Warning - personal loans can create long-term debt that's hard to repay if you're financial situation changes for the worst. Please consider all options before accepting a personal loan offer, and always obtain multiple quotes from lenders to ensure you're fully comparing the market. Different lenders have different criteria, meaning the interest cost varies widely.

Know this: Missing a payment on a personal loan will have severe consequences on your credit history and will likely make borrowing in the future far more difficult

If you have security over your loan, if you do not keep up with repayments, your security will be repossessed - this could mean losing your car, boat or another asset.

Personal loans and you

Many New Zealanders apply for personal loans to pay for a large purchase, usually a car, home improvements, a wedding or even a holiday.
Unless you have a decent level of savings, a personal loan is the only way to get the financing in place to buy what you want.
But be aware that personal loans often can be costly, and you will need to know exactly what you're signing up for.

Loan limits and repayments

Personal loans usually have a maximum amount you can borrow, typically around $20,000. Some lenders require security, others do not - generally, interest rates will be lower if you can provide security. But if you later default on the loan, you could lose your property.
Most loan terms run from one year up to five years - the longer your loan, the more interest costs you will pay overall so having a shorter term is better for you financially.
Interest rates are usually fixed which means what you pay will always be the same throughout the term of the loan.

What is the maximum limit for a personal loan?

It really depends on what the loan is for, rather than the maximum you can borrow.
As such, spending no more than 10% of your monthly pre-tax income on a personal loan is a smart way to avoid financial worries.
For example, if you earn $50,000 a year, that's around $420 per month. This leaves you money for essential living expenses while you repay your loan.
