How Extra Mortgage Payments Save You Money
In New Zealand, the average mortgage term is 30 years. Over that time, you can end up paying more in interest than the original loan amount. By making even small extra payments — as little as $50 per week — you can dramatically reduce both the total interest paid and the time it takes to pay off your home loan.
Switching from monthly to fortnightly payments is a popular Kiwi strategy. Because there are 26 fortnights in a year (equivalent to 13 monthly payments instead of 12), you effectively make one extra monthly payment each year without feeling the pinch.
NZ Mortgage Tips
- Check your loan agreement for any restrictions on extra repayments, especially on fixed-rate terms.
- Consider splitting your mortgage into fixed and floating portions to maintain flexibility for extra payments.
- Use any pay rises, bonuses, or tax refunds as one-off lump sum payments.
- Review your mortgage rate regularly — even a small rate reduction can save thousands.
