Best Financial & Business Office Calculators of 2025

"I find this calculator to be the official approved calculator for CFA exams, which gives me confidence in using it. The intuitive layout makes navigating complex calculations easy. Plus, battery replacement is super simple, reducing stress on exam day. It's reliable, accurate, and perfect for finance, both in studying and professionally. I highly recommend it!"

"Having both this model and the regular BA II Plus, I notice the build quality on this one is much better. Both have similar functionalities but share some weaknesses. For instance, you cannot press keys until the previous key is released, which can lead to errors if you're typing quickly. However, it’s allowed on the CFA exam and has most finance-related functions readily available."

"I bought the Texas Instruments BA II Plus Professional Financial Calculator for my finance exam last semester, and it has been incredibly useful. I can handle math and financial problems efficiently. It saves me a lot of time on complex equations, and I managed to achieve a perfect grade thanks to it. The calculator is very attractive and has a solid feel, consistent with its metal look. I would definitely recommend it for anyone in finance!"

"I found the calculator to be functional; however, the instruction book was only in Spanish, and I would prefer an English version."

"This is a product of the 'Old School' that will always be relevant. Excellent overall!"

"I purchased this calculator since my certification program mandates this specific model for proctored exams. While it performs well and has some added features compared to my Texas Instruments BAII, I noticed it feels less sturdy. My Texas Instruments has lasted 8 years without issues, and this one requires two batteries instead of one."

"The only drawback is that they sent me three copies of the usage instructions, and they are all in a foreign language—nothing in English."

"It's very complete and from a good brand. I liked the detail of the case."

"Compared to the HP-12C, this calculator is like its elder brother, offering 399 steps for programming versus the 99 steps of the 12C. It's much faster, supposedly six times faster, which makes it worth buying. For $40ish, it feels like an excellent buy!"

"Initially, I was a bit frustrated with the Reverse Polish Notation (RPN) on the HP 12c Platinum, but I've come to appreciate its efficiency. In a test-taking environment, it saves me time, which is invaluable. The manual is great and provides everything needed to maximize the calculator's potential."

"I prefer the HP 12c series because it looks like a tool for professionals, unlike other options that look like toys. After using the HP 10bII, I realized the 12c Platinum was a much better fit for my industry exams. Although the build quality isn’t as high as older models, it’s still better than its peers. You won’t regret choosing this calculator!"

"This calculator works just as it should, just like the original I bought 30 years ago. Last year, I purchased another one, but several months later, the buttons didn’t always register my inputs. Rarely could I get consistent results. Thankfully, this was a quick fix."

"I find this calculator to be incredibly easy to use. It handles numerous mathematical calculations and lasts for years. This is my fourth calculator over 40 years, and I can confidently say it's the best financial calculator I’ve ever owned!"

"The HP 12C has earned its legendary status for a reason. It’s the gold standard financial calculator, and I appreciate its durability. After trying the 12C Platinum, I quickly returned to this model. The battery life is impressive, lasting between three to five years, and the display is easier to read than most others."

"As a student in a scientific field, I find the HP Prime Scientific Graphing Calculator to be an indispensable tool for my studies. Its wide range of functions makes scientific calculations easy, and I appreciate the large, vibrant touchscreen for clear graphing and data interpretation."

"After struggling with a basic calculator in Algebra 2, I decided to invest in this one. I can't express how much I love it! The copy and paste feature is incredibly convenient, and I enjoy catching teachers off guard when they think I'm on my phone. The battery lasts me about 6-8 days, which is impressive."

"I'm really pleased with this calculator. It has a lot of features and has been perfect for my engineering work. I've replaced my old HP35 with it, and I can confidently say it's one of the best calculators out there, especially for the price!"

"This calculator is perfect for all my financial and accounting needs!"

"I bought this for my daughter's finance class. It's lightweight, easy to use, and affordable!"

"This calculator is exactly what my son's college professor required. It works great and is essential for his classes!"

"I've been using HP 12C calculators for over 25 years. My previous one finally wore out, and this replacement meets all my needs. The keys are responsive and provide excellent feedback. All financial functions operate smoothly. It's a must-have when I'm away from my computer or app."

"I purchased my first HP 12C many years ago and needed a second one. It's just as impressive as the original. This calculator remains an incredible tool for financial calculations."

"I'm thrilled that this calculator is still available. The Platinum Edition features a faster chip and retains the same reliability I relied upon for years in business. It's especially effective for amortization and computing payments."

"I love this calculator! I'm currently enrolled in a corporate financial management class for my MBA, and it's been a real lifesaver. It's simple to set up and user-friendly. I even bought a second one for my home! While I mainly use it for school, I believe anyone would find it a great buy."

"This product is exactly as described and it works wonderfully! I just needed a screwdriver to change the batteries. The protective case for the keys is a nice touch. It's been a fantastic tool for my financial accounting class, and it arrived quickly!"

"Once I got the hang of it, this calculator works really well! The condition matched the description perfectly, and it arrived on time. Although I purchased it for school, I can see it being invaluable for my financial tasks in the future!"

"This product gets the job done and behaves as I expected."

"I really appreciate the confident and trusted feel of this amazing instrument! It truly delivers!"

"For my Finance Management class, this calculator is very easy to use and understand. It honestly does what I need!"

"This calculator is just the right size and lightweight, making it easy to carry in my bag. I bought it the night before my real estate licensing exam, and even without the instructions, I remembered the basic formulas. It truly helped me, and I passed the test, which I was most worried about."

"I find this to be the ideal affordable amortizing calculator for those over 40. The large display and buttons make it easy to use, especially for those with visual challenges. It's super easy to turn on and off, which is a must for a battery-operated device. I’m very satisfied with this purchase."

"This lightweight calculator is relatively easy to operate. I haven’t yet mastered all its functions since I’m focused on my preparatory materials, but I believe it’s a great little calculator for the price."
