Comparison assumes the same monthly principal-and-interest dollars are paid on both paths. On the sweep HELOC, the cash offset means a smaller share of each payment goes to interest, so more falls to principal and the line pays down faster. Savings scale directly with average cash balance; low balances produce little to no benefit.
