Why you need to read these documents yourself

An accountant does their job correctly when they record and classify your business's transactions. But their role is technical, not strategic. Interpreting what those numbers mean for the future of your company — that's your responsibility as the owner.¹

The three basic financial statements are the income statement, the balance sheet and the cash flow statement. Each one answers a different, fundamental question. Together they tell the complete financial story of your business.

67% of SME owners don't review financial statements monthly²

3x more likely to survive if the owner understands their finances³

1 hour per month is enough to review all three with real understanding

Income statement: making or losing money?

The income statement — also called the P&L (profit and loss statement) — shows your revenue, costs and expenses during a given period (a month, quarter or year) and concludes with net profit or loss.⁴

Its structure is simple: it starts with revenue from sales, subtracts the cost of goods sold to get gross profit, then subtracts operating expenses to reach operating income, and finally deducts taxes and interest to arrive at net income.

Basic income statement structure

Revenue − Cost of goods sold = Gross profit − Operating expenses (payroll, rent, marketing) = EBITDA / Operating income − Interest & taxes = Net income

What to review every month

More than the final number, what matters is the trend and the composition. Three key questions: Are revenues growing? Is the gross margin (gross profit / revenue) stable or deteriorating? Are operating expenses growing faster than revenue?

A gross margin that compresses month after month is an early warning sign: either your production costs are rising or you're selling cheaper without realizing it. You need that information in real time, not at the year-end meeting.

Item	Current month	Previous month	Change
Revenue	$450,000	$400,000	+12.5%
Cost of goods sold	$225,000	$180,000	+25.0% ⚠️
Gross profit	$225,000	$220,000	+2.3%
Gross margin	50%	55%	−5pp ⚠️
Operating expenses	$150,000	$140,000	+7.1%
Net income	$75,000	$80,000	−6.3% ⚠️

In this example, sales grew 12.5% but net income fell 6.3%. The culprit is the cost of goods sold, which grew at double the speed of revenues. Without reading the income statement in detail, an owner might celebrate the growth without noticing the business is becoming less profitable.

Balance sheet: what do you own and owe?

The balance sheet is a snapshot of the business's financial health at a specific moment. It shows three things: what the business owns (assets), what it owes (liabilities) and what's left for the owners (equity).⁵

The fundamental accounting equation is inviolable: Assets = Liabilities + Equity. Always. If it doesn't balance, there's an error.

Assets

All resources the business controls. Divided into current (cash, receivables, inventory — everything convertible to money within a year) and non-current (machinery, property, equipment, intangibles). The liquidity of your assets matters as much as their value.

Liabilities

All the business's obligations. Current are those due within a year (accounts payable to suppliers, short-term debt). Non-current are long-term (mortgages, investment loans). The ratio between current assets and current liabilities — called the current ratio — tells you whether the business can pay its immediate debts.⁴

Current ratio: the basic liquidity indicator

Current ratio = Current assets ÷ Current liabilities. A value above 1.0 means the business has more liquid assets than short-term debt. The healthy range for most SMEs is between 1.5 and 2.5. Below 1.0 is risk territory — the business may not be able to meet short-term obligations.

Equity

What's left for the owners after deducting all liabilities. Equity growing consistently over time — funded by retained earnings, not more debt — is the clearest signal the business is generating real value.

Cash flow statement: do you have real money?

We covered this in detail in the cash flow article, but in the context of the three financial statements it's important to understand why it exists as a separate document: because the income statement works on an accrual basis, not a cash basis.⁶

This means the income statement records revenue when invoiced, not when collected. A business can show $500,000 in monthly sales, have positive net income, and at the same time have $0 in the bank because those sales haven't been collected yet.

The cash flow statement is the only one that shows actual cash movement. It's the antidote to accrual accounting.

How to read them together

Each financial statement tells part of the story. Reading them together gives you the complete picture:

Profitable in P&L + negative cash flow → Business sells well but collects slowly. Receivables management and cash conversion cycle problem.
Positive cash flow + heavily indebted balance sheet → Business generates operating cash but has debt that could become unsustainable if conditions change.
Positive net income + declining equity → May indicate owners are withdrawing more than the business generates, or there are accumulated losses from prior periods.
All three positive → Profitable, solid assets and generating real cash. This is the combination you're looking for.

"Financial statements are like a cockpit dashboard. You don't need to be a pilot to understand that when a red light turns on, something needs attention." — Aswath Damodaran, The Little Book of Valuation (2011)

Where to start

If you've never formally reviewed your business's financial statements, the best starting point is to ask your accountant for last quarter's statements and sit with them for an hour with three questions in mind: Am I making or losing money? Do I own more than I owe? Is my operating cash flow positive?

Over time, add depth: margins, liquidity ratios, month-by-month trends. But the foundation is that: three documents, three questions, one hour a month. It's the most valuable financial habit you can build as a business owner.

Inflation and personal finance: the impact nobody calculates

The real cost of having money "saved"

Suppose you have $10,000 in a savings account yielding 4% annually, in an 8% inflation environment. In nominal terms, after one year you have $10,400. But in real terms — what you can actually buy with that money — you've lost approximately 3.7% of your purchasing power. That's roughly $370 of buying power that vanished without anyone taking it directly.

Scenario	Initial capital	Nominal return	Inflation	Real value in 5 years
Checking account (0%)	$10,000	0%	7%	$7,130
Traditional savings (4%)	$10,000	4%	7%	$8,600
Term deposit (5%)	$10,000	5%	7%	$9,015
Index ETF (~15% nominal)	$10,000	15%	7%	$14,860

Differentiated inflation: not everything rises equally

Inflation isn't uniform across categories. During inflationary periods, food and energy tend to rise faster than the general index, while durable goods and technology may stay flat or fall. Households spending 30-40% of income on food experience inflation much more severely than headline numbers suggest.

The hard-currency diversification case

In many emerging market countries, historical experience with inflation, devaluation and monetary crises has made diversifying savings into USD, EUR or other hard currencies a rational hedge — not a speculative act. Economists like José Antonio Ocampo and Guillermo Calvo have documented how self-reinforcing inflationary spirals develop and why protecting part of your wealth from local currency risk has historically been prudent in high-inflation environments.
