Revenue is easy to see — profit is what actually keeps an online store alive. Enter your monthly numbers and this calculator walks from gross profit down to net profit after every major cost line: product cost, shipping, advertising, overhead and payment processing fees.
All sales before any costs.
Direct product + inbound shipping cost.
Outbound shipping, 3PL and packaging.
Software, staff, rent, fees not listed elsewhere.
Average rate charged by your payment provider.
Net profit
$5,120.00
Your store is profitable at these inputs. Track the net margin trend month over month rather than a single snapshot.
Net Profit = Revenue − COGS − Shipping − Ad Spend − Overhead − (Revenue × Fee %)
Anything directly tied to each unit sold: product purchase or manufacturing cost, inbound freight, duties, and unit-level packaging.
Most processors (Stripe, PayPal, Shopify Payments) charge a percentage of each sale plus a small fixed fee. Using your effective average rate keeps the estimate accurate without per-order data.
