Reading a profit and loss statement when you never studied accounting
A profit and loss statement answers one main question: during a chosen period, did the business earn more than it spent to earn that revenue? It starts with sales, subtracts the cost of what was sold, then subtracts operating expenses. The result is profit or loss for that period. It is not the same as the cash in the drawer or bank.
You can read a P&L without accounting education if you follow the rows in order and compare like periods. The important discipline is classifying transactions correctly. Udhar sales, stock purchases, owner withdrawals and loan money can make a report confusing when they are treated as the same thing.
Start with the reporting period and sales
Check the dates first. A monthly P&L should contain activity from that month, not whatever has been paid by customers so far. A credit sale made in July can count as July revenue under an accrual approach even if money arrives in August. A cash-based report may treat timing differently. Know which method your accountant or system uses and do not mix methods casually.
Sales should be net of genuine returns and discounts according to the chosen method. Money borrowed from a bank is not sales. Capital introduced by the owner is not sales. An old customer paying an udhar balance creates cash today but does not create a second sale if the original sale was already counted.
Break sales into useful groups only when the information helps: grocery, dairy, personal care, services or wholesale. Too many categories make the report hard to maintain; one total hides where performance changed.
Understand cost of goods sold
Cost of goods sold, often called COGS, is the cost of the inventory actually sold during the period. It is not always equal to all stock purchases made that month. If you buy ₹50,000 of goods but ₹15,000 remains on the shelf, treating the full ₹50,000 as the cost of current sales understates profit.
A common formula is opening inventory + purchases − closing inventory = cost of goods sold, adjusted for returns and other relevant movements. A service business may instead track direct materials or labour connected to delivering the service.
Stock used by the owner’s household, damaged goods and theft should be recorded clearly. If they disappear from inventory without a reason, the margin looks worse but the report does not explain why.
Worked example: a monthly kirana P&L
For July, Mayur Kirana records:
- Net sales: ₹2,40,000
- Opening inventory: ₹90,000
- Purchases: ₹1,75,000
- Closing inventory: ₹1,05,000
Cost of goods sold is ₹90,000 + ₹1,75,000 − ₹1,05,000 = ₹1,60,000.
Gross profit is ₹2,40,000 − ₹1,60,000 = ₹80,000.
Operating expenses are:
- Rent: ₹18,000
- Salaries: ₹22,000
- Electricity: ₹5,500
- Delivery and transport: ₹3,500
- Repairs and supplies: ₹2,000
- Payment and bank charges: ₹1,000
Total operating expenses are ₹52,000. Net operating profit in this simplified example is ₹80,000 − ₹52,000 = ₹28,000.
The owner withdrew ₹20,000 for household expenses. That withdrawal reduces business cash but is not automatically an operating expense. If it were incorrectly added to expenses, reported profit would fall to ₹8,000 even though the business operations earned ₹28,000. This distinction is why cash and profit differ.
Tax, interest, depreciation and exceptional items may appear below operating profit depending on the report. Ask a qualified accountant how they apply to your business.
Read gross profit before net profit
Gross profit shows what remains after the direct cost of goods sold. If sales rise but gross profit percentage falls, discounting, product mix, purchase prices, wastage or missing stock may be the cause. Operating expenses have not yet entered the calculation.
Net profit shows what remains after regular business expenses. A strong gross profit can disappear under high rent, salaries, transport or financing costs. Conversely, cutting a necessary expense may improve one month but harm service or stock availability later.
Compare both the rupee amount and percentage. ₹80,000 gross profit on ₹2,40,000 sales is about one-third of sales in the simplified example. If last month had the same sales but ₹65,000 gross profit, investigate purchase cost, selling prices and stock loss.
Why profit does not equal cash
Several timing differences separate profit from cash. Udhar sales can increase profit before collection. Buying inventory uses cash before all of it becomes cost of goods sold. A loan adds cash without adding profit. Repaying loan principal uses cash without being a normal P&L expense, while interest may be an expense. Buying equipment uses cash but may be recognised over time.
That means a profitable shop can still struggle to pay suppliers if customers owe too much or too much cash is tied in slow stock. A loss-making shop can temporarily have cash after borrowing or delaying bills.
Read the P&L alongside a cash summary, customer balances, supplier obligations and inventory. One report never tells the complete story.
Check for classification mistakes
Before trusting the result, look for large or unusual rows. Confirm that household purchases are not business expenses, that stock purchases are not all counted twice, and that customer collections are not recorded as new sales. Check cancelled invoices, duplicate entries and payment-mode mistakes.
Compare totals with independent evidence: sales register, expense bills, inventory count, bank statement and cash closing. Exact agreement may require accounting adjustments, but unexplained differences deserve attention.
Use consistent categories month to month. If transport moves between “purchase,” “delivery” and “other,” trend comparisons become weak. A short category list with clear rules is better than perfect detail one month and chaos the next.
Use the statement to make decisions
Ask three questions:
- Which sales category contributed more or less than last period?
- Did gross margin change, and why?
- Which operating expense changed enough to need action?
Do not react to every small variation. Electricity may rise seasonally. Festival purchases can affect stock timing. Compare with the same season where possible and write reasons for major changes.
Turn findings into one or two actions: renegotiate a supplier line, adjust a clearly underpriced item, reduce spoilage, collect overdue udhar or review a recurring expense. A P&L is useful when it changes a decision, not when it is filed unread.
Practical takeaway
Read a P&L from top to bottom: verify the period, check net sales, calculate cost of goods sold, examine gross profit, then subtract operating expenses to reach net profit. Keep owner withdrawals, loans and old-customer collections out of sales or expenses unless proper accounting treatment says otherwise.
Recreate the worked example with your last month’s numbers and note every estimate. Improve the weakest estimate first, usually closing stock or missing expenses. Then use gross margin versus net margin and markup versus margin to interpret pricing more accurately.
