Online Store Income
Running an online store means revenue per order minus the cost to make, ship, and sell each item. Margins are easy to overstate when fees and materials are ignored. These tools help you estimate profit per order and per month.

Frequently asked questions
How do I estimate online store profit?
For each order, subtract product, shipping, and fee costs from the sale price to get profit per order, then multiply by monthly volume. The profit and break-even calculators handle this from your numbers.
Why are my store margins thinner than expected?
Materials, shipping, packaging, and stacked fees each take a slice of every order. Estimating per-order net rather than revenue reveals the true margin.
How many orders do I need to break even?
Divide your fixed monthly costs by your profit per order. The break-even calculator estimates the order count that covers your costs.
