Score Breakdown
How The Grade Average Calculator Works
A simple grade average gives each included score equal weight.
Add scores
Each score is treated as a percentage and added to the included score total.
Drop if needed
When drop-lowest is enabled, the lowest percentage is excluded before the average is calculated.
Divide by count
The included score total is divided by the number of included scores and mapped to a common letter-grade scale.
Grade Average Calculator FAQ
Common questions about simple averages, dropped scores, and weights.
How is a grade average calculated?
Add the included percentage scores together, then divide by the number of included scores.
When should I use drop lowest?
Use drop lowest only when your class policy says the lowest quiz, test, or assignment score is excluded from the average.
Is this the same as a weighted grade?
No. A grade average treats each entered score equally. Use the Weighted Grade Calculator when categories or assignments have different weights.
