Equity feels like money in the wall. Banks see combined loan-to-value math, credit, income, and whether you’re trying to turn your kitchen into a casino. The ceiling is often lower than Zillow courage suggests—especially once a second lien payment joins the first mortgage you already have.
LTV in English
If your home is worth $520,000 and you owe $310,000, your equity headline is $210,000. Borrowing power is not that full amount—lenders cap combined debt against value. Toollabz models an 85% combined ceiling for a quick sketch: 0.85 × $520k − $310k ≈ $132k headroom before overlays tighten it.
Payment matters as much as approval
A fixed second amortizes like a car loan mentally—steady principal kill. HELOCs often start interest-only on draws, then surprise people later. Our calculator assumes a closed-end style payment so you see a conservative monthly if you fully amortize what you borrow.
Try your value, balance, desired amount, rate, and term in the home equity loan calculator, then compare with refinance scenarios if rate improvement is the real goal.
FAQ
Is interest deductible?
Depends on use of funds and current law. Ask a tax pro—don’t bet a kitchen remodel on a blog footnote.
Why didn’t I get the full 85%?
Risk-based adjustments, second-lien investor caps, and appraisal reality all shrink the box.
