      Why is there a shipping charge for this item?

      Sellers with Flipkart Assured waive off the delivery charge for Orders over Rs 500. For Orders under Rs 500, a nominal delivery charge is added per item.

      Sellers without Flipkart Assured may or may not add a delivery charge to your Order. This is subject to Seller discretion.

      What is the estimated delivery time?

      Sellers generally procure and ship the items within the time specified on the product page. Business days exclude public holidays and Sundays.

      Estimated delivery time depends on the following factors:

      • The Seller offering the product
      • Product's availability with the Seller
      • The destination to which you want the order shipped to and the Seller's location

      Why does the delivery date not correspond to the delivery timeline of X-Y business days?

      It is possible that the Seller or our courier partners observe a holiday between the day you placed your order and the date of delivery, which is based on the timelines shown on the product page. In this case, we add a day to the estimated date. Some courier partners and Sellers do not work on Sundays and this is factored in to the delivery dates.

      What do the different tags like 'In Stock', 'Available' mean?

      'In Stock'

      Products‘In Stock’ are readily available with seller.


      Products listed as ‘In Stock’ are readily available with seller.

      Sometimes, items have to be sourced by Sellers from outside India. These items are mentioned as 'Imported' on the product page and can take at least 10 days or more to be delivered to you.

      'Back In Stock Soon'

      The item is popular and is sold out. You can however 'book' an order for the product and it will be shipped according to the timelines mentioned by the Seller.

      'Out of Print'

      This product is not available because it is no longer published and has been permanently discontinued.

      Why does the estimated delivery time vary for each seller?

      Delivery times are influenced by product availability, geographic location of the Seller, your shipping destination and the courier partner's time-to-deliver to your location.

      Please enter your default pin code on the product page to know more accurate delivery times on the product page itself.

      Seller does not/cannot ship to my area. Why?

      Enter your pincode on the product page to know whether the product can be delivered to your location.

      If you haven't provided your pincode until the checkout stage, the pincode in your last used shipping address will be used to check for serviceability.

      Whether your location can be serviced or not depends on:

      • Whether the Seller actually ships to your location
      • Legal restrictions, if any, in shipping particular products to your location
      • The availability of reliable courier partners in your location

      At times Sellers prefer not to ship to certain locations. This is entirely at their discretion.

    Attention please CA CMA and CS students

    This is the best calculator if you are doing CA or CS or CMA course.. I am a CA Finalist And CMA intermediate student and i can tell you this is the best one for us. The '000' and '00' buttns help a lot plus it has tax,sell,margine etc buttns. It is big enough to calculate faster as you know each and every second is important to us in the exam. This is made for CA,CMA or Cs students or any other courses related to Accountancy or Commerce... Go for it.

    good options in the calculator ... but bigger in size.

    when this product was delivered in my office ... my colleagues said why you have spent 470 bugs only for a simple desktop calculator which is not even a Scientific cal . They said we can get a good desktop calculator for 300 bugs in the market .
    when i opened the delivered parcel i heard no voice from them .
    There is no comparison with other desktop cal available in the market.It is got good options which will help really a lot in the Accounts exam.I have presented this calculator to my wife...
