How is it calculated?
Profit per sale: from average sale and supply price with the same engine as the Profit Calculator (final value fee, per-order fee, tax, cashback, ads, return share).
Monthly sales = listings × sell-through. Sales profit = sales × profit per sale. Then subscription (plan and billing), over-allowance insertion fees and fixed monthly costs are subtracted.
Scenarios: sell-through ×0.7 (pessimistic), ×1 (expected), ×1.3 (optimistic). Growth: net new listings each month; sell-through is assumed constant; insertion fees change with listing count.
Break-even: the monthly sales and listings that cover the costs. Target: the sales and listings your monthly profit target needs. The table shows net and cumulative month by month.
Frequently asked questions
What is sell-through and how do I estimate it?
Monthly sales divided by active listings. 12 sales a month on 100 listings = 12%. 5–10% is typical when starting, 10–20% for established stores; replace it with your own history.
Why ask for an average supply price instead of letting me type the profit?
The engine computes profit per sale: eBay fees change with price and plan, Amazon tax and cashback change the cost. Typing average prices is more reliable than assuming 'my profit is $10'.
How is growth modelled?
Each month the net listing growth is added; sell-through stays constant; insertion fees for listings above the allowance rise automatically. Remember sell-through can fall with volume; look at the pessimistic scenario too.
What should I put in fixed costs?
Monthly costs independent of sales: software subscriptions (Sellerviva included), bookkeeping, exemption filings, bank fees. Don't add the store subscription; it comes from the plan you pick.
Are these numbers guaranteed?
No; it is an estimate based on your inputs. Returns, cancellations, Amazon price changes and eBay rule changes move the result. eBay fees come from the official 2026 table; the date is under the result box.
