Percentage Marks Calculator
Percentage = (Marks obtained / Total marks) x 100. Scored 342 out of 500: 342/500 x 100 = 68.4%. For 10th CBSE: add all subject marks and divide by total maximum marks. For boards where each subject is out of 100: sum of 5 subjects / 500 x 100 gives your aggregate percentage.
25% of 200 = 50

Frequently asked questions
How do I calculate percentage increase?
Percentage increase = ((New value − Old value) / Old value) × 100. Example: salary goes from ₹50,000 to ₹60,000. Increase = ((60,000 − 50,000) / 50,000) × 100 = 20%. A negative result indicates a decrease.
How do I calculate percentage of a total?
Divide the part by the total and multiply by 100. Example: if you scored 85 out of 100, the percentage is (85/100) × 100 = 85%. For 250 out of 400, it's (250/400) × 100 = 62.5%.
What is 30% off a ₹1,500 item?
30% of ₹1,500 is (30/100) × 1,500 = ₹450. The discounted price is ₹1,500 − ₹450 = ₹1,050. Equivalent shortcut: multiply the original price by 0.7 (i.e., 70%).

CA: no minimum, but top firms recruit 60%+ in graduation. MBA top colleges: 60-65%+ graduation marks typically required. Medical colleges: 50%+ in PCB (Physics, Chemistry, Biology) at 12th level.
How do I calculate grade percentage in JEE Advanced?
JEE Advanced marks are absolute, not percentage-based. Your JEE Advanced rank depends on the cut-off for each branch and college. However, if converting raw marks: JEE Advanced maximum marks are typically 360. If you scored 216/360: 216/360 x 100 = 60%. But college admission goes by rank, not percentage - a 60% score in an easy year ranks differently than 60% in a tough year.
