How to estimate your average
- Choose a preset and compare its grade values with your school’s scale. Changing presets clears entered grades and prior totals.
- Replace the sample courses with your grades and credits. Add or remove rows as needed; use positive credits for courses you want to include.
- Read the weighted estimate. The calculator divides the sum of grade value × credits by total credits and displays two decimal places.
- For a cumulative estimate, enter your prior average and credits using the same scale. Check repeats, exclusions and rounding with your institution.
Frequently Asked Questions
Is this my official GPA?
No. This browser calculator uses preset example values. It does not apply your institution’s rules for repeated courses, excluded grades or transcript rounding.
Can I convert between grading systems?
No. Changing the preset clears grades and previous totals. Enter values for the new scale; this tool does not certify equivalence between systems.
Do I need an account?
No. Calculation runs in this browser without an account or an AI request. The calculator has no transcript import or account-saving action.
