Compare the fixed payment with a HELOC and read how home-equity borrowing works before signing.

Frequently asked questions

Is a home equity loan fixed rate?
This calculator models a fixed rate. The lender’s note controls whether the actual product is fixed or variable.
Does it include my first mortgage?
No. It estimates the second loan by itself. Add both payments to understand the household obligation.
What determines how much I can borrow?
Lenders consider value, existing liens, combined loan-to-value, income, credit, and underwriting rules.
Is the loan secured by my home?
Yes. Missed payments can create foreclosure risk, so preserve a payment buffer.
