# How to calculate grades based on percentage

To calculate overall grade from assignment grades by percentage, click on percentage tab. Assessments are optional, they will not be taken into accounts during calulation. The result is weighted average grade.

gn: grade of the nth assessment

wn: weight of the nth assessment

Grade = ( g1×w1+ g2×w2+ g3×w3+...+ gn×wn)÷ (w1+w2+w3+...+wn)

## Example of percentage grade calculator

Think about a student got scores in percentage like the following table:

Quiz 90% 20%
Midterm 91% 30%
Homework 92% 20%
Final 93% 30%

The class weighted grade would be:

Grade = (90x20+91x30+92x20+93x30) ÷ (20+30+20+30) = 91.6

# How to calculate grades based on letters

Click on letters tab, if your grades are letter based. The letter grade calculator maps letters to numbers according to the grading scale table below. Schools or universities may use different grading scale, so that the result would be slightly different. Please report to us if it's not accurate enough for your school/university.

gn: grade of the nth assessment

wn: weight of the nth assessment

Grade = ( g1×w1+ g2×w2+ g3×w3+...+ gn×wn)÷ (w1+w2+w3+...+wn)

## Example of letter grade calculator

Think about a student got grades in letters like the following table:

Quiz A 20%
Midterm A 30%
Homework A- 20%
Final B+ 30%

Grade = (4*20+4*30+3.67*20+3.33*30) ÷ (20+30+20+30) = 3.73(A-)

# How to calculate grades based on points

gn: grade of the nth assessment

mn: max points of the nth assessment

## Example of point grade calculator

Think about a student got scores in percentage like the following table:

Quiz 55 60
Midterm 90 100
Homework 91 100
Final 92 100

The class weighted grade would be:

Grade = (55+90+91+92) ÷ (60+100+100+100) = 91.11(A-)
