What are CFA Allowed Calculators?
The CFA (Chartered Financial Analyst) program is a globally recognized, graduate-level investment credential. A critical component of the CFA exam is the use of a financial calculator. However, the CFA Institute strictly limits which calculators candidates are permitted to use during the exam. This policy ensures fairness and prevents any candidate from having an unfair advantage due to advanced calculator functionalities. Currently, only two families of calculators are allowed: the Texas Instruments BA II Plus (including the BA II Plus Professional) and the Hewlett Packard 12C (including the HP 12C Platinum).
These CFA allowed calculators are specifically designed for financial calculations, making them indispensable for topics like Time Value of Money (TVM), cash flow analysis, bond valuation, and statistical analysis. Understanding the nuances of each calculator is crucial for efficient problem-solving under exam conditions.
Who Should Use This CFA Allowed Calculators Comparison Tool?
