A grade calculator turns scattered scores into one clear number, so you always know where you stand. Enter what you have earned, add the weight of each assignment, and this free grade calculator shows your percentage, letter grade and GPA points in seconds. You can also work backwards with the final grade calculator and find out what you need on the final exam to reach the grade you want.
Most courses do not count every score equally, which makes mental maths unreliable. This page explains how this calculator works, shows the formulas, walks through three worked examples and answers common questions. Everything runs in your browser, with no sign-up and no data sent anywhere, so you can open the calculator and start typing straight away.

Free, private and 100% browser-based. Nothing you type leaves your device.
Pick the scale your school uses. Letter cut-offs differ between schools.
Custom scale: enter the minimum percentage for each letter and its GPA points. Include a row starting at 0.
Total points earned divided by total points possible. Every point counts equally. Use Add row for more scores.
Use Add assignment for more rows. Leave a row empty to ignore it. Weights are percentages of the whole course and should add up to 100.
Your current grade is the grade you have in the part of the course before the final.
Results are estimates. Grading rules and cut-offs differ by school, so check your syllabus.
What Is the GetFuturix Grade Calculator?
The GetFuturix grade calculator is a free online tool with three modes. You switch between them with the tabs above the form, and the grade scale selector applies to all three, so every mode of this calculator shows letters and GPA points the same way.
- Weighted grade: in the weighted grade calculator mode you add each assignment with the score you earned, the score possible and its weight. The calculator returns your current weighted grade, your letter grade, your GPA points and a warning if your weights do not add up to 100%.
- Final grade needed: the final grade calculator mode asks for your current grade, your target grade and the weight of the final exam. It tells you the score you need, or says plainly that your target is already secured or out of reach.
- Simple average: add up your points earned and your points possible. Every point counts equally, which makes this the quickest grade calculator mode for courses that are graded on total points.
Because the page works as a weighted grade calculator and a final grade calculator in one place, you do not need a separate tool for each job. It also doubles as a quick final exam calculator. Together the three modes make a complete grade calculator for the whole term.
How to Use the Grade Calculator, Step by Step
The steps below cover each mode of the grade calculator. Whichever mode you pick, start by choosing a grade scale from the drop-down menu.

Weighted Grade Calculator Formula Explained
A weighted grade gives the bigger parts of a course more influence. The idea is simple: turn each score into a percentage, multiply it by its weight, add the results and divide by the total weight.
Score percentage = points earned ÷ points possible × 100
Weighted grade = (percentage 1 × weight 1 + percentage 2 × weight 2 + …) ÷ total weight
The weighted grade calculator applies these two formulas to every row you enter, then shows each row’s contribution so you can see where your grade comes from.
Why use a weighted grade calculator instead of a plain average? A plain average treats a 5% quiz and a 40% exam as equals, which the syllabus never does. A weighted grade calculator follows the weights you were given, so a strong exam can lift your result and a weak project can pull it down by the right amount.
When your weights add up to 100, dividing by the total weight changes nothing. When they do not, the division scales the result so it still reads as a percentage of the work you entered. That is why a good weighted grade calculator warns you about the total instead of silently guessing what you meant.
A weight of 25% means that item supplies one quarter of your final grade, so a 90% score on it adds 22.5 points. The results table shows this in its “Counts toward grade” column, which makes a grade calculator more useful than a plain average.
Final Grade Calculator: The Score You Need on the Exam
The final grade calculator mode rearranges the weighted average to solve for the missing score, which makes it the most useful grade calculator feature in exam season. Suppose your current grade covers everything before the final, and the final exam is worth a fraction w of the course. Then:
Required score = (target − current × (1 − w)) ÷ w
Here w is the final exam weight as a decimal, so 30% becomes 0.30. The part current × (1 − w) is what you have already banked. The final must supply the rest of the gap, and dividing by w turns that gap into a score on the exam itself.
Three outcomes are possible. If the required score is 0 or below, your target is already secured, because even a zero on the final would not pull you under it. If it is above 100, you would need extra credit to reach the target, and the final grade calculator shows the highest grade you can still reach. Anything in between is the score to aim for.
Many students search for a final exam calculator when all they want is one number: the score they need on the last paper. The final grade calculator gives that number, and it also tells you when no score would be enough, so you can plan revision around a realistic target.
Worked Example 1: Weighted Grade Calculator for a Four-Part Course
A student has four graded parts, and the weights add up to 100%. Here is how the weighted grade calculator handles them.
| Assignment | Score | Percentage | Weight | Counts toward grade |
|---|---|---|---|---|
| Homework | 45 / 50 | 90.00% | 20% | 18.00 |
| Lab reports | 84 / 100 | 84.00% | 25% | 21.00 |
| Midterm | 68 / 80 | 85.00% | 25% | 21.25 |
| Project | 76 / 100 | 76.00% | 30% | 22.80 |
| Total | 100% | 83.05% |
Add the last column: 18.00 + 21.00 + 21.25 + 22.80 = 83.05. The weighted grade calculator therefore reports 83.05%. On the US scale with plus and minus, 83 is the lowest mark for a B, so the result is a B worth 3.0 GPA points. The project has the lowest percentage but the largest weight, which is exactly the kind of detail a weighted grade calculator is built to show.
