Grade calculator
Enter your grades, with their weights if they do not all count the same, and get your average right away. You can also work out the grade you need on what is left to reach your goal. Works with percentages and the 4.0 GPA scale.
Enter your grades to calculate the average.

How to use it
- Choose the type of calculation: simple average, weighted average (each grade with its weight), or “What grade do I need?”.
- Pick your grading scale, percentages from 0 to 100 or the 4.0 GPA scale with letters, and enter each grade in its own row. You can also paste a whole list from your spreadsheet.
- If you use weights, enter them as percentages, credit hours, or points. The tool divides by the total of the weights you enter.
- Read your average, median, and mode, and whether you are passing. In “What grade do I need?” you get the lowest grade you need on what is left, plus a table of scenarios.
Frequently asked questions
What is the difference between a simple and a weighted average?
In a simple average every grade counts the same: you add them up and divide by how many there are. In a weighted average each grade has a weight, such as a midterm worth 30% and a final worth 70%, and each grade is multiplied by its weight before adding. With 80 (30%) and 90 (70%), the weighted average is 87 and the simple average would be 85.
Do the weights have to add up to 100?
No. You can use percentages, credit hours, or points, and the tool divides by the total of the weights you enter. If you use percentages, check that no grade is missing and that the weights of all your assignments add up to 100.
How do I find the grade I need on my final?
Multiply the average you want by the total weight (what you already have plus what is left), subtract what your current grades already add up to, and divide by the weight of what is left. If the result is higher than the top grade on the scale, the goal is out of reach, and the tool shows how far you would get with a perfect score.
How do I use the 4.0 GPA scale?
Choose the 4.0 scale and type letter grades (A to F, with plus or minus) or numbers from 0 to 4. To get a GPA, use the weighted average and enter the credit hours of each course as its weight. The tool uses the standard unweighted values (A+ and A are 4.0, A- is 3.7, B+ is 3.3, and so on). Some schools use other values or add a bonus for honors and AP courses.
How do rounding and the passing grade work?
You can show the average with two decimals, one decimal, as a whole number, or to the nearest 0.5. If your school rounds a certain way, pick that option to see the grade as it would appear on your record. Passing is checked against the rounded average. The default passing grade is 60 out of 100 or 2.0 on the 4.0 scale, but you can type your own.
Are my grades saved?
They are not sent to any server. Everything is calculated in your browser. If you turn on “Remember my grades in this browser”, they are kept here so you have them next time, and you can delete them whenever you want.
How the average is calculated
A simple average adds all the grades and divides by how many there are: 85, 78, and 92 add up to 255, and 255 divided by 3 is 85. A weighted average multiplies each grade by its weight, adds the results, and divides by the total of the weights: 80 with a weight of 30 and 90 with a weight of 70 give (80 × 30 + 90 × 70) ÷ 100 = 87.
Median and mode
The median is the grade in the middle once they are sorted, and it helps when one grade is very different from the rest. The mode is the grade that appears most often. If none repeats, there is no mode.
What grade do I need?
If you already have some of your grades, you can solve for the one that is missing. With a 72 and an 81 that count 30% each and a final worth 40%, you need an 85.25 on the final to finish the class with an 80. If the grade you need is higher than the top of the scale, the goal is out of reach and it is better to aim for a lower average.
The 4.0 GPA scale
Many US schools turn letter grades into points: A+ and A are 4.0, A- is 3.7, B+ is 3.3, B is 3.0, B- is 2.7, C+ is 2.3, C is 2.0, C- is 1.7, D+ is 1.3, D is 1.0, D- is 0.7, and F is 0. Pick the 4.0 scale, type your letters, and use the weighted mode with the credit hours of each course to get your GPA.
Tips
- Check the syllabus for how each assignment is weighted and whether rounding applies to each grade or only to the final average.
- If you use percentages, make sure the weights of all assignments add up to 100.
- Try different scenarios to see how much your average changes with each possible grade. To work with other percentages, try the percentage calculator.
