How to pay off debt in New Zealand: avalanche or snowball?

Last reviewed

Step 1: List what you owe

Write down each debt with its balance, interest rate and minimum repayments. Your statements and loan contracts show the rate. For example:

Debt Balance Interest rate Minimum a month
Credit card $6,000 22% $180
Car loan $9,000 8% $280
Personal loan $2,000 10% $90

That’s $550 a month of minimums. Say you can pay $200 more, $750 a month in all.

Don’t forget buy now, pay later plans, overdrafts and money owed to Inland Revenue or Work and Income.

Step 2: Pick a method

Both methods pay the minimum on everything and put the extra on one debt. When it’s paid off, its payment rolls onto the next.

  • Avalanche: the highest interest rate first (here, the credit card). It costs the least.
  • Snowball: the smallest balance first (here, the personal loan). You clear a debt sooner, which keeps many people going.
Three ways to clear the same debts $17,000 of debt, paying $750 a month ($550 of minimums plus $200)
Avalanche Highest rate first · first debt gone after 19 months
Debt-free 26 months Interest $2,367
Snowball Smallest balance first · first debt gone after 8 months
Debt-free 27 months Interest $2,580
Minimums only Nothing extra · first debt gone after 25 months
Debt-free 52 months Interest $4,741

Worked out month by month, as in our debt payoff calculator.

The difference between the two methods is small here. What matters most is paying more than the minimums, and keeping at it. Try your own debts in the debt payoff calculator.

Step 3: Pay less interest

  • A balance transfer card moves card debt to a card with a low rate for a set time, usually 0% for about 6 months in New Zealand. The rate then jumps, so pay it off before then.
  • A consolidation loan from your bank or a credit union can replace several repayments with one. Standard credit cards often charge around 20% to 21% a year, and bank personal loans around 12% to 14% for people with good credit. It only helps if you don’t run the cards up again.
  • Ask for hardship help: under the CCCFA, you can ask your lender to change your repayments if illness, losing your job or another reasonable cause means you can’t keep up.

Step 4: Find more to pay

  • Make a budget and give the extra a fixed amount each week or month. The budget calculator shows where your money goes.
  • Put windfalls on the debt: tax refunds, bonuses and gifts.
  • Stop adding to it: take the card out of your phone’s wallet, and pay by debit card while you clear it.
  • Check the help you can get, such as Working for Families or the Accommodation Supplement: see help you might be missing.

Step 5: Stay out of debt

Once a debt is gone, keep paying the same amount into savings. An emergency fund means the next surprise bill doesn’t go back on a card. Paying on time also builds your credit history: see credit scores explained.

Frequently asked questions

Which is better, the avalanche or the snowball?

The avalanche, highest rate first, saves the most interest. The snowball, smallest balance first, clears a whole debt sooner, which keeps many people going. In our example the gap is about $200 of interest, so pick the one you’ll stick to.

How much does paying only the minimums cost?

In our example of $17,000 of debts, paying only the minimums takes about twice as long and costs about twice the interest as adding $200 a month and using the avalanche.

Should I consolidate my debts into one loan?

It can help if the new loan has a lower rate than your cards and you don’t run the cards up again. Compare the total cost, including any fees, not just the repayment.

Is a balance transfer worth it?

Balance transfer offers in New Zealand are usually 0% for about 6 months, or a low rate for longer. It pays off if you clear as much as you can during the offer and stop using the old card.

What if I can’t afford my minimum repayments?

Ask your lender for a hardship change straight away, and call MoneyTalks on 0800 345 123 for free help from a financial mentor. Don’t borrow more to cover repayments.