Worked Example 2: Final Grade Calculator Scenarios
A student has 84% going into the final, and the final is worth 35% of the course. The table shows what the final grade calculator returns for three different targets.
| Target | Calculation | Score needed | Verdict |
|---|---|---|---|
| 80% | (80 − 84 × 0.65) ÷ 0.35 | 72.57% | Possible |
| 85% | (85 − 84 × 0.65) ÷ 0.35 | 86.86% | Possible, but needs a strong exam |
| 90% | (90 − 84 × 0.65) ÷ 0.35 | 101.14% | Out of reach without extra credit |
Here 84 × 0.65 = 54.60 is the part of the grade already banked. For the 90% target the final grade calculator also reports the best case: a perfect 100% on the final gives 54.60 + 35 = 89.60%, so 90% cannot be reached.
Now flip the situation. With a current grade of 95%, a target of 70% and a final worth 20%, the final grade calculator gives (70 − 76) ÷ 0.2 = −30. A negative requirement means the target is secured, and a 0% on the final would still leave the student at 76%. Comparing targets side by side like this is easy with a final grade calculator.
Worked Example 3: Simple Average Grade Calculator
A course graded on total points has four tests, which suits the simple mode of the calculator.
| Test | Points earned | Points possible | Percentage |
|---|---|---|---|
| Test 1 | 18 | 20 | 90.00% |
| Test 2 | 27 | 30 | 90.00% |
| Test 3 | 40 | 50 | 80.00% |
| Test 4 | 9 | 10 | 90.00% |
| Total | 94 | 110 | 85.45% |
The calculator’s simple average is 94 ÷ 110 = 85.45%, which is a B on the US scale. Averaging the four percentages instead gives (90 + 90 + 80 + 90) ÷ 4 = 87.50%, which would be a B+. The difference appears because Test 3 was worth more points. Use the points-based grade calculator mode only if your instructor grades by total points, and use the weighted grade calculator if your syllabus lists percentage weights.
Grade Scale Tables Used by the Calculator
The calculator includes two built-in scales and a custom option. The cut-offs below are common in the United States and feed the weighted grade calculator’s letter grades, but schools set their own, so compare them with your syllabus or student handbook.
| US letter grade | Minimum percentage | GPA points |
|---|---|---|
| A+ | 97% | 4.0 |
| A | 93% | 4.0 |
| A− | 90% | 3.7 |
| B+ | 87% | 3.3 |
| B | 83% | 3.0 |
| B− | 80% | 2.7 |
| C+ | 77% | 2.3 |
| C | 73% | 2.0 |
| C− | 70% | 1.7 |
| D+ | 67% | 1.3 |
| D | 63% | 1.0 |
| D− | 60% | 0.7 |
| F | 0% | 0.0 |
The 4.0 scale without plus and minus is simpler:
| Letter grade | Minimum percentage | GPA points |
|---|---|---|
| A | 90% | 4.0 |
| B | 80% | 3.0 |
| C | 70% | 2.0 |
| D | 60% | 1.0 |
| F | 0% | 0.0 |
Choose the custom scale in the calculator if your school uses different cut-offs or a different point system. Enter the minimum percentage, the letter and the GPA points for each row, and include a row that starts at 0 so every score has a grade. Pick the scale before you press Calculate, because all three modes use it to assign letters and GPA points.
Tips for Getting Accurate Results From the Calculator
These habits help you get more accurate answers from any grade calculator, and especially from a weighted grade calculator, where one wrong weight changes the result.
- Copy weights from your syllabus. A grade calculator is only as accurate as the numbers you give it, so use the exact percentages.
- Keep categories consistent in the weighted grade calculator. If homework is one category worth 20%, enter one combined homework row at 20%, or enter each homework item with weights that add up to 20%.
- Check for dropped scores. The grade calculator does not drop your lowest score automatically, so remove that item yourself if your instructor drops it.
- Enter finished work only. In the weighted grade calculator, leave future assignments empty and the result is your grade so far.
- Run what-if scenarios. Change one score or one target in the grade calculator and calculate again to see how much a single assignment moves your grade.
- Aim for the edge of a letter. If you want a B on the US scale, enter 83 as your target in the final grade calculator, the lowest percentage that still counts as a B.
- Test several targets. Run the final grade calculator for 80, 85 and 90 to see how quickly the required score climbs.
- Calculate often. Re-run the grade calculator after each graded item so surprises never wait until the end of term.
Common Grade Calculator Mistakes to Avoid
Most wrong answers from a grade calculator come from typing errors rather than from the maths.
- Weights that do not total 100. If the weights add up to 80 or 120, the weighted grade-calculator scales the grade and shows a warning. Check the syllabus before trusting the number.
- Mixing points and percentages. If you enter 90 as the score earned, enter 100 as the score possible. Do not type a percentage in one box and raw points in the other, because the weighted grade calculator treats the two boxes as a fraction.
- Using the wrong current grade. In the final grade calculator, your current grade should be the percentage you hold before the final, not a share of the whole course.
