Profit and loss statement

What a profit and loss statement is

A profit and loss statement, often called a P&L or income statement, shows a company's revenues and expenses over a period of time. It answers one simple question: did the business make money or lose money during that period?

You can prepare a P&L for a month, a quarter, or a year. It is one of the main financial statements used by owners, managers, investors, and lenders.

Main parts of a P&L

A P&L has a few standard lines. Each line tells you something important.

• Revenue or sales: Money earned from selling goods or services.
• Cost of goods sold (COGS): The direct cost to make the product or deliver the service. For a retailer, this is the cost paid to suppliers.
• Gross profit: Revenue minus COGS. This shows how much money is left to cover other costs.
• Operating expenses: Day to day costs like rent, wages, marketing, utilities, and office supplies.
• Operating profit: Gross profit minus operating expenses. Also called operating income.
• Other income and expenses: Interest received, interest paid, gains or losses from selling assets.
• Taxes: Amount owed to the tax authorities.
• Net profit: The final number. Operating profit plus other income minus other expenses and taxes. This is what the business keeps or loses.

Two common formats

Single-step P&L:

• Lists revenues and gains together.
• Lists expenses and losses together.
• Subtracts total expenses from total revenues to get net profit. This format is simple but gives less detail.

Multi-step P&L:

• Shows gross profit, operating profit, and net profit in separate steps.
• Gives more insight into where profits come from. Most businesses use the multi-step format because it is easier to analyze.

Simple example

Numbers are for one month.

Revenue: $20,000
COGS: $8,000
Gross profit: $12,000

Operating expenses:

• Rent: $2,000
• Wages: $3,000
• Marketing: $500
• Utilities and other: $500 Total operating expenses: $6,000

Operating profit: $12,000 - $6,000 = $6,000

Other expenses:

• Interest: $200

Profit before tax: $5,800
Taxes: $1,160 (20%)
Net profit: $4,640

This result shows the business made $4,640 that month after all costs and taxes.

Key ratios to check

Ratios help you compare performance over time or versus other companies.

• Gross margin = Gross profit / Revenue. Shows how well a business controls production costs.
• Operating margin = Operating profit / Revenue. Shows how well the business controls operating costs.
• Net margin = Net profit / Revenue. Shows the final profit for each dollar of sales.
• EBITDA = Earnings before interest, taxes, depreciation, and amortization. Useful to compare companies with different tax or depreciation rules.

Simple example from above:

• Gross margin = 12,000 / 20,000 = 60%
• Operating margin = 6,000 / 20,000 = 30%
• Net margin = 4,640 / 20,000 = 23.2%

Accrual vs cash basis

A P&L can be prepared in two ways:

• Cash basis: Record income when cash arrives and expenses when cash is paid. Simpler, often used by very small businesses.
• Accrual basis: Record income when it is earned and expenses when they are incurred, even if cash moves later. This gives a clearer view of business performance.

Most larger businesses use accrual accounting.

Why the P&L matters

• Shows if the business is profitable.
• Reveals where money is earned and where it is spent.
• Helps set prices and control costs.
• Helps plan budgets and forecasts.
• Important for lenders and investors when deciding to fund a business.

How to read a P&L quickly

1. Look at revenue trend: Is revenue growing or shrinking?
2. Check gross margin: Are production or purchase costs rising?
3. Check operating expenses: Which expenses are growing fastest?
4. Compare operating profit to prior periods: Is core business getting better?
5. Check net profit and any unusual items: One-time gains or losses can hide the true trend.

What to do with the P&L

• If margins are falling, check COGS and pricing.
• If operating costs are rising, review staff, rent, and marketing effectiveness.
• Use the P&L with the balance sheet and cash flow statement to get the full picture.

A profit and loss statement is not complicated. It is a story told in numbers. Read it often. It tells you if the business is healthy or if something needs to change.
