Solve the mystery: "How much should I list this for?"
This is a dedicated calculation tool designed to ensure you secure the exact "Take-home Profit" you want on marketplace apps.
From platform fees and shipping to those often-overlooked "Packaging Costs"—by entering your specific expenses, you can prevent losses due to calculation errors and determine the perfect selling price every time.
【How to Use】It’s simple. Just enter these four items:
・Target Profit: The amount you want to keep.
・Fee Rate: The commission percentage of the platform.
・Shipping: The cost of postage/delivery.
・Packaging: Costs for boxes, mailers, or bubble wrap.
The app instantly displays the "Required List Price" that covers all your costs.
【Perfect For...】
Preventing Losses: Avoid frustrating mistakes where you forget packaging or shipping costs and end up with little to no profit.
・Flexible Settings: Easily adjust for different platform fees (10%, 5%, etc.) and your own unique packaging expenses.
・Smart Price Negotiations: When a buyer asks for a discount, re-enter your costs to instantly see your "bottom line" price and make a quick decision.
【Key Features】

・Manual input for fees, shipping, and packaging costs.
・Offline-friendly: No unnecessary data usage with a simple, fast interface.
