The Hidden Cost of Free Shipping in WooCommerce
Free shipping is attractive because it removes a visible charge at checkout. But the charge does not disappear: somebody still pays the carrier, packaging and handling costs. For a WooCommerce store, the question is not simply whether free shipping increases conversions. It is whether the orders it creates still generate a healthy contribution after costs.
Calculate the real cost of an order
Start with revenue excluding any tax that you collect on behalf of the authorities. Subtract the cost of goods, payment processing charges, packaging, the actual cost of shipping, and other variable fulfillment costs. For example, a hypothetical order worth $80 might have $45 in product costs, $2.50 in payment fees, $3 in packaging and $9 in shipping. Its contribution before advertising, fixed overhead and returns would be $20.50. Calling that $80 ârevenue earnedâ tells you very little about its profitability.
Test the threshold rather than guessing
A free-shipping threshold can encourage customers to add another item. But compare the incremental margin from that item with the delivery subsidy. If a basket rises from $65 to $85 because of a $20 add-on with only $4 of margin, offering $9 shipping free may still hurt. Conversely, an add-on with a healthier contribution could justify the promotion.
Check average order value, margin by product category, package weights and the distribution of orders around the proposed threshold. Heavy and oversized items may need separate rules. A flat threshold that works for accessories may not work for bulky products.
Monitor the result
Compare periods with similar traffic and promotions. Track order contribution, not only conversion rate and gross sales. Include refunds and failed deliveries when reviewing outcomes. If the store grows while per-order profitability collapses, the shipping offer may be too generous.
For a practical look at costs and margins, explore Pluginivo Order Profit Calculator for WooCommerce and its documentation. It helps store owners organize profitability analysis; your actual shipping and fee inputs still determine the quality of the result.
Build a realistic shipping test
Set up three cart examples: a small order below your threshold, one just above it, and one containing a heavy item. Record merchandise revenue excluding collected taxes, the actual carrier charge, packaging, transaction fees and cost of goods. Calculate contribution for each order, then compare the result with the same baskets when shipping is paid by the customer. This makes the trade-off visible before changing the store-wide rule.
Test your shipping policy with a controlled period rather than judging one busy weekend. Segment results by country and parcel weight, because the same threshold can produce very different contributions across destinations. If you use discount codes, measure the combined impact of the discount and subsidized delivery.
