Helium 10 Profitability Calculator: Review & Tutorial

In this guide
The quick answer
What is the Helium 10 Profitability Calculator?
The Helium 10 Profitability Calculator estimates profit per unit, profit margin, and ROI for an Amazon product. Open it through the Helium 10 Chrome extension, check the listing data, and enter your own costs. It helps you compare potential products and fulfillment options before committing to inventory.
A product selling for $25 can look attractive beside a $5 supplier quote. But that gap still has to pay for delivery, Amazon fees, advertising, and the less obvious costs of running the business. I want you to see what remains before placing an order.
In the video below, Carrie Miller from Helium 10 joins me for a calculator walkthrough using a garlic press. We cover pricing, dimensions, freight, storage, duties, other costs, and FBM. This guide follows those topics and adds a separate worked example you can adapt.

Install the extension, sign in to your Helium 10 account, and open a comparable product on a supported Amazon marketplace. Select the Helium 10 icon in Chrome, then open Profitability Calculator. Pinning the extension makes it easier to find next time.
Helium 10’s official access guide also describes opening it through the product summary: choose Show Full Details, then Estimate Net/Margin. Access includes free plans with limitations, and marketplace support affects availability.
Choose a comparison product with a similar pack quantity and physical format. A single garlic press and a gift set with three accessories need different assumptions, even if both appear for the same search term.

Which costs should you enter?
Treat the calculator’s prefilled information as a starting point. It can use data from the listing you opened, but that listing cannot tell you your supplier terms or your shipping quote. Helium 10’s calculator overview explains the editable inputs.
| Input | What I would check |
|---|---|
| Selling price | Use a price you can justify against comparable offers, including your likely discount strategy. |
| Dimensions and weight | Measure the packaged unit you will actually sell. Check units of measurement and pack quantity. |
| Manufacturing cost | Use a written quote for your specification and order quantity; confirm whether packaging is included. |
| Freight | Allocate the shipment quote to units using an appropriate basis. Confirm which delivery stages it covers. |
| Duties and import costs | Use a current, product-specific estimate from your broker or forwarder. Identify costs already included in freight. |
| Storage time | Test a realistic selling period and a slower scenario. Include any separate warehouse charges. |
| Amazon fees | Check fulfillment and referral charges separately against your marketplace and product details. |
| Advertising and other costs | Allow for marketing, preparation, expected returns, and overhead that your model has not already counted. |
Keep a note beside every estimate: where it came from, when you received it, and what it includes. A $1.20 freight allowance is much more useful when you know whether it covers port delivery, final delivery, or both.
Count each cost once. If your supplier quote includes retail packaging, do not add the same packaging charge again. If an import-inclusive shipping quote already covers a charge, reconcile that amount before entering a separate allowance.
I would ask for the final packaging measurements before approving production. A small change in a box can matter across thousands of units. Test proposed packaging in the model, then confirm it still protects the product properly.
FBA fees, referral fees, and storage are different charges
The FBA fulfillment fee relates to Amazon fulfilling orders. The referral fee is a selling fee that varies by category and, in some cases, price. It also applies to merchant-fulfilled sales. Check Amazon’s current selling-fee information instead of applying one percentage to every product.
Storage is another cost. Amazon describes monthly storage charges based on the space inventory occupies. Review its FBA cost overview for additional charges that may apply. A basic calculator estimate should not be assumed to include every account-specific expense.
If Xray shows a different number, compare the labels first. Helium 10 explains that Xray’s Fees column combines fulfillment and referral fees, while the calculator shows the FBA fee separately. Comparing those two lines directly can create a false discrepancy.
Use the current fee estimate for your product and marketplace. The dollar amounts shown in an older tutorial are examples from that recording, rather than a fee schedule for a new shipment.
A worked example: what remains from a $25 sale?
Here is a separate teaching example, not Carrie’s live result or a current Amazon quote. All figures are hypothetical US dollars per unit. The 15% referral assumption and the $4.50 fulfillment assumption must be replaced with the rates that apply to your product.
| Item | Per unit |
|---|---|
| Selling price | $25.00 |
| Manufacturing and packaging | $5.00 |
| Freight | $1.00 |
| Import and preparation allowance | $0.50 |
| FBA fulfillment assumption | $4.50 |
| Referral fee assumption: 15% | $3.75 |
| Storage allowance | $0.35 |
| Advertising assumption: 12% of total sales | $3.00 |
| Returns and overhead allowance | $0.90 |
| Total modeled costs | $19.00 |
| Estimated profit per unit | $6.00 |
| Estimated profit margin | 24% |
The calculation is $25 − $19 = $6. Divide that $6 by the $25 selling price, then multiply by 100: the modeled margin is 24%. This is the result after the listed allowances, but before any costs or taxes omitted from the example.
Now reduce the selling price to $22. Holding the dollar-based costs constant, the assumed referral fee becomes $3.30 and advertising becomes $2.64. Profit falls to $3.81 per unit, or about 17.3%.
That $3 price reduction removes $2.19 of profit. To earn the same $600 contribution as 100 units at the original price, you would need to sell about 158 units at the lower price, assuming the model still holds. A discount needs a plausible sales benefit to justify that tradeoff.
Margin and ROI use different denominators. Margin compares profit with revenue. ROI compares profit with the investment basis used in the calculation. For example, $5 profit on $25 revenue is a 20% margin; $5 profit against a defined $10 investment is a 50% return. Check which costs the calculator includes in its ROI basis before comparing tools.
Add advertising without confusing TACoS and ACoS
TACoS, or total advertising cost of sale, compares advertising spend with total sales revenue, including organic sales. ACoS compares advertising spend with ad-attributed sales. Use the denominator that matches your forecast.
For example, $1,200 in advertising against $10,000 in total sales gives a 12% TACoS. If $4,000 of those sales were attributed to ads, ACoS would be 30%. Entering 30% as the share of all revenue spent on advertising would describe a different budget.
In our $25 example, raising advertising from 12% to 20% adds $2 per unit. Estimated profit falls from $6 to $4, and margin falls from 24% to 16%. The product has not changed, but the amount available to pay you has.
I would test several advertising assumptions before choosing a product. Once it launches, replace the forecast with observed spending and sales for matching periods. A launch target is an assumption to validate, not evidence that the product can maintain it.
Test the assumptions that could change your decision
Save a base case, then change one input at a time. This makes it easier to see which uncertainty deserves another supplier conversation or a better quote. Open the scenarios below to work through the example.
What if fulfillment costs $1 more per unit?
At the original $25 price, estimated profit falls from $6 to $5 and margin becomes 20%. Across 1,000 units, that difference is $1,000. Confirm the packaged dimensions and fee estimate before treating the cheaper scenario as your plan.
What if lower prices and higher advertising happen together?
At $22 with advertising at 20%, a 15% referral assumption, and the original fixed-dollar costs, profit is $2.05. If fulfillment also rises by $1, profit becomes just $1.05, about 4.8% of revenue. Combined changes can expose a weakness that separate tests hide.
What is the break-even price in this example?
The fixed-dollar costs total $12.25 per unit. With referral fees at 15% and advertising at 12% of revenue, 73% of each sales dollar remains to cover them. Dividing $12.25 by 0.73 gives a modeled break-even price of about $16.78. This only holds while those assumptions remain unchanged.
Also test slower inventory turnover. A product can show an attractive return per unit while keeping your cash tied up for months. Put the expected order date, arrival date, and selling period beside the margin estimate so you can judge the timing as well as the percentage.

