How This Works

ROI = (Total Profit - Initial Investment) / Initial Investment x 100

Your initial investment includes all upfront costs: inventory, shipping, photography, launch PPC budget, and any other costs incurred before your first sale.

The break-even month is when your cumulative profit equals your initial investment. After that point, every dollar of profit is pure return on your investment.

The month-by-month table shows your net position at each point: negative means you have not yet recouped your investment, positive means you are in profit territory.

Frequently Asked Questions

Include all upfront costs: product inventory (first order), shipping to Amazon, product photography, listing creation, packaging design, UPC/barcode costs, initial PPC budget, and any product samples. A typical first product launch ranges from $2,000 to $10,000 depending on the product and order quantity.
Most successful Amazon sellers target 100% or higher annual ROI, meaning they double their investment within a year. A 50-100% ROI is considered decent, while above 200% is excellent. New sellers should aim to at least break even within 3-6 months of launching their first product.
The typical break-even timeline is 3-6 months for well-researched products with a solid launch strategy. Products in competitive niches or those requiring heavy PPC investment may take 6-12 months. If you have not broken even within 12 months, it may be time to reassess the product or strategy.
Most experienced sellers recommend reinvesting 70-80% of profits back into inventory and new products during the first 1-2 years. This compounds your growth significantly. Once you have multiple profitable products, you can start taking a larger percentage as personal income while still funding growth.
This calculator uses a fixed monthly profit for simplicity. In reality, profits vary due to seasonality, PPC optimization, and price changes. For more accuracy, use your average monthly profit over the last 3-6 months. Track actual vs. projected ROI monthly and adjust your strategy accordingly.
