[VERIFY] is an editorial flag, not a blank to fill. Wherever the prompt shows [VERIFY], check that item against a reliable source before you use it.
Design a pricing calculator for my products. Marketplace(s) and fee structures (listing fee, transaction fee, payment processing, ads, currency conversion): [FEE_STRUCTURES]. Verify these against the current official fee pages: [VERIFY]. Product cost inputs (materials, labor time and my hourly target, packaging, shipping supplies): [COST_INPUTS]. Shipping charged to buyer and actual shipping cost: [SHIPPING]. Target profit margin: [TARGET_MARGIN]. Sales tax or VAT treatment (to verify with an accountant): [TAX_NOTES]. Return: 1. A table of inputs and formulas: Item | Formula | Example. Include total cost per unit, fees as a function of price and shipping charged, break-even price, price needed for the target margin (solve algebraically; show how to account for percentage-based fees), profit per unit, and profit per hour. 2. A worked example with made-up numbers and the arithmetic. 3. A spreadsheet layout with named input cells and formulas (written for common spreadsheet apps). 4. Sensitivity: price changes of 5 and 10 percent; effect of free shipping offers; effect of offsite ad fees on selected orders. 5. A decision tree for discounts and sales (never below break-even). 6. Reminders to include returns, breakage, and time spent on messaging. Do not assume fee percentages; ask me to enter current ones. This is a planning tool and not tax or accounting advice.