- Typing the final weight as a decimal. Enter 30, not 0.3. The final grade-calculator expects percentages.
- Forgetting extra credit or dropped scores. Both change the result, and the grade-calculator only knows what you type.
- Treating a grade calculator result as official. Only your instructor or registrar can confirm a grade.
Who Is This Calculator For?
Anyone who gets graded can use it. High school and college students in the United States work with letter grades and GPA points. Students in the UK often think in percentages and degree classes. Students in Pakistan and across South Asia may see percentages, marks or a 4.0 GPA depending on the institution. The custom scale lets one grade-calculator fit all of these.
Parents can check progress halfway through a term, tutors can set realistic targets with a student, and teachers can test a weighting scheme in the weighted grade calculator before publishing it. A final grade calculator is also handy for planning study time before exams. Once you know your course grades, open the Global CGPA & GPA Calculator to turn them into a semester or cumulative GPA.
Privacy: Everything Runs in Your Browser
The scores, weights and targets you type are not uploaded, saved on a server or tied to an account, so even a weighted grade -calculator full of private scores stays on your device. There is no sign-up, and closing the page clears what you entered.

Frequently Asked Question
How do I calculate my grade with a grade calculator?
Choose a mode, enter your scores and press Calculate. In the weighted grade-calculator you add the score earned, the score possible and the weight of each assignment. The grade-calculator converts every score to a percentage, applies the weights and returns your grade, letter and GPA points. Weights should add up to 100% for the most accurate result.
What is a weighted grade and how does a weighted grade calculator use it?
A weighted grade is an average in which some scores count more than others. A final exam worth 30% affects your result far more than a quiz worth 5%. To work it out, multiply each percentage by its weight, add the results and divide by the total weight. A weighted grade-calculator does these steps for you.
How does the final grade calculator work?
The final grade-calculator uses the formula (target − current × (1 − weight)) ÷ weight. You enter your current grade, your target and the final exam weight. The final grade-calculator works out the score you must reach on the exam, or tells you the target is already secured or cannot be reached without extra credit.
What happens if my weights do not add up to 100% in the weighted grade calculator?
The weighted grade-calculator still gives a result, but it shows a warning with your actual total. If the weights add up to less than 100%, the result is your grade so far, scaled to 100%. If they add up to more than 100%, the result is scaled down, so please check your syllabus for typing mistakes.
What does “target already secured” mean in the final grade calculator?
It means the grade you want is guaranteed, even if you score zero on the final exam. The points you have already banked are enough on their own. The final grade-calculator shows what your grade would be with a zero, so you can see how much room you have. Always confirm any special rules with your instructor, because every grade-calculator relies on the numbers you enter.
Can I reach my target in the final grade calculator if the score needed is above 100%?
Not unless your instructor offers extra credit. A required score above 100% means even a perfect exam falls short. The final grade-calculator then shows the highest grade you can still reach with a perfect score, so you can choose a realistic new target or ask your teacher whether extra credit exists.
Which grade scale should I choose?
Choose the scale that matches your school’s handbook. In this grade-calculator, the US A–F scale with plus and minus is the most detailed built-in option, and the 4.0 scale is simpler. If your cut-offs differ, pick the custom scale and enter your own percentages, letters and GPA points. Letter cut-offs vary from school to school.
Does this weighted grade calculator work for UK or Pakistani grading?
Yes, the grade-calculator works in two ways. The percentage from the weighted grade-calculator works with any system that reports percentages. For letters or GPA points, choose the custom scale and copy the cut-offs from your university’s handbook. Because grading rules differ between institutions, the built-in scales are only a starting point and results are estimates. The final grade-calculator mode works the same way for any percentage-based course. Check Grading System by Country
Is my data saved or shared?
No. The grade-calculator runs entirely in your browser, so nothing you type into the final grade-calculator or any other mode is sent to a server, stored in an account or shared with anyone. There is no sign-up. When you close or refresh the page, your entries disappear. The copy and print buttons only use features built into your browser.
Are the results official?
No. The results from the weighted grade-calculator, the final grade calculator and the simple mode are estimates based on the numbers you enter and the grade scale you select. Schools handle rounding, dropped scores, extra credit and cut-offs differently, so your official grade may vary. Use the grade calculator for planning, and check final results with your instructor or your school’s records.
A note on accuracy: grading rules differ by school and by instructor, and every result from this grade calculator is an estimate. Always confirm your official grade with your instructor or your school’s records.
Conclusion: Know Your Grade Before the Final
A reliable grade calculator removes the guesswork from a busy term. Use the weighted mode to see where you stand today, the final grade mode to set a realistic target for the exam, and the simple average when a course is graded on total points. Whether you need a weighted grade calculator for a multi-part course or a final grade calculator to plan your revision, the grade calculator gives you a clear answer in seconds, privately and for free.
Try the example, enter your own numbers in the weighted grade calculator and see what your next assignment could change. Run the final grade calculator again after each graded item to keep your target realistic. If you want to go one step further, the CGPA and GPA calculator can turn your results into a cumulative GPA.
