Marks Percentage Calculator — Exam & Board Results
The marks percentage calculator is designed for students appearing in CBSE, ICSE, SSLC, IGNOU, state board, or university semester exams.

CGPA to Percentage Calculator — Convert CGPA & SGPA
The CGPA to percentage calculator supports all three major grading scales used by Indian universities: the standard 10-point scale (CGPA × 9.5, used by most autonomous colleges), a 7-point scale (CGPA × 13.57), and the 4-point GPA scale common in international programs (GPA × 25). VTU, Mumbai University, and Anna University typically follow their own official multipliers — the tool displays the conversion formula for each scale choice, keeping everything transparent and verifiable.
Students frequently need to convert their SGPA or CGPA while applying for jobs, postgraduate programs, or visa applications. The formula is university-specific: always verify with your institution's official guidelines, as some universities like Anna University use CGPA × 10 instead of × 9.5.
Salary Hike & Discount Percentage Calculator
The Hike tab serves two popular sub-calculations. The hike percentage calculator takes your old and new salary as inputs and immediately outputs the salary hike percentage with the underlying formula. This is useful during appraisals, job changes, and offer comparisons. If your salary increased from ₹40,000 to ₹52,000, the hike calculator shows you instantly that this is a 30% raise, not just a number you have to mentally estimate.
The Discount sub-tab works as a discount percentage calculator: enter the original price and the discount percentage to see both the final payable amount and exactly how much you are saving. This is ideal for shopping decisions, billing, and GST calculations as well.
Win Percentage & Average Percentage Calculator
The win percentage calculator is built for sports analysts, gamers, and coaches. Enter total wins and total games played and the tool computes the precise winning percentage alongside the win-loss breakdown. Win percentage is calculated using: (Wins ÷ Total Games) × 100. If a team won 24 out of 30 games, their win rate is 80%.
The Average Percentage mode computes the average percentage across a dynamic set of values — add as many subjects, tests, or scores as needed using the "+ Add" button. This is ideal for a semester result, multiple test scores, or any situation where you need one unified percentage figure from several individual values.
How to Calculate Percentage in Calculator (Step-by-Step)
The formula for percentage is: Percentage = (Part ÷ Whole) × 100. On a basic calculator or phone:
- Type the part value (e.g., 45).
- Press ÷ (divide).
- Type the whole value (e.g., 60).
- Press × (multiply), then type 100.
- Press = — you get 75%.
On an iPhone or Android calculator, many apps have a dedicated % button. To find 20% of 500: type 500, tap ×, type 20, tap %. The phone computes it directly as 100. For how to calculate percentage in mobile calculator: use the shortcut by tapping the % key instead of typing ÷ 100. Calculator se percentage kaise nikale?

Percentage Formula & Real-Life Examples
There are three core percentage formulas:
- Find a percentage of a number: Result = (X ÷ 100) × Y → e.g., 15% of 200 = 30
- Find what percentage X is of Y: Result = (X ÷ Y) × 100 → e.g., 45 out of 60 = 75%
- Percentage increase/decrease: Result = ((New − Old) ÷ |Old|) × 100 → e.g., 80 to 100 = +25%
These formulas cover the vast majority of real-life use cases: restaurant tips, shopping discounts, salary hike analysis, bank interest approximations, academic grade calculations, and sports statistics.
Attendance Percentage Calculator
To calculate your attendance percentage, use the Basic → "X is ?% of Y" mode. Enter the number of classes attended as X, and total classes held as Y. For example, attending 42 out of 60 classes = (42 ÷ 60) × 100 = 70% attendance. Most universities require a minimum of 75% attendance to be eligible for final exams — use this tool to track where you stand at any point in the semester and how many classes you can still miss while staying above the threshold.
