2nd Mortgage Loan Calculator
For many homeowners, a second mortgage is a way to unlock the equity in their property without selling. Whether you need funds for home improvements, debt consolidation, education, or big expenses, a 2nd mortgage allows you to borrow against your home’s value.
But before applying, you should know:
- How much can I borrow with a second mortgage?
- What will my monthly payments be?
- How much interest will I pay over time?
- What’s the total cost of the loan?
That’s where the 2nd Mortgage Loan Calculator comes in. It gives you quick, accurate estimates so you can make smart financial decisions.
What is a 2nd Mortgage?
A second mortgage (also called a home equity loan or home equity line of credit – HELOC) is a loan secured against the equity in your home, on top of your first mortgage.
For example:
- If your home is worth $300,000 and your first mortgage balance is $180,000, your available equity is $120,000.
- Lenders usually allow you to borrow up to 80–85% of your home’s value, minus the first mortgage balance.
How the 2nd Mortgage Loan Calculator Works
This calculator estimates:
- Maximum Loan Amount – Based on your home’s value and equity.
- Monthly Repayments – Using the loan amount, interest rate, and term.
- Total Interest Payable – How much you’ll pay over the life of the loan.
- Total Loan Cost – Principal + Interest combined.
You’ll need to input:
- Home’s current value
- Balance remaining on your first mortgage

- Loan term (in years)
