Financial decision-making involves math - let’s build students’ confidence in both! Using graphing calculators in personal finance, students can learn to navigate financial formulas and get to the heart of thorny questions, like how much house can I afford? And how much should I be investing for retirement? Here's how you can get started using TI graphing calculators with NGPF activities.

The Finance Solver

To get started, we’ll focus on the Finance Solver. The Finance Solver is a versatile application that is found in many TI graphing calculators, including TI-84 and TI-Nspire calculators, that can be used to solve problems about loans and investments. 

If you’re not familiar with the Finance Solver yet, check out these introductory videos that walk you through how to access and use the Finance Solver, depending on your calculator.
