Test Curve Calculator
Enter your raw test score and the number of curve points added to see your final curved score.
Test Curve Calculator
Applies a flat point curve to a raw test score, capped at a maximum of 100%.
This calculator applies the simplest and most common type of grade curve — adding a flat number of points to a raw score — while correctly capping the final result at 100% since a curved score generally shouldn't exceed the maximum possible. It's handy for students checking how a curve announced by an instructor affects their specific score, or for instructors quickly previewing the effect of a proposed curve.
Example
- With the default values shown above, this calculator returns: Curved Score ≈ 73%.
Frequently Asked Questions
Why is the curved score capped at 100%?
Because a score generally can't exceed the maximum possible, the calculator caps the final curved result at 100% even if adding the curve points would otherwise push it higher.
Is this the only way instructors curve grades?
No — a flat point curve (adding the same number of points to everyone) is just one common method; other curving methods (like scaling to the top score, or a bell-curve adjustment) work differently and would need a different calculation.
