What is actually borrowable

Equity owned and equity lendable are different numbers. A lender caps what may be owed against the home in total, not what you have built up.

How this calculator works

Two separate questions: how much you may borrow, and what borrowing it costs.

available = value × CLTV − mortgage balance
M = L · r ÷ (1 − (1 + r)−n)

The first line is the constraint and the second is the cost. Note that the equity you own does not appear in the first one — what the lender allows is a share of the home’s value, less what is already owed against it.

What is assumed

  • A fixed rate, fully amortizing, with no closing costs financed into the balance.
  • The home value you enter is what an appraiser would agree to. Lenders lend against their valuation, not yours.
  • No tax treatment of the interest.

Questions people ask

Not all of it. Lenders cap what may be owed against the home in total — the combined loan-to-value — commonly at 80–90%. On a $600,000 home with $380,000 owed you have $220,000 of equity, but at 85% CLTV only $130,000 of it is lendable. The rest is a cushion the lender keeps between your debt and the market.

An estimate for planning. It is not a loan offer. Combined loan-to-value limits, rates and closing costs vary by lender and by your circumstances.
