Can You Use a Calculator on the GMAT?

Yes, but only on the Data Insights section. The GMAT provides an on-screen calculator for Data Insights questions.

You cannot use a calculator on the Quantitative Reasoning or Verbal Reasoning sections, and personal calculators are not permitted anywhere on the exam.

Why No Calculator on Quant?

The Quantitative Reasoning section is designed to test your ability to reason with mathematics, not perform lengthy calculations. Most GMAT quant questions are written so that heavy computation is unnecessary. The path to the correct answer usually rewards efficient problem-solving, smart setup, and careful analysis rather than grinding through arithmetic.

Viewed through that lens, it makes sense that the Quantitative Reasoning section doesn’t provide a calculator. The skill being tested isn’t calculation speed — it’s your ability to identify an efficient approach and apply it correctly.

What This Means for Your Prep

Practice Quant the way it will be tested: using mental math, efficient setups, and calculations on paper as needed. The more familiar these habits become during your preparation, the more naturally they’ll come to you on test day.

For Data Insights, we recommend getting comfortable with the on-screen calculator during your prep. Knowing when and how to use it efficiently can save valuable time during the exam.