The tutorial also demonstrates an FBM calculation. With Fulfilled by Merchant, you or your logistics provider handle fulfillment. Build a complete alternative using your actual carrier, storage, packing, and handling costs.
For a useful comparison, keep the product and cost assumptions consistent. Suppose your FBM carrier label costs $4, packaging costs $0.60, and handling costs $1.20. That is $5.80 before any separately billed storage or returns handling. Comparing only the $4 label with an FBA fee would leave out part of the work.
Ask a warehouse for its full rate sheet, including minimum charges and charges for receiving stock. If you fulfill orders yourself, assign a realistic cost to your time. Check whether the service can meet the delivery promise you intend to offer.
Amazon’s Revenue Calculator, linked from its selling-fee page, provides another way to compare fulfillment estimates. Align the inputs before interpreting a difference between tools.
My review: useful for testing a product’s economics
The strongest reason to use this calculator is the ability to challenge an idea while you are still researching it. You can change a price or cost assumption and see whether the potential reward still makes sense. I would use that flexibility before negotiating an order quantity.
Where it helps
Comparing cost assumptions, checking the room available for advertising, and spotting the expenses that have the greatest effect on the result.
What still needs validation
Customer demand, the price buyers will accept, supplier reliability, and the accuracy of your quotes. A positive estimate does not establish those facts.
My suggested next step is simple: choose one candidate, record your base case, and list the three least certain inputs. Resolve those uncertainties before expanding the spreadsheet to dozens of products. A smaller shortlist with stronger evidence is easier to act on.
Helium 10 Profitability Calculator: common questions
Is the Profitability Calculator free?
Helium 10 lists access on free plans with limitations. Check your account’s current allowance and supported marketplace. My free account guide explains the starting options.
Does it calculate my final business profit?
It estimates the result from the inputs and costs included. Reconcile actual sales, expenses, refunds, and other business costs separately. A research estimate is not a completed profit-and-loss statement.
What profit margin should I target?
Set a target that leaves room for the costs and uncertainty in your business. Compare the base case with your weaker scenarios. A percentage that looks attractive before advertising or returns may look very different once those costs are included.
Why is the calculator missing from an Amazon page?
Check that the extension is installed and signed in, and that the marketplace is supported. Confirm your current usage allowance. If the issue persists, use Helium 10’s access guide linked above or contact its support team.
