How to Calculate Your Shop's Real Profit

To find your shop's real profit, take your sales revenue, subtract the cost of the goods you actually sold (COGS), then subtract your expenses — what's left is net profit. Tukri is a mobile POS, inventory and reporting app for small shops in Bangladesh whose profit & loss report does this automatically, using a per-sale cost snapshot so the profit number is the true one, not a guess.

What is the real shop profit formula?

Profit has two layers: gross profit (what your goods earned over what they cost) and net profit (what's left after running the shop). Daily or monthly, the maths is the same — only the date range changes.

  • Gross profit = Revenue − Cost of goods sold (COGS)
  • Net profit = Gross profit − Expenses (rent, salary, bills)
  • Revenue = total sales, minus any returns
  • COGS = the cost YOU paid for the items that actually sold
  • Tukri's profit & loss report shows all four lines for any date range

Why does paper hide your true profit?

A notebook usually records cash in and cash out, not the cost of each item sold — so it shows money movement, not profit. The bigger trap is cost: the price you pay for stock changes over time, so today's purchase cost is not the cost of the item you sold three weeks ago.

  • Paper tracks cash flow, which is not the same as profit
  • Today's higher buying price overstates the cost of old stock you already sold
  • Discounts and returns quietly eat the margin you thought you made
  • Expenses paid weeks later get forgotten when you tally up

How does Tukri keep the profit number honest?

Every time you make a sale, Tukri freezes the actual cost of those exact items as a snapshot on the receipt — so profit is measured against the cost you really sold at, not whatever stock costs today. The profit & loss report then sums those snapshots into clean revenue, COGS, discount and expense lines.

  • Per-sale cost snapshot locks the true COGS at the moment of sale
  • Returns are netted out of revenue automatically
  • Expenses (with receipt photo) flow into the same report
  • Net profit = revenue − COGS − discounts − expenses, with no float drift
  • Top-products and stock-valuation reports show where the margin lives

When is a paper khata enough — and when not?

For a tiny stall with a handful of items and steady costs, a paper খাতা can give you a rough monthly sense. Once your buying prices move, you give credit (বাকি), or you run discounts, the paper number drifts from reality and a tool like Tukri earns its place.

  • Paper is fine for very low volume and stable costs
  • A tool helps once costs change month to month
  • Helpful when you sell on বাকি or run frequent ছাড়
  • Essential if you want a true number per day, not once a year

Frequently asked questions

How do I calculate my shop's daily profit?
Add up the day's sales (minus returns), subtract the cost of the goods that sold, then subtract that day's expenses — the remainder is your daily net profit. Tukri's profit & loss report produces this for any single day automatically.
Why is my real profit lower than my cash in the drawer?
Cash in the drawer is money movement, not profit — it ignores the cost of the stock you sold and the expenses still to be paid. Tukri separates revenue, cost of goods sold and expenses so you see real profit, not just cash.
What is COGS and why does it matter for shop profit?
COGS (cost of goods sold) is what you actually paid for the items that sold in a period, and profit is meaningless without it. Tukri snapshots the true cost on every sale, so COGS reflects what you really paid, not today's stock price.
Can Tukri calculate my monthly profit automatically?
Yes. Tukri's profit & loss report shows revenue, COGS, discounts, expenses and net profit for any date range, including a full month, using the cost snapshot recorded on each sale.
