How to read it
Margin per unit is the money each sale keeps after paying for the product itself. Margin % is that figure as a share of the retail price, which is the number to compare across products and against the line you resell today. Total margin on the order is margin per unit multiplied by units, minus the fees charged once per order. Break-even units is how many units must sell before those once-per-order fees are covered; every unit after that is margin.
Two things change the answer most. First, the gap between unit cost and retail price: a $2 change in either moves margin per unit by the same $2, and margin % moves with it. Second, the per-order fees: on a small order they can eat the whole margin, which is why the same per-unit numbers look very different at 50 units and at 250 units. If break-even is higher than the units in the order, the order never pays for itself at these numbers — raise the retail price, negotiate the fees, or order more units.
If margin per unit is zero or negative, the retail price is at or below what you pay, and there is no break-even to show. That is not a rounding problem; it means the price or the cost has to change before the line can earn anything. Start with a sample kit to test the products on your own skin before you commit to an order size, and read the guide to reading a manufacturer quote so the unit cost you enter is the all-in figure, not just the fill price.
Not a quote. Every figure above comes from the numbers you enter, not from any manufacturer. Use the result to judge real quotes, then get itemized quotes on the same basis before committing to an order size.
Frequently asked questions
What counts as unit cost?
What you pay the manufacturer for one finished, labeled unit. If your quote bundles fill, packaging, and labels into one per-unit figure, use that all-in figure. Keep it on the same basis as the retail price: both are per unit, so a per-unit cost against a per-set retail price will mislead you.
Where do per-order fees go?
Freight, label setup, testing, or sample rounds charged once per order go in the per-order fees field. They do not change margin per unit, but they decide how many units you must sell before the order pays for itself — that is what the break-even figure answers.
What margin % should a spa aim for?
There is no single published target, and this calculator does not set one. Compare the result against what you earn reselling someone else's line and against your treatment-room margins, and judge it against your own costs — rent, staff time, and the shelf space the line occupies. The calculator shows your number so the comparison is honest.
Is this a quote from a manufacturer?
No. Every figure comes from the numbers you enter. Nothing here is a price from any manufacturer. Use the result to judge real quotes: get every quote itemized on the same basis — same products, units, and packaging — or the totals will mislead you.
