Shop Profit Calculator

Enter your sales and costs to find out your real profit. You will get gross profit, net profit, profit margin, daily average profit and a break-even estimate.

Practical tips for small shopkeepers

1. Track the cost of goods separately from expenses. Rent, staff pay and utility bills are fixed — if you mix them with stock cost, you will never know your true margin.
2. Watch the daily average profit, not just total sales. High sales with a thin margin can still leave you with almost nothing at the end of the month.
3. Use the break-even number as your daily target. If your daily sales are below it, you are losing money — cut a cost or raise a price before the month ends.

How to use

1. Enter total sales for the period, the cost of the goods you sold, and your operating expenses.
2. Set the number of days the figures cover (30 for a month, 7 for a week).
3. Press "Calculate Profit" to see gross profit, net profit, margin, daily average and break-even.
