What is a Grade Calculator?

A grade calculator is a free online tool that helps students calculate test scores, course grades, and weighted averages. This test grade calculator instantly converts your points earned into a percentage and letter grade, showing whether you achieved an A, B, C, D, or F. It's essential for tracking academic performance and planning study strategies.

Our final grade calculator also supports weighted averages, allowing you to calculate your overall course grade when different assignments have different weights. Whether you need to calculate test scores, determine your final grade, or figure out what you need on an upcoming exam, this calculator provides accurate, instant results.

How to Calculate Your Grade

1

Simple Grade Calculation

Divide your score by the total points, then multiply by 100 to get the percentage. For example: 45 out of 50 = (45 ÷ 50) × 100 = 90% (A grade).

2

Weighted Grade Calculation

Multiply each grade by its weight, add all results, then divide by total weight. For example: Test 1 (80%, weight 30%) + Test 2 (90%, weight 70%) = (80×0.30) + (90×0.70) = 87%.

3

Convert to Letter Grade

Compare your percentage to the grading scale. Standard scale: A (90-100%), B (80-89%), C (70-79%), D (60-69%), F (below 60%).

Tips for Improving Your Grades

Review Regularly

Don't wait until exam time. Review notes daily or weekly to retain information better.

Practice Tests

Take practice tests to familiarize yourself with question formats and identify weak areas.

Ask Questions

Don't hesitate to ask teachers for clarification on concepts you don't understand.

Time Management

Create a study schedule and stick to it. Prioritize assignments based on weight and deadlines.

Submit All Assignments

Never skip assignments. Even partial credit is better than zero, which can significantly hurt your grade.

Frequently Asked Questions About Grade Calculator

How do I calculate my grade percentage?

To calculate grade percentage, divide your earned points by the total possible points, then multiply by 100. For example: if you scored 85 out of 100, your percentage is (85 ÷ 100) × 100 = 85%. Use our grade calculator to get instant results.

What letter grade is 85 percent?

An 85% is typically a B grade on the standard grading scale. The standard scale is: A (90-100%), B (80-89%), C (70-79%), D (60-69%), F (below 60%). Some schools use +/- grades where 85% would be B (83-86%).

How do you calculate weighted grades?

To calculate weighted grades, multiply each grade by its weight percentage, add all results together, then divide by the total weight (usually 100%). For example: Test 1 (80%) weighted 30% + Test 2 (90%) weighted 70% = (80×0.30) + (90×0.70) = 24 + 63 = 87%.

What grade do I need on my final to pass?

To find the grade needed on your final, use this formula: Required Final Grade = (Desired Grade - Current Grade × (1 - Final Weight)) ÷ Final Weight. For example, if you have 75% average, want 80% overall, and final is 30%: (80 - 75×0.7) ÷ 0.3 = 91.67%.

Is D a passing grade?

Whether D is passing depends on the institution and course. Most colleges consider D (60-69%) as passing but may not count toward major requirements or GPA. Some schools require C (70%+) to pass. High schools typically accept D as passing. Check your school's specific policies.

How accurate is this grade calculator?

Our grade calculator is 100% accurate using standard mathematical formulas for percentage and weighted average calculations. Results match what teachers use for grading. However, grading scales may vary by institution, so confirm your school's specific scale.
