Net dropshipping margin = Selling Price − Product Cost − Shipping − Ads − Platform Fees. Aim for ≥25%.
Most successful dropshippers target 25–40% net margin before scaling.
Ad costs are the #1 profit killer — always calculate CPA before scaling.
Reach for this calculator when you need to present a business metric to stakeholders. Accurate, consistently-defined figures command more credibility than estimates, particularly in financial discussions.
A common mistake is comparing metrics that use different definitions — gross margin versus net margin, revenue versus profit, customer count versus paying customer count. Always confirm the definition of each input before comparing results across periods or sources.
A startup founder uses the calculator to determine break-even point: fixed monthly costs £12,000, variable cost per unit £18, selling price £42. Break-even is 500 units per month — a concrete sales target that the team can evaluate against pipeline and capacity.
25–40% net margin is considered healthy for dropshipping. Below 15% is very difficult to scale profitably.
Break-even CPA = Selling Price − Product Cost − Shipping − Processing Fee. Any ad spend above this loses money.
