Refinancing in Plain English
Refinancing means replacing an existing loan with a new one — ideally at a lower interest rate, a shorter term, or both. The new loan pays off the old one, and you make payments on the new terms. It works for mortgages, auto loans, student loans, and personal loans.
When Refinancing Saves Money
If you can get a rate at least 1–2 percentage points lower than your current loan, refinancing usually pays for itself within the first year. A $20,000 auto loan at 8% refinanced to 5% saves roughly $1,800 over 48 months.
Use the Loan Calculator on DebtCalc to compare your current loan against a new offer. Enter both scenarios and compare total interest paid and monthly payment differences.
When It Doesn't Make Sense
Refinancing has costs — origination fees, application fees, sometimes prepayment penalties. If savings don't exceed these costs, it loses money. Extending the term for a lower monthly payment often means paying more total interest even at a lower rate. Another trap: refinancing a loan almost paid off. With 12 months left on a car loan, interest savings are minimal compared to the hassle and fees.
The Rate Check
Lenders like SoFi let you check your rate with a soft credit pull that doesn't affect your score. The general rule: if the rate drop saves more than the fees cost and you keep the same or shorter term, refinancing makes sense.
