The Usual Price Range in Bangladesh
Let’s begin with the basics. On average, the Casio FX-991ES Plus is priced between BDT 1,400 to BDT 1,800 in Bangladesh. You might occasionally see it for less or more depending on the seller, location, or any promotions going on.
Some premium stores and official retailers may charge on the higher end, but that usually comes with added perks like product warranty, genuine packaging, and after-sale support. On the other hand, local markets or unauthorized vendors might offer lower prices, but you’ll need to be extra cautious about authenticity.
Now let’s explore where you can actually buy one.
1. Local Stationery Markets – Best for Bargain Hunters
If you’re someone who loves to see and test what you're buying, local stationery hubs are a great place to start. In Dhaka, areas like Nilkhet, New Market, and Boi Bazar are go-to spots for students. You'll find multiple vendors selling calculators at competitive prices, especially if you know how to negotiate a little.
The benefit of buying from these markets is the price flexibility. You can compare rates across several shops and sometimes even shave off a few extra taka just by asking.
However, do check for the official Casio hologram on the box and test the calculator before purchasing. Some shops may sell imported or duplicate versions at lower rates, which can look convincing but lack the durability of the real thing.
2. Online Marketplaces – Convenience at Your Fingertips
Online shopping is booming in Bangladesh, and calculators are no exception. Websites like Daraz, Pickaboo, and other local e-commerce platforms often stock the Casio FX-991ES Plus. The key advantage here is convenience—you can order from anywhere, compare prices instantly, and even check user reviews before buying.
Look out for sales, flash deals, or special discount codes. During events like Eid or back-to-school campaigns, these platforms frequently offer attractive prices. You may even snag a deal for under BDT 1,500 with free delivery.
Just make sure to buy from a trusted seller or one with the “Mall” or “Official Store” tag where available. These indicate verified vendors and reduce the risk of getting a fake product.
3. Branded Electronics Shops – For Peace of Mind
If you prefer buying from an official outlet with guaranteed authenticity, visit branded electronics or gadget shops in your city. Places like Multiplan Center (Dhaka) or large superstores in Chattogram, Sylhet, or Rajshahi often stock Casio calculators.
While the price may be slightly higher—usually closer to BDT 1,800—you get the confidence of buying a genuine product. These stores usually provide a purchase receipt, return policy, and in some cases, limited warranty coverage.
For students who want to avoid any risk or simply don’t want to deal with bargaining or product checking, this is a reliable option.
4. School and Coaching Center Vendors – Unexpected Deals
Believe it or not, many coaching centers and schools also sell scientific calculators directly to students. Some even place bulk orders and pass on the cost savings to their students.
If you’re enrolled in a coaching program for university admission or a board exam prep course, ask if they offer calculators as part of their materials or through affiliated shops. In many cases, the prices are lower than retail stores since these deals are based on bulk purchases.
The added bonus? These calculators are almost always authentic, and teachers often guide students on how to use them right after purchase.
5. Secondhand Market – A Risky but Cheap Option
If your budget is extremely tight, you might come across used FX-991ES Plus calculators in Facebook groups, local forums, or even among friends. The price for a secondhand unit can range from BDT 700 to BDT 1,200, depending on condition.
But this comes with a warning: check thoroughly before buying. Look for dead pixels, unresponsive buttons, or worn-out batteries. If it’s still in good working condition, it could be a temporary solution—just know that you may need to replace it down the line.
Tips for Spotting the Real Deal
Because of the calculator’s popularity, there are plenty of fake or knock-off versions circulating in the market. Here’s how to protect yourself:
- Check for a hologram seal on the box that says “Casio Original.”
- Look at the screen quality. Fake calculators often have dim displays and unclear fonts.
- Test the buttons. Originals have soft but firm tactile feedback, while fakes may feel flimsy.
- Check the model number at the back and compare it with Casio’s official listing online.
- Avoid suspiciously low prices. If someone’s selling it for way below BDT 1,000 brand new, it’s probably too good to be true.
Final Thoughts: Where’s the Best Deal?
The answer depends on what you prioritize. If price is your main concern and you're confident in checking for authenticity, local stationery markets like Nilkhet or New Market in Dhaka offer some of the best deals. If convenience and safety matter more, online platforms with verified sellers or branded stores are better options—even if they cost a bit more.
No matter where you buy it from, the Casio FX-991ES Plus continues to offer outstanding value. With a wide range of functions, excellent durability, and proven performance in exams, it remains a smart investment for students in Bangladesh.
So before you make your purchase, compare your options, know what to look for, and choose the seller that matches your comfort level. A few extra minutes of research can save you money—and maybe even a headache later.
