Convert marks to percentage or percentage to marks — both directions, instantly.
The Percentage Calculator handles both essential student conversions in one place. Switch between "Marks → Percentage" to find what your raw score equals as a percent, and "Percentage → Marks" to figure out the actual marks behind a target percentage. Calculations update live as you type — no submit button, no waiting.
It's an everyday tool for students, teachers, and parents: comparing scores across exams with different totals, decoding report cards, translating "you need 75%" into a real number, or quickly grading a stack of papers. Works for school exams, college midterms, university finals, and competitive tests like SAT, GRE, or board exams.

Divide the marks obtained by the total marks, then multiply by 100. For example, 425 out of 500 = (425 / 500) × 100 = 85%.
Multiply the percentage by the total marks, then divide by 100. For example, 80% of 750 total = (80 × 750) / 100 = 600 marks.
This tool handles raw percentage conversion. For GPA on the 4.0 scale, use our dedicated GPA Predictor — it converts grades and credits into a precise weighted GPA.
Results are shown to two decimal places for accuracy. The underlying calculation uses full precision, so you can trust the value for grading or planning.
