Your P&L (profit and loss statement, also called an income statement) is the most important financial report your business produces. Here's how to actually read and use it.
The basic structure
The number most owners ignore: gross margin
Gross profit margin is your revenue minus your direct costs, expressed as a percentage. A 60% gross margin means for every $1 in revenue, you keep $0.60 before overhead. This is the most important indicator of your business model's health — and it's often buried below the top line where owners don't look.
If your gross margin is shrinking month over month, your prices may not be keeping up with your costs — even if your total revenue is growing. This is the kind of insight a monthly P&L review surfaces immediately.
How to use your P&L month over month
- Compare this month to last month: are expenses growing faster than revenue?
- Compare to the same month last year: is the business growing year over year?
- Look at each expense line: are there costs that have crept up without explanation?
- Check your gross margin: is it stable, improving, or declining?
What a good P&L review looks like
At Graphene, every Growth Package and CFO Lite client receives a monthly Loom video walkthrough of their P&L — not just a PDF. Adan walks through what changed, what to watch, and what it means for your business decisions. That's the difference between having financial reports and actually using them.
Common P&L mistakes to avoid
- Recording owner draws as expenses (they're not — they're equity withdrawals)
- Mixing personal expenses with business expenses
- Not separating COGS from operating expenses — this hides your real margin
- Not reviewing your P&L until tax season
