Forget the old ‘2% rule’
There is no universal rule that refinancing only makes sense after rates fall by two percentage points. The right comparison depends on the existing loan, proposed loan, closing costs, payment change, remaining term, loan balance and how long the borrower expects to keep the new loan. A smaller rate improvement can still be worthwhile in some situations, while a larger rate drop can still be a poor trade if costs are high or the borrower expects to sell soon.
