This tool calculates the minimum selling price (the "bottom price") you need to set on platforms like eBay, Poshmark, or Mercari to guarantee you achieve a specific profit. It's designed for online resellers who need to quickly factor in all fees and costs before listing an item or accepting a negotiation offer.

🧐 Frequently Asked Questions
Q. What exactly is the "bottom price"?
A. It's the lowest possible price you can sell your item for to cover all expenses (platform fees, shipping, packaging) AND achieve your target profit. Selling for any amount below this price means you will not reach your profit goal; you might even lose money.
Q. Why is the "Actual Profit" sometimes slightly higher than my "Target Profit"?
A. To ensure all costs and your profit are fully covered, the calculator always rounds the final bottom price up to the next cent (or whole number, depending on the currency). This slight upward rounding can result in an actual profit that is marginally higher than the target you entered. It's a built-in safeguard to protect your earnings.
📚 The Resale Pricing Formula
A common mistake among online sellers is underestimating the impact of platform commission fees. Since these fees are a percentage of the final selling price, you can't simply add them to your costs. For example, if you want to make $10 after costs and the fee is 10%, pricing at $11 won't work because the platform will take $1.10, leaving you with only $9.90.
This calculator solves that problem by using the correct formula: Selling Price = (Total Costs + Target Profit) / (1 - Commission Rate). This reverse calculation ensures that after the platform takes its percentage-based cut, you are left with enough money to cover your initial expenses and secure the exact profit you planned for. This approach gives you a crucial psychological anchor, allowing you to negotiate confidently and price your items strategically from the start.
