Track Sales and Expenses

Record sales and expenses every week during a project so that profit or loss can be calculated accurately — and problems identified early.

In this lesson

Track Sales and Expenses is part of Planning a Small Money Project. This preview shows how project-money connects to everyday family decisions such as earning, saving, spending choices, goals, approvals, or parent-guided money conversations inside Progress Penguin.

Think about this money choice

Emeka runs a small car-wash service on Saturdays. By the end of the month he is not sure whether he made a profit.

How it works

To know whether a project made a profit, you must track what came in and what went out every week. Without records, you cannot tell at the end whether the project succeeded, where money was spent, or how to improve next time. Weekly records also show problems early — before they become losses.

Try a real-life example

Real-life money moment: Emeka runs a car-wash service on Saturdays. Week 1: earned 1800 in local currency, spent 600 in local currency on supplies. Week 2: earned 2100 in local currency, spent 750 in local currency. Week 3: earned 900 in local currency, spent 600 in local currency — an unusually slow week. Because he recorded weekly, he notices the drop and investigates before Week 4.

Quiz preview

Tracking Sales and Expenses during a project means:

Only recording sales since expenses were already listed before starting

Recording every item sold and every cost paid as they happen

Asking a parent to monitor the money since tracking is complex

Counting total sales at the end of the project and subtracting guessed costs

You sold 8 bracelets at 500 in local currency each and spent 1200 in local currency on extra supplies. Your net this week is:

3200 in local currency — deducting 800 in local currency as an estimated average cost

1200 in local currency — the expenses represent your true earnings from this week

4000 in local currency — total sales without subtracting any additional costs

2800 in local currency — sales of 4000 in local currency minus 1200 in local currency expenses
