03 / PRACTICAL GUIDE
A store can generate revenue and still lose money when advertising costs, fees and shipping are overlooked.
Profit = selling price − product − shipping − other costs − ads − fees
Profit margin is profit divided by selling price. Use prices before taxes for consistent estimates; check the tax rules that apply to you.
If an item costs $10 and sells for $15, markup is 50% but profit margin is 33.3%.
To calculate a target selling price, divide your costs by 1 − fee% − target margin%, including fixed transaction fees in your costs first.
Divide monthly fixed costs by the contribution per order and round up.
This estimates the orders needed to cover fixed costs. It does not predict traffic or sales.
