## Customer Reviews

### ⭐⭐⭐⭐⭐ The Best Quality Real Estate Calculators Are From Calculated Industries.  The 5 I have Are Stick Working after 30 Years of Use
*by E***S on August 11, 2014*

I just adore this calculator. I have been a real estate broker for 30 years and think that this calculator is more practical that the HP calculators that were so popular in the 80's. It is easy to use and gives me what my clients need to determine their mortgage payments, down payments needed with interest rates. You will not go wrong with this real estate calculator. I have bought 5 of them through the years with each one having improvements and more features. This is the best one and I like the others. Buy it! I have purchased tons and tons of calculators and this is by far the best in quality that works. I have 4 other real estate calculators from this company that are still working well with only battery changes, but being high-tech I like to have the new models when they come out, not to mention that I have one in my purse, one at home in my drawer, 2 at the office and now this one.. I Still have my first model the Classic and it is 30 years old to date. None of them have needed any repairs and the only thing I have to do is change the batteries and this is not very often, like years go by before I have to do so. So I encourage anyone to buy Calculated Industries calculators, whether you are a real estate agent or not, there is always a specialty calculator for you.I am so sick of those cheap calculators that do not stand the test of time. Calculated Industries has my loyalty for life.

### ⭐⭐⭐⭐⭐ Simple, Amazing
*by W***M on January 31, 2012*

As I decide I was going to go back through my entire purchase history to write reviews for other potential customers, I decided to stay away from two types of reviews: personal electronics (because the industry changes so rapidly and my review, although still valid for that product, would be seen by exponentially less people as months go on), and personal items (because the world doesn't need to know why I love a brand of adhesive bandages used to prevent chafing nipples when I run).I decided to write a review on this product, however, even though it closely fits into the "personal electronics" category.This is a simple calculator that anyone (yes ANYONE) should buy. It brings the complexity of time-value-of-money to any layman's hands. I actually first saw this calculator when I went shopping for my first mortgage. I saw the loan officer using this and was able to spit hypothetical numbers at me faster than I could comprehend them. I went home, bought this, and was armed for our next meeting.Pros:1. FANTASTIC customer support. Even after reading the manual, I had a question that I couldn't figure the answer to. I emailed the company and within a few days received a complete answer. It was nice I never received an automated email from them, nor did I get an email that gave me a bunch of links to where I could find the answer. The email I received was from a representative who knew the right answer and wrote the email as if to talk me through what to do. At no time did I feel stupid or that I was bothering them. This was impressive.2. Simple calculator combined with an extensive time-value-to-money calculator. Many specialty calculators (graphing, for example) have so many buttons that it would confuse the casual user, making him feel as if he only uses 10% of the calculator's potential at any given time).3. Easy to learn. I took about 20 minutes and sat down when I first got this to learn how it works. I am of average intelligence and simply committed to learning this. The ease-of-use allowed me to talk on the phone with a loan officer many times and crunch numbers with her -- throwing numbers back and forth.4. There is a small pocket built into the back of the calculator where the user manual sits so that if any information is forgotten, it can quickly be referenced. This pocket tucks the manual away nicely so that it doesn't get torn.5. iOS app with the software to run this same calculator. I still prefer having the calculator in my hand, though. The option is available, though.6. This may seem petty, but I love the 000 button. It saves time from typing three zeros all the time. One wold think it is silly to write this as a "pro" but I find this button very helpful.Cons:1. Although there are one or two features I would like to see added (such as a yearly amortization schedule - for some reason, I can only get it to show me monthly), I can honestly not think of any cons at this time.2. Sometimes I get frustrated with the payments per year option and how to change it. Admittedly, this is my fault.Bottom line: Essential for the casual user through the professional banker. If you are going to spring for a simple calculator, get this one (you won't regret it).
