When Should You Use the On-Screen Calculator During CAT 2026?
- The calculator is more relevant to numerical questions in DILR and QA than to VARC.
- In DILR, candidates may need to calculate differences, ratios or averages across several data points.
- In QA, the need depends on the calculation involved. A calculator cannot replace the mathematical reasoning required to solve these questions.
- 80% of your calculations should rely on mental math or pen and paper.
- 20% of your calculations might need the on-screen calculator.
| CAT Section | Question Type | Calculator Usage |
|---|---|---|
| VARC | Reading Comprehension | Generally not required |
| VARC | Verbal Ability | Generally not required |
| DILR | Tables and charts | Useful for lengthy calculations |
| DILR | Data comparison | Useful for checking numerical differences |
| QA | Percentage and ratio | Depends on calculation complexity |
| QA | Arithmetic involving large numbers | Useful for verification |
| QA | Algebra and equations | Usually requires conceptual solving rather than calculator use |

Ques. Can I use the calculator during the CAT DILR section?
Ans. Yes, the on-screen calculator is available during the examination. It can help candidates perform lengthy numerical calculations in Data Interpretation and Logical Reasoning questions.
Examples of Calculations Where a Calculator May Help
The deciding factor should be the time required to calculate, not the difficulty of the question alone.
For example, calculating 25% of 800 mentally is straightforward because 25% equals one-fourth. Using the calculator for this operation may add unnecessary steps.
| Calculation | Example | Suggested Method |
|---|---|---|
| Simple percentage | 10% of 450 | Mental calculation |
| Fraction conversion | 25% of 800 | Mental calculation |
| Large multiplication | 347 × 286 | Calculator or written calculation |
| Lengthy division | 1,245 ÷ 35 | Calculator or approximation |
| Numerical verification | Comparing two calculated values | Calculator |
| Repeated calculations | Multiple values from a DI table | Calculator where necessary |

How to Use the CAT On-Screen Calculator Without Losing Time?
The calculator can help with arithmetic, but repeatedly opening it for simple calculations may interrupt the solving process. Candidates should practise using it only when the calculation justifies the additional steps.
Smart Strategies for CAT Calculator Use
| Strategy | How to Apply It | Example |
|---|---|---|
| Estimate before calculating | Identify the approximate answer range | Estimate 19% of 500 before calculating |
| Use mental maths for simple values | Calculate familiar percentages mentally | 50% of 640 = 320 |
| Use the calculator for lengthy operations | Enter multi-digit calculations | 458 × 276 |
| Check the input before pressing equals | Verify numbers and operators | Confirm 458 × 276, not 458 + 276 |
| Avoid repeated calculations | Store or note intermediate values where possible | Use memory functions if available |
| Keep the question visible | Reposition the calculator if it covers data | Useful for table-based DILR questions |
Ques. Does using a calculator save time in CAT?
Ans. It depends on the calculation. A calculator may help with lengthy multiplication or division, while mental calculation may be faster for simple percentages and fractions.
How to Improve Calculation Speed for CAT 2026?
