CAT exam is conducted in a computer-based format and includes an on-screen calculator that appears on the test interface. This tool can be helpful in calculation-heavy sections like Quantitative Ability and Data Interpretation.
While the calculator is basic, knowing how and when to use it can give you a real edge over other candidates. Whether it’s simplifying large number divisions, percentages, or avoiding manual calculation mistakes, using this tool effectively can save valuable time and boost your accuracy.
Features of the CAT Calculator and How It Works
The CAT on-screen calculator is a simple on-screen tool provided within the test interface. It is offered to help candidates with basic arithmetic during the exam. However, it is not a scientific calculator and does not support advanced functions like logarithms, trigonometry, or memory functions.The on-screen calculator in CAT is available throughout the exam and can be opened whenever needed. Its design is clean and easy to use, so even those without a technical or math-heavy background can use it comfortably. While it doesn’t have advanced functions, it’s a handy tool for long or tricky calculations that might take extra time if done manually. Using it wisely can help save time and prevent common errors.
Key Functions Available:
- Basic Arithmetic: Addition (+), Subtraction (–), Multiplication (×), Division (÷)
- Square root (√) function for quick root calculations
- Decimal input and clear/delete functions for ease of editing numbers

When to Use the Calculator in CAT 2025 Exam?
Students should avoid relying too heavily on the on-screen calculator during CAT. It is not intended for every question, especially those that involve basic arithmetic. Using it unnecessarily can slow you down, as the calculator interface requires manual clicking for every input. If a question can be solved mentally or through basic steps, it’s best to do so. Having good calculation speed and accuracy before the exam is essential. Candidates are encouraged to build a strong grip on manual calculations and use the calculator only when required.That’s why knowing exactly when to use it is crucial.
There are circumstances to use the calculator as mentioned below.
- Use the calculator for long and time-consuming calculations, especially those with large numbers or multiple steps.
- It’s useful when answer options are very close, particularly in decimal-based questions where precision is essential.
- In Data Interpretation sets, the calculator helps when you need to add multiple values or calculate averages quickly.
- Use it for questions involving complex ratios, percentages, or multiplications that are difficult to do mentally.
- When a question demands high accuracy, especially with decimal points, the calculator can help avoid mistakes.
- Rely on it when manual solving may lead to errors or slow you down unnecessarily.

Best Ways to Use the CAT On-Screen Calculator Efficiently
The CAT on-screen calculator is provided to help candidates during lengthy or complex calculations, but using it smartly is key. It appears as a clickable tool on the computer screen during the test and does not support keyboard input. To make the most out of it, you must know how to use it without wasting precious minutes.
Step-by-Step Guide:
- Locate the Calculator: A small calculator icon will be visible on the screen throughout the test. Click it to open.
- Manual Input Only: Use your mouse or trackpad to click on the numbers and operation symbols. Keyboard shortcuts are not enabled.
- Basic Operations Only: The calculator supports only basic operations, including addition, subtraction, multiplication, division, and square roots.
Tips to Maximize Efficiency:
- Use Only for Complex Numbers: Avoid using the calculator for basic calculations. They are better done mentally or with rough paper.
- Know When to use: Since every digit or operation must be clicked with the mouse, this can be time-consuming. Use the calculator only when you're confident that manual solving will take longer.
- Prepare Through Practice: Practice using the on-screen calculator while taking mock tests. This helps build familiarity and reduces time wasted searching for digits or functions on test day.
- Don’t toggle repeatedly: keep the calculator open only when necessary. Constant opening and closing can disrupt your rhythm and distract you from your focus.
Mistakes to Avoid While Using the Calculator in CAT
The on-screen calculator in the CAT exam is a helpful tool, but if used carelessly, it can cause more harm than it helps. Here are some frequent mistakes candidates must avoid:
- Misclicking or Input Errors: Using a mouse to enter every digit increases the risk of clicking the wrong number or operator, especially under time pressure. A single misclick can result in an incorrect final answer.
- Wasting Time on Easy Calculations: Relying on the calculator for basic arithmetic slows you down unnecessarily. Candidates should only use it for complex calculations that are time-consuming to solve manually.
- Depending Too Much on the Calculator: Overusing the calculator may lead to ignoring mental math skills, which are often faster. It also increases the chance of mechanical errors if the candidate doesn’t understand the core concept.
- Not Being Comfortable with the Interface: If you haven’t practised using the CAT calculator before the exam, you may end up spending precious seconds just figuring out how it works. Familiarity is key.

Preparation Tips for Mastering the CAT Calculator
To use the CAT on-screen calculator effectively, you must practice it in your preparation:
- Use It in Mock Tests: Practice with the calculator exactly as it appears in the actual CAT interface. This helps you get used to the layout and understand when using it is beneficial.
- Focus on Time-Saving Use Cases: Don’t treat the calculator as a substitute for manual calculations. Instead, prepare yourself to use it only for the specific use cases where it can truly be helpful.
- Simulate Real Exam Conditions: When administering sectional or full-length mock tests, adhere strictly to the exact rules of calculator usage. Avoid pausing or rewinding your thought process. Use it as you would on the actual exam day.
Review after every mock: After completing a mock, go back and redo every question involving calculation, both with and without the calculator. This improves calculation speed and helps you determine if calculator use was the right decision, and helps you decide in future when to use.
