Repricing Floor Price Calculator

Works out the lowest price a product can drop to before it stops earning your minimum margin, so you can set a safe floor in any repricing rule, for online sellers on their own store or a marketplace.

Your estimate

Break-even price...

Floor price at your minimum margin...

Profit per unit at the floor...

Fees per unit at the floor...

Estimates only. Assumptions are listed below, and you can change every input.

Every repricing rule needs a floor: the price below which you would rather lose the sale than take it. Sellers who set that floor by feel either leave money on the table or, worse, follow a competitor into a race where every order loses money once fees and shipping are counted. The mistake is usually forgetting that marketplace and payment fees scale with price, so the true floor is higher than cost plus shipping.

This calculator takes your landed unit cost, outbound shipping and packaging, percentage fees on the sale price, any fixed per-order fee, and the minimum net margin you will accept. It solves for the break-even price where you earn nothing, and the floor price where you earn exactly your target margin after all costs. Because percentage fees depend on the sale price, both numbers are solved algebraically rather than by adding a markup to cost.

How to use this tool

Enter your landed cost per unit and the outbound shipping and packaging you absorb on a typical order.
Enter the percentage fees your marketplace and payment processor take, plus any fixed per-order fee. For your own store, set the marketplace fee to 0.
Set the minimum net margin you will accept and use the floor price as the hard lower limit in your repricing rule. The break-even price is the number you should never go below under any circumstances.

What the math assumes

Marketplace and payment fees are applied as a percentage of the item price only; if your platform also charges fees on shipping collected from the buyer, the true floor is slightly higher.
The target margin is net profit as a share of the sale price after all listed costs and fees, not a markup on cost.
Returns, chargebacks, advertising, storage, and overhead are not included; add an estimate to the landed cost if you want them covered by the floor.
If percentage fees plus target margin reach 100% or more, no price can satisfy them, and the floor is shown as 0.
Sales tax collected from the buyer is assumed to pass through and is not part of price or cost.

Frequently asked questions

Why is the floor price not just cost plus shipping plus my margin?

Because percentage fees grow with the price. Every dollar you add to the price to cover margin also adds fee dollars, so the tool solves price equals costs divided by (1 minus fee share minus margin share), which is higher than a simple markup.

Should my repricing floor be the break-even price or the floor at target margin?

Use the floor at your target margin as the working limit for your rule. The break-even price is only useful for clearance or when you are deliberately trading margin for inventory turnover, and even then you should know exactly what you are giving up.

How do I handle products where shipping varies by destination?

Use your average outbound cost per order, or run the calculator with your worst realistic shipping cost if you want a conservative floor. A floor that is safe for the expensive zones is safe everywhere.
