Loan Amortization on the HP 17BII

This tutorial explains how to amortize a fixed-rate loan using the HP 17BII financial calculator. It guides users on calculating the principal and interest for individual payments or a range of payments. The article demonstrates using the calculator’s built-in functions to break down loan payments into principal and interest components and how to determine the remaining balance after each payment. Additionally, it briefly compares this method with using a spreadsheet for creating a full amortization schedule, highlighting the limitations and practical applications of the HP 17BII calculator's amortization functions.

TI 83 and TI 83 Plus Tutorial, Part II

Part 2 of a TI-83 calculator tutorial on calculating money value over time. It covers how to find present and future values of annuities (regular payments) and lump sums using the built-in TVM Solver app. The tutorial explains different annuity types (regular and due) and how to solve for missing variables like payment amount, interest rate, or number of periods. It also touches on perpetuities (infinite payments) and how to approximate their present value with the calculator.

TI 83 and TI 83 Plus Tutorial, Part I

This is the first part of a TI-83 calculator tutorial on performing time value of money calculations. It covers finding future and present values of lump sums using the built-in TVM Solver app. The tutorial explains how to enter data considering the calculator's cash flow sign convention and solve for missing variables like the number of periods or interest rate. It also teaches how to adjust the calculator's decimal places for better viewing.

HP 19BII Tutorial, Part I

The HP 19B is a fairly easy to use financial calculator that will serve you well in all finance courses. The 19BII can operate in either RPN (reverse polish notation) or algebraic modes. RPN is better in most cases, so I suggest that you choose that mode if you understand RPN. This tutorial will demonstrate how to use the financial…

Time Value of Money – Solving for i and N for Lump Sum Cash Flows

In the previous sections, we have seen how to calculate present values and future values of lump sum cash flows. However, in many cases you may need to solve for the number of periods or the interest rate. The purpose of this section is to show exactly how to do that. It is important to remember that we are using…

Loan Amortization on the HP 10BII+

In this tutorial we will see how to amortize a fixed-rate loan using the HP 10BII+ calculator from Hewlett Packard. Specifically, we will see how to calculate the amount of principal and interest for any particular payment, or range of payments. For example, you may wish to know how much your principal or interest payments will be for the first…

Annuity Due Formulas

These are the main formulas that are needed to work with regular annuity cash flows (Definition/Tutorial). Please note that these formulas work only on a payment date, not between payment dates. This is the same restriction used (but not stated) in financial calculators and spreadsheet functions. I use MathJax to display these formulas. You can click the equations to show…

Lump Sum Formulas

These are the main formulas that are needed to work with lump sum cash flows (Definition/Tutorial). I use MathJax to display these formulas. You can click the equations to show a zoomed version in a pop-up, or right-click on the formulas for additional options (e.g., to copy the equation as $\TeX$ or to choose the zoom settings). To Solve For:…

Loan Amortization on the HP 20b

Solving Problems with Non-Annual Periods on the HP 17BII

Many, perhaps most, time value of money problems in the real world involve other than annual time periods. For example, most consumer loans (e.g., mortgages, car loans, credit cards, etc.) require monthly payments. All of the examples in the previous pages have used annual time periods for simplicity. On this page, I’ll show you how easy it is to deal…

HP 10BII+ Tutorial, Part II

In the previous section we looked at the basic time value of money keys and how to use them to calculate present and future value of lump sums. In this section we will take a look at how to use the HP 10BII to calculate the present and future values of regular annuities and annuities due. A regular annuity is…

HP 10BII+ Tutorial, Part I

If the picture at right doesn’t match your calculator, you may have an original HP 10B or HP10BII (not the + version). These calculators differ slightly, so you may prefer the HP 10B tutorial. The Hewlett Packard 10BII+ is a very easy to use financial calculator that will serve you well in all finance courses. This tutorial will demonstrate how…
