Selling on Amazon can look easy at first. You buy goods, list them, and make sales. But fees can cut your gain fast. Our Amazon Profit Calculator helps you see the full cost.

You can add your buy price, sales price, units, ship cost, and fees. The tool then shows gross profit, net profit, ROI, and profit margin.

Think of it as a quick money check. It can help you spot a good deal before you put cash into stock.

Amazon Profit Formula

The math is simple. The tool uses these key formulas.

Total Buying Cost = Buying Price × Buying Quantity

Total Sales = Selling Price × Selling Quantity

Gross Profit = Total Sales − Total Buying Cost

Referral Fee = Total Sales × Referral Fee % ÷ 100

Total Fees = Referral Fee + Other Fees

Net Profit = Gross Profit − Shipping Cost − Total Fees

Total Investment = Total Buying Cost + Shipping Cost + Total Fees

ROI = Net Profit ÷ Total Investment × 100

Profit Margin = Net Profit ÷ Total Sales × 100

Here’s a simple way to view it. Sales bring cash in. Costs take cash out. The cash left at the end is your net profit.

Example Amazon Profit Calculation

Let’s say you buy 50 items at $20 each. You sell 50 items at $35 each. Your ship cost is $80. Your fee rate is 15%. Other fees are $100.

Total Buying Cost = $20 × 50 = $1,000

Total Sales = $35 × 50 = $1,750

Gross Profit = $1,750 − $1,000 = $750

Referral Fee = $1,750 × 15% = $262.50

Total Fees = $262.50 + $100 = $362.50

Net Profit = $750 − $80 − $362.50 = $307.50

Total Investment = $1,000 + $80 + $362.50 = $1,442.50

ROI = $307.50 ÷ $1,442.50 × 100 = 21.32%

Profit Margin = $307.50 ÷ $1,750 × 100 = 17.57%

So, the net profit is $307.50. The ROI is 21.32%. The profit margin is 17.57%.

Amazon FBA Profit Calculator

An Amazon FBA Profit Calculator can help you check a deal before you buy stock. You can use it to test price, cost, and fee changes.

It can also work as an Amazon Seller Profit Calculator or Amazon Product Profit Calculator. You can use it to check sales and costs for a new item.

For US sellers, use your US price and fee data. For UK sellers, use your UK data. The same idea works for India and other markets.

Keep in mind that Amazon fees can vary by item and market. So, use the best fee data you have.

Amazon Profit Margin Calculator

Profit tells you how much cash you have left. Profit margin tells you how much of each sales dollar you keep.

For example, a 20% profit margin means you keep $20 for each $100 in sales after the costs in the tool.

ROI is also key. It shows how well your cash works for you. A deal with a high sale price may still give a poor ROI if costs are too high.
