Reverse Fee & Break-Even Price Calculator
Work backward from your required net dollar profit or target profit margin percentage to mathematically derive the exact selling price to list on any marketplace.
Target Margin & Pricing Solver
Calculate the required listing price across each marketplace to achieve a specific target dollar profit or margin percentage.
How Reverse Pricing and Break-Even Calculation Works
Stop guessing your listing prices. Derive exact break-even thresholds and profit markup guarantees.
1. Break-Even Price (Zero Net Profit)
The break-even price is the exact minimum sale price where you recover 100% of your product acquisition cost, shipping expenses, and all platform transaction cuts without losing money.
2. Target Dollar Profit Mode
Specify an exact net dollar return (e.g., $25.00 net profit). The solver dynamically adjusts for escalating percentage commissions and sales taxes to solve the required list price.
3. Target Profit Margin (%) Mode
Set your target margin percentage (e.g., 30% Net Margin). The algorithm calculates the necessary markup to cover all variable marketplace cuts and fixed processing costs.
4. Multi-Channel Pricing Protection
Because platforms like Poshmark (20%), eBay (13.25%), and Depop (0% fee + 3.3% card) have differing fee structures, reverse pricing lets you set tailored list prices on each channel.
