How to Read a Profit & Loss Statement in Under 5 Minutes

Most business owners have seen a Profit & Loss statement—but very few actually use it.
The truth is, your P&L is one of the simplest and most powerful tools for understanding what’s going on in your business.

And you can learn to read it in under five minutes.

This guide breaks down exactly what to look for so you can stop guessing about your performance and start making decisions based on real numbers.

1. Start With Your Revenue

At the top of your P&L is your Total Income (sometimes called Gross Revenue or Sales).

Ask yourself:

• Did revenue go up or down compared to last month?

• Compared to this time last year?

• Were there any spikes or dips? Why?

You always want to look at revenue first because it sets the context for everything else.

2. Review Your Cost of Goods Sold (COGS)

COGS only applies if your business sells physical products or provides services with direct, measurable costs (like subcontractors, supplies, or materials).

This tells you what it costs to deliver what you sell.

Key question:

• Are your direct costs rising faster than your prices?

That’s a red flag.

3. Calculate Your Gross Profit

This is where things get interesting.

Gross Profit = Revenue – COGS
Gross Margin = (Gross Profit ÷ Revenue)

Gross margin shows how profitable your core offerings are.

Margins vary greatly by industry, but rules of thumb:

• Strong margin: 60–90%

• Moderate margin: 40–60%

• Low margin: under 40% (you may be underpricing)

If your gross margin is too low, adjusting price or improving efficiency is more effective than increasing marketing.

4. Review Your Operating Expenses

These are the costs required to run your business, such as:

• software

• office supplies

• advertising

• payroll

• rent

• education

• insurance

Look for:

• categories that spike unexpectedly

• subscriptions you no longer use (these really add up!)

• expenses that don’t align with your goals

• categories that should be reduced or renegotiated

Your expenses reveal your habits—and your opportunities.

5. Look at Your Net Profit (Bottom Line)

This is the number that matters most for your long-term health.

Net Profit = Revenue – All Expenses

Questions to ask:

• Are you profitable?

• If not, what specifically caused the loss?

• If yes, is the profit consistent?

• Is revenue too low—or are expenses too high?

Your net profit tells you whether the business is supporting your goals—or draining them.

6. Compare Month-Over-Month Trends

A single month doesn’t tell you much. Trends do.

Look at:

• revenue trends

• margin trends

• expense patterns

• consistent slow months

• high-demand seasons

This helps you make smarter decisions about pricing, marketing, staffing, and savings.

7. Keep It Simple

Don’t overanalyze.
Don’t complicate it.
Don’t chase numbers that don’t matter.

Start with:

• Revenue

• Gross Margin

• Total Expenses

• Net Profit

Those four numbers give you the clearest snapshot of your business health.
