How it works
Blended rate formula
(Bal1 x Rate1) + (Bal2 x Rate2) divided by (Bal1 + Bal2)
Weighted average by outstanding balance
When a second beats a refi
Borrower locked in at 3-4% on the first. Touching that rate to do a cash-out refi costs them hundreds per month.
A second at a higher rate still produces a lower blended payment when the first lien rate is low enough.
Use the refi comparison section to show the exact dollar difference side by side.
