How to Choose a Calculator for General Purposes in India

You must consider the following factors when you’re looking for a calculator to suit your needs perfectly.

Consider Your Use

Consider Your Use

If you usually need basic arithmetic help, then a low-end 8 digit calculator without too many features should be enough. These types can only do the four basic operations, as well as calculate square roots and percentages.

On the other hand, if your calculations are more complex, and need tax functions, check and correct, and a lot of memory, there are calculators which can do that as well. There are also financial and scientific types with exponents, permutations and combinations, and logarithm functions.

The Most Suitable Size for You

Right Size for Your Need

Calculators are available in a variety of sizes; some can even be the size of a B5 notebook. Smaller calculators are more portable, but they can be hard to use as their keys are small too. Larger ones can have better displays, but they are more cumbersome to carry around. Usually, the smaller a calculator is, the more basic it is.

Look at the Key Size and Shape

Look at the Key Size and Shape

Design of the keys is something you need to consider if you want to choose a user-friendly calculator. Those with rectangular keys are usually better for accuracy and comfort because the keys fit the fingertips. Try not to choose calculators with keys that are fully hidden by your index finger.

More Digits on the Display for Large Numbers and Decimals

More Digits on the Display for More Usability

For students and accountants, at least ten digits should be visible on the display of a calculator. It would not only enable them to work with large numbers but also give more accurate decimal values. Although since money related calculations often contain large numbers, the ideal choice would be a 12-digit calculator.

Avoid the Lightweight Ones and Make Sure there are Rubber Grips

 Avoid the Lightweight Ones and Make Sure there are Rubber Grips

Your calculator should be able to withstand the force used on keys during fast calculations. It is better to invest in a sturdy calculator than a potentially fragile one. A lot of calculators also come with rubber grips at the back to prevent them from slipping or falling.

Key Rollover Function

Key Rollover Function

Nowadays, most calculators, aside from low-end models, come with the key rollover feature. This feature helps the device recognise the correct order when multiple keys are pressed in quick succession. This is an important function, because, without this, the accuracy of the calculations would be compromised. If you’re someone who works really fast, then we strongly recommend you to check for this function.

Tilting or Folding Screen

Tilting or Folding Screen

Another useful feature is a foldable or tilt screen as it improves visibility. Since LCD screens are not very clear when looked at from certain angles, it helps to be able to tilt them, so they align with your line of vision.

Other Useful Functions

Other Useful Functions

There are some other useful features which you may want in your calculator too. A GT key, which is the Grand Total key, would be useful for calculating the sum of all previous results. It prevents you from wasting time on manually adding all the results at the end. You may also be interested in the Memory function to store a certain number of previous calculations for reference. These two features would be particularly useful for those who deal with accounts and statistics.

Top 10 Best Calculators to Buy Online in India

We shall now give you a list of top 10 best calculators you can buy online in India. We’ve only mentioned calculators which can display 12-digits at the least, and are solar plus battery powered unless described otherwise.

Basic Calculator with a Large Screen

This is a calculator for those who want a 12-digit display and only need the basic functions. The large display makes it easier for the user to view the numbers. It is also very conveniently sized as it can fit your hand and you can carry it around. Another plus point is its dual power battery, which allows it to run on normal batteries as well as solar power.

On the downside though, it may seem quite expensive for a simple calculator which lacks any complex functions. Since it does not have the tax functions, if you’re someone who needs to calculate taxes quite often, this might not be the right choice for you. It may also seem too small for those who are used to working with bigger calculators.

Inexpensive Option for Basic Operations

If you’re not into complex features and want an inexpensive option for daily needs, this is the one for you! It has a large display, big keys, check buttons, and an auto replay button. All of these would come in handy when you’re managing your daily expenses or for simple calculations. It also has an angled screen so you can view it from various angles.

Although, it does lack some of the features necessary for finance related calculations, such as the Grand Total button. The keys are also on the softer side which makes it hard to press them and may slow down your work. If you do not like to compromise the speed of your work, then this might not be the best option for you.

Ultra-lightweight Foldable Calculator with Large Display

For those looking for an easy to carry, lightweight calculator, this would be the right choice. It is quite small and weighs only nine grams, but it performs all basic mathematical operations. If you’re not too worried about the price and only concerned with buying the most portable option, then this is the one for you.

However, there are a few negatives to this calculator, the biggest one being the price. It is the most expensive product on the list and may not seem like a justifiable investment for a basic calculator. Furthermore, since it doesn’t have a large display, it can only show 8 digits, which makes it hard to deal with calculations involving large numbers.

Simple Calculations Made Easier with Bright Colours

All those who only do simple calculations and are sick of using dull calculators would love this product. Aside from the unique colour scheme, it has a clear display, easy-to-press keys, and is quite small in size, which makes it a great choice for those looking for portable options too. Additionally, while most basic calculators only have 120 steps check available, this one has a 300 steps check.

Since it is a simple calculator, it doesn’t have the tax function and GT keys, so it’s not useful for those working with finances. It may also seem quite expensive for the functions it performs, so if you’re looking for a more budget-friendly option, then there are some other basic calculators on this list which may appeal to you.

It is the perfect choice for those looking for a product that can fit into their back pocket. It also comes with a three-year warranty so in case you damage it, you can always get it repaired.

However, due to its size, it only has an eight digits display, and it isn’t dual-powered either, so it cannot run on solar power. It may also seem harder to use for those used to plastic keys as this has soft, rubber keys. Lastly, if you require complex calculations, this will not suffice, and you should consider one of the other calculators we’ve mentioned.

On the downside though, it does not have most of the features needed for financial calculations such as the Grand Total key and the tax rate keys.

However, due to its size, it would not be appropriate for those looking for portable options. This may also not last as long as it isn’t dual powered and cannot run on solar power.
