eBay Break-Even Calculator

How to use this calculator

1. Enter your numbers in each field above — the calculator updates instantly as you type, so there's nothing to submit.
2. Use your real figures when you have them, or sensible estimates while you're planning. If a field doesn't apply, leave it at zero.
3. Compare the results, then change one input at a time to see how each lever (price, cost, fees, volume) moves the outcome.

Formula

Total monthly expenses = Store subscription + Advertising + Software + Other · Break-even sales = ⌈Total monthly expenses ÷ Average profit per item⌉ · Break-even revenue = Break-even sales × Average sale price · Sales per week ≈ Break-even sales ÷ 4.33 · Sales per day ≈ Break-even sales ÷ 30

Worked example

Average sale price $35, average profit per item $8 (after eBay fees, product cost, and shipping). Monthly costs: Basic Store $27.95, Promoted Listings $75, listing software $20, supplies and mileage $15.

1. Total monthly expenses = 27.95 + 75 + 20 + 15 = $137.95
2. Break-even sales = ⌈137.95 ÷ 8⌉ = 18 items/mo
3. Break-even revenue = 18 × 35 = $630
4. Sales per week = 18 ÷ 4.33 ≈ 4.2
5. Sales per day = 18 ÷ 30 ≈ 0.6

Answer: 18 items/mo · $630 in revenue · ~4 sales/week · ~1 sale every 2 days

How it works

How to interpret your results

• Dollar values are shown per sale, per order, or per item unless a result is explicitly labelled monthly, weekly, or daily.
• Percentages (margin, ROI, conversion rate) are easier to compare across products and price points than raw dollars — use them when you benchmark.
• A positive result means you're ahead after the costs and fees you entered. A negative result means the current numbers don't work — change a lever (raise price, cut a cost, lower ad spend) and recalculate.
• Treat the output as a planning estimate, not a guarantee. Fees, taxes, and conversion rates shift over time — re-run the numbers whenever a key input changes.

Common mistakes

• Using sale price as profit per item — eBay's final value fee, product cost, and shipping you pay all have to come out first.
• Forgetting the eBay Store subscription is a fixed cost — Anchor at $349.95/mo turns into ~44 items/mo of break-even on an $8 profit/item.
• Treating Promoted Listings spend as variable — if you set a monthly campaign budget, it behaves like a fixed cost from a break-even standpoint.
• Ignoring software subs (Vendoo, List Perfectly, accounting tools) that quietly add $30–$100/mo of fixed cost.
• Calculating only break-even revenue and forgetting to translate it into a daily sales pace you can actually hit.

FAQ

What is an eBay break-even point?

It's the number of items (and revenue) you need to sell in a month for total profit to equal zero — your product costs and eBay fees are covered on every sale, and your Store subscription, ads, and software are paid for the month. The next item you sell is the first one that contributes real profit.

How is this different from the general Break-Even Calculator?

The general Break-Even Calculator solves one-time investment break-even (e.g. recover a $300 startup cost). The eBay version handles recurring monthly costs that an eBay seller pays every month — Store subscription, Promoted Listings, software, and other overhead.

What profit per item should I enter?

Use net profit after eBay's final value fee, product cost, and shipping you pay. If you're not sure, run a sale through the eBay Profit Calculator first, then bring that figure back here.

Do I need an eBay Store subscription?

Not at all. If you sell as a casual seller without a Store, enter 0 for the subscription. Stores make sense once your monthly insertion-fee discounts and final-value-fee reductions outweigh the subscription cost — a separate decision from break-even.

How should I treat Promoted Listings ad spend?

If you commit to a monthly Promoted Listings budget, enter it under Monthly advertising — it's effectively a fixed cost. If you only run Promoted Listings on a per-sale ad-rate basis, fold that ad fee into the per-item profit instead.

Is break-even the same as profitability?

No. Break-even is zero profit — you're not losing money but you're not making any either. Most sellers aim for at least 1.5–2× break-even sales per month so a slow week doesn't put the business in the red.

How can I lower my break-even sales count?

Raise profit per item (better sourcing, fewer discounts, charge shipping), trim fixed costs (downgrade Store tier, cut unused software, audit Promoted Listings), or improve listing conversion so existing traffic produces more sales without adding fixed cost.
