How to Read a Profit & Loss Account — A Business Owner's Guide

Why Most Business Owners Can't Read Their Own P&L

The Profit & Loss account is the most important financial document in your business. Most business owners receive one monthly from their accountant and look only at the bottom line. That's like reading only the final score of a cricket match — you have no idea how the game was played or what to change next time.

This guide walks through a typical P&L using Sunrise Retail (a fictional trading business) as an example. By the end, you'll know what every line means and what questions to ask.

The Structure of a P&L

A P&L has three main sections:

Revenue — what you earned

Cost of Goods Sold (COGS) — the direct cost of producing what you sold

Operating Expenses — overhead costs of running the business

Sunrise Retail — April P&L

Reading Each Section

Revenue

Gross sales minus returns and trade discounts. Always look at the trend: is revenue growing month-on-month? Is the returns figure growing — and if so, why?

Cost of Goods Sold

Opening stock + purchases − closing stock. This is the direct cost of what you sold this month. The key metric is Gross Margin (Gross Profit ÷ Net Revenue). For Sunrise Retail, 41.7% is healthy for a trading business. A declining gross margin signals pricing pressure or rising supplier costs.

Gross Profit

What's left after paying for the products you sold. This is the money available to pay all your business expenses and still have profit.

Operating Expenses

Every expense needed to run the business that isn't directly tied to production.

Salaries at ₹2,40,000 is the biggest expense. Is it growing? Is productivity growing with it? Rent at ₹85,000 is fixed. Is it a reasonable percentage of revenue (~4.7% here)? Marketing at ₹55,000 — are you tracking what return this generates? Bank charges and interest at ₹12,000 — is this growing? Rising interest costs may indicate over-reliance on credit.

Net Profit and Net Margin

₹2,88,000 on ₹18,18,000 revenue = 15.8% net margin. This is good for a retail trading business (typical range: 8–18%). But the number alone is meaningless without comparison to last month and last year.

Three Questions to Ask Every Month

1. What changed versus last month?

Comparing absolute numbers across months reveals trends. Revenue up 12% but net profit up only 3%? Expenses grew faster than revenue — investigate.

2. Are margins compressing?

If gross margin is shrinking (COGS is growing faster than revenue), either prices are being cut or purchase costs are rising. Both need a response.

3. What's driving the biggest expense line?

In Sunrise Retail's case, it's salaries. Is headcount growing? Is overtime being paid? Are productivity metrics supporting the spend?

What the P&L Doesn't Tell You

The P&L shows you performance — what you earned and spent. It does not tell you:

• Whether you have cash (that's the Cash Flow Statement)
• What you own and owe (that's the Balance Sheet)
• Whether your customers have paid (that's the Accounts Receivable Report)

All three statements together give you the complete picture.

Conclusion

Reading a P&L is a learnable skill. Once you know what each line means, you can have a much more productive conversation with your CA — and make better business decisions. If your accountant hasn't explained your P&L to you, ask them to. Or book a consultation with our team.
