Financial Calculators Buyer’s Guide

Now that you know 13 of the best financial calculators of 2021, it’s time to finalize on a unit that suits you best. But based on what criteria are you selecting a particular unit? Well! This can be slightly tricky if you don’t have a clear picture of the factors that you need to look for. 

So, for a better understanding, we have narrowed down a few parameters that you should consider while selecting the best financial calculator. 

So, let’s check them out!

  1. What will you be using the calculator for?

If you are using the device for just the essential functions that are common in all financial calculators, then you can opt for an affordable unit. According to most users, the Texas Instruments BAII Plus and HP 10BII are best for introductory functions. 

However, they might be missing the advanced calculative functions that you’ll notice only if your work or syllabus covers those functions. But if you’re an undergraduate student or enrolled in the MBA program, then it’s best to switch to the higher-end models. Getting the advanced unit will help you solve many of the problems in your Financial Management paper. 

On the other hand, you should bear in mind that as a financial professional, you’ll be using spreadsheets for most problems. Thus, a fancy model might be more than what you’ll require in such cases. Make sure that you know clearly why you’ll be using the financial calculator because it will guide you correctly during the purchase.

  1. Are financial calculators allowed for certification exams?

If you’re enrolled in one of the reputed institutions for a certification program, you might be aware of their policies that ban the use of specific calculators. In most cases, it refers to the units that can practically store text. Therefore, you should go through the policies carefully before you make an investment.

Here’s a list of some of the most globally accepted and reputed certifications in Financial Management for which you’ll require a financial calculator:

  • CFA Institute
  • FINRA Exams
  • CFP Board of Standards
  • The Society of Actuaries
  • Investment & wealth Institute Certification Exam

For each of these examinations, there is a specific set of rules which need to be followed in terms of the calculator that you can use. So, do keep an eye out for them because some of these exams have only specific model numbers that are accepted inside the center.  

  1. Do you need a calculator with scientific or graphing functionality?

If you want a financial calculator that features some of the advanced mathematical and scientific functions along with graphics, then a reasonable budget is essential. The top contenders with such advanced functionality are the TI 83 Plus and TI 84 Plus that comes with a high price tag. 

Whereas Hewlett Packard also makes stunning scientific calculators, but their financial units don’t have any of the graphics functionalities. Even though HP financial calculators are not the go-to for advanced math or science subjects, it’s ideal for the basic functions. 

On the whole, a financial calculator is a must for students and working professionals who belong to the Finance Management field. That’s mainly for completing the routine calculations. But when it comes to graphic functions, it isn’t one of the main requirements, especially for those who depend on spreadsheets for better analysis.  

  1. How much do you want to spend?

It’s best to opt for a financial calculator that has been priced according to the quality and features that it offers. When you look through the online shopping portals, you’ll be able to land a great bargain, especially during the sale period. And you can find quality units within a range of $30 to $100, which is a considerably good deal.

 If you don’t need large memory storage, graphing, or advanced financial functions, then you should stick to the budget-friendly units. In the end, the focus should be on choosing a model that will be helpful in your finance and math classes. 

Moreover, when you’re clear about the functions that you need in the financial calculator, you’ll be able to put your money in the right place. This will keep you from having to purchase two separate units, one for practice and another for classroom.  


After going through the buyer’s guide, it must have become easier to narrow down a few models based on its functionality, price, and usage. However, it’s essential to weigh out the pros and cons carefully for making an informed decision. 

With that being said, it’s best to get feedback from your faculty as to which unit will be acceptable for all the classes. And now that you have come to the end of our guide, we hope it has helped you find the answers that you have been seeking.  

So, go ahead and pick the calculator, which you know is ideal for your next finance class!
