Consolidated monthly payment
—
Enter your unsecured debts (balances, rates, payments) against a consolidation into mortgage borrowing to see both numbers that matter: the monthly saving — usually substantial — and the total lifetime cost, which can run higher if short expensive debt is stretched across a long mortgage term. This calculator shows both, deliberately.
Consolidation converts unsecured debt into debt secured on your home — a real trade with real benefits and real warnings, which our second charge page treats fully. The calculator's job is making the trade visible before anyone signs it.
Mortgage rates run far below card and loan rates, so the monthly payment falls dramatically on consolidation — that part is real. But stretching a £15,000 card balance across a 25-year mortgage term can cost more in total interest than the card would have, despite the lower rate: term length is the quiet variable the monthly figure hides.
The fix is structural: consolidate onto a shorter sub-term where products allow, or overpay the consolidated slice deliberately — capturing the rate saving without the term stretch.
Consolidation runs through three vehicles — capital-raising remortgage, further advance, or second charge — with the right one depending on your current deal's rate and ERCs (the keep-your-rate logic our second charge page maps). The discipline matters more than the vehicle: consolidation that precedes rebuilt card balances relocates the problem onto your home and adds a storey.
We advise on the whole picture — vehicle, structure, and honestly whether consolidation serves you at all — before arranging anything.
