When lenders provide borrowing options, comparing monthly payments alone can lead to costly mistakes. A loan with a lower monthly payment often costs significantly more in total interest due to an extended term.
The Three Numbers That Matter
- Monthly Payment: Your immediate cash flow commitment.
- Annual Percentage Rate (APR): The true annual borrowing cost, including upfront origination fees.
- Total Lifetime Interest: The total dollar cost paid to the lender above the borrowed principal.
