The Open buttons send the prompt text as currently shown below to that site only when you click. Fill in the placeholders first.
[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.

Inputs (enter current fees): listing fee 0.20, transaction fee 6.5% of price + shipping, payment processing 4% + 0.20. Worked example (made up): item cost 8.00, packaging 0.60, labor 0.5 h at 15/h = 7.50, shipping charged 4.00 (actual 3.80). Total cost = 8.00 + 0.60 + 7.50 = 16.10. Price needed for a 30% margin on price: solve P - fees - 16.10 = 0.30P. Fees = 0.20 + 6.5% x (P + 4.00) + 4% x (P + 4.00) + 0.20 = 0.40 + 0.105(P + 4.00). 0.70P - 0.105P - 0.42 - 0.40 = 16.10 -> 0.595P = 16.92 -> P = 28.44. Verify fees against official pages.
