What Goes Into the Delivery Cost

Use an all-in delivery-cost measure rather than the carrier label alone. For each order, add the carrier charge, packaging, pick-and-pack labor, shipping software allocation and any invoice adjustments. For example: $8.40 carrier charge + $0.85 packaging + $2.10 labor + $0.20 software allocation = $11.55 before adjustments.

The carrier line includes the selected service and any surcharges shown on the invoice. Packaging includes the mailer, box, tissue, tape and label. Labor is the time spent picking, packing and handing over the parcel, multiplied by the applicable hourly cost. Allocate shipping software by shipment, label or order, whichever matches the plan.

Keep adjustments separate so they remain actionable. Address corrections, residential or delivery-area surcharges, insurance, credits and carrier invoice corrections can materially change the final amount. The label price is the right measure for comparing services at checkout; all-in delivery cost is the right measure for setting charges and checking margin after fulfilment. Exclude the garment’s product cost and general marketing spend from both measures.

How Weight and Size Affect Fashion Parcels

Carriers price a fashion parcel using its actual weight, dimensional weight, or whichever produces the higher billable weight. Actual weight is what the packed order weighs on a scale. Dimensional weight reflects the space it occupies, calculated from the parcel’s length, width and height using the carrier’s divisor. A lightweight coat in a large box can therefore cost more than its scale weight suggests. Measure the parcel after adding the mailer, box, tissue and other packaging.

The shipping zone reflects the distance between the dispatch point and the customer’s address. The same parcel can cost different amounts across the US. Service speed is a separate input: expedited delivery generally carries a higher charge than a slower service. Use actual weight to review product and packing weight, dimensional weight to reduce empty space, zones to assess fulfilment-location effects, and service speed to check whether a delivery promise supports its charge.

Worked example with sample numbers

This example uses sample numbers for a women's fashion store selling in the US. They are made up to show the method, they are not a benchmark, and your own figures will differ.

Formula: Lowest safe basket = (delivery + packing + fixed fee) / (gross margin rate - percentage fee - minimum margin you will accept).

Three Ways to Recover Delivery Costs

Charge delivery at checkout when preserving product margin matters more than hiding the cost. If an order costs $8 to deliver, charging the customer $8 keeps that expense out of the item economics. This suits lower-value or single-item orders, but makes the delivery fee visible at the point of purchase and may affect conversion or basket composition.

Absorb delivery into the product margin when a simpler, delivery-included offer supports the way customers shop your collection. For illustration only, a $60 product with an $8 delivery cost has $52 left before other costs if the customer pays nothing for shipping. This approach can work when the resulting price remains commercially viable, but it transfers delivery risk to every order, including small baskets and remote destinations.

Combine both measures when you want smaller orders to contribute toward delivery while giving customers a reason to add another item: charge below a stated basket value and waive the charge above it. This can protect contribution on low-value orders without treating every order alike. Compare the methods using realized revenue, gross profit and margin, not revenue alone. ORVX shows product- and collection-level profitability so you can see which approach fits each part of the range.

Choosing Between Flat Rate and Free Delivery

A flat rate gives clearer cost control when delivery costs are reasonably consistent across your typical women's fashion orders. If your all-in delivery cost averages $9 and you charge a $7 flat rate, you know each order contributes $2 toward delivery while keeping the checkout offer straightforward. Review the rate when your order mix changes: a flat fee that works for single-item orders may underrecover costs on larger, heavier parcels.

Free delivery simplifies the offer by removing a separate checkout charge. It can make product prices and campaign messaging easier to present, but the store still pays to deliver every qualifying order. For illustration only, absorbing an $8 delivery cost on 100 orders adds $800 to fulfillment expense. That cost needs to fit within the margin left after product cost, discounts, returns and advertising.

Choose the measure that matches the decision. Use a flat rate when protecting contribution and forecasting delivery recovery are the priority. Use free delivery when a simpler offer is more valuable and your product margins can absorb the variation in delivery cost. Check both approaches against product- and collection-level profitability, rather than judging them by conversion or revenue alone.

How to Set and Test a Shipping Threshold

Choose a threshold from your order economics, not a competitor’s offer. Use the profit margin calculator to model the incremental basket. For illustration only, if a $68 order includes $6 paid shipping and costs $9 to deliver, the current delivery subsidy is $3. A $85 free-shipping threshold gives up $6 of shipping revenue. If the extra $17 of merchandise produces $12 in gross profit, the larger order adds $6 before other variable costs. Set the threshold only where that trade-off remains acceptable across common basket sizes.

Test the current policy against the threshold over comparable periods, keeping promotions, traffic mix and seasonality as consistent as possible. Track conversion rate, average order value, delivery cost per delivered order and contribution margin per order. Also compare return rate and the share of orders reaching the threshold. A higher average order value is not a win if conversion falls or delivery concessions reduce contribution. Exclude cancelled and returned orders from realized-revenue comparisons; ORVX calculates realized revenue from delivered orders only. Review results by product or collection when mix changes, since a threshold can help low-cost baskets and hurt bulky or low-margin ones.

How to Read the Worked Example

Read the worked example from left to right. The parcel-cost line is the store’s actual delivery expense for the order, before considering what the customer pays. The customer-charge line shows how much of that expense is recovered at checkout. Subtract the charge from the parcel cost to see the delivery amount the store absorbs; a negative result means the charge exceeds the cost and contributes toward order profit.

Next, follow the margin impact rather than stopping at the shipping line. The calculation shows how the absorbed amount reduces contribution and net margin after product cost and other included costs are accounted for. Finally, read the threshold decision as a test of incremental economics: qualifying for delivery treatment should produce enough additional product margin or basket value to cover any extra delivery subsidy. The decision is not whether the threshold sounds attractive; it is whether the order remains profitable after the customer charge, delivery cost and added basket economics are all included. Use the same sequence when comparing different charges or thresholds.

For a women’s fashion store, the workable shipping policy is the one that connects the customer-facing offer to the real cost of each parcel. Review weight, dimensions, destination and handling costs first, then compare paid delivery, free delivery and a threshold against contribution margin. Recheck the policy when packaging, carrier rates, product mix or order values change.
