amounts: honors courses carry an extra 0.5; AP, dual enrollment, AICE and IB courses carry an extra 1.0. An A in an AP course is therefore worth 5.0 rather than 4.0.
Set the course type on the calculator and your weighted GPA value appears beside the unweighted one. The unweighted figure never changes, which is the point of having both.
One detail trips people up. An F earns no bonus at all. It is zero in the standard column, zero in the honors column and zero in the AP column, so failing a hard course does not soften the blow. This calculator follows that rule.
Weighting is set by your high school district rather than nationally. Some run 1.0 and 2.0 instead of 0.5 and 1.0, and some do not weight at all, so check your own handbook before relying on the weighted figure.
The percentage shortcut that gets it wrong
Search for a percentage to GPA conversion and you will meet this formula quickly:
It is tidy, it is easy to remember, and it does not describe how any US school calculates a GPA. On that rule 85 percent becomes a 3.4. On Columbia’s published table 85 percent is a B, worth 3.00. The shortcut is not rounding differently; it is inventing a number that no registrar would recognize.
The reason it fails is that percentages do not map to grade points directly. They map to a letter, and the letter maps to a grade point. That middle step is where your school’s cutoffs live, and skipping it throws them away. It also produces answers that make no sense at the bottom of the range, where 50 percent becomes a 2.0 rather than the F it plainly is.
The formula does have a home. It circulates on study abroad sites putting foreign percentage marks onto a rough 4.0 footing where there are no letter grades to work from. If you are converting marks earned outside the US, that is a conversation to have with the admissions office or an international credential evaluation service rather than with a calculator, because the mapping depends on the country’s own grading system and not on any US scale.
From converted grades to an actual GPA
Converting one grade is the first step. A grade point average is the second, and it is not the average of the grade points you just looked up. Credits weight it, so a 4.0 in a one credit seminar moves your GPA far less than a 2.0 in a four credit lecture.
The arithmetic is short:
Say you convert three courses on the plus and minus scale: an A− worth 3.7 in a 4 credit course, a B worth 3.0 in a 3 credit course, and a C+ worth 2.3 in a 2 credit course. That gives 14.8, 9.0 and 4.6, which is 28.4 quality points across 9 credits, and 28.4 divided by 9 is a 3.16 GPA. Averaging the three grade points on their own would have given 3.0, which is a different number and the wrong one.
This page stops at the conversion on purpose, because a full college transcript with credits, terms and honors weighting is a different job. The GPA calculator linked at the top of this page does that part.
Where to go next
This page converts one grade. Two neighbors pick up where it stops.
If you want to know where a percentage lands as a letter and nothing about GPA points, our letter grade tool does that in both directions and lets you edit the cutoffs to match your own syllabus.
And if you are stacking those grade points into a college transcript rather than converting one at a time, projecting a cumulative college GPA is the next step, retakes and pass/fail included.
Where the two scales themselves differ, converting a grade between grading scales is its own job, including what disappears when a plus or minus is dropped.
If you have several courses and want them averaged into one figure with credit hours taken into account, that is a different calculation and it lives on the GPA calculator linked at the top of this page. High school transcripts have their own conventions, and working out a high school GPA covers the honors and AP weighting those use.
Converting one grade at a time is the step before the average. Once whole terms are finished and you want them rolled together, combining whole terms into one cumulative figure works from the totals your transcript already prints rather than from individual grades.
If the report card in question is a middle school one, a middle school GPA from finished subject grades is the version with credits optional rather than assumed.
Frequently asked questions
What GPA is 84 percent?
On the plus and minus scale 84 percent falls in the 83 to 86.9 band, which is a B, worth 3.0 grade points. On a whole letter scale, where B covers 80 to 89.9, it is still a B and still 3.0. The answer only moves if your school sets its bands differently, which is worth checking in the syllabus, and it is why the calculator above lets you switch scales rather than assuming one.
Is a C+ a 2.0 GPA?
No, a C+ is 2.3. A plain C is the one worth 2.0. The plus adds 0.3 and the minus takes 0.3 away, so the C band runs C− at 1.7, C at 2.0 and C+ at 2.3. On a whole letter scale there is no C+ at all and everything from 70 to 79.9 is simply a C, worth 2.0, which is one more reason the scale you pick changes the answer.
What is 70 percent in GPA?
On the plus and minus scale 70 percent is the very bottom of the C− band, worth 1.7 grade points. One percent lower and it becomes a D+ at 1.3. Sitting exactly on a boundary like that is worth double-checking against your own school’s table, because a band that starts at 70 in one handbook starts at 69.5 in another, and the difference is a whole grade step.
What is a 4.0 GPA in letter grades?
An A. On all three scales on this page a 4.0 is the value of an A, and on the plus and minus scale an A+ is worth the same 4.0. If your school runs the 4.33 scale, then a 4.0 is still an A, but it is no longer the ceiling, because an A+ sits above it at 4.33. A cumulative 4.0 means every graded course came out at A or better.
Is a 2.7 GPA a letter grade?
It can be either, and which one depends on where the number came from. As a single course grade, 2.7 is exactly a B−. As a cumulative GPA, it is an average of everything you have taken, and averages rarely land on a letter. A 2.7 cumulative might be a transcript full of B− grades, or a mix of B and C+ work that happens to average there. If a form asks for a letter equivalent, giving the GPA itself is more accurate than picking a letter for it.
How do I convert my percentage to a GPA?
In two steps, not one. Find which band your percentage falls into on your school’s scale, which gives you a letter, and then read the grade points for that letter. The calculator above does both at once. What you should not do is divide your percentage by 100 and multiply by 4, a shortcut that produces numbers no US registrar would recognize.
Does an A+ count as 4.0 or 4.33?
Both exist, which is why the calculator lets you choose. Missouri and Indiana’s Kelley School both list an A+ at 4.00, identical to an A, so the plus is recognition rather than extra credit. Columbia’s School of Professional Studies lists it at 4.33, above the usual ceiling. Check your registrar’s grading page, because using the wrong one inflates or deflates every A+ on your transcript.
My school has no D+ or D−. Does that change my GPA?
Yes, for any grade in that range. Columbia’s scale has no D+ and no D−, so everything from 60 to 69.9 is a flat D worth 1.0. On a plus and minus scale the same 68 percent would be a D+ worth 1.3. Over a single course the gap is small; across several it is the kind of difference that moves a cumulative GPA by a few hundredths. Pick the whole letters or 4.33 option on the calculator if your school works this way.
Every result here is an estimate. Your school sets the grading scale, the percentage cutoffs, any honors or AP weighting and the way it rounds, and the registrar’s own record is the only one that counts. Check it before anything important depends on a number from this page.
