Blended Debt Rate

It calculates your combined interest rate when you have two loans—such as a first mortgage and a second mortgage or HELOC. This helps you understand the real cost of borrowing.

Use it when you're structuring a piggyback loan (like an 80/10/10), combining a first and second mortgage, or have a large HELOC. It helps you evaluate if refinancing or combining loans makes sense.

It's the weighted average of two or more loan rates, based on the loan amounts. This gives you a single effective rate so you can compare against refinance or consolidation options.

Enter the loan amount and interest rate for both your first and second mortgage (or HELOC). The calculator shows your blended rate and total combined debt.

Not directly. It shows your total combined rate so you can compare it to current refinance offers. A lower refinance rate may make it worth consolidating the loans.

This calculator supports two loans. If you have more, calculate in pairs or contact your lender to help you combine the full structure.

No. It only calculates the effective blended interest rate. Use a refinance or full amortization calculator for payment comparisons.
