Set a cost-plus price that actually hits your target — margin or markup, clearly told apart — with marketplace fees already baked in.

How we calculate this
This calculator turns your unit cost into a price that actually hits your target — whether that target is a margin (profit as a percent of price) or a markup (profit as a percent of cost), two numbers owners constantly swap by accident. It also bakes marketplace fees into the price up front, so a "50% margin" is still 50% after Amazon or Etsy takes its cut, not just on the sticker.
The formulas
- Target expressed as a margin
- margin mode: target margin = target %; markup mode: target margin = markup ÷ (1 + markup)Both modes are solved through an equivalent margin — a 50% markup is only a 33.3% margin.
- Recommended price (fee-adjusted cost-plus)
- (unit cost + fixed fee per order) ÷ (1 − target margin − channel fee %)With no fees this reduces to cost ÷ (1 − margin), or cost × (1 + markup) in markup mode. If target margin + fees reach 100%, no price works.
- Profit per unit
- price × (1 − channel fee %) − fixed fee per order − unit cost
- Effective margin after fees
- profit per unit ÷ priceThe sticker margin (price − cost) ÷ price will look higher whenever fees are in play — the effective margin is the real one.
Worked example
- Say your total landed unit cost is $20, you target a 50% margin, and you sell with no channel fees.
- Price = $20 ÷ (1 − 0.50) = $40.
- Profit per unit = $40 − $20 = $20, which is a 50% margin on the $40 price — and the same price expressed against cost is a 100% markup.
- If you had instead asked for a 50% markup, the price would be $20 × 1.5 = $30 — only a 33.3% margin. Same "50%", ten dollars of difference.
- Add a 15% channel fee and a $2 fixed fee per order on that $20 cost, and holding a true 50% margin pushes the price to ($20 + $2) ÷ (1 − 0.50 − 0.15) = $62.86 — fees are paid by the price, not by your profit, only if the price accounts for them.
Rates, benchmarks & sources
- Price = cost ÷ (1 − margin); price = cost × (1 + markup); fee-adjusted price = (cost + fixed fee) ÷ (1 − margin − fees) — Standard cost-plus pricing algebra
- ~20% effective-margin floor most product businesses need — a heuristic, not a standard — Rule of thumb (spec §2.4)

What this tool doesn’t model
- Cost-plus pricing ignores what customers will pay — it guarantees your economics if the product sells, not that it sells; market and competitor pricing still bound the answer.
- Channel fees are entered as one flat take rate; real marketplace fee schedules vary by category, fulfillment method, and promotions — check the platform fee calculators for your exact cut.
- It prices one unit in isolation: no volume discounts, bundle economics, shipping subsidies, or returns/refunds, all of which reduce realized margin.
- The ~20% margin floor is a rule of thumb for product businesses generally, not a threshold for your niche.
Frequently asked questions
Should I price to a target margin or a target markup?
Either works as long as you know which one you are using — the trap is setting a "50% markup" while your spreadsheet assumes a 50% margin. Margin measures profit against the price; markup measures it against the cost. A 50% markup is only a 33.3% margin, so the two labels on the same number produce very different prices. The tool shows every price both ways so the ambiguity disappears.
Why is the recommended price higher than cost ÷ (1 − margin)?
Because you entered channel fees, and the tool holds your margin after those fees. If it priced with the simple formula and the platform then took its cut, your real margin would land below target — that is the fee-erosion problem the calculator exists to prevent. The fee-adjusted formula divides by (1 − margin − fees), so the fee is built into the sticker price.
What happens when my target margin plus fees reach 100%?
No finite price can achieve it. The margin is a share of the price and the fees are a share of the price; if together they claim 100% or more, there is nothing left to cover the cost at any price. The tool shows a warning instead of a number — the fix is a lower margin target, a cheaper channel, or both.
What should I include in unit cost?
Everything it takes to get one unit ready to sell: materials, direct labor, packaging, and inbound freight — the total landed cost. Leaving out packaging or freight is the most common way sellers overstate their margin. Overhead like rent and marketing stays out of unit cost; it gets covered by the margin, which is why the margin cannot be razor-thin.
Is a 20% margin too low for a product business?
As a rule of thumb, effective margins under roughly 20% leave little room for overhead, returns, ad spend, and mistakes — which is why the tool raises a caution flag below that line. It is a heuristic, not a law: high-volume or low-touch products can work thinner, and handmade or heavy-service products usually need much more. Treat the flag as a prompt to check your fixed costs, not as a verdict.
