HELOC example
This worked example compares available home equity with a lender-style CLTV cap to estimate how much home equity line capacity may be available.
Calculated answer
With a home value of $600,000 and a current mortgage balance of $270,000, the estimated available HELOC limit is $210,000. A requested line of $40,000 implies an approval buffer or shortfall of $170,000.
Maximum HELOC = (home value × CLTV cap) - current mortgage balance
The shared HELOC math compares total secured debt allowed under the CLTV assumption with the current mortgage balance, then estimates the interest-only cost of the requested line amount.
| Year | Contributions | Interest / Growth | Ending Balance |

Total home equity is simply home value minus the mortgage balance, but lenders usually cap borrowing below that full equity amount.
Worked examples are useful for showing how CLTV policy can materially shrink or expand the amount a homeowner can actually request.
