How the assignment weight calculator works

Calculate how a scored assignment changes a current course grade.

Updated grade = current grade × (1 − weight) + assignment score × weight.

An 80% course grade followed by a 90% assignment worth 20% becomes 82%.

Assumptions and limitations

The current grade represents all work outside the new assignment, normalized to the remaining course weight.

Inputs and results stay in your browser. Blank, invalid, or mathematically undefined inputs show a clean placeholder instead of a broken number.

Frequently asked questions

Does the assignment weight calculator send my data anywhere?

No. It runs client-side in your browser and makes no network requests.

Why is the result blank or shown as a dash?

One or more inputs are blank, outside the accepted range, or would make the calculation undefined. Check the labels and enter finite values.

Can I use decimal values?

Yes, where decimals are meaningful. Counts that represent whole items may require integers.
