Average Calculator: Simple Averaging for Grades and More

An average is the sum of a set of values divided by the count of those values. It’s one of the most basic calculations in math, and it shows up everywhere. Averaging test scores, averaging assignment grades, averaging stock returns, averaging temperatures. This average calculator computes simple averages where every item counts equally. Enter your values as percentages, points, or letter grades, and it calculates the mean. The average percentage, plus the letter grade and GPA that the average translates to.

three Ways To Calculate THE Average

How to Average Calculator

Each row is one value. You can enter values in three formats

Percent (%)

Enter the percentage directly. If you got 88% on a test, select Percent and enter 88. This is the basic and most used way to calculate.

Points

Enter earned points and possible points. If you got 46 out of 50 on a quiz, select Points and enter 46 / 50. The calculator converts this to 92%.

 Letter (A–F)

Pick a letter grade from the dropdown. The calculator converts it to a percentage based on the grading scheme you selected (US, UK, ECTS, or Australian).

You can mix types. One row can be Percent (88%), another can be Points (46/50), and another can be Letter (B+). The calculator converts everything to percentages, then averages them.
Add as many rows as you need. The calculator shows your average percentage, the corresponding letter grade and GPA, and the range (lowest to highest value). It also gives you a contextual summary based on where your average sits within that range.

What Simple Average Means

A simple average treats all your values equally. Every item you enter counts the same in the final result, regardless of what it represents or how important it might be.

The formula is straightforward:

Average = sum of all values ÷ count of values

If you have five test scores, 85%, 90%, 78%, 92%, 88%, the average is: 85 + 90 + 78 + 92 + 88 ÷ 5 = 433 ÷ 5 = 86.6%.

That is different from a weighted average, in which some values carry more weight in the result. In a weighted average, you would assign weights like “this test counts twice as much as that quiz,” and the formula changes to account for those weights. This calculator does not do that. It is purely equal weighting. Every value counts the same.

Most of the time, when someone says “average” without any qualifiers, they mean simple average. That is what this calculator computes. If you need weighted averaging for items with different levels of importance, there are specific calculators for that. But if you need “add these numbers and divide by the count,” you are in the right place.

Weighted Average Calculator

Use this for academic grading specifically; most scenarios involve weighting. Your syllabus might say “Homework 30%, Midterm 30%, Final 40%.” That’s weighted. You have explicit weights for each item.

Grade Average Calculator

You’re averaging final grades from multiple courses; each course has a credit-hour value (3 credits, 4 credits, etc.).
You want your semester average weighted by credits.

Grade Calculator

You’re tracking a single course across the semester,
You have assignments, quizzes, and exams with different category weights. You want “what if” scenarios.

When to Use Which

Simple Average vs. Weighted Average

The difference between a simple average and a weighted average is whether all your values count equally.

Simple average this calculator: Every value counts the same. If you have three test scores, 80%, 90%, 100%, the average is 80 + 90 + 100 ÷ 3 = 90%. All three tests had equal influence on the result.

Weighted average: Some values count more than others. If the first test had a weight of 1, the second a weight of 2, and the third a weight of 3, the weighted average is (80×1 + 90×2 + 100×3) ÷ (1+2+3) = 80 + 180 + 300 ÷ 6 = 93.33%. The third test raised the average because it carried the highest weight.

Use a simple average when:

  • You are averaging test scores or assignment grades that all count equally.
  • You are calculating a basic mean of any set of numbers.
  • You do not have weights or importance levels assigned to your values.
  • You need to know “what is the average of these numbers.

Use a weighted average when:

  • Different values have different levels of importance.
  • Your syllabus says things like Homework 20%, Tests 50%, Final 30%.
  • Some items should count more in the average than others.

If you need a weighted average, use the weighted average calculator. If you are averaging course grades weighted by credit hours, use the grade average calculator. But if you need a simple, equal-weight average, this calculator is the right tool.

Questions

Frequently Asked Questions

This calculator computes a simple, unweighted average in which all values count equally. The weighted average calculator lets you assign weights to each value so some count more than others. Use this one for basic averaging. Use the weighted average calculator when different values have different importance levels.

The grade average calculator averages grades from multiple courses, weighted by credit hours. This calculator is more general. You can average anything: test scores, assignment grades, or even non-grade numbers. If you are averaging course grades with credits, use the grade average calculator. If you are averaging assignments within a course or need a simple means of numbers, use this one.

Yes. Even though this calculator includes grade-specific features, letter grades, and GPA output, it works for any simple average. If you are averaging numbers that are not grades, enter them as percentages, or ignore the letter/GPA outputs and use the average percentage.

Letter grades are converted based on the grading scheme you selected: US, UK, ECTS, or Australian. For example, in the US scheme with default thresholds, A = 93%, B+ = 87%, B = 83%, etc. You can click “Edit thresholds” to adjust these if your institution uses different cutoffs.

Yes. Each row has a Type dropdown. Set different rows to different types, and the calculator converts everything to percentages before averaging. One row can be Points 85/100, another Percent 88%, and another Letter B+, and they all work together.

“Low” is relative to the values you entered, not to an external standard. If all your values are in the 85-95% range and your average is 87%, the summary might say it is on the lower side because it is closer to the bottom of YOUR range. The summary compares your average to your own data, not to a grading scale.

There is no hard limit. Click “Add row” to create as many rows as you need. Most people have 3-10 values, but the calculator can handle more if needed.
