Blended Rate Calculator

See the weighted-average rate across your stacked debts — the real cost you are carrying before any refinance.

If you are carrying a mortgage alongside higher-rate debt — a line of credit, credit cards, a car loan — your blended rate is the number that matters. A refinance often works by rolling that expensive debt into one lower mortgage rate. Add each debt below to see where you stand today.

Blended rate
The single average interest rate across all your debts, weighted by how much you owe on each. It shows the true cost you are carrying.
Weighted average
An average that gives bigger debts more influence — a large balance at a high rate moves the blended rate more than a small one.
