What Is Inventory Profit Calculator?
The Inventory Profit Calculator estimates total profit from stock sales after true per-unit costs. By combining Purchase Cost / Unit ($), Retail Selling Price / Unit ($), Inventory Units Sold, and Handling & Shipping / Unit ($), it reveals unit profit, margin, revenue, and total profit so you can judge whether inventory is worth reordering. Results are for planning and education, not financial advice — consult a professional for major decisions. The formula behind it is simple: Unit profit = Retail Selling Price / Unit ($) − Purchase Cost / Unit ($) − Handling & Shipping / Unit ($). Total gross profit = unit profit × Inventory Units Sold. Margin percent = unit profit ÷ Retail Selling Price / Unit ($) × 100.

Why Use This Tool?
Purchase price alone hides real profitability. Handling, shipping, and unsold nuances decide whether a 40 percent markup actually makes money. This tool gives a fast, honest read on inventory winners, helps set minimum viable prices, and prevents reordering stock that only looks profitable.
Common Use Cases
- Ecommerce sellers auditing SKU profitability after marketplace fees and fulfillment costs.
- Boutique retailers deciding which lines to reorder, mark down, or discontinue.
- Wholesalers testing price breaks and freight scenarios on bulk deals.
- Amazon and eBay sellers estimating net profit per unit before scaling ad spend.
- Warehouse managers comparing suppliers on landed cost plus handling impact.

Frequently Asked Questions
Should I use landed cost?
You can. Either add freight into Purchase Cost / Unit or keep freight in Handling & Shipping / Unit, but do not count the same cost twice.
How do returns affect profit?
Reduce Inventory Units Sold to net units kept by customers, or lower Retail Selling Price to an average after refunds for a conservative estimate.
Does it include storage rent?
No. Include only per-unit handling and shipping here. Allocate monthly warehouse rent separately across expected units when reviewing total profitability.
What margin should I target?
Many retailers target 30 to 60 percent unit margin depending on category, competition, and overhead. Compare to your fixed costs and turnover rate.
Can I compare suppliers?
Yes. Run the same Retail Selling Price and Units Sold with each supplier Purchase Cost and Handling figure to see who leaves more profit.
Is this financial advice?
No. Outputs are planning estimates based on your inputs. For tax and inventory valuation, consult a qualified professional.
Tips for Getting the Best Results
- Use net units sold: subtract returns and cancellations from Inventory Units Sold for realistic profit.
- Capture all per-unit fees: include marketplace commissions averaged per unit in handling where appropriate.
- Re-check freight often: update Handling & Shipping as carrier rates change to avoid margin drift.
