Indicative only. Why we say this

What it means

The weekly cost is what most NZ businesses budget on.

Weekly is the natural cash-flow rhythm for most NZ small businesses. Hospitality, retail, trades, transport, and most service businesses see money arrive every week (or every day, summed weekly) rather than in monthly tranches. A loan repayment that matches the inbound rhythm is easier to plan against and easier to absorb when a quiet week lands.

Most NZ business lenders run weekly repayment as the default on small-business term loans for exactly this reason. Monthly is more common on commercial property loans, large equipment loans, and bank-branded products where the borrower is on a monthly billing cycle.

When weekly suits

Weekly often beats monthly on total interest.

Repaying weekly versus monthly on the same nominal annual rate produces a slightly lower total interest figure, because principal pays down faster. The difference is small on short loans (under 2 years) and material on longer ones (4 to 5 years). On a $100,000 5-year loan at 12%, weekly repayment typically saves around $400 to $700 in total interest against monthly.

The savings are real but secondary. The bigger reason to prefer weekly is the cash-flow alignment, not the interest savings.

FAQ

Weekly repayment calculator, NZ business questions

How does a weekly repayment calculator work?

The calculator takes the loan amount, the loan term in months, and an indicative annual interest rate, then runs the standard amortising-loan formula to produce the equivalent weekly repayment. Behind the scenes, the monthly amortising payment is calculated, then divided into 52 weeks per year to convert to a weekly figure. The result is indicative; the actual rate and repayment a lender offers depends on the lender's assessment.

Why pay weekly instead of monthly on a NZ business loan?

Weekly repayments suit businesses with weekly inbound cash flow (most retail, hospitality, trades, and service businesses) because the loan repayment matches the rhythm of the business. Weekly also reduces total interest slightly versus monthly, because principal pays down faster across the year. Monthly suits businesses on monthly billing cycles where the cash arrives in one or two payments a month rather than continuously.

Is the weekly repayment fixed for the life of the loan?

On a fixed-rate amortising NZ business loan, the weekly repayment is fixed for the life of the loan. On variable-rate products like a line of credit or overdraft, the repayment can move as the lender's base rate moves. Most NZ small-business term loans are fixed, so the weekly cost is predictable from settlement.

What's a typical weekly repayment on a $100,000 NZ business loan?

On a $100,000 secured business loan at an indicative 9% per annum across a 5-year term, weekly repayment lands at around $479. On the same amount at 14% unsecured, the weekly lands at around $537. The difference of around $58 a week multiplies to roughly $15,000 across the 5-year term, which is why security and rate matter materially.

How can I reduce my weekly repayment without extending the term?

The strongest levers are reducing the loan amount (a deposit lowers principal), securing the loan (security typically drops the rate by several percentage points), or shopping the rate across multiple lenders before signing. Extending the term reduces the weekly cost but increases total interest paid across the loan, which is a separate trade-off.

Can I make extra weekly repayments to pay down the loan faster?

Most NZ small-business unsecured term loans allow unlimited extra repayments at no cost. Some structures charge a break fee on early settlement; the loan contract is the authoritative reference. Extra repayments materially reduce total interest paid because each extra dollar reduces the principal that interest is charged on.

Disclaimer

Indicative content only. Not personalised financial advice.

A business loan is a commitment that runs for months or years, and repayments come out of the same operating cash flow as everything else. Before committing, it is worth modelling the weekly and monthly cost against the business's working-capital position, which is what this site is built to help with. Borrowing at a level that stays comfortable through a quiet quarter, not just a strong one, is widely regarded as the safer frame.
