Texas Instruments BA II Plus Financial Calculator

Solve time-value-of-money calculations / Generate amortization schedules / Includes trigonometric functions, natural logarithms, powers analysis Gives business professionals and students access to powerful features such as cash-flow analysis and advanced, list-based statistics

We're definitely taking this along with us the next time we shop for a house. Though it takes a little effort to master the collection of financial worksheets available on the Texas Instruments BA II Plus, you'll be glad you invested the time and money in this fine financial calculator.

The BA II Plus operates in standard calculator and worksheet modes. The standard mode lets you perform common math as well as operations involving the time value of money--that is, applications such as mortgages or annuities in which payments are equal and evenly spaced. You can also perform trigonometric functions in standard mode.

The more hard-core worksheet mode includes tables for amortization, bond, depreciation, and compound interest. If you're not familiar with such calculations, the very helpful user's manual will guide you through the process. All previous worksheet values are stored in memory, so you don't have to retype all the bond maturity or cash flow analysis figures.

The average user who wants to calculate a basic loan payment will be more comfortable working in the standard calculator mode. We were using the BA II Plus tools for calculating basic interest and payment periods within minutes. Still, it's good to know that the more advanced features are available for those who require heavy-duty financial computing.

Finance students and average users alike will find much to like in the Texas Instruments BA II Plus. --John Frederick Moore

Texas Instruments TI-30X IIS 2-Line Scientific Calculator

There are many inexpensive scientific calculators on the market, but few boast the two-line display and other advanced features users get with the TI-30x IIS. The display shows the equation you are creating on the top line, and the numbers or symbols you are currently entering on the second line. Once the equation is solved, the results are displayed on the second line, and you can use the four arrow keys on the front of the calculator to edit the original equation in any way you like for a recalculation. Better still, pressing the up arrow repeatedly lets you browse through a cache of dozens of previous calculations, meaning you can look back to see the answer to a problem you solved two minutes ago, two days ago, or whenever.

The device uses solar power when possible but can fall back on the internal batteries (which are included) if there isn't enough light. The buttons wiggle around a little too much and require a firm keystroke to register input, but the fact that input can be followed by looking at the output on the first line helps to cut down on mistakes. There is a shift key that doubles the functions of most buttons, and although the TI-30X IIS isn't festooned with as many buttons or functions as some other calculators we've tested in this price range, it's still very capable. There are three angle modes (degrees, radians, and grads), scientific and engineering notation modes, and even one- or two-variable statistical modes. Five variables can also be assigned to their own memory slots. The documentation is lacking, as everything is presented on a single folded sheet of paper, but Texas Instruments did manage to pack several illustrated examples on the page. The calculator comes with a snap-on cover that fits on the back of the device when you are using it. The calculator carries a one-year limited warranty. --T. Byrl Baker

Pros:

• Two-line display
• Relatively inexpensive
• Handles one- and two-variable statistical calculations

Cons:

• Weak documentation
• Buttons wiggle a bit too much

The new two-line TI-30X IIS with the memory retention feature retains previous entries, memory values, and individual statistical elements, and is a great value for general math, algebra, trigonometry, statistics, science, and much more. It allows you to enter, delete, insert, and edit individual statistical data elements, and displays trigonometric functions in degrees and radians. It performs common and natural logarithms, fractions and fraction/decimal conversions, and degrees, minutes, seconds/decimal degrees conversions. The calculator features durable plastic keys and a protective cover, with a quick reference card and guide for easy assistance.
