Educational

Indicative only. Why we say this

How it works

Working backwards from comfortable monthly cost.

The conventional borrowing question is "how much will I be approved for?". The more useful question for cash-flow planning is "what monthly debt-service can the business comfortably absorb, and what loan size does that map to?". The calculator runs the latter.

Slide the calculator to a comfortable monthly figure, set a sensible term, and use the resulting principal as a directional ceiling for the borrowing conversation. The lender will overlay their credit assessment on top, typically narrowing rather than expanding the figure.

What lenders actually do

DSR-based assessment, layered with security caps.

NZ lenders calculate borrowing capacity by estimating operating cash flow (typically EBITDA or net operating income), applying a debt-service-coverage requirement (commonly 1.25x to 1.5x), and working back to the principal that figure can support across the proposed term and rate.

Property-secured lending layers a loan-to-value ratio cap on top, typically 60% to 80% of the security value. The borrowing capacity is the lower of the two. New businesses with limited trading history are typically capped tighter on both dimensions.

Common SME bands

Indicative borrowing capacity by NZ SME size.

The bands below assume an established business (2+ years trading) on standard credit. Newer businesses or harder credit profiles typically access tighter limits at the upper end of the rate band.

Annual turnover Unsecured (typical) Asset-secured Property-secured
$250K $10K to $50K Up to ~$100K Up to LVR cap
$500K $25K to $100K Up to ~$250K Up to LVR cap
$1M $50K to $200K Up to ~$500K Up to LVR cap
$2.5M $100K to $500K Up to ~$1M Up to LVR cap
$5M+ Up to $1M Up to ~$3M Up to LVR cap

FAQ

Borrowing capacity calculator, NZ business questions

How much can my business borrow in New Zealand?

Indicative borrowing capacity for NZ SMEs commonly runs 10% to 25% of annual turnover on unsecured products and 50% to 100% of property value on secured products. A business with $1M annual turnover commonly accesses $100K to $250K unsecured. Property-secured limits run materially higher. The achievable amount depends on debt-service capacity, security position, and the lender's credit assessment.

What does the calculator estimate?

The calculator works backwards from a comfortable monthly repayment to the loan amount that repayment would service across a chosen term and indicative rate. It is a directional tool to set expectations, not a quote. The actual amount any specific lender will offer depends on the borrower's trading history, security, and credit profile.

What monthly repayment is "comfortable" for a NZ SME?

A common rule of thumb is that monthly debt-service should not exceed 10% to 15% of monthly turnover for unsecured borrowing, or 25% to 30% on secured. A business with $50K monthly turnover therefore commonly considers $5K to $7.5K monthly debt-service comfortable. The right level depends on margin, fixed costs, and existing debt.

Does the calculator account for existing debt?

No. The calculator runs a single-loan amortisation only. Real-world borrowing capacity is governed by the total debt-service ratio, including all existing debts. The lender's assessment is the authoritative position; this tool sets a directional floor.

How do lenders calculate maximum borrowing?

NZ lenders typically calculate borrowing capacity using a debt-service ratio (DSR) approach. The lender estimates EBITDA or operating cash flow, applies a coverage requirement (typically 1.25x to 1.5x), and works back to the principal that figure can support across the term. Property-secured borrowing layers an LVR cap on top, typically 60% to 80% of the security value.

Why does the rate matter so much for borrowing capacity?

The same monthly repayment buys very different principal amounts depending on the rate. At 8% across 5 years, a $1,000 monthly payment supports a $49,300 loan; at 18% across 5 years, the same $1,000 supports $39,400 in principal. A 10-percentage-point rate difference reduces the supported principal by around 20%.

What documents will lenders ask for?

Common NZ business loan documentation includes the NZBN, last 6 to 12 months business bank statements, P&L for 1 to 2 years (often 2 to 3 on larger or property-secured loans), cash-flow forecast where the loan funds growth, director ID, and security documents where applicable. Documentation expectations scale with loan size and security complexity.

Can I borrow more by extending the term?

Yes, mathematically. A longer term reduces the monthly repayment for the same principal, freeing capacity. The trade-off is total interest paid, which increases with term length. Borrowing capacity across a 7-year term is typically 25% to 40% higher than across 3 years for the same monthly payment, but total interest paid is materially higher.

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.
