Scientific Calculators Allowed in Indian Competitive Exams
Most major Indian competitive exams ban calculators entirely. A handful — GATE and a few CA professional papers — allow specific models. Here is the up-to-date rule sheet for 2026.
Exams that ban calculators completely
JEE Main, JEE Advanced, NEET (UG and PG), CAT, XAT, AIIMS undergraduate, AFMC, CLAT, UPSC Civil Services Prelims, all SSC exams, CDS, NDA, RBI Grade B, and most state PSC exams. In these, candidates use the on-screen four-function calculator built into the test interface (CBT exams) or do all calculation by hand (paper-based exams). Bringing a physical calculator into the centre risks disqualification.
Exams that allow virtual calculators
JEE Main (CBT mode) provides a basic on-screen four-function calculator. GATE provides a virtual scientific calculator built into the exam software — non-programmable, with trig, log, exp, and statistics functions. UGC NET provides a virtual scientific calculator. The virtual tools are limited compared to physical scientific calculators but cover the typical exam need.
Exams that allow physical calculators (with restrictions)
CA Final, CA Intermediate, and CA Foundation (Institute of Chartered Accountants of India) allow non-programmable, non-scientific calculators with up to six digits. ICSI exams (Company Secretary) allow battery-operated, non-scientific, non-printing calculators. CFA exams in India allow specific approved models (Texas Instruments BA II Plus, HP 12C). Always check the latest notification — rules update yearly.
What 'non-programmable' means
A non-programmable calculator cannot store user-written programs or formulas. Standard scientific calculators (Casio fx-991 series, TI-30X) are non-programmable by this definition — they have built-in functions but no user code storage. Programmable calculators (Casio fx-9750, TI-83/84/89) have user-accessible BASIC or similar languages. Most exam restrictions ban the latter category.
What 'non-scientific' means
A non-scientific calculator has only the four basic operations (+ − × ÷), percent, and possibly memory. No trig, log, or roots. Examples: cheap office-style calculators with a 10-digit display. CA and ICSI exams require this lower tier — even a basic scientific would be too capable.
Practical advice for exam day
Read the official exam-day instructions issued by the conducting body — they appear in the admit card and on the official website. Bring only what the rules explicitly allow. If unsure, leave the calculator behind — exam centres typically do not provide replacements, and the rules are strict. For exams that provide a virtual calculator, practise with an equivalent online tool in the weeks leading up to the test.
Frequently asked questions
Is a calculator allowed in JEE Main 2026?
No physical calculator. JEE Main 2026 is computer-based with an on-screen four-function calculator built into the interface. Physical calculators, mobile phones, smart watches, and any electronic device are banned from the exam hall.
Is a calculator allowed in NEET 2026?
No. NEET 2026 is a pen-and-paper OMR exam. No physical or virtual calculator. All numerical work — physics formulas, chemistry stoichiometry, biology genetics — must be done by hand. Log tables are also banned.
Can I use a calculator in GATE?
GATE provides a virtual scientific calculator inside the exam software. Physical calculators are not allowed. The virtual calculator covers trig, log, exp, scientific notation, and statistics — enough for every GATE question type. Practise using an equivalent online calculator before the exam.
Which calculators are allowed in CA exams?
ICAI permits non-programmable, non-scientific battery-operated calculators with up to six digits. No trig, no logs, no scientific functions. The rule is set so candidates do all complex computation manually. Bring a calculator that matches this spec exactly — overspecced models risk disqualification.
Are programmable calculators allowed anywhere?
Almost nowhere in Indian competitive exams. The few exceptions are international exams conducted in India under their own rules — CFA (Texas Instruments BA II Plus is allowed), FRM (same), some IB exams. For Indian-administered exams, assume programmable means banned unless explicitly permitted in writing.
