How to read your monthly financial statements: a plain-English guide

A monthly financial statement pack is three documents working together. Each one answers a different question. This guide explains what each statement shows, which lines small business owners usually look at first, and how the three link up. It is information, not advice.

The three statements

• Income statement (also called profit and loss or P&L): revenue, cost of goods sold, operating expenses and net income for the period.
• Balance sheet: assets, liabilities and equity at a point in time.
• Cash flow statement: cash movements across operating, investing and financing activities.

The SEC’s beginner guide to financial statements describes each in the same order.

Income statement: did the business make a profit this month

Read from the top down.

1. Revenue (sometimes called sales or turnover). Total value of goods and services billed in the period. For accrual-basis books, revenue is recognized when earned, not when the cash arrives.
2. Cost of goods sold (COGS). Direct costs of what was sold — materials, direct labor, delivery.
3. Gross profit = Revenue − COGS. Gross margin = Gross profit ÷ Revenue.
4. Operating expenses. Rent, software, payroll for non-direct roles, marketing, professional fees.
5. Operating income = Gross profit − Operating expenses.
6. Other income and expenses, including interest and tax.
7. Net income (the bottom line).

Three questions to ask of the income statement:

• How does this month’s gross margin compare with the trailing three months? A sudden fall usually points to pricing, cost inflation or a product mix shift.
• Which operating expense line moved the most in absolute dollars?
• Does revenue track invoices actually sent, or does it include anything booked in error?

Balance sheet: what the business owns and owes right now

The balance sheet is a snapshot at a single date, usually the last day of the month. It is laid out in three sections.

Assets

• Current assets: cash and equivalents, accounts receivable (money customers owe), inventory, prepaid expenses.
• Non-current assets: property, equipment, software licenses capitalized and intangible assets.

Liabilities

• Current liabilities: accounts payable, credit card balances, short-term loans, payroll taxes due, sales tax payable, accrued expenses.
• Non-current liabilities: long-term loans, lease liabilities over one year.

Equity

Equity is the owners’ residual claim. It typically includes paid-in capital, retained earnings and current-year earnings. Equity equals total assets minus total liabilities — this identity has to balance.

Two ratios often read off the balance sheet

• Current ratio = Current assets ÷ Current liabilities. A measure of short-term solvency.
• Debtor days (also called days sales outstanding) = (Accounts receivable ÷ Revenue) × number of days in the period.

Cash flow statement: where did the cash go

Profit and cash are not the same number. The cash flow statement reconciles the two across three sections.

1. Operating activities: cash from running the business — collections from customers, payments to suppliers and staff, interest and tax paid.
2. Investing activities: cash used to buy or sell long-term assets.
3. Financing activities: cash from or to lenders and owners — new loans, loan repayments, owner distributions, equity raises.

Added together, these three sections explain the change in the cash balance from one month to the next.

Reading the three together

1. Start with the income statement to answer “did we make a profit this month”.
2. Move to the cash flow statement to answer “did the profit become cash”.
3. End with the balance sheet to see what the month left behind — receivables, inventory, debt and cash balance.

If profit is up but cash is down, the usual culprits are accounts receivable rising faster than sales, inventory building up, or loan repayments and owner draws drawing cash out below the operating line.

Illustrative example

A small services business reports (illustrative round figures only): revenue $80,000, COGS $20,000, operating expenses $45,000, net income $15,000. The balance sheet shows accounts receivable rising from $25,000 to $45,000 over the month and cash falling by $5,000. The cash flow statement explains the gap: $15,000 of profit, less a $20,000 build-up in receivables, equals $5,000 of operating cash out. The month’s profit sat in customer invoices rather than the bank.
