Questions and answers

Enter your item cost, prep cost, planned sale price, shipping charged, seller discount, label cost, and packaging cost. Fees, net profit, margin and ROI are calculated from what you enter.

The Platform Fee Settings tab. Each fee is looked up by platform, component and date, so no fee number is typed into a formula.

Yes. Every row in Platform Fee Settings was verified against the official platform fee page shown in its Source URL column, on the date in its Verified date column. Fees change during the year, so re-check a row against its source (about two minutes) before big decisions. If a fee changed, add a new row and update Setup's verified date.

Add a new row to Platform Fee Settings with the new value and its effective date. Never edit an old row.

No. This is a records and what-if tool, not tax, accounting, or legal advice.

Timing differences, rounding, sales tax handling (tax is info-only here and never enters the fee math, while some platforms include it in their fee base), and ads or promo fees you didn't enter. Each fee row's Verified date and Source URL show exactly what was checked and when.

Email [email protected]. We typically reply within 2 business days. Support covers the file not working as described, broken formulas in a copy whose formulas you haven't changed, unclear instructions, and entering a published fee update. It doesn't cover custom changes, bookkeeping, tax or accounting questions, coaching, or copies with edited formulas. We will never ask for edit access to your file, your marketplace passwords, or your bank details.

Here, in full: ProfitStamp spreadsheets are educational record-keeping tools. They do not provide tax, legal, accounting, or financial advice; consult a qualified professional for your situation. ProfitStamp is not affiliated with, endorsed by, or sponsored by eBay, Poshmark, Mercari, Depop, or Etsy; all trademarks belong to their owners. Fee values were verified as of the date shown in the file and may change; verify against official platform fee pages. Results depend on your own business; no earnings are implied or guaranteed. Modifying formulas is at your own risk and voids support for affected calculations.

Grey columns are calculated. Sheets shows a "Heads up!" warning before you type in one; if you clicked OK anyway, that column goes blank and its header shows #REF!. To fix it: click the cell you typed in, press Delete, and click OK on the warning. The whole column fills itself back in and nothing is lost. Type only in yellow cells.

Sample rows are pre-filled so nothing is blank; each has SAMPLE in the column headed Tag. Remove them tab by tab in this order: Sales, then Inventory, then Sourcing Lots, then Expenses. On each tab: Data ▸ Create a filter; click the filter button in the Tag header, make sure only SAMPLE is ticked, and click OK (untick "(Blanks)" if it is listed, so empty rows are kept); select the visible rows, right-click ▸ Delete selected rows ("Delete row" when there is only one); then Data ▸ Remove filter. Sheets may show a "Heads up!" warning when you create, apply or remove the filter and when you delete rows; that is expected, click OK. Finally set Sample data present? to NO in Setup and tick "Deleted sample data" above.

Fee-change notices and fixes are included for 6 months from your purchase. When a platform changes a fee in that time, we send the exact values to enter through the store you bought from. After that, enter fee changes yourself from the official fee pages. Add them as a new row at the bottom of Platform Fee Settings; the empty rows below the listed fees are there for this. Never edit an existing row.

Use one Sales row per SKU, all with the same Order ref. A fixed per-order fee is then counted once, on the order's first row. On platforms whose fee depends on the order total, copy the exact fee from the platform's order page into the Marketplace fee override on one row and 0 on the others. A filled Override always wins.

Don't delete the row; change its Status instead. Pick Refunded – Restocked if the item came back to stock, or Refunded – Not restocked if it didn't. Then set Fees returned? from your platform statement: Y (fees credited back), N (fees kept), or Partial (type the fee the platform kept into the fee Override columns). For a partial refund, choose Partial refund and type the amount in Refund amount.

Log a Sales row with Status Giveaway and Item price 0. Its item cost and any label you paid still count, so it shows as a negative profit, which is what the giveaway cost you. Don't use Qty removed on Inventory for giveaways.

Open the All sheets menu (the ☰ button at the bottom left) and choose Lists to show that hidden tab. On the lst_categories row, type your category in the first empty cell after Mixed. Then right-click the Lists tab ▸ Hide sheet. The new category appears in the Category dropdowns.

See the Upgrade panel on the Start Here tab.

Grey cells are calculated and locked. If you typed over one, press Ctrl+Z (Undo) right away. If that is no longer possible, start again from a fresh copy of the template. Type only in yellow cells.

Type your own values into the yellow input cells. The sample numbers are only there so you can see the calculator working; there is nothing else to delete in this edition.

Fee-change notices and fixes are included for 6 months from the day you got your copy. When a platform changes a fee in that time, we email the exact values to enter to the address you signed up with. After that, enter fee changes yourself from the official fee pages. Add them as a new row at the bottom of Platform Fee Settings; the empty rows below the listed fees are there for this. Never edit an existing row.

No. ProfitStamp Pro is the top edition. A live-show module for live sellers is coming as a free update once its fee rules are verified; you will get a new copy link through the store where you bought it.
