Free Personal Loan Calculator for New Zealanders
NZ personal loans are typically unsecured at 11-19%, with terms from 6 months to 7 years. Repayments use the same amortisation maths as a mortgage. The calculator returns per-period repayments, total interest, and the all-in cost.

Based on a $15,000 personal loan at 14.95% over 3 years.
About our Personal Loan Calculator
$15,000 borrowed at 14% over 4 years costs $4,683 of interest plus around $500 of fees. The same loan at 11% (a typical NZ bank rate for a strong-credit customer) costs $3,604 of interest plus the same fees. The 3% rate gap, applied to a 4-year term, saves $1,079, which is roughly the cost of replacing the kitchen sink with a slightly nicer one.
The calculator runs the same amortising-loan maths used by NZ banks and non-bank consumer-finance providers. Move the rate slider to bracket your offer against typical NZ pricing. Move the term slider to see the cash-flow trade-off between lower per-period repayments (longer term, more total interest) and faster payoff (shorter term, less interest, higher per-period bill).
Pricing in NZ’s personal-loan market splits roughly into three tiers. Bank loans for prime-credit customers sit at 11-13%. Bank loans for mid-credit customers sit at 13-16%. Non-bank consumer-finance and "instant approval" lenders sit at 17-19%, sometimes higher.
How to use it
Enter the loan amount, the offered rate, and the loan term in years.
For the rate, the headline figure on the lender’s website is your starting point. The actual offer depends on credit score and personal circumstances; the lender will give a binding rate after they pull your credit file. Always ask for the comparison rate (which includes fees) when comparing offers across lenders.
The result panel returns the per-period repayment, total amount repaid over the term, and total interest. Add typical fees of $400-$800 over a 4-year loan to get the all-in cost.
Why use it
The single biggest mistake on personal loans is comparing headline rates rather than comparison rates. A 12.95% headline rate with $50/month admin fees costs more over 4 years than a 13.95% rate with no admin fees, despite looking 1 percentage point cheaper at the top.
The same calculator answers the term question. A $20,000 loan at 14% over 5 years costs $7,940 in interest. The same loan over 3 years costs $4,584. The decision is between $466 a month for 36 months and $311 a month for 60 months, with the 5-year option costing $3,356 more in total interest. Whether the cash-flow saving justifies the extra cost is a personal call.
For debt consolidation (combining credit-card debt at 20%+ into a personal loan at 14%), the calculator surfaces the saving on the consolidated loan, which can be substantial. The debt-consolidation calculator handles the full comparison including any establishment fees on the new loan.
The maths behind it
M = P × r × (1+r)n ÷ ((1+r)n − 1) Standard amortising-loan formula. P is the loan amount. r is the periodic rate (annual rate divided by payments per year). n is the total number of payments. M is the per-period repayment. Personal loans typically run 6 months to 7 years, with monthly, fortnightly, or weekly repayments. Total cost is M × n; total interest is M × n − P. Establishment and ongoing fees are layered on top of interest and add typically 2-5% to the all-in cost.
Worked example
Eve, sole trader baker in Greymouth, taking a $15,000 personal loan at 14% over 4 years for a kitchen renovation.
Eve runs a wholesale bakery from a leased commercial kitchen in Greymouth. She wants to buy a $15,000 commercial-grade dough mixer, financed through her bank as an unsecured personal loan.
At 14% over 4 years (48 monthly payments), the monthly repayment is $410. Total paid back: $19,683. Total interest: $4,683.
On top of interest, the bank charges a $250 establishment fee and $5/month admin fee. Over the 4-year term, fees add another $490. Eve’s all-in cost lands at $20,173, or $5,173 of finance cost on $15,000 borrowed.
Switching to a 3-year term at the same rate raises the monthly to $513 but cuts total interest to $3,461 (a $1,222 saving) before fees. Eve’s decision is whether the extra $103 a month over 3 years is more affordable than the longer 4-year stretch.
Things to keep in mind
- Unsecured loans cost more. Personal loans are typically unsecured (no collateral), which is why rates run 11-19% versus 8-12% for secured car loans or 5-7% for mortgages. The rate gap reflects the lender’s higher risk if the borrower defaults; without collateral the lender can only chase the debt through standard credit recovery channels.
- Fees can be significant. NZ personal loans typically charge $200-$400 establishment, $5-$10/month admin, and sometimes a $50-$100 final-payment fee. On a 4-year $15,000 loan, fees alone can add $400-$800 to the all-in cost. The calculator shows interest only; ask the lender for the all-in CCCFA-disclosed total before signing.
- Comparison rate beats headline rate. The CCCFA requires lenders to disclose a "comparison rate" that includes fees. Compare the comparison rate (not just the headline rate) when shopping between lenders. Two loans with identical headline rates can have meaningfully different comparison rates if their fee structures differ.
- Early repayment is usually free. Most NZ personal loans allow extra payments and full early payoff without penalty. Some non-bank lenders charge a small early-repayment fee on the unpaid interest; the CCCFA disclosure document spells out the specific terms.
- Debt consolidation can pay off, but watch the trap. Consolidating high-rate credit card debt (often 20%+) into a personal loan at 14% saves interest. The trap is going back to spending on the credit card after the consolidation, ending up with both. The debt-consolidation calculator handles the comparison.
NZ-specific notes
FAQs
What rate should I expect on a NZ personal loan?
Bank-issued unsecured personal loans typically sit at 11-15% in mid-2026. Credit unions can run 1-2 percentage points lower. Non-bank consumer-finance providers can run 17-19% or higher. The actual rate depends on credit score, loan amount, and term; smaller and shorter loans often price higher than larger, longer ones.
How is a personal loan different from a car loan?
A car loan is usually secured against the vehicle, which lowers the rate. A personal loan is unsecured, which means a higher rate but no asset at risk. For buying a vehicle, a secured car loan is usually cheaper than a personal loan; for renovations, holidays, or debt consolidation, the personal loan is the standard option.
Can I pay off the loan early?
Yes, most NZ personal loans allow full early payoff at any time. Some lenders charge a small early-repayment fee covering admin or unrecouped early-payment interest; the CCCFA disclosure document spells this out. Before-rate-cycle payoffs are usually fee-free with bank loans.
What does "comparison rate" mean?
The comparison rate is the all-in rate including establishment and ongoing fees, expressed as an equivalent annual rate. It lets you compare two loans on a fair basis. Compare comparison rates rather than headline rates when shopping; lenders sometimes advertise a low headline rate alongside high fees that push the comparison rate well above competitors.
Can I get a personal loan with a poor credit history?
Yes, but at higher rates. Mainstream banks may decline; non-bank consumer-finance providers (often advertising "approval for everyone") will lend at 19-25%, sometimes higher. The Commerce Commission’s responsible-lending rules still apply, so the lender has to check affordability.
What about Buy-Now-Pay-Later vs personal loans?
BNPL services (Afterpay, Laybuy, Zip) are typically interest-free over 6-12 weeks but charge late fees if a payment is missed. They suit small amounts ($100-$2,000) over short windows. For larger amounts ($5,000+) over longer terms, a personal loan is usually cheaper despite the headline interest rate, because BNPL late fees can compound quickly.
How does the calculator handle weekly vs monthly repayments?
It computes whichever frequency you select. Weekly and fortnightly schedules result in slightly less total interest than monthly because each payment chips at the principal sooner. The difference over a 4-year term is usually $50-$150 of saved interest, small relative to the loan size.
