Formula Used
- Discounted Unit Price = Selling Price × (1 − Discount Rate)
- Returned Units = Units Sold × Return Rate
- Kept Units = Units Sold − Returned Units
- Net Item Sales = (Units Sold × Discounted Unit Price) − (Returned Units × Discounted Unit Price)
- Shipping Revenue = Kept Units × Shipping Charged to Customer
- Customer Revenue Excluding Tax = Net Item Sales + Shipping Revenue
- Inventory Loss on Returns = Returned Units × Cost Price × (1 − Recovery Rate)
- Effective COGS = (Kept Units × Cost Price) + Inventory Loss on Returns
- Marketplace Fees = Customer Revenue Excluding Tax × Marketplace Fee Rate
- Payment Processing = (Customer Revenue Excluding Tax × Payment Fee Rate) + (Units Sold × Fixed Payment Fee)
- Variable Costs = COGS + Shipping + Packaging + Handling + Marketplace Fees + Payment Fees + Return Processing
- Total Costs = Variable Costs + Advertising Spend + Fixed Overhead + Miscellaneous Costs
- Net Profit = Customer Revenue Excluding Tax − Total Costs
- Net Margin = Net Profit ÷ Customer Revenue Excluding Tax × 100
- Break-Even Units = Fixed Costs ÷ Contribution per Sold Unit

Frequently Asked Questions
1) What does this retail profit calculator measure?
It estimates net profit from retail sales after discounts, returns, shipping, packaging, fulfillment, marketplace fees, payment processing, ads, and overhead. It also shows margin, markup, contribution, and break-even units for stronger decision-making.
2) Why is return recovery included?
Not every returned unit becomes a full loss. Some items can be restocked or resold. Recovery rate lets you model how much unit cost is recovered after returns, making profit estimates more realistic.
3) Is sales tax counted as profit?
No. This page shows estimated sales tax separately for planning visibility. Profit is based on revenue excluding collected tax, because that cash is usually remitted rather than retained.
4) What is the difference between margin and markup?
Margin compares profit to revenue. Markup compares selling price to cost. Both matter, but margin is usually better for evaluating overall business performance and profit quality.
5) Can I use this for marketplace stores?
Yes. The calculator includes marketplace commission and payment processing fields, which makes it useful for multichannel stores, marketplaces, social selling, and direct storefront operations.
6) What does break-even units mean?
Break-even units estimate how many sold units are needed to cover fixed costs based on expected contribution per sold unit. If contribution is negative, break-even is not achievable under current assumptions.
7) Can I analyze a monthly or campaign period?
Yes. Enter totals for any consistent period, such as one month, one promotion, or one product launch. Just make sure all revenue and cost inputs belong to the same timeframe.
8) Why export CSV and PDF reports?
CSV helps you move summary data into spreadsheets and dashboards. PDF is useful for sharing a fixed report with teammates, clients, finance reviewers, or operational stakeholders.
