TI BA II Plus Financial Calculator Formula

The core logic follows the standard Time Value of Money (TVM) equation, assuming payments occur at the end of each period (Ordinary Annuity):

PV + PMT × [(1 – (1 + r)⁻ⁿ) / r] + FV / (1 + r)ⁿ = 0

Where r is the periodic interest rate (I/Y ÷ 100).

Variables:

  • N: Total number of compounding periods (e.g., years or months).
  • I/Y: The annual interest rate expressed as a percentage.
  • PV: The current lump-sum value. Usually, a loan amount is positive, while an investment/outlay is negative.
  • PMT: The amount of periodic payment that stays constant.
  • FV: The cash balance you want to attain after the last payment is made.

What is the TI BA II Plus Financial Calculator?

The TI BA II Plus is one of the most popular financial calculators used by business professionals and students worldwide, particularly those pursuing the CFA (Chartered Financial Analyst) designation. It is designed to handle complex calculations including IRR, NPV, and amortization.

This digital version emulates the “TVM Worksheet” functionality, allowing you to solve for any one of the five variables (N, I/Y, PV, PMT, FV) by providing the other four. It strictly adheres to the cash flow sign convention where money leaving your pocket is negative and money received is positive.

How to Calculate TI BA II Plus (Example)

Suppose you want to calculate the monthly payment for a $30,000 car loan at 5% annual interest over 5 years (60 months):

  1. Set N to 60 (5 years × 12 months).
  2. Set I/Y to 0.4167 (5% ÷ 12 months).
  3. Set PV to 30,000 (The loan you receive).
  4. Set FV to 0 (You want to pay off the loan).
  5. Click Calculate to find PMT.

Frequently Asked Questions (FAQ)

Q: Why is my result negative?
The calculator uses sign convention. If you receive a loan (Positive PV), the payments you make must be negative (Negative PMT) to balance the equation to zero.

Q: How do I calculate for monthly periods?
Divide the annual I/Y by 12 and multiply the number of years by 12 to get N.

Q: Can I solve for the interest rate (I/Y)?
Yes, if you provide N, PV, PMT, and FV, the tool uses an iterative numerical method to solve for the interest rate.

Q: Does this handle “Begin” mode?
This specific version assumes “End” mode (Ordinary Annuity), which is the default for most consumer loans and mortgages.
