Supplement Margin Calculator

Your real profit per unit and per month — on any product in the catalog, at any volume, on every plan. Every fee is in the math. Nothing hidden in the fine print.

Example: Creatine Powder 300g (ROC609) at 100 units/month

MSRP $35.97. Every fee included: $2.00 fulfillment per item, 3.45% + $0.25 payment processing, membership deducted. Turn on JavaScript to run any product at any volume.

PlanProfit / unitMarginNet / month
Basic ($97/mo)$17.5148.7%$1,653.90
Launch ($157/mo)$20.1856.1%$1,860.90
Scale ($297/mo)$23.1864.4%$2,020.90

How the math works

One formula, no asterisks. For every product and plan we calculate:

Start withMSRP — the retail price you charge
MinusYour unit cost at your plan tier (lower tiers pay more per unit; Scale pays the least)
Minus$2.00 fulfillment per item — label printing and application, picking, packaging supplies and labor, shipping label
MinusProcessing fee: 3.45% of MSRP + $0.25 per order
= Per-unit profitWhat one sale actually puts in your pocket
ThenPer-unit profit × monthly units, minus your monthly membership = net monthly profit

Shipping is paid by your customer at carrier rates, so it isn’t a margin line. Catalog costs and fees come straight from our published data files — the same ones members see.

Three steps to your number

  1. Build your line-up

    Add the products you actually plan to sell — one or several. Start with a top seller or browse the full catalog; each option shows its retail price.

  2. Set each volume

    Give every product its own realistic monthly units. Start conservative — the math updates live as you drag.

  3. Compare plans

    See the combined net profit side by side on every plan, which plan wins for your exact mix, and the volume where upgrading starts paying for itself.

Common questions about the numbers

What costs apply beyond membership?

Each fulfilled order has four costs: the wholesale product cost for your plan, a $2 fulfillment fee per item, carrier shipping, and payment processing at the published rates. The membership trial waives the monthly membership fee for 30 days; it does not waive order costs. Optional branding and store services are paid separately.

How do margins work in practice?

You set your retail price (MSRPs are provided as a guide). Every order has four costs: the wholesale product cost for your plan tier, the flat $2 fulfillment fee, payment processing, and carrier shipping (usually passed to your customer at checkout). Example at Scale: Creatine 300g — $35.97 MSRP, $9.30 product cost, $2 fulfillment, ~$1.49 payment processing ≈ $23 profit per unit before shipping and ad spend, about 64% net margin.

Do unit costs drop on higher plans?

The catalog lists wholesale costs for Basic, Launch, and Scale. Scale has the lowest cost per unit. The best plan depends on your monthly volume and product mix: compare the savings against the difference in paid monthly membership. The calculator uses current catalog costs and includes the membership fee after the trial.

Who collects the customer's money?

You do — sales land in your store's payment processor like any e-commerce order. Rocktomic bills you wholesale + fees for fulfillment. Your retail price minus those costs is yours.

The margin looks good. Now make it real.
