Decision Guide
What this calculator helps you decide
Model the payment first, then use these checkpoints to decide whether this product structure still fits the situation.
- Best for
- Equity-capacity planning
- Hidden variable
- Rate and draw structure
- What to compare next
- Collateral tradeoff
- Use another tool when
- No home collateral is desired
This tool estimates how much borrowing room home equity might create under common CLTV assumptions.
Many HELOCs begin with interest-only draws, so the illustrative payment here is only one part of the real decision.
After the estimate, compare the lower secured rate against the slower funding and home risk.
If the borrower wants speed or no lien on the property, compare the personal-loan math instead.
Consider instead
You may need a different comparison if
- !Use the personal-loan calculator when speed and no-collateral funding matter more than the lowest APR
- !Use the home-improvement loan page when the project size fits the unsecured range and needs fast funding
How the HELOC calculator works
Available borrowing is driven by CLTV: lenders cap the combined mortgage plus new equity line at a percentage of the home value.
The payment estimate here uses a standard amortized payment for illustration, even though many HELOCs have interest-only draw periods.
HELOC vs. unsecured personal loan
HELOCs usually offer lower rates but take longer to close and use your home as collateral. Personal loans are faster and unsecured, but usually cost more.
HELOC & Home Equity Calculator FAQ
- What does CLTV mean?
- CLTV stands for combined loan-to-value. It measures your existing mortgage plus the requested new line against the property value.
- Why is my desired amount reduced?
- If the amount you want would exceed the CLTV cap, the calculator lowers it to the maximum allowed by the current inputs.
- Is this a HELOC offer?
- No. It is an illustration. Actual HELOC or home equity offers depend on appraisal, credit, occupancy, and lender guidelines.
