The calculator
The boxes start filled with an illustrative example, not a benchmark. Replace it with your own numbers. All figures are per unit.
Landed product cost per unit: what you paid the supplier, plus freight and duty to get it to you.
What it costs you to ship one unit to the customer, not what you charge them for shipping.
Pick, pack, packaging, or anything else that scales with the sale. Zero is fine if nothing else applies.
Stripe, PayPal, and most other processors charge a percentage plus a small flat fee per order.
Absolute price floor
Below $25.03, this product loses money on every sale, before any profit at all.
price floor = (COGS + outbound shipping + other variable cost + payment flat fee) / (1 - payment processing rate / 100)
This is the price at which contribution margin is exactly zero: nothing left over for fixed costs or profit, but also no loss on the unit itself.

This is the absolute per-unit floor: the price at which contribution margin hits exactly zero. It says nothing about whether that price also covers fixed costs like rent, salaries, and software, the costs that do not scale with any single sale.
Covering fixed costs is a store-wide break-even question, a different and bigger calculation than this per-unit one. A price above this floor can still leave the store as a whole losing money if volume is too low to clear fixed costs on top of it.
Questions
The lowest price you can charge for a unit and still cover every cost that scales with that specific sale: product cost, shipping, and payment fees. Below the floor, you lose a little money on every single unit sold, regardless of volume.
Not quite. This floor is a per-unit number: the price where contribution margin on one sale is exactly zero. Store-wide break-even is a different, bigger question, it asks how many units at a given price it takes to also cover fixed costs like rent and salaries. This calculator answers the first question, not the second.
Because it is a real cost taken out of every single sale, the same way shipping is. Leaving it out understates the true floor, sometimes by a meaningful amount depending on your processor's rate.
That is worth flagging to yourself. A price sitting right at or just above the floor leaves no room for fixed costs, profit, discounts, or returns. It can look fine on a single sale and still be unsustainable across the business.
Sometimes, deliberately, as a loss leader meant to bring in a customer who buys other things too, or to move inventory that would otherwise cost more to hold. That should be a conscious choice made with the real numbers in front of you, not something that happens by accident because nobody calculated the floor.

Upstream reads real per-SKU landed cost, real shipping, and real payment fees from your store, so the floor price for every product is calculated automatically, not typed in by hand.
