See your cumulative grade from previous and current grades, what can change your average, and whether your target outcome is still on track.
A cumulative grade calculator combines prior and current weighted performance so you can track trend direction and the score needed to reach your next threshold.
For scenario reinforcement, compare with Midterm Grade Calculator, Weighted Grade Calculator and validate assumptions in Cumulative Grade Checklist: What Risk Can Change Your Result?.
Use this cumulative grade calculator to calculate cumulative grade from previous and current grades and see your combined average. Enter your prior average, current term performance, and their respective weights or credits to get an exact cumulative result. This helps you understand whether a strong or weak term meaningfully shifts your overall position or if your past performance limits short-term change. Use this result to assess trend direction, identify risk, and decide whether your current trajectory still supports your target grade. For term-level comparison, use this page after running the Semester Grade Calculator.
A new term has less impact when your existing credit base is large, even if the new result is strong or weak. Significant changes usually require either a high-credit term or a result far from your current average. Use the calculator to test whether your latest performance materially shifts your overall trajectory.

Formula Used by This Calculator
Use the calculator formula with confirmed inputs to compute cumulative grade calculator.
Formula: cumulative_percent = (prev_avg*prev_credits + current_avg*current_credits) / total_credits
Example: enter known scores and weights
Complete these steps in order to get a reliable result.
Output: Previous 72% across 60 credits plus current 85% across 30 credits gives a cumulative grade of 76.3%.
Output: Previous 76% across 120 credits plus current 82% across 10 credits gives a cumulative grade of about 76.5%.
Used in this scenario
Output: Previous 78% across 60 credits plus current 66% across 60 credits gives a cumulative grade of 72%.
Used in this scenario
Output: Previous 65% across 30 credits plus current 75% across 30 credits gives a cumulative grade of 70%.
Used in this scenario
Output: Previous 75% across 90 credits plus current 82% across 10 credits gives a cumulative grade of 75.7%.
Used in this scenario
Output: Previous 69% across 80 credits plus current 75% across 20 credits gives a cumulative grade of 70.2%.

Avoid these input and interpretation errors before acting on the result.
Interpret your result quickly, then validate assumptions before acting.
Use the Cumulative Grade Calculator when several completed terms, courses, or grading periods need to be combined into one running result.
Enter each confirmed grade with the correct weight or credit value so larger components influence the cumulative result appropriately.
Use the output to decide whether the next grade target should be tested with a semester, weighted-grade, or what-if calculator.
Label each entry as completed, current, transfer, archived, or forecast before combining records.
Cumulative planning is strongest when historical records stay separate from current forecasts. Enter completed terms as fixed inputs, then model current or future work in a separate step before combining it. This makes it easier to explain whether a change in the cumulative result came from new performance, credit weighting, or a corrected historical entry.
Use this model when your grade is built from multiple weighted components across a term. Enter each component with its percentage weight and current or projected score. Check whether weights sum to 100% and then use scenario changes to see how one category shift changes your final position.

Use this calculator when you have a previous average and a current term result that need to be combined into one cumulative grade.
The calculator weights each part by credits, terms, or percentage contribution. A previous average based on many credits will usually change slowly, while a current result with high credit value can move the cumulative grade more.
For example, a strong current term may only slightly improve your cumulative grade if your completed credit base is already large. A weak current term can matter more if it carries equal or higher weight than your previous work.

Compare the new cumulative grade with your previous cumulative average. The difference shows whether your current term materially changed your overall position.
If the movement is small, your past performance is limiting short-term change. If the movement is large, the current term has enough weight to affect your target, classification, scholarship, or progression outcome.
Use the result to decide whether your current trajectory is stable, improving, or at risk.

Do not average previous and current grades equally unless they carry equal credits or equal weighting.
Do not ignore repeated-course, transfer-credit, or excluded-credit rules. These policies can change the cumulative result even when the arithmetic is correct.
If you need to calculate the current term first, use the Semester Grade Calculator before entering the result here.

Multiply each grade by its credit or weight, add the weighted values, then divide by the total credits or weights.

A large completed credit base reduces the impact of new grades, even when the current term is strong.

Yes, but the effect depends on how many credits the term carries compared with your previous completed credits.
Yes. A weak term can lower your cumulative grade, especially if it has equal or high credit weight.
Use the weighting system your school uses, but keep the same method across previous and current results.
Yes. Use projected current-term values, but treat the result as a scenario until marks are confirmed.
Policies vary. Some replace the old grade, some average attempts, and some cap repeat results.
Include transfer credits only if your institution counts them in the cumulative grade calculation.
Compare the new cumulative result with your previous cumulative average and track the direction over time.
Recalculate after each term, grade correction, repeat-course update, or credit-weighting change.
Use the Semester Grade Calculator for current-term results or the Credit-weighted Average Calculator for detailed credit weighting.
