CALCULATE: Amortizing by Hand

Sharif aced his interview and just landed his first full-time job. Unfortunately, his workplace is a 30-minute drive outside of the town, and the buses don’t run there, so he needs to buy a car. He’s found a used car that will meet his needs for $13,500. He has $1,000 for a down payment, and will pay the rest with an auto loan. With a 3.5% APR and 3-year term, he calculates his monthly loan payment to be $366.28. Answer the following questions about Sharif’s car purchase.

VIDEO: What is Amortization?

Watch this short video clip to understand the basic terminology and process of amortizing a loan.

Obavezno

What two components make up your monthly loan payment?

Why do you think it is helpful to have an amortization table for your loan?

VIDEO: Learn to Create an Amortization Spreadsheet

A helpful tool when creating an amortization table is a spreadsheet. This will allow you to complete repetitive calculations more efficiently and save you having to write each value individually. Watch the video on creating a custom amortization table in Google Sheets. Follow along and pause the video as needed.

A recursive sequence is a sequence in which terms are defined using one or more previous terms. What value in this amortization calculation is a basis for a recursive sequence?

ACTIVITY: Using an Amortization Table

An amortization table is useful in that it shows you the whole life of the loan and allows you to look at different pieces of information. First, expand your table for Sharif’s loan, and then answer the questions.

Explain why this does not necessarily line up with half the initial balance.

Suppose Sharif receives a tax refund and contributes an additional $500 on his 10th payment. What will be the general impact on Sharif’s amortization values by making this single larger payment?

Obavezno

How can the graph help you to understand Sharif’s loan balance and interest in a better way than the table of values?

What amounts will be fixed in this scenario? Which amounts may vary?

Make a copy of this template, create your own amortization spreadsheet for Zeke that doesn’t have a specific term and where he will vary the payment amounts. Re-paste the link to the spreadsheet below. Be sure your sharing permissions allow your teacher to view it.

Adjust the payment amount and see how it changes the time to pay off the loan. Approximately how large would his payments have to be to pay off the card in exactly 2 years?

Using the compound interest formula provided and the fact that student loan interest compounds daily, how much would she owe on her loans when she graduates after 4 years of college including any interest?

Plug this value in your spreadsheet to find out what her monthly payment would need to be under the standard repayment plan for just these loans if she took out no more.
