Home Equity Loan calculator
Available equity is not loan approval or a safe spending budget. Review the new payment, fees and combined debt; failure to repay can put the home at risk.
- Use a current property value and first-lien balance.
- CLTV is an entered assumption, not a universal lender rule.
- Review closing fees and whether the budget supports both loans.

How the home equity loan calculator works
Estimate a fixed home-equity loan payment and available borrowing room.
Available equity uses property value and a maximum combined LTV; payment uses fixed-rate amortization.
Read our calculation methodology and limitations.
Example
Start with the example scenario, then replace each clearly labeled field with values from your property, statement, quote, or project budget.
Does available home equity mean I can afford another loan?
- Estimated home value
- $500,000
- Existing mortgage balance
- $280,000
- Maximum combined LTV
- 80 %
- New home-equity loan
- $75,000
- Interest rate
- 8.25 %
- Loan term
- 15 years
- Estimated monthly payment
- $727.61
- Available borrowing room
- $120,000.00
- Combined LTV after loan
- 71%
- Total loan interest
- $55,968.95
Borrowing room is a modeled collateral limit, not approval. The second-lien payment still needs a budget.
These are fictional, editable assumptions—not market quotes or personal advice.
What affects the result
- Lenders use their own property value and CLTV limits.
- Closing costs may change proceeds.
- Your home secures the debt.
