Grade improvement calculator
Measure the movement from “previous grade” to “new grade”. The answer shows the relative increase or decrease and uses the first value as the starting point.
grade improvement calculator: Compare two equivalent values and measure their change.

How to calculate it
Subtract previous grade from new grade, divide the difference by the absolute starting value, and multiply by 100. A negative sign means a decrease.
- Insert the values in the formula, perform the division first, and round only the final answer.
- A positive answer indicates growth and a negative answer indicates a reduction. The percentage is measured against the starting value.
Applied example
When previous grade moves from 70 points to 75.6 points, the percentage change is 8%.
Subtract previous grade from new grade, divide the difference by the absolute starting value, and multiply by 100. A negative sign means a decrease. A positive answer indicates growth and a negative answer indicates a reduction. The percentage is measured against the starting value.
Practical use
Turn points or correct answers into a percentage grade.
For exam grades, use “previous grade” as the reference. It must represent the full set or the starting point of the comparison.
Checks that matter
- If questions have different weights, use awarded points instead of simply counting answers.
- Do not treat the absolute difference as a percentage; divide it by the starting value first.
- Keep full precision during the calculation and round only the final answer to match the accuracy of the source data.
Frequently asked questions
What is the correct reference value?
For exam grades, use “previous grade” as the reference. It must represent the full set or the starting point of the comparison.
Can the answer be greater than 100%?
Yes. This happens when the part exceeds the total or the final value is more than double the starting value.
How many decimal places should I use?
