Grade Calculator
Calculate weighted grades and target scenarios.
What grade do I need on the final?
The mark you need is the target overall grade minus the weighted marks you already have, divided by the weight left.
Formula: Course points = score × weight. Current grade divides earned course points by completed weight; target score solves the remaining weighted portion.

What this calculator does
Add graded items and weights to find the current grade and score needed on remaining work.
Use it to turn Graded items, Target final grade into a checked result you can compare, copy, or rerun with different assumptions.
The page shows the formula, a numeric worked example, and the assumptions that affect this everyday calculation.
Inputs and what they mean
- Graded items
- — list of values value.
- Target final grade
- — number value.
How to use it
- Enter the requested values.
- Adjust optional assumptions for your situation.
- Review the result and detailed breakdown.
Formula
Course points = score × weight. Current grade divides earned course points by completed weight; target score solves the remaining weighted portion.
Inputs used: Graded items, Target final grade.
Edge handling: Graded items is required.; Target final grade is required.; Target final grade must be at least 0.; Target final grade must be no more than 100..
Worked example
Homework and midterm
- Start with Graded items: [{"label":"Homework","first":"85","second":"40"},{"label":"Midterm","first":"90","second":"30"}], Target final grade: 90.
- Apply the method: Course points = score × weight. Current grade divides earned course points by completed weight; target score solves the remaining weighted portion.
- Combine completed weighted scores and estimate what is needed on the remaining work.
Reading the result
The headline figure is the main answer. Any breakdown underneath shows the parts that make it up, so you can check the working and see what changes when you adjust an input.
Limitations and assumptions
- Inputs outside the supported range are rejected rather than forced into a result.
- The result depends on the values you enter for this grade calculator; it does not supply missing rates, rules, prices, dates, or assumptions for you.
Common questions
What grade do I need on the final?
The mark you need is the target overall grade minus the weighted marks you already have, divided by the weight left. Check the formula, example, and limitations on this page before using the result for a real everyday decision.
Must weights total 100%?
Completed items may total less than 100%; the calculator treats the rest as remaining work. Check the formula, example, and limitations on this page before using the result for a real everyday decision.
Can extra credit exceed 100%?
Scores up to 200% are supported, but item weights remain between 0% and 100%. Check the formula, example, and limitations on this page before using the result for a real everyday decision.
How do I use the Grade Calculator?
Enter the required values for Graded items, Target final grade. The calculator applies the formula on this page and shows the main result with any supporting breakdown so you can check the arithmetic.
What formula does the Grade Calculator use?
Course points = score × weight. Current grade divides earned course points by completed weight; target score solves the remaining weighted portion. The visible formula section above lists the calculation path and the edge cases the page handles, so the result can be checked without relying on the form alone.
Can the Grade Calculator be used for exact decisions?
Use it as a calculation aid, not as a substitute for checking the underlying rule, contract, policy, or professional advice that applies to your situation. When a result depends on local rules, personal details, prices, or dates, enter those values yourself and confirm them before acting.
