Grade Calculator
Use this free weighted grade calculator to find your current grade in any course and to work out the score you need on the final exam to hit a target. Enter each graded component (quizzes, midterms, homework, projects) with the percentage score you got and the weight that component carries. The calculator returns your weighted current grade, the total weight entered, and a clear answer for what you need on the final.

What do I need on my final?
The math is exact: given the scores and weights you enter, the current grade and final-exam target are calculated by standard weighted-average formulas. Real-world accuracy depends on entering the weights correctly from your syllabus. If your instructor applies a curve or extra credit, factor that in after the calculator's base answer.
Everything you need for grade planning
Six features that cover weighted grades and final-exam planning.
Weighted average
Each item is weighted by its share of the final grade, so a 30 percent midterm pulls more than a 5 percent quiz, exactly as the syllabus intends.
What-do-I-need-on-the-final
Tells you the minimum final-exam score required to hit any target overall grade, with clear flags when the target is unreachable or already secured.
Running weight total
Shows how much of the 100 percent weight you have entered so far, helping you spot a missing component.
Unlimited items
Add or remove graded components as needed. Works for high school, university, and online courses with weighted grading.
100% private, runs in browser
Your scores and weights stay on your device. Nothing is sent to a server, logged, or shared.
Mobile-friendly layout
Clean responsive design that works on phones, tablets, and desktops.

About weighted grades
A clear guide to the weighted-average formula and final-exam planning.
What is a weighted grade?
A weighted grade is one where different components count for different shares of the final grade. A typical syllabus might say homework is 20 percent, quizzes 10 percent, the midterm 30 percent, and the final 40 percent. Multiplying each score by its weight and summing the result gives the overall weighted grade. Almost every university course uses weighted grading because instructors want to put more emphasis on bigger assessments.
The weighted-average formula
The formula is straightforward: weighted grade equals sum of (score times weight) divided by sum of weights. If you have entered scores for items whose weights add up to less than 100 percent, the formula still works as a partial average of what is done so far. The calculator shows the running total of weight you have entered so you can tell at a glance how much of the course remains.
What do I need on the final?
The classic question, and the headline feature of this calculator. The math is: (target grade times 100 minus weighted points already earned) divided by the weight of the final. If the answer is between 0 and 100, that is the minimum score you need on the final. If it is above 100, the target is not achievable from your current standing. If it is below 0, the grade is already secured.
Setting a realistic target
Pick a target letter grade and look up its lowest percentage in your syllabus. Common cut-offs are A at 90, B at 80, C at 70. Use that as the desired grade. The calculator tells you what the final exam score must be. If the number looks intimidating, try the next-lower letter grade and see if it becomes achievable. Setting a realistic target is often more motivating than chasing a stretch one.
Weights that do not add up to 100
Some instructors use point totals rather than percentages, where the points naturally do not sum to 100. The calculator works either way as long as you are consistent. If you mix percent and points, convert one set to match the other before entering. The "weight total" indicator under the table helps you spot a missing component if the running total is unexpectedly low.
Extra credit and curves
Extra credit is straightforward if your instructor told you the weight: add a row with the score and weight. Curves are different because they remap weighted percentages to letter grades or shift the percentages by a fixed amount. Use the calculator to find the raw weighted percentage and then apply the curve as your instructor describes it.
Why the calculator splits current grade from the final-exam helper
The current-grade panel uses only the items you have already entered, so it answers the question "where do I stand right now?" The final-exam helper asks a separate question: "given what I have, what score do I need on the one remaining final exam to hit my target?" Both use the same data but they answer different questions, so they appear in separate result blocks.
Tracking grade through the term
Bookmark the page and update it as each new grade comes back. The pattern of changes tells you whether your study strategy is working. If your weighted average is rising, keep going. If it is flat or falling, that is a signal to change something (more practice problems, office hours, study group) before the final.
When the calculator is most useful
The week before the final exam is the moment most students turn to a grade calculator. You can see exactly what score you need, and the result calibrates how seriously to take revision. A 60 percent target on a hard exam feels very different from a 95 percent target on the same exam. Either way you know what you are aiming for and can plan study time to match.
Frequently asked questions

It multiplies each score by its weight (as a percentage of the final grade), sums the products, and divides by the total weight you have entered. For example, a 90 worth 30 percent and an 80 worth 70 percent gives (90*30 + 80*70) / (30+70) = (2700+5600)/100 = 83. The calculator runs this formula live as you fill in the table.
It works out the minimum score you need on the final exam to hit a target overall grade. The formula is (desired*100 minus the weighted points already earned) divided by the weight of the final. If the answer is above 100 you cannot reach the target. If it is below 0 you have already secured the grade regardless of the final.
For the current-grade calculation no, because the calculator normalises by the total weight you entered. But for the "what do I need on my final" feature, weights should add up to 100 percent, with the final exam treated separately. The note under the table shows the running total of weights so you can spot a mismatch.
Either is fine as long as you are consistent. If quizzes total 200 points and the final is 300 points, enter 200 and 300 (the calculator will treat the implied weights correctly). Alternatively convert to percent: quizzes 40 percent, final 60 percent. The weighted average comes out the same either way.
Yes. Add an extra-credit row with the points or percent score and the weight your instructor told you it carries. Some instructors apply extra credit by simply adding a number to the final grade rather than as a weighted component; if so, calculate the weighted grade first, then add the bonus afterwards.
An unweighted grade is the simple average of all your scores. A weighted grade accounts for the fact that the final exam often counts more than a quiz. Almost every university and senior school course uses weighted grades, so use this calculator rather than a simple average for any course with a syllabus that lists percentages.
Click "Add item" to insert a row at the bottom and the × button to remove a row. Use one row per graded component listed in your syllabus: each quiz, homework set, midterm, project, and the final exam separately. The calculator updates instantly so you can see what changing one score does to the overall.
If your accumulated weighted points already place you well below the target, even a perfect 100 on the final cannot pull you up enough. The "Not achievable" badge appears in that case. Either lower your target or talk to your instructor about extra credit or grade buckets that might still be open before the final.
If you have accumulated enough weighted points that even a 0 on the final keeps you at or above the target, the calculator says "Already secured" and shows a needed score of 0 (or below). This is good news. You may still want to take the final seriously, but you will hit the target either way.
No. The calculator works with raw weighted percentages. A curve usually adjusts those percentages by a fixed amount or remaps them to a letter grade scale. Use the calculator to estimate your raw weighted percentage and then apply the curve as your instructor describes it.
The math is exact: given the scores and weights you enter, the needed final score is correct. The prediction's real-world accuracy depends on the accuracy of the weights you entered (matching the syllabus) and on the assumption that no further graded components are still to come other than the final.
Yes. The math works for any course that weights different components. High school courses often use a simple split (tests 70 percent, homework 30 percent), which fits the calculator perfectly. Some teachers use a points-only model instead of percentages; either works as long as you use it consistently.
Yes. Your scores and weights stay in your browser. Nothing is sent to a server, logged, or shared. You can use the calculator without an account and even offline once the page has loaded.
