Understanding Loan Payments

When you take out a loan, you need to understand how your monthly payments are calculated and what you're actually paying over the life of the loan.

The Loan Payment Formula

Monthly loan payments are calculated using this formula:

M = P [ i(1 + i)^n ] / [ (1 + i)^n โ€“ 1 ]

Where:
โ€ข M = Monthly payment
โ€ข P = Principal loan amount
โ€ข i = Monthly interest rate (annual rate รท 12)
โ€ข n = Number of months

Types of Loans

  • Car loans: Typically 3-7 years, secured by the vehicle
  • Personal loans: Unsecured, 1-7 years, higher rates
  • Student loans: Often have grace periods and income-based repayment
  • Mortgages: 15-30 years, secured by property
Example: $25,000 car loan at 5% interest for 5 years:
โ€ข Monthly payment: $472
โ€ข Total paid: $28,300
โ€ข Total interest: $3,300

Factors That Affect Your Loan Payment

  • Credit score: Better score = lower interest rate
  • Loan term: Longer terms = lower payments but more interest
  • Down payment: Larger down payment = smaller loan amount
  • Interest rate type: Fixed vs variable rates
