Sold Quantity = Quantity Bought − Returned Or Unsold Quantity
Revenue = (Selling Price × Sold Quantity) − Total Discount
Total Cost = Cost Price × Sold Quantity
Gross Profit = Revenue − Total Cost
Net Profit = Gross Profit − Extra Expenses
Profit Per Item = Net Profit ÷ Sold Quantity
Profit Margin = (Net Profit ÷ Revenue) × 100
Markup = (Net Profit ÷ Total Cost) × 100
This journal uses net profit because real selling records often include discounts, returns, and small business expenses.
A profit journal helps students connect money words with real numbers. Each row shows what was bought, what was sold, and what remained after costs. This makes classroom trading projects easier to understand. It also teaches careful record keeping.
Many children learn profit best when they repeat the same steps. They enter prices, check quantity, subtract returns, and compare revenue with cost. The journal format turns one answer into a full history. That history helps students spot patterns and improve decisions.
This page also includes discounts and extra expenses. Those two fields show that selling is not only about price tags. Small changes can raise or lower net profit. Students can test ideas and see how each value changes the final result.
Teachers can use the example table during lessons. Students can copy the model, then enter their own classroom shop data. The chart gives a quick visual summary, while the export tools help save work for homework, sharing, or printed review.
Profit is the money left after costs and extra expenses are removed from revenue. If the answer is negative, it becomes a loss.
Returned or unsold items should not count as sold items. This keeps revenue and profit numbers more accurate in the journal.
Revenue is the money collected from sold items before subtracting cost and extra expenses. In this page, discounts are removed from revenue too.
Gross profit subtracts only item cost from revenue. Net profit subtracts item cost and extra expenses, so it gives a fuller business result.
Profit margin shows how much profit came from each revenue amount. It helps compare entries even when sales totals are different.
Yes. The layout fits school shop practice, math journals, and simple finance activities. It records each item clearly and keeps totals together.
Saving many entries creates a full journal. That makes it easier to compare products, days, and results across a larger activity.
A zero result means break-even. The selling activity earned enough to cover cost and extra expenses, but it did not create added profit.
