What to include in GP on Shopify

Selling price minus discounts
Cost of goods sold (COGS): product, packaging
Payment fees: Shopify Payments % + per‑order fee; any third‑party gateway add‑on %
Fulfilment costs: pick/pack, label, postage (minus any shipping the customer pays)
Refunds/returns impact: lost fees, return shipping, restock where relevant

Simple GP formula (per order)

GP = (Price − Discounts + Shipping paid by customer) − (COGS + Payment fees + Fulfilment costs)

Important:

Fees vary by market and payment method. Use the calculator to model your own rates, then verify in Admin → Settings → Payments.

What affects your GP the most

Discount depth: deeper discounts reduce net price and grow fees proportionally
COGS and postage: small changes compound over volume
Refund rate: even a few % can erase margin on thin‑margin items
Payment method mix: third‑party gateways add extra % on each order

From GP to a simple NP estimate

Net profit (NP) subtracts overheads (apps, salaries, rent, utilities, fixed ops) from GP. In the calculator you can include a rough per‑order overhead to see how close you are to true profitability.

Common actions to improve GP

Set free‑shipping thresholds to lift AOV above postage break‑even
Promote high‑margin bundles; avoid discounting low‑margin heroes
Switch to cheaper packaging that still protects the product
Negotiate carrier and supplier rates; test fulfilment options
Reduce refund drivers with accurate sizing, media and product education

Market specifics — United Kingdom

Currency: GBP (£). Try rounding retail prices to .99; keep per‑order fees at £0.25 by default.
VAT: 20% standard rate for most goods. Treat VAT as a pass‑through (not part of GP). Shipping may be VATable; check with your accountant.
Payment fees: Typical Shopify Payments snapshot is 2.0% + £0.25. Verify current rates on Shopify pricing (UK).
Gateways: If you use an external gateway, add the plan’s extra % as 3rd‑party add‑on here.
Fulfilment: Royal Mail/Evri pricing varies by size and zone; model your most common parcel to set realistic postage and pick/pack.

Example — UK numbers

Price £35 with a 10% discount, COGS £12, customer pays £3 shipping, your fulfilment costs £4 (postage + pick/pack). With 2.0% + £0.25 card fees and 3% refunds, the calculator will show your GP and a simple NP after any per‑order overhead you add.

FAQs

Does Shopify refund payment fees on returns?

Card fees are typically not refunded. Model a small refund rate to see its impact on realised gross profit.

Should I include marketing costs in GP?

No. Keep GP for product and fulfilment costs. Marketing spend belongs in your CAC/ROAS analysis and affects net profit.

What’s a healthy GP%?

It varies by category. Many DTC stores aim for 50–70% GP before overheads. Focus on improving your own baseline while staying competitive.
