The free reseller spreadsheet that tracks profit, not sales.

Every reseller template on Etsy computes price minus fees and calls it a day. This one prices the six costs your platform dashboard hides — COGS, shipping you ate, supplies, your time, returns, mileage — and rolls it all into a monthly P&L you could hand an accountant.

Built for eBay, Poshmark, Mercari, Depop, Whatnot, and Amazon sellers. Works in Excel and Google Sheets. No macros, no add-ons, nothing to maintain except two fee cells about once a year.

What one sale actually looks like

This is the worked example on the sheet's Walkthrough tab — live formulas, current fee schedules (verified June 2026).

Line	Amount
Sale price (thrifted fleece, eBay)	$24.99
eBay fee (13.25% of price + shipping, + $0.40 order fee)	−$4.50	the only cost your dashboard charges
What the dashboard calls profit	$20.49
COGS	−$6.50	hidden cost 1
Shipping you ate (label − buyer-paid)	−$0.81	hidden cost 2
Supplies	−$0.65	hidden cost 3
Your time (15 min at $15/hr)	−$3.75	hidden cost 4
Return reserve (3%)	−$0.75	hidden cost 5
What you actually kept	$8.03	39% of what the dashboard claimed

Sales Log tab: yellow input columns on the left, automatic columns on the right — dashboard margin $20.49 next to REAL margin $8.03 on the same sale — The actual Sales Log, shown with the walkthrough example data. Yellow = you type, green = automatic.

The sheet shows both numbers side by side on every sale — and the Dashboard tab totals the gap: what your dashboards overstated this year, in dollars. The method is written up here.

Dashboard tab: real profit vs what your dashboards claimed vs what they overstated, death pile items and dollars, 90-day sell-through rate, average days to sale — The Dashboard tab, computed live from the logs (walkthrough example data shown).

What's inside — eight tabs

Start Here. One-minute setup, the daily workflow, and how to read your results. The sheet opens here.
Settings. Your hourly rate, return reserve %, supplies cost, and tax-reserve % — the assumptions the whole sheet runs on.
Inventory Log. One row per item: pre-printed stable SKU, item description, source, purchase price (COGS), status, days held, and 90/180/365 aging flags. Your death pile gets counted, not ignored.
Sales Log. Enter the sale, get both margins: the "dashboard margin" your platform shows, and the real margin after COGS, shipping you ate, supplies, your time, and a return reserve. Fees compute automatically per platform, and a mistyped SKU flags CHECK SKU instead of silently counting $0 cost.
Dashboard. Real margin by platform (where to list), real margin by source (where to source), 90-day sell-through, average days to sale, and the death-pile counter — items and dollars — each with a one-line definition.
Monthly P&L. Twelve months, auto-rolled from the Sales Log: gross sales → fees, COGS, shipping, supplies, mileage → gross profit → tax reserve → profit after tax reserve.
Fees. Every platform fee constant in one reference tab, with verification dates. When a platform changes its schedule, you update two cells — nothing else.
Walkthrough. A filled-in example — five items bought, three sold — running on the same live formulas, so you can poke at it. Your real logs start clean.
