Best Scientific Calculators Under ₹2000 in India (2026)
Under ₹2,000 is the sweet spot for student scientific calculators in India — enough budget to get a reliable model with the full function set, without paying for graphing or CAS features most students never use. Here are the strongest options in this range for 2026.
Casio fx-991ES Plus 2nd Edition (₹1,150–₹1,400)
The single most popular pick. 417 functions including matrix, complex number, and base-N modes. Natural V.P.A.M. fraction display. Solar + battery hybrid. 3-year warranty through Casio India. Used by millions of Indian students for JEE, NEET, GATE, and university coursework. The best value at this price by a clear margin. Build quality is solid — buttons last 5+ years of daily use.
Casio fx-82MS (₹450–₹650)
Entry-level Casio with the core scientific function set — trig, log, exp, root, factorial. No natural-display fractions; no matrix mode. Two-line display. Battery-only (no solar). Best for Class 9–11 students whose syllabus does not yet need the ES Plus's extra modes. Build quality is decent; the buttons feel a touch cheaper than the ES Plus.
Casio fx-100MS (₹800–₹1,000)
Sits between the 82MS and 991ES Plus. Larger function set than 82MS but no natural-display fractions. Solar + battery hybrid. Useful for budget-conscious students who want better build quality and battery life without paying for the natural display. Reasonable choice if the 991ES Plus is out of stock.
Texas Instruments TI-30X Pro MathPrint (₹1,800–₹2,000)
The international alternative to the Casio 991 series. MathPrint display shows expressions in textbook form. Slightly different button layout — sin, cos, tan are arranged in a row rather than a column. 380 functions. Build quality matches the Casio. The choice if you prefer the TI layout or are continuing with TI calculators from earlier school years.
Sharp EL-W535TG-WH (around ₹1,600)
Sharp's WriteView display rivals Casio's natural V.P.A.M. for fraction and surd readability. 422 functions. Less common in Indian retail than Casio or TI — sometimes hard to find in stock outside major cities. Build quality is good. Choose if you specifically want a Sharp ecosystem or find it discounted below Casio's price.
Buying advice
Buy from Amazon (sold by Casio India), Flipkart (authorised seller), Reliance Digital, or Croma — all stock manufacturer warranty units. Avoid local market 'discounted' calculators — these are often grey-market imports with no warranty in India. Check the box for the authorised Indian distributor seal. Battery life: solar + battery hybrids beat battery-only by years of usable life. For ₹100–₹200 more, the solar option is worth it.
Frequently asked questions
What's the best scientific calculator under ₹1500?
Casio fx-991ES Plus 2nd Edition. At ₹1,150–₹1,400, it offers the full 417-function set including matrix, complex number, and natural-display fractions. Solar + battery hybrid. 3-year warranty. The clear best value in the under-₹1,500 segment for 2026.
Should I buy a Casio fx-82MS for class 10?
Yes, if your budget is tight. The fx-82MS at ₹450–₹650 covers everything in the Class 10 maths and science syllabus. It lacks natural-display fractions and matrix mode, which become useful in Class 11–12. If you can stretch the budget, the fx-991ES Plus is a longer-term investment.
Is the Texas Instruments TI-30X better than the Casio fx-991ES Plus?
Different ecosystems, similar capability. The TI-30X has MathPrint display; the Casio has natural V.P.A.M. — both render fractions and surds clearly. Casio dominates the Indian market by availability and price; TI is more common abroad. For Indian students, Casio is easier to buy and replace. Either model handles every Indian exam syllabus equally well.
Where should I buy a scientific calculator in India?
Authorised online sellers: Amazon (Casio India), Flipkart (authorised badge), Reliance Digital online, Croma online. Authorised physical stores: Reliance Digital, Croma, Vijay Sales. Avoid local market 'cheap' deals — these are usually grey-market and lack Indian warranty. The ₹100–₹200 savings are not worth losing the 3-year manufacturer warranty.
How long does a Casio scientific calculator last?
5–7 years of daily student use is typical. Solar + battery hybrids extend usable life by reducing battery drain — the LR44 backup battery typically needs replacing once every 3–4 years. Buttons start losing crisp click after about 5 years of heavy use. The display itself rarely fails.
