This calculator provides an estimate only and does not include fees. It is not a quote or an offer of finance. Actual rates range from 8.99% to 29.95% p.a. (AIR) and depend on your credit profile, loan amount, term and security. Lending Room (FSP486566) is an FSPR-registered NZ finance broker, not a lender.

How it works

How are loan repayments calculated?

Personal loan repayments in NZ are worked out using three inputs. Change any one and your monthly repayment changes with it.

Loan amount (principal)

The amount you borrow. A larger loan means higher repayments, or a longer term to keep repayments manageable.

Loan term

How long you take to repay, from 6 to 84 months. A longer term lowers your monthly repayment but increases the total interest you pay.

Interest rate (p.a.)

Your annual rate, shown as AIR. A lower rate means less interest over the life of the loan. Your rate depends on your credit profile.

The amortisation formula

Most NZ personal loans use fixed monthly repayments calculated with the standard amortisation formula. Each repayment covers the interest charged that month, with the rest reducing your balance. Early in the loan more of each repayment goes to interest. Later on more goes to the principal. Our calculator applies the same formula lenders use, so the estimate reflects how a real fixed-rate loan is structured.

Why the estimate is an estimate

What affects the rate you are offered?

The calculator uses whatever rate you set. Your real rate is set by the lender once we assess your application. Rates range from 8.99% to 29.95% p.a. (AIR) and a few things move where you land in that range.

  • Your credit historyA clean file with no defaults or missed repayments gives you access to the lowest rates and the most lender options.
  • Loan amount and termThe size of the loan and how long you take to repay both feed into the rate and the total interest.
  • Secured or unsecuredA loan secured against an asset such as a vehicle usually attracts a lower rate than an unsecured loan of the same amount.
  • Income and existing commitmentsStable income and manageable existing debt help lenders offer you a better rate.

Loan repayment calculator FAQs

Common questions about the calculator and what the numbers mean.

Get My Real Rate

The calculator uses the same amortisation formula lenders use, so the monthly repayment figure is accurate for the amount, term and rate you enter. It is an estimate, not a quote. Your real repayment depends on the actual rate a lender offers you and does not include fees.

No. The calculator is a simple tool that runs in your browser. It does not access your credit file or run any check. Only when you choose to apply do we run a soft credit check, which also has no impact on your score.

The estimate covers principal and interest only. It does not include fees such as a broker fee or lender establishment fees. A broker and introducer fee of up to $1,500 (GST inclusive) may apply on successful funding, and lender establishment fees of up to $450 may also apply. All fees are disclosed before you commit.

Rates range from 8.99% to 29.95% p.a. (AIR). If you have a strong credit history you are likely to be offered a rate toward the lower end. If you are not sure, leave it near the middle for a conservative estimate. The only way to know your real rate is to apply.

Through Lending Room, personal loans range from $3,000 to $250,000 over terms of 6 to 84 months. The amount you can borrow depends on your income, existing commitments and credit profile.

Usually yes. A longer term lowers your monthly repayment but means you pay interest for longer, so the total interest is higher. A shorter term costs more each month but less overall. Use the calculator to compare terms and see the total interest for each.
