An app on the Apple App Store is also available by Texas Instruments mirroring the Calculators design and functionality. From to sometime after , TI produced the BA also known outside North America as the TI , which was a basic desktop calculator with the addition of dedicated cost, margin, and sell calculation buttons.
Early models included a built-in clock module, which was removed for the revision. The short-lived TI Profit Guide had similar functions in a pocket calculator size.
The BA was targeted at students studying finance and was available from to the late s. It was the most affordable calculator for time-value-of-money calculations [ citation needed ].

Use the straight-line depreciation method to compute the depreciation expense, remaining book value, and remaining depreciable value for the first two years.
Page 66 Depreciation Worksheet Page Statistics Worksheet Statistics Worksheet The Statistics worksheet performs analysis on one-and two-variable data with four regression analysis models.
To access statistics variables, press or ". Page Regression Models For two-variable data, the Statistics worksheet uses four regression models for curve fitting and forecasting.
Model The calculator interprets the value as the dependent variable. Statistics Worksheet nn, the value for. The calculator determines the values for curve that best fits the data.
Correlation Coefficient The calculator also determines measures the goodness of fit of the equation with the data. Generally: is to 1 or -1, the better the fit. Page Computing Statistical Results To compute results based on the current data set, press repeatedly after you have selected the statistics calculation method.
The calculator computes and displays the results of the statistical calculations except for X' and Y' automatically when you access them. Page 72 Statistics Worksheet Page Interest Conversion Worksheet To select interest conversion variables, press or ". Page 77 The annual effective interest rate interest rate that you actually earn for the period of time stated.
Page Date Worksheet To compute a value for the unknown variable interest rate , press or " until calculator displays the computed value. What is the annual effective interest Page 79 Note: The calculator categorizes variables by their method of entry. Page Profit Margin Worksheet To change the day-count method setting, press until displayed. The calculator displays the computed value. Example: Computing Days between Dates A loan made on September 4, defers the first payment until November 1, All Breakeven worksheet variables default to zero.
Press " Page 83 Repeat step 3 for each of the remaining known variables. Page 86 Other Worksheets If this number contains a fraction, raise it to the next whole number; Additional calculations use the internal value, not the value displayed.
If the eleventh digit of the result is 5 or greater, the calculator rounds the result to the next larger value for display. Page Replacing Battery Note: The calculator cannot retain data when the battery is removed or discharged.
Choosing the Number of Decimal Places Displayed The calculator stores numeric values internally to an accuracy of 13 digits, but you can specify the number of decimal places you want to display. Choosing the Angle Units The angle unit value affects the display of results in trigonometric calculations. Using Dates The calculator uses dates with the Bond and Date worksheets and the French depreciation methods. After you key in the date, press! Choosing Calculation Methods When you choose the chain Chn calculation method, the calculator solves problems in the order that you enter them.
Overview of Calculator Operations 5. Performing a Hard Reset You can also reset the calculator by gently inserting a pointed object such as an unfolded paper clip or similar object in the hole marked RESET in back of the calculator. Clearing Calculator Entries and Memories Note: To clear variables selectively, see the specific worksheet chapters in this guidebook. To Press Display Begin the expression. Key in the correct number.

Parentheses 9: Use parentheses to control the order in which the calculator evaluates a numeric expression in division, multiplication, powers, roots, and logarithm calculations. Scientific Notation ; When you compute a value in the standard-decimal format that is either too large or small to be displayed, the calculator displays it in scientific notation, that is, a base value or mantissa , followed by a blank space, followed by an exponent.
Overview of Calculator Operations Memory Operations You can store values in any of 10 memories using the standard calculator keys. Clearing Memory Clearing memory before you begin a new calculation is a critical step in avoiding errors. Storing to Memory To store a displayed value to memory, press D and a numeric key 0—9.
Recalling From Memory To recall a number stored in memory, press J and a numeric key 0—9. Note: The recalled number remains in memory. Subtract the displayed value from the value stored in DB 3 memory 3 M3. D6 5 Raise the value in memory 4 M4 to the power of the D; 4 displayed value.

Accessing Prompted-Worksheet Variables After you access a worksheet, press or " to select variables. Compute-Only Variables You cannot enter values manually for compute-only variables, for example, net present value NPV.
Time-Value-of-Money and Amortization Worksheets Using the TVM and Amortization Variables Because the calculator stores values assigned to the TVM variables until you clear or change them, you should not have to perform all steps each time you work a problem.
Clearing the Unused Variable For problems using only four of the five TVM variables, enter a value of zero for the unused variable. Entering Positive and Negative Values for Outflows and Inflows Enter negative values for outflows cash paid out and positive values for inflows cash received.
Entering Cash Inflows and Outflows The calculator treats cash received inflows as a positive value and cash invested outflows as a negative value. Generating an Amortization Schedule The Amortization worksheet uses TVM values to compute an amortization schedule either manually or automatically. Generating an Amortization Schedule Manually 1. Generating an Amortization Schedule Automatically After entering the initial values for P1 and P2 , you can compute an amortization schedule automatically.

Clearing Calculator Entries and Memories Using Worksheets: Tools for Financial Solutions Entering Cash Inflows and Outflows Generating an Amortization Schedule Example: Computing Basic Loan Interest Examples: Computing Basic Loan Payments Examples: Computing Value in Savings Example: Computing Present Value in Annuities The Texas Instruments Business Analyst series is a product line of financial calculators introduced in BA calculators provide time value of money functions and are widely used in accounting and other financial applications.
Though originally designed specifically for financial use, current models also include basic scientific calculator and statistics functions. It provides basic scientific calculator functionality alongside its financial functions, and provides most of its financial functions in the form of worksheets, where values are input as variables in a table; when a computation is requested, the calculator plugs the values from the worksheet into the appropriate internal expression and returns the requested result.
