Amazon Revenue Calculator: FBA vs Self-Shipping Profit

The Amazon revenue calculator is a free tool that compares your monthly profit from FBA with your profit from shipping orders yourself. It subtracts referral fees, selling plan fees, fulfillment costs, ads and product costs from your sales for each method, then names the more profitable one. Referral and plan fees apply to both methods, so the choice usually comes down to fulfillment and storage costs.

It also shows the profit gap per unit. Every result is an estimate, not a promise.

What Is an Amazon Revenue Calculator?

An Amazon revenue calculator estimates what a product earns after fees and costs. It multiplies your price by the units you sell, then subtracts Amazon’s fees, advertising, product costs and fulfillment costs.

The cheapest fulfillment method is not always the obvious one, so this calculator runs both side by side. A light, small product may favor FBA, while a bulky one may not.

Who Should Use the Amazon Revenue Calculator?

People use it for different planning goals.

• New sellers can choose a fulfillment method before launch.
• Current FBA sellers can test whether self-shipping would save money, which is often the case for lighter products.
• Product researchers can compare several ideas on the same basis and screen out the ones with thin margins.
• Small brands can plan margins before they negotiate with suppliers.

How to Use the Amazon Revenue Calculator Step by Step

Using the Amazon revenue calculator takes three steps: enter your numbers, compare the two results, then check the table to see how each figure is worked out.

Step 1: Enter your product, sales and fee details

Start with your selling price, product cost and monthly units sold. Add your ad spend, referral fee and Amazon selling plan, then the FBA fee, storage fees and your self-ship cost per unit.

Step 2: Compare FBA and self-shipping profit

The large number shows your estimated monthly profit for the chosen method. Below it, the tool compares FBA profit with self-ship profit and names the better option. For instance, FBA earns about $2,255 and self-shipping earns about $1,985 a month.

Step 3: Check the breakdown table

The breakdown table shows how each figure is worked out. For example, 300 units at $25 give $7,500 in product sales. Each row shows the sum behind the number, so errors are easy to spot.

How the Amazon Revenue Calculator Works

The calculator goes from price to a clear comparison in five steps.

• First, enter your selling price and your cost for each product.
• Next, enter your monthly units sold and your advertising spend.
• Then, add your referral fee and pick your selling plan.
• After that, enter your FBA fee, storage fees, and self-ship cost.
• Finally, read the profit for both methods and the better option, and compare it with your target margin.

Amazon Revenue Calculator Inputs

Each input does a different job, as the table shows.

Input	Meaning	Why It Matters
Selling price	Price a customer pays for one unit	Drives your sales
Product cost	What you pay for one unit	Your largest cost in most cases
Units sold	Units sold each month	Scales sales and fees
Ad spend	Advertising as a share of sales	Reduces your profit
Referral fee	Percentage Amazon keeps from each sale	Applies to both methods
Selling plan	Individual or Professional plan	Changes your fixed fees
FBA fee	Fulfillment fee for each unit	Applies only to FBA
Storage fees	Monthly inventory storage cost	Applies only to FBA
Self-ship cost	Packing and postage for each order	Applies only to self-shipping

Price, cost and units set your sales and product costs. The fulfillment inputs then decide which method wins, which is why accurate fee and shipping amounts matter most.

FBA vs Self-Shipping at a Glance

Amazon describes FBA as outsourced storage and delivery, so the cost structures differ.

Item	FBA	Self-Shipping
Who ships orders	Amazon picks, packs, and ships	You pack and ship each order
Customer service and returns	Handled by Amazon, per its FBA guide	Handled by you
Main fulfillment cost	FBA fee by size and weight	Postage and packing you pay
Storage	Monthly storage fees apply	Your own space or warehouse
Referral and plan fees	Apply	Apply

Compare the full cost of each method, not just the shipping line. Your own time has a real value too.

Amazon Revenue Formula

The Amazon revenue formula subtracts shared costs once, then compares fulfillment costs.

The diagram below shows each formula step in the right order.

• First, product sales equal your selling price times the units sold.
• Next, the referral fee equals sales times your referral percentage.
• Then, advertising equals sales times your ad spend percentage each month.
• After that, product costs equal units times your cost for each unit.
• Also, FBA costs equal units times the FBA fee, plus storage.
• In addition, self-ship costs equal units times your cost for each order.
• Finally, profit for each method equals sales minus shared costs and fulfillment.

