Consumer Finance Concepts
Chapter Overview
Current Status: Finishing Chapter 5; starting Chapter 6 possibly on Thursday.
Main Focus: Consumer finance and related calculations will be the primary subjects.
Key Feature in Consumer Financing: Monthly payments are standard in most consumer finance transactions including car purchases and leases.
Consumer Financing Details
Monthly Financing Features:
Most consumer finance transactions involve monthly payments, whether it's a car lease or financing.
Financing can be confusing without credit card usage, as promotions often allow for deferred payments.
Example of Consumer Finance
Illustrative Purchase:
Financing on items such as notebooks ($300 - $500)-> promotional offers may allow for financing over defined periods.
Loan Parameters for Calculation:
Loan Amount: $10,000
Number of periods (5 Years)
Interest Rate: 14%
Loan Calculation Process
Understanding Loan Amount:
The loan amount is treated as a present value.
Payments are treated as a negative cash flow because they represent money going out.
Loan Lifecycle:
Present Value: $10,000 (viewed as a loan to the consumer from the perspective of the bank)
Future Value: Typically $0 unless stated otherwise (like residual payments at loan's end).
Payment Calculations
Need four inputs to calculate payments:
Present Value
Future Value
Interest Rate (14% annually)
Number of Periods (5)
Key Outcome:
Calculating payments helps determine annual amounts due to the bank.
Amortization Schedule
Definition of Amortization Schedule:
A detailed schedule illustrating payment breakdowns over time (interest vs. principal splits).
Structure of a Typical Amortization Schedule:
Columns: Year, Beginning Balance, Constant Payment, Interest Payment, Principal Payment, Ending Balance.
Calculation of Payments:
Payment Formula: Payment = (Interest Rate * Outstanding Balance)/12 + Monthly Constant Payment.
Understanding Payments
Components of Monthly Payment:
Interest Payment: Calculated as Outstanding Balance * Interest Rate.
Principal Payment: Total Payment minus Interest Payment.
Example Payment Breakdown:
First Year: $
Total Payment: $2,900
Interest: $1,400
Principal Reduction: $1,500
Ending Balance: $8,500 after the first payment period.
Implications of Amortization
Significance of Understanding the Amortization Schedule:
Knowing how much you have left and when you will be debt-free.
Relevant for tax purposes (interest payments on mortgages may be tax-deductible).
Mortgage Template Overview
Transitioning to the specifics of mortgage calculations:
Use of house values and down payments in calculating loan amounts required.
Standard Inputs for Mortgages:
Purchase Price: e.g., $250,000
Down Payment: Often requires 10-30% (20% = $50,000).
Loan Amount: Price - Down Payment = $200,000.
Payment Function Overview in Excel
Data Input for Calculating Mortgage Payments:
Interest Rates converted to monthly rates.
Payment function parameters include:
Present Value = Loan Amount
Rate adjusted monthly.
Output: Monthly payment amounts, structure an easy, clear approach to mortgage processing.
Long-term Mortgage Implications
Amortization and Loan Caveats:
Understanding how much is going towards principal versus interest is critical.
Comparative Analysis of Payments Over Time:
Analyzing how drastically the composition of payments changes over time (from mostly interest to more towards principal).
Impacts of Refinance:
A common practice is refinancing if rates drop, with a shift in interest percentages affecting payment dynamics.
Consideration During Refinance
When considering refinancing due to lower rates:
Assess the costs of paying off original loans versus potential savings from reduced rates.
Understand the balance remaining post ten years is crucial for financial insight.
Psychological Factors in Loan Decisions
It's essential to factor psychological elements in finance decisions like buying a home versus renting, including short-term versus long-term financial perspectives.
