![Three calculators priced in this read of Amazon's shelf - the Rs. 349 Amazon Basics AB-82MS, the Rs. 593 Casio FX-82MS and the Rs. 1,559 Casio FX-991CW Classwiz - shown as they appear in their own listing photographs]()
Three cards on Amazon's scientific calculator shelf sell a machine printed AB-82MS. One is Rs. 349 and carries 438 ratings. The other two are Rs. 529 and carry 15 and 12. Same model number, same stated 240 functions, Rs. 180 apart, with twenty-nine times the evidence sitting on the cheapest tile.
The rest of the shelf is the flattest we have read all morning. Its median discount badge is 9.5%, because Casio holds 9 of the 16 listings and never shows more than 12% off - while every deep badge on the page belongs to the marketplace's own brand or to Orpat. Below: who discounts what, the three listings with no MRP at all, and why half these results are not scientific calculators.
📅 Update log:
1 October 2026 — first published. The shelf was read on the morning of 1 October 2026 from amazon.in's own search results for 'scientific calculator', logged out, in India, with nothing purchased; 16 listings were returned. The split between scientific and basic calculators follows what each listing's own title states - a stated function count, a two-line display or the word 'scientific'. The comparison shelves named here were read the same morning from the same source by the same method. Every price, stated MRP, badge, star average and rating count quoted was read on that date.
The same calculator at Rs. 349 and Rs. 529
We read Amazon's whole 'scientific calculator' shelf on the morning of 1 October 2026, logged out, in India, with nothing purchased. Sixteen listings came back, and three of them sell a calculator printed AB-82MS - Amazon's own-brand scientific model. One is Rs. 349. The other two are Rs. 529.
The cheap one is also the best evidenced: 438 ratings at 4.0, against 15 and 12 on the two dearer tiles. Those are 29 and 36 times the feedback, for Rs. 180 less. The three publish different rating counts, so they are three separate listings rather than one product shown three times - but the printed model number and the stated 240 functions are the same on all three.
The badges, as usual, point the wrong way round only by accident. The Rs. 349 tile states an MRP of Rs. 1,199 and shows 71% off; the Rs. 529 tiles state Rs. 1,118 and show 53%. Here the deepest badge does happen to sit on the cheapest tile - but that is because the MRPs differ by Rs. 81, not because anyone measured anything. If you want this calculator, search the model number rather than the category and compare what comes back.
| Three tiles, one printed model number, 1 Oct 2026 | Price | Stated MRP | Badge | Ratings |
|---|
| Amazon Basics AB-82MS | Rs. 349 | Rs. 1,199 | 71% | 438 at 4.0 |
| Amazon Basics AB-82MS | Rs. 529 | Rs. 1,118 | 53% | 15 at 4.3 |
| Amazon Basics AB-82MS | Rs. 529 | Rs. 1,118 | 53% | 12 at 4.1 |
The one-line version: on this shelf the same own-brand scientific calculator sells at Rs. 349 and Rs. 529, and the Rs. 349 tile carries twenty-nine times the ratings. Search the model number, not the category.
Casio discounts four per cent. The own brand discounts seventy-one.
This is the flattest shelf we have read all morning. Its median discount badge is 9.5%, against 70% on Amazon's fairy light shelf, 65% on artificial flowers and 52% on doormats - all read the same day by the same method.
The reason is that one brand owns the shelf and states credible list prices. Casio holds 9 of the 16 listings, and every badge it shows is 12% or smaller - 4%, 5%, 6%, 6%, 8% and 12% - while three more Casio tiles state no maximum retail price at all and therefore show no badge. A Rs. 593 FX-82MS against a stated Rs. 625 is a 1.05x multiple. A Rs. 1,559 Classwiz against Rs. 1,695 is 1.09x.