Amazon Revenue Calculator Example

Suppose a product sells for $25 and costs $6 to make. The seller moves 300 units a month, spends 10% on ads and pays 15% referral fees.

• First, product sales come to $7,500 for the whole month.
• Next, referral fees take $1,125 and advertising takes another $750.
• Then, product costs are $1,800 and the Professional plan adds about $40.
• After that, FBA at $5 a unit plus $30 storage costs $1,530.
• However, self-shipping at $6 a unit costs $1,800 in total instead.
• As a result, FBA earns about $2,255 and self-shipping about $1,985.

FBA wins by about $270, or roughly 90 cents per unit. A higher self-ship cost would widen that gap.

What Changes Your Real Amazon Profit

Real Amazon profit drifts away from the estimate for several reasons.

• Product size and weight change the FBA fee tier.
• Postage rates change by carrier, zone and package weight.
• Advertising costs often rise on new or competitive listings.
• Returns and damaged units eat into sales and margins.
• FBA storage rates can rise in the fourth quarter.
• A competitor’s price drop can cut your sales quickly, and Amazon can update its fees during the year.

Amazon Revenue Calculator Estimates vs Actual Profit

Your Seller Central reports will rarely match the estimate exactly. A few known factors explain most of the difference.

Item	Calculator Estimate	Real Report
Sales	Steady units every month	Change with seasons, ranking, and promotions
Fees	Fee amounts you enter	Depend on category, size, weight, and date
Shipping	One average cost per order	Varies by weight, zone, and carrier
Returns	Not included	Reduce revenue and may add fees

Treat the result as a planning range, not a promise. Compare it with your Seller Central reports every month, and keep a short log of the differences. Over a few months, that log makes your estimates much sharper.

Common Amazon Revenue Calculator Mistakes

Small errors add up. These are the most common ones.

• Comparing only the shipping line, when storage and time also matter.
• Guessing the FBA fee, when size and weight decide it.
• Forgetting that advertising can easily erase a thin margin.
• Leaving packing materials, labels, tape and shipping software out of your self-ship cost.
• Assuming steady sales during your first few months.
• Forgetting that every estimate here is before income tax. Tax rules differ by state and country, so ask an accountant.

Tips for Better Amazon Estimates

A few habits keep your Amazon estimates close to reality.

• Copy exact fees from Amazon for your own product.
• Test a low case with half your expected units and a high case with fifty percent more.
• Weigh and measure a packed order to find real postage, then compare quotes from at least two carriers.
• Include advertising from day one, and track ad spend separately for each product.
• Update the inputs each month as your sales change, and recheck Amazon’s fee pages whenever your product dimensions change.

Limits of the Amazon Revenue Calculator

No calculator can predict the exact profit for an Amazon product. This one uses the fees and sales you enter, not live Amazon data, and it cannot see ranking changes, reviews or competitor moves.

It also ignores returns, income tax and one-time inventory costs. Compare it with your real Seller Central reports each month.

Amazon Revenue Calculator FAQs

What is the difference between FBA and self-shipping?

With FBA, Amazon stores, packs and ships your orders and handles customer service and returns. With self-shipping, all of that is on you, so the two methods have very different cost structures.

Which is more profitable, FBA or self-shipping?

It depends on your product’s size, weight, price and order volume. FBA fees rise with size and weight, which is why the calculator compares both methods with your own numbers.

What fees does Amazon charge every seller?

Amazon lists an Individual plan at $0.99 per item sold and a Professional plan at $39.99 a month. Referral fees of 5% to 45% apply on top, depending on the product category.

Do self-shipping sellers pay FBA fees?

No. FBA fulfillment and storage fees apply only when Amazon fulfills your orders, though referral and selling plan fees still apply. The calculator drops FBA costs when you pick self-shipping.

What should I include as self-ship cost?

Include packing materials, labels, postage and any time cost you assign, plus shipping software fees if you use them. Use an average across your typical orders.

How accurate is the Amazon revenue calculator?

It is only as accurate as your inputs. Amazon fees depend on category, size, weight and other factors, so copy the exact fees from Amazon before you decide.

Conclusion

The Amazon revenue calculator turns price, fees and shipping costs into a clear comparison of the two methods. Use it to plan margins, test products and choose how to ship, then check the results against your real Seller Central data.

Fee details come from Amazon’s selling pricing page for new sellers. They also come from Amazon’s guide to FBA fees for sellers. We last checked these sources and figures on October 1, 2026.
