1. Key Metrics for Your FBA Profit Calculator

Your calculator should include the following fields:

| Metric | Description | Formula |
|---------------------------|----------------------------------------------------------------|------------------------------------------|
| Selling Price | The price you sell the product for on Amazon. | Input |
| Cost of Product | The cost of manufacturing or purchasing the product. | Input |
| Shipping Cost | The cost of shipping the product to Amazon’s FBA warehouse. | Input |
| Amazon Referral Fee | A percentage of the selling price (usually 15%). | Selling Price × Referral Fee (%) |
| FBA Fulfillment Fee | Fee charged by Amazon for storage, packing, and shipping. | Input (lookup based on size/weight) |
| Total Costs | All costs combined. | Cost of Product + Shipping + Fees |
| Net Profit | How much you earn after costs. | Selling Price - Total Costs |
| Profit Margin (%) | The percentage of revenue that is profit. | (Net Profit ÷ Selling Price) × 100 |
| ROI (%) | Return on investment, a measure of profitability. | (Net Profit ÷ Cost of Product) × 100 |

2. Step-by-Step Setup

Step 1: Create Your Spreadsheet

1. Open Google Sheets or Excel.
2. Label the first row with headers for each key metric:
3. "Selling Price," "Cost of Product," "Shipping Cost," "Referral Fee," "FBA Fulfillment Fee," "Total Costs," "Net Profit," "Profit Margin," and "ROI."

Step 2: Add Input Fields

• Create input fields where you can manually enter values:
• Selling Price (e.g., $25).
• Cost of Product (e.g., $8).
• Shipping Cost (e.g., $2).
• FBA Fulfillment Fee (e.g., $3.50 based on weight).

Example Layout:

| Metric | Example Value | Formula |
|----------------------|-------------------|-------------|
| Selling Price | $25 | Input |
| Cost of Product | $8 | Input |
| Shipping Cost | $2 | Input |
| Referral Fee (%) | 15% | Fixed |
| FBA Fulfillment Fee | $3.50 | Input |

---

Step 3: Add Formulas

1. Referral Fee:
   Formula:
   [ {Referral Fee} = {Selling Price} * 0.15 ]
   Example: If the selling price is $25:
   [ 25 * 0.15 = \$3.75 ]

2. Total Costs:
   Formula:
   [ {Total Costs} = {Cost of Product} + {Shipping Cost} + {Referral Fee} + {FBA Fulfillment Fee} ]
   Example:
   [ 8 + 2 + 3.75 + 3.50 = \$17.25 ]

3. Net Profit:
   Formula:
   [ {Net Profit} = {Selling Price} - {Total Costs} ]
   Example:
   [ 25 - 17.25 = \$7.75 ]

4. Profit Margin (%):
   Formula:
   [ {Profit Margin} = \left(\frac{{Net Profit}} / {{Selling Price}}\right) * 100 ]
   Example:
   [ \left(\frac{7.75}{25}\right) * 100 = 31\% ]

5. ROI (%):
   Formula:
   [ {ROI} = \left(\frac{{Net Profit}} / {{Cost of Product}}\right) * 100 ]
   Example:
   [ \left(\frac{7.75}{8}\right) * 100 = 96.88\% ]

Step 4: Automate with Formulas in the Spreadsheet

Here’s how your spreadsheet might look after adding formulas:

| Metric | Example Value | Formula (for reference) |
|-------------------------|-------------------|-----------------------------------------------------|
| Selling Price | $25 | Input |
| Cost of Product | $8 | Input |
| Shipping Cost | $2 | Input |
| Referral Fee | $3.75 | =B2*0.15 |
| FBA Fulfillment Fee | $3.50 | Input |
| Total Costs | $17.25 | =B3+B4+B5+B6 |
| Net Profit | $7.75 | =B2-B7 |
| Profit Margin (%) | 31% | =(B8/B2)*100 |
| ROI (%) | 96.88% | =(B8/B3)*100 |

---

3. Additional Features to Add

A. Conditional Formatting

• Highlight low-profit products by setting a rule:
• If Profit Margin < 30%, the cell turns red.
• If ROI < 100%, the cell turns yellow.

B. Bulk Product Analysis

• Create multiple rows to analyze multiple products simultaneously.

| Product Name | Selling Price | Cost of Product | Net Profit | Profit Margin (%) | ROI (%) |
|------------------------|-------------------|---------------------|----------------|------------------------|-------------|
| Bamboo Cutting Board | $25 | $8 | $7.75 | 31% | 96.88% |
| Yoga Mat | $20 | $10 | $3.50 | 17.5% | 35% |

C. Break-Even Price Calculator

Add a formula to determine the minimum price to break even:
[ {Break-Even Price} = {Total Costs} ]

Example:
If Total Costs = $17.25, the Break-Even Price is $17.25.