Every deep discount on this shelf belongs to someone else. Amazon's own brand takes 71%, 53%, 53% and 46%; Orpat takes 44%. That is the familiar shape - the challenger states the higher list price so it can print the bigger percentage - and it is unusually legible here because the market leader does not play. An MRP is a figure the listing displays and we have not verified that any calculator was ever sold at one; no wrongdoing by Amazon or any brand is alleged.
| Who discounts what, read 1 Oct 2026 | Listings | Badge range | Largest rating count |
|---|
| Casio | 9 of 16 | 0% to 12% | 15,026 |
| Amazon Basics | 4 of 16 | 46% to 71% | 1,341 |
| Deli | 2 of 16 | 11% and 16% | 1,619 |
| Orpat | 1 of 16 | 44% | 12,738 |
Half the results are not scientific calculators
Only 8 of the 16 results actually are scientific calculators. The other eight are basic pocket and desktop machines: a Casio HL-820LV with a flip cover at Rs. 151, an HL-100LB at Rs. 184, an SX-300-W at Rs. 225, an Orpat OT-512GT at Rs. 220, a Casio MJ-12Sb desktop at Rs. 385, an MJ-12D financial desktop at Rs. 440 and an Amazon Basics 12-digit at Rs. 269.
They are not padding, either - they are the popular half. The two most-rated listings on the whole shelf are basic calculators: the Casio MJ-12D with 15,026 ratings at 4.5 and the Orpat OT-512GT with 12,738 at 4.0. The most-rated scientific listing is the Casio FX-82MS with 14,529 at 4.4, which sits between them.
It matters because the two kinds of machine are not substitutes. A basic calculator adds, subtracts and takes a percentage; it will not do sin, cos, log or a standard deviation. If you are buying for a school or college maths syllabus, look for a stated function count - 240 on the FX-82MS, the Deli WD82DMS and the AB-82MS, 562 on the Deli ED562UR - and check your examination board's own rules about which models are allowed, which we have not done for any machine on this page.

Three listings give you a price and nothing else
Three of the 16 state no maximum retail price whatsoever, so they display no badge - a Casio MJ-12Sb desktop at Rs. 385, an MJ-12D at Rs. 440 and an Fx-350Ms scientific at Rs. 585. All three are Casio, and two of them are among the three most-rated listings on the shelf.
That is the opposite of a problem. The MJ-12D at Rs. 440 carries 15,026 ratings at 4.5 - the highest average and the largest count on the shelf - and it will never appear in a discount filter, because there is nothing to compute a discount from. The same is true of the Fx-350Ms at Rs. 585 with 1,557 ratings at 4.4.
Across this whole shelf the pattern is consistent: the badge and the evidence run in opposite directions. The four deepest badges carry 438, 15, 12 and 1,341 ratings. The six listings with more than 2,000 ratings carry badges of 0%, 0%, 4%, 5%, 6% and 44%. On a shelf like this, sorting by discount is close to sorting by how little anyone has bought.
Before you buy: decide whether you need a scientific machine or a basic one, because half these results are the other kind. Then search the model number - FX-82MS, AB-82MS, OT-512GT - rather than the category, which is how you find the Rs. 349 tile sitting behind two Rs. 529 ones.
Frequently Asked Questions
What does a scientific calculator cost on Amazon in October 2026?
In this read of 16 listings, the whole shelf ran Rs. 151 to Rs. 1,559 with a median of Rs. 392 - but only 8 of the 16 are actually scientific calculators. Those eight ran Rs. 349 to Rs. 1,559: Amazon's own AB-82MS at Rs. 349 and Rs. 529, a Deli WD82DMS at Rs. 399, Casio's Fx-350Ms at Rs. 585 and FX-82MS at Rs. 593, a Deli ED562UR at Rs. 1,211 and Casio's FX-991CW Classwiz at Rs. 1,559. These figures describe the 16 listings returned on 1 October 2026, not Amazon's full catalogue.
Why is the same Amazon Basics calculator two different prices?
Because it is listed three times. The AB-82MS appeared at Rs. 349 and twice at Rs. 529 in this read, with the same printed model number and the same stated 240 functions. The three publish different rating counts - 438, 15 and 12 - so they are separate listings rather than one product shown three times. The practical effect is that opening the first card you see can cost Rs. 180, and the cheapest of the three carries twenty-nine times the ratings of either other. Multiple listings of one product are ordinary on marketplaces and no wrongdoing is implied.
