How to Price Tools and Hardware in New Zealand: A Margin-First Method

Start From the Margin You Need

Set the target gross margin before choosing a shelf or online price. The calculation is: selling price excluding GST = product cost ÷ (1 − target gross margin). If a drill costs $40 and the required gross margin is 35%, the minimum price excluding GST is $40 ÷ 0.65 = $61.54. Gross profit is $21.54, or 35% of the selling price.

Keep fulfilment, payment fees and operating costs outside that product-cost calculation. For illustration only, $8 fulfilment, $2.50 payment fees and a $5 operating allocation leave $6.04 after those costs from the $61.54 price. That is a different measure from gross margin, and it shows whether the order contributes enough after serving the customer.

If you charge GST, convert the ex-GST price for display: $61.54 × 1.15 = $70.77. Inland Revenue states that GST in New Zealand is charged at a rate of 15%. Use the product pricing calculator to test target margins and cost inputs, then check the result against product- and collection-level profitability in ORVX (Source: Inland Revenue (Te Tari Taake)).

Build the Cost Before Setting the Price

Build the item’s cost from the supplier invoice outward, using amounts supported by purchase records. Include the product cost, supplier discounts, inbound freight, duty, customs or broker charges, and documented port or warehouse handling. Allocate shipment-level charges across the units they relate to, rather than assigning the entire freight bill to one item. Also include direct per-unit packaging or assembly costs when they are required to make the item saleable.

Use a consistent GST basis. GST in New Zealand is charged at a rate of 15% (Inland Revenue (Te Tari Taake), GST). A GST-registered store will normally compare GST-exclusive cost and selling figures; do not let recoverable GST inflate the product cost. Keep outbound delivery, payment fees, advertising and overheads visible as separate costs when assessing contribution, rather than hiding them in the item’s landed cost. The separately added worked example shows the allocation arithmetic: follow its structure, then substitute your documented invoice, freight and handling amounts. Do not add unrecorded charges or invent estimates. You can check the resulting price with the free product pricing calculator (Source: Inland Revenue (Te Tari Taake)).

Show the Price Clearly in New Zealand

Your margin calculation is an ex-GST measure; the customer-facing price is usually the NZD amount shown at the shelf or checkout. For a GST-registered store, add New Zealand’s 15% GST to the ex-GST price. Inland Revenue (Te Tari Taake) states that “GST in New Zealand is charged at a rate of 15%.” So a $100.00 ex-GST price becomes NZ$115.00 including GST. The $15.00 GST is collected for tax purposes, not gross profit (Source: Inland Revenue (Te Tari Taake)).

Use the ex-GST figure to assess margin and compare product economics. Use the GST-inclusive NZD figure when checking the price a shopper will actually see. If you start with NZ$115.00 including GST, divide by 1.15 to recover the $100.00 ex-GST amount. Label both figures in your pricing sheet so a GST-inclusive shelf price is not mistaken for revenue.

Confirm your GST status before applying the treatment. Inland Revenue (Te Tari Taake) says a business must register if turnover was at least $60,000 in the last 12 months or is expected to reach $60,000 in the next 12 months. Stores approaching that threshold should model prices and margins consistently, rather than mixing ex-GST and GST-inclusive figures.

Choose the Measure That Matches the Decision

Use the measure that matches the decision, because the same product can look healthy on markup but weak on margin after selling costs. Keep the measure consistent when comparing products, channels or price changes.

Markup is useful for converting a known cost into a quoted price, but it is not the same as margin. Gross margin is the clearest control for the product’s trading economics. Contribution margin is the decision measure when variable costs beyond the product cost affect whether a sale, campaign or price change is worthwhile.

When a Higher Price Is the Wrong Move

A higher ticket price can reduce contribution when the resulting conversion loss is larger than the margin gained per sale. Check SKU-level sessions, conversion, units sold and contribution by channel before assuming the increase worked. Separate delivered orders from cancellations and returns, then compare the same period and traffic source.

Price can also damage a bundle. If increasing one component makes the bundle’s saving harder to understand, or raises the total beyond the customer’s expected use case, attachment rate may fall. Measure bundle units, component attach rate and contribution per order, not just the standalone item’s margin.

For aged stock, a higher price may leave cash tied up while storage, handling and markdown risk continue. Review stock age, units sold, sell-through and remaining stock value before repricing. ORVX can report product and collection profitability, contribution after advertising, dead stock and return rates, and can identify where a price experiment is worth running. It cannot estimate price elasticity or predict how demand will respond, so treat the operational evidence, not a forecast, as the basis for the change.

A Pricing Review Routine for Every Range

Review each range on a fixed monthly cadence, and whenever supplier costs or freight rates change. For every SKU, refresh the current product cost, supplier discount, inbound and outbound freight, tax treatment, planned customer discount, return and refund history, and stock age. Check that the figures use the same GST basis and trading currency before comparing products.

Separate the review into three decisions. First, correct inputs: fix missing freight, outdated costs, incorrect tax treatment, duplicate discounts or returns recorded against the wrong SKU. Second, change the price only after the inputs are reliable. Use gross margin for product economics, contribution after advertising for demand-generation decisions, and inventory value or dead-stock status when aged stock needs a clearance decision. Third, monitor the result rather than assuming it worked.

• Record the old and new price, discount, delivered-order revenue, units sold, return rate and gross profit for the next review period.
• Use ORVX to compare product and collection profitability, return value and remaining stock value; its reporting counts delivered orders as revenue and excludes cancelled or returned orders.
• If the evidence is unclear, flag a price experiment rather than predicting demand. ORVX can identify where testing is worth running, but cannot estimate elasticity or forecast the response.

A defensible New Zealand price starts with the margin required, uses a complete cost base, presents tax correctly in NZD and applies the right measure to the decision. Review the inputs and the commercial outcome together rather than treating a higher ticket price as automatic progress.
