Debt Consolidation Calculator

Debt consolidation is the process of combining multiple debts into a single loan, typically with a lower interest rate or more manageable repayment structure. In New Zealand, this usually means taking out one personal loan or using a home equity loan to pay off credit cards, store cards, car loans, or other high-interest debts. Instead of juggling multiple payments and interest rates, you make one regular repayment to one lender. For example, if you have three debts — a $3,000 credit card at 22%, a $5,000 personal loan at 15%, and a $2,000 store card at 25% — consolidating them into a $10,000 personal loan at 12% reduces your average interest rate significantly and simplifies your finances. The total savings depend on the new interest rate, any consolidation fees, and the loan term. Debt consolidation is offered by most NZ banks, credit unions, and some specialist lenders.

Debt consolidation makes financial sense when it results in a lower overall interest rate, reduces the total amount you repay, or genuinely simplifies your financial management in a way that helps you stay on track. The ideal scenario for NZ borrowers is multiple high-interest debts (credit cards at 20%+, store cards at 25%+) being consolidated into a single personal loan at 10%–14%, with no significant increase in the total repayment term. It also makes sense if you are struggling to track multiple repayment dates and are at risk of missed payments damaging your credit file. However, consolidation does not always make sense: if the new loan has a much longer term, you may pay more interest overall even at a lower rate; if consolidation fees and charges are high; or if you lack the discipline to avoid accumulating new debt on the cleared cards.

While debt consolidation can be a powerful tool, there are several risks New Zealand borrowers should be aware of. First, if the consolidated loan has a longer repayment term, total interest paid may increase even if the rate is lower — always calculate the total cost, not just the monthly payment. Second, clearing credit cards and store cards through consolidation can be psychologically liberating, tempting some borrowers to re-use that available credit and accumulate new debt on top of the consolidation loan (known as reloading). Third, using your home as security for a consolidation loan (home equity loan) converts unsecured debt to secured debt — if you cannot repay, you risk losing your home. Fourth, some consolidation loans and finance companies charge high establishment fees (1%–3%) or early repayment penalties. Finally, consolidation does not address the underlying spending or budgeting habits that led to the debt in the first place. Source: Consumer NZ — Debt Solutions; CFFC — MoneyTalks (0800 345 123).

Yes, it is possible to consolidate unsecured debts such as credit cards and personal loans into your home mortgage in New Zealand, but this approach requires careful consideration. The main attraction is the much lower mortgage interest rate (currently around 6%–7% for a 1-year fixed rate) compared to credit card rates of 20%+. However, rolling consumer debt into a 25–30 year mortgage dramatically increases the total interest you pay. For example, $10,000 of credit card debt at 20% over 3 years costs about $3,300 in interest; the same amount added to a 25-year mortgage at 6.5% costs approximately $9,400 in interest over the life of the loan. You would also need sufficient home equity to top up your mortgage. Some banks allow a revolving credit facility attached to your mortgage, which can be more flexible. Seek independent financial advice from a registered financial adviser before consolidating into your mortgage. Source: MBIE — CCCFA; Financial Markets Authority NZ (fma.govt.nz).