Which calculator has the best reviews on Amazon?
A Casio MJ-12D desktop financial calculator at Rs. 440, with 15,026 ratings at 4.5 - the largest count and the highest average on the shelf. It is a basic calculator rather than a scientific one. Among scientific models, the Casio FX-82MS at Rs. 593 leads with 14,529 ratings at 4.4. Both state very small discounts or none at all - the MJ-12D publishes no MRP, and the FX-82MS shows 5% off a stated Rs. 625 - so neither surfaces in a discount sort. We did not buy or use any of them.
Why do Casio calculators show such small discounts on Amazon?
Because their stated maximum retail prices sit close to their selling prices. Casio holds 9 of the 16 listings in this read and every badge it shows is 12% or smaller - 4%, 5%, 6%, 6%, 8% and 12% - with three more stating no MRP at all. A Rs. 593 FX-82MS against a stated Rs. 625 is a 1.05x multiple. By contrast, the deepest badges on the shelf - 71%, 53%, 53%, 46% and 44% - belong to Amazon's own brand and to Orpat. The shelf's median badge is 9.5%, the flattest of five Amazon shelves we read the same morning.
Is a basic calculator enough for school maths?
This page cannot answer that for your syllabus, and it is the reason the shelf is worth reading carefully. Eight of these 16 results are basic pocket or desktop calculators that will not compute sin, cos, log or a standard deviation, and two of them are the most-rated listings on the page. Scientific models here state a function count - 240 on the FX-82MS, Deli WD82DMS and AB-82MS, 562 on the Deli ED562UR. Function counts and 'non-programmable' claims are the listings' own printed text, and we have not checked any model against any examination board's permitted list - check that yourself before buying for an exam.
Prices & codes last verified: October 1, 2026
Zoutons may earn a commission when you buy through links on this page. Every selling price, stated MRP, discount badge, star average and rating count here was read on 1 October 2026 from amazon.in's own search results for 'scientific calculator', logged out, in India, with nothing purchased; 16 listings were returned. The comparison shelves named on this page were read the same morning from the same source by the same method. Every count, median, range and multiple on this page describes those listings on that date rather than Amazon's full catalogue, and a calculator sold there that did not appear in these results does not appear here; search results are ranked, partly personalised and change continuously, so a different reader will not see the same set. Listings are described as selling the same model where they print the same model number in their own titles; that match is made on the printed title alone, we have handled none of these machines, and the three AB-82MS listings publish different rating counts and are treated as three separate listings rather than as one product shown three times. The split between scientific and basic calculators follows each listing's own stated description and function count. Listing one product more than once is ordinary marketplace practice and nothing here is an allegation of mispricing, misleading advertising or any breach of the Legal Metrology Act, the Consumer Protection Act or any other law, rule or platform policy by Amazon Seller Services Private Limited or by Casio, Amazon Basics, Deli, Orpat or any other brand or seller named or unnamed, and no wrongdoing is alleged or implied. An MRP is the figure the listing displays and we have not verified that any product here was ever sold at it, so every percentage and multiple on this page is arithmetic over two numbers the seller chose rather than a measured saving; the observation that one brand's badges are small and another's are large is a description of published figures on one shelf on one date and is not a comment on any brand's pricing practices. Rating counts and star averages are reproduced exactly as published, including very small counts, and a listing with no published rating is treated as unrated rather than as poor. Function counts, 'non-programmable', display lines, memory steps, solar and battery claims, warranty periods and build descriptions are the listings' own printed text, reproduced as printed and not verified or tested by us - nothing here is a statement about accuracy, durability, battery life or fitness for any purpose. We have NOT checked any model on this page against the permitted-calculator rules of CBSE, ICSE, any state board, any university or any professional examination, those rules change and differ between examinations, and anyone buying a calculator for an examination should check the relevant board's own current list rather than relying on anything written here. We did not buy, unbox or use any item on this page. Product photographs are the listings' own images as published on amazon.in and may be styled or retouched. Prices change without notice and can differ at checkout after coupons, bank offers or delivery charges; the price shown at your checkout prevails over anything here.
