Overall GPA Calculator
Use this tool to calculate your semester GPA and your updated cumulative (overall) GPA based on credit hours.
If you leave both fields blank, the calculator returns your term GPA only.

What is an overall GPA?
Your overall GPA (also called cumulative GPA) is the weighted average of all grades you have earned across all completed courses. “Weighted” means courses with more credits count more than courses with fewer credits.
That’s why a 4-credit course has a larger impact on your GPA than a 1-credit course. This calculator follows that standard method.
How GPA is calculated
Step 1: Convert letter grades to grade points
Most schools use a 4.0 scale (some allow up to 4.3 for A+). The calculator uses this common conversion:
| Letter Grade | Grade Points |
|---|---|
| A+, A | 4.0 |
| A- | 3.7 |
| B+ | 3.3 |
| B | 3.0 |
| B- | 2.7 |
| C+ | 2.3 |
| C | 2.0 |
| C- | 1.7 |
| D+ | 1.3 |
| D | 1.0 |
| D- | 0.7 |
| F | 0.0 |
Step 2: Multiply grade points by credit hours
For each class: Quality Points = Credits × Grade Points.
Step 3: Add quality points and divide by total credits
Term GPA = (Total term quality points) ÷ (Total term credits)
Overall GPA = (Previous quality points + New quality points) ÷ (Previous credits + New credits)
Why students use an overall GPA calculator
- Plan scholarship eligibility requirements.
- Estimate admission competitiveness for internships or graduate school.
- Set realistic grade targets for the next semester.
- Track how a difficult course may affect cumulative performance.
How to use this calculator effectively
- Enter your current cumulative GPA and total completed credits (optional).
- Add all current term courses with credits and expected or earned grades.
- Click Calculate GPA.
- Review your term GPA and projected overall GPA instantly.
If you are planning ahead, try multiple scenarios (for example, one B+ versus one A-) to see where your final GPA could land.
Common GPA mistakes to avoid
1) Treating all classes equally
A 5-credit class and a 2-credit class do not affect GPA equally. Always weight by credits.
2) Forgetting repeated-course rules
Some schools replace the old grade when a class is repeated; others average both attempts. Check your registrar’s policy.
3) Ignoring non-GPA grades
Pass/Fail, Withdraw, and Incomplete grades may not count the same way. Your official school policy always overrides any generic calculator.
Tips for improving your cumulative GPA
- Prioritize high-credit courses where a higher grade has the biggest GPA effect.
- Use office hours and tutoring early, not after midterms.
- Break assignments into weekly milestones to avoid deadline stacking.
- Track your grade in each class every week to avoid surprises.
- Balance workload when registering: pair difficult classes with manageable ones.
Final note
This overall GPA calculator gives a fast, practical estimate and is ideal for planning. For official numbers used on transcripts, financial aid, honors, and graduation checks, always confirm with your institution’s academic records office.
