Marks Percentage Calculator

Spluxly’s free online Marks Percentage Calculator is a versatile and student-friendly academic performance tool designed for students, teachers, and parents who need to convert raw marks into a percentage score, letter grade, and pass or fail status instantly. The calculator offers two distinct modes to suit different needs. The Simple Calculator mode accepts a single total scored marks value and a maximum marks value to produce an immediate overall percentage result with grade and status. The Subject-wise Calculator mode allows individual subjects to be added one by one — each with a subject name, marks obtained, and total marks — to generate both a per-subject percentage and grade breakdown and a cumulative overall percentage across all entered subjects. All results are colour-coded by performance level, with grades assigned across the full A+ to F scale and pass or fail status clearly indicated. Subject entries can be saved locally to the browser between sessions, deleted individually, or reset entirely for a fresh calculation. Whether you are checking exam results, preparing transcripts, or planning academic progress across multiple subjects, this calculator makes the process clear and effortless. Completely free, no registration required.

How Marks Percentage Is Calculated

Marks percentage is calculated using a straightforward formula that expresses obtained marks as a proportion of the total maximum marks.

Marks Percentage Formula: Percentage (%) = (Marks Obtained ÷ Total Marks) × 100

Example — Simple mode with 450 marks out of 500: Percentage = (450 ÷ 500) × 100 = 90%

Subject-wise Overall Percentage: Overall Percentage = (Sum of All Marks Obtained ÷ Sum of All Total Marks) × 100

Example across three subjects:
