Raise GPA Calculator
Find the GPA you need from now on to reach your target cumulative GPA.
StudentsYou must average 4.00 across your next 30 credits to reach 3.40.
Raising a cumulative GPA is a weighted-average problem with one unknown: the GPA you must earn on your remaining credits. Enter where you stand now, how many credits you have completed, the GPA you want, and how many credits you plan to take, and this calculator solves for the required average. If the required GPA is above the maximum your scale allows, it says so directly and shows the highest cumulative GPA still reachable.
How to use the Raise GPA Calculator
- Enter your current cumulative GPA.
- Enter how many credits you have completed.
- Enter your target cumulative GPA.
- Enter how many credits you plan to take, then read the GPA you need to earn on them.
Formula
Total Credits = completed + planned. On a 4.0 scale a required GPA above 4.0 means the target cannot be reached within the planned credits; more credits or a lower target are needed.
Worked example
You hold a 3.10 GPA over 60 completed credits and want 3.40, with 30 credits planned. Required = (3.40 x 90 - 3.10 x 60) / 30 = (306 - 186) / 30 = 4.00. You would need straight As for all 30 credits. Extending the plan to 45 credits lowers the requirement to (3.40 x 105 - 186) / 45 = 3.80, demanding but realistic.
Good to know
The mathematics of raising a GPA is unforgiving late in a degree, because completed credits anchor the average. The same effort moves a first-year GPA dramatically and a senior GPA by hundredths. That is not a reason to give up; it is a reason to set targets in the range the equation allows, and to remember that employers and graduate schools also read trends: a final year at 3.8 on top of a 3.2 record tells its own story even where the cumulative number lands.
US grading scale reference
The table below is the US plus/minus scale used across this site. Where this tool offers other scales, the Canadian scale sets an A from 85% with a pass at 50%, and the Australian scale uses the bands HD (85%+), D (75-84%), C (65-74%), P (50-64%) and F (below 50%) on a 7.0 GPA.
| Letter grade | Percentage | GPA points |
|---|---|---|
| A+ | 97–100% | 4.0 |
| A | 93–96% | 4.0 |
| A- | 90–92% | 3.7 |
| B+ | 87–89% | 3.3 |
| B | 83–86% | 3.0 |
| B- | 80–82% | 2.7 |
| C+ | 77–79% | 2.3 |
| C | 73–76% | 2.0 |
| C- | 70–72% | 1.7 |
| D+ | 67–69% | 1.3 |
| D | 63–66% | 1.0 |
| D- | 60–62% | 0.7 |
| F | 0–59% | 0.0 |
Frequently asked questions
How can I raise my GPA fast?
The levers are only the grades and credits still ahead of you. Run the numbers here: the fewer credits you have completed, the more each strong semester moves the cumulative figure.
What if the required GPA is above 4.0?
The target is not reachable in the planned credits. The calculator shows your maximum reachable GPA if you earn straight As, and adding more planned credits lowers the requirement.
How much does one A raise a 3.0 GPA?
It depends on credits completed. After 90 credits, one 3-credit A moves the cumulative GPA by about 0.03. After 15 credits, the same A moves it by about 0.17.
Should I retake a class to raise my GPA?
If your institution replaces the original grade, retaking a D or F in a high-credit course is often the single biggest lever available. If both attempts average, the benefit halves. Check the repeat policy first.
Can I reach a 3.5 from a 3.2 in one semester?
Enter your figures: with 75 credits done and 15 planned at a required (3.5 x 90 - 3.2 x 75) / 15 = 5.0, no. The calculator will show the realistic ceiling, about 3.33 with straight As.
