Gross Cost = Product Cost + Shipping + Tax + Fees
Net Cost = Gross Cost − Discount
Cost Per Unit = Net Cost ÷ Units
Selling Price Per Unit = Cost Per Unit × (1 + Markup %)
Contribution Margin Per Unit = Selling Price Per Unit − Variable Cost Per Unit
Contribution Margin Ratio = Contribution Margin Per Unit ÷ Selling Price Per Unit × 100
Break Even Units = Fixed Costs ÷ Contribution Margin Per Unit
These formulas help ecommerce sellers compare real unit costs, target pricing, and margin efficiency before publishing or changing a listing.
Find total net cost first, divide by total units, then apply the markup percentage. Selling price per unit = cost per unit × (1 + markup rate).
It equals the market price determined by industry-wide supply and demand. Individual sellers usually accept that price rather than control it.
Total consumer surplus will usually increase, because buyers pay less than before and more buyers may enter the market.
It is the contribution margin ratio. Formula: contribution margin per unit ÷ selling price per unit × 100.
That difference is the contribution margin per unit. It shows how much each sale contributes toward fixed costs and profit.
Total price = 9 × 1.92 = $17.28.
The break-even point will usually decrease, assuming variable cost per unit and fixed costs stay unchanged.
Price per unit is the amount charged or paid for one item, one pack, one kilogram, one gallon, or another standard unit. It helps compare products fairly.
Unit pricing reveals real profitability after fees, shipping, and discounts. It helps sellers avoid underpricing products that appear profitable only at the bundle level.
No. Cost per unit measures what one unit costs the seller. Selling price per unit is what the customer pays after markup or pricing strategy is applied.
The calculator limits net cost to zero for stability. In real business cases, that situation usually means an input mistake or an extreme promotional subsidy.
Yes. Enter a competitor unit price to see the price gap and percentage difference. That helps position your listing higher, lower, or near market averages.
It is the percentage of each sale left after variable costs. A higher ratio usually means more money remains to cover fixed costs and generate profit.
Markup is based on cost, while margin is based on selling price. They are related, but they are not the same percentage.
Use break-even units when planning launches, ad budgets, or price changes. It shows how many units must sell before the business starts earning profit.
