A digital marketing agency that handles Amazon advertising and the compliance rules around health products together.
Before you measure return on ads, subtract the Amazon referral fee for your health category, FBA pick-and-pack and storage, returns, and your landed cost of goods. The money left over is your contribution margin per unit. The calculator uses this number, so a sale at a 15 percent margin and a sale at a 45 percent margin are never treated as equal.
ACOS tells you how hard your Sponsored Products and Sponsored Brands ads work on the clicks they pay for. TACOS divides total ad spend by total sales, including organic orders that ads helped earn. We calculate both because a pharma brand can run a high ACOS on a launch SKU and still see healthy TACOS once repeat and subscribe-and-save orders come in.
Prescription drugs cannot be advertised or sold on Amazon, and many OTC, supplement, and device listings sit in restricted or gated categories with claim limits and approval steps. These rules change what you can bid on, which keywords are allowed, and how fast a SKU ramps. The calculator accounts for that slower, compliance-gated ramp instead of assuming a clean launch.
From your contribution margin we derive the break-even ACOS, the point where an extra ad dollar stops adding profit. We then model new-to-brand orders and repeat purchase behaviour so you can see payback over the first few months, not only first-click profit. This is what tells you whether to scale a SKU, hold it, or fix the listing first.

Most ROI tools were built for general retail and quietly assume a clean launch and a steady margin. Pharma and health products do not work that way. Listings get gated, claims get reviewed, and fees vary by category, so a campaign that looks profitable on ACOS can lose money once referral and FBA costs are counted. Dcrayons sets up the calculator with your own numbers and the category rules that apply to you, then helps you decide which SKUs deserve more spend.
We run Amazon ads and SEO across OTC, supplement, vitamin, and medical-device listings, so the calculator reflects how these categories actually behave
We work from your real fees and cost of goods, not assumed margins, so the ROI number is yours and not a template
Real questions people ask Dcrayons about amazon roi calculator (pharma). Honest answers, no jargon.
It measures profit after costs, not sales after ad spend. You enter your selling price, landed cost of goods, Amazon referral fee, FBA fees, and ad spend, and it returns contribution margin per unit, break-even ACOS, and overall return. For pharma it also accounts for the restricted categories and slower ramp that apply to health listings.
No. Prescription medicines cannot be sold or advertised through standard Amazon Seller and Advertising programs in most markets. The calculator is built for the health products you can sell, such as OTC medicines, supplements, vitamins, personal care, and many medical devices, several of which still sit in gated or restricted categories.
ACOS is ad spend divided by ad-attributed sales, so it judges your ads on the clicks they pay for. TACOS is ad spend divided by total sales, including organic orders. For supplements and OTC products with repeat and subscribe-and-save buyers, TACOS is usually the better read because it captures the organic and repeat sales your ads helped create.
Break-even ACOS is the point where one more dollar of ad spend produces exactly one dollar of profit, set by your contribution margin. Spend above it on a SKU and that SKU loses money on those ad sales. Because pharma fees and cost of goods vary widely, every SKU has its own break-even ACOS, which is why a single agency target across the catalogue is misleading.
You need your selling price, landed cost of goods per unit, the Amazon referral fee percentage for your category, FBA fees, your average return rate, and ad spend and ad sales for the period. With those, the calculator gives a realistic margin and ROI rather than a guess. Dcrayons can help pull the fee and cost figures from your Seller Central and supplier data.
We use it to decide where ad budget goes. SKUs that clear their break-even ACOS with margin to spare get more spend, SKUs that do not get a listing, pricing, or category fix first. We also use it to set realistic ACOS and TACOS targets per product instead of one number for the whole account.
