Grade Calculator: Final Grade and Final Exam Calculator
Final grade calculator: your current class grade from weighted categories or points, the score you need on the final for a target, and whether it is possible.
Every convention this page applies is named in the result rather than assumed. Your numbers stay in this browser.

How to read this: the verdict describes how much room your numbers leave, not a decision or an offer. Change any input to see how much the result moves.
Assumptions and formula
With weighted categories, each category’s score is its points earned over its points possible, and the grade is those scores weighted by each category’s share, rescaled over the categories that have something graded. With total points, the grade is all points earned over all points possible. The letter is read from the scale you pick, after the rounding policy you pick is applied.
A category with nothing graded yet is left out of the current grade rather than counted as zero, so the figure is a score on the work marked so far. Sensitivity per outstanding assignment is measured by running the whole grade at full marks and at zero, which stays exact under drop-lowest rules and category caps.
Worked example
Homework worth 20% scored 17 of 20 (85%), a midterm worth 30% scored 85%, and a final worth 50% scored 92%. The grade is 85 × 0.2 + 85 × 0.3 + 92 × 0.5 = 17 + 25.5 + 46 = 88.5%, a B+ on the standard plus/minus scale. Earlier in the same term, with only the homework marked at 100%, the current grade is 100% of the work graded so far, not 20%.
Letter grade scale
The standard plus/minus letter grade scale used by many U.S. schools and the calculator's default. Your school or instructor may use different cut-offs; the calculator offers other common scales.
| Letter grade | Percentage |
|---|---|
| A+ | 97%–100% |
| A | 93%–96.99% |
| A- | 90%–92.99% |
| B+ | 87%–89.99% |
| B | 83%–86.99% |
| B- | 80%–82.99% |
| C+ | 77%–79.99% |
| C | 73%–76.99% |
| C- | 70%–72.99% |
| D+ | 67%–69.99% |
| D | 63%–66.99% |
| D- | 60%–62.99% |
| F | 0%–59.99% |
Schools differ in whether they round: some treat 89.5% as an A-, others need a full 90%. The calculator lets you choose how rounding works. Many colleges also do not give an A+, and some use a seven-point or ten-point scale instead.
When an assignment is worth more than others, work out the weighted average rather than a simple one: multiply each score by its weight, add them up, and divide by the total weight. A 95% on a final worth 40% moves your grade far more than a 95% on a quiz worth 5%.
Frequently asked questions
Final exam calculator: what do I need on my final to get the grade I want?
Take the target grade, subtract the part of it your current work has already secured, and divide what is left by the weight of the final. If the final is worth 30% and you are sitting on 85% in the other 70%, a 90 overall needs (90 − 85 × 0.7) ÷ 0.3, which is 101.7%, so a 90 is out of reach and an 88 (which needs 95%) is the realistic ceiling. This final exam calculator does that arithmetic for any weighting and tells you plainly when a target is no longer possible, so you can aim at one that is. A class grade calculator with weighted categories does the same sum for every remaining assignment, not only the final. The same page is a test grade calculator for a single score out of a total, and a weighted grade calculator when homework, quizzes and exams carry different shares of the final mark.
Does 89.5% round up to an A-?
It depends on your institution, which is why this page asks rather than deciding for you. Some schools round to the nearest whole percent, some promote anything within half a point of the next band, and many do not round at all. The raw percentage is shown next to the rounded one, and the page says when the policy is the only thing between two letters.
