Reselling
Bulk Lot Pricing Calculator
You bought a lot, not a single item. Split the lot cost across every piece and find the per-item price that still leaves a profit after fees and shipping.
Total profit is what the whole lot earns after fees, per-item shipping and the lot cost itself; per-item profit divides that by sellable units. The break-even price is the lowest average price at which the lot exactly covers its own cost, fees and shipping — price below it and the lot loses money even if every piece sells.
Formula
Cost per item = lot cost ÷ sellable units. Revenue = units × average price. Fees = revenue × fee rate. Profit = revenue − fees − (units × shipping per item) − lot cost. Break-even price = (cost per item + shipping per item) ÷ (1 − fee rate).
How it works
Enter what the lot cost, how many pieces you can actually sell (not how many arrived — damaged and unsellable pieces do not count), your expected average selling price, a blended fee rate for where you will sell, and shipping plus packaging per item. Unsellable pieces raise the cost of every good piece, which is why the sellable count matters more than the headline lot size.
Worked example
Lot cost $200.00 for 40 sellable units = $5.00 per item. At $15.00 each, revenue = $600.00. Fees at 13% = $78.00. Shipping and packaging 40 × $3.50 = $140.00. Profit = $600.00 − $78.00 − $140.00 − $200.00 = $182.00, or $4.55 per item. Break-even price = ($5.00 + $3.50) ÷ (1 − 0.13) = $9.77 per item.
FAQs
Why use sellable units instead of total units?
Because unsellable pieces still cost money. If 50 pieces arrive but only 40 sell, the 10 dead pieces are paid for by the 40 good ones — dividing by 50 would understate your true cost per sale.
What fee rate should I enter?
A blended rate for where you will actually sell. If half the lot goes to a 20% marketplace and half to a 10% one, 15% is a fairer planning figure than either extreme.
What if items sell at very different prices?
Use a realistic average, or split the lot into groups (high, mid, low value) and run the calculator once per group. One average hides a lot where a few stars carry many duds.
Does this include my time?
No. Sorting, cleaning, photographing and listing a lot takes hours. If your per-item profit is $4.55, divide it by your time per item to see whether the lot is worth the work.
Should I include storage or mileage?
If they are real costs of this lot, add them to the lot cost field. The calculator only knows the costs you enter.
