Test Score to Percentage Calculator
Convert a raw test score into a percentage, letter grade and grade point.
About Test Score to Percentage Calculator
The percentage is the net marks over the total, and letter grades then follow from institutional thresholds. Showing marks to the next grade makes the gap concrete rather than proportional. On a small test each mark carries several percentage points, so the same effort moves the grade far more than on a large examination.
Formula

Percentage = (marks earned − penalties) ÷ total marks × 100

Assumptions and limits
- The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, fees or charges or compounding frequency into account.
- Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
