Understanding Your Profitability: A Simple Guide for Small Business Owners

Profitability is the key to keeping your business alive and growing. Yet, many small business owners wait until the year's end to determine if they’ve made money. That’s a mistake.

Quick answer: how to check your small business profitability

Gross profit = revenue − direct job costs (labour, materials, subcontractors).
Net profit = gross profit − overhead (rent, vehicles, software, admin, marketing).
Net profit margin = net profit ÷ revenue × 100. For example, $60,000 ÷ $400,000 = 15%.
Check it every month on your Profit & Loss statement, not once a year at tax time.

If the margin is slipping, the fix is almost always in one of three places: costs, pricing or job efficiency, all covered below.

Regularly reviewing your financial data through a monthly financial review helps you make informed decisions about pricing, expenses, and operations—allowing you to proactively engage in profit margin management before it’s too late. Not sure where to start? We help small businesses gain clarity on their numbers and take action to boost profitability.

In this guide, we’ll break down how to understand your profitability, the key numbers you should track, and the steps you can take to improve your margins.

Understanding Your Small Business' Profitability

To understand your profitability, start by looking at three key financial figures:

Revenue (a.k.a. Income or Sales) – This is the money your customers pay you. Your top-line revenue represents the total amount of money flowing into your business before any expenses.
Expenses – This includes everything your business spends money on, from materials and subcontractors to insurance and marketing. Expenses are typically divided into categories:
- Direct Costs (Cost of Goods Sold - COGS): Labor, materials, and any costs directly related to completing a job.
- Overhead Costs: Things like rent, software subscriptions, admin salaries, and marketing.
Profit – The amount of money left after paying all expenses. This is the number that determines whether your business is financially healthy.

Your goal: Have more revenue than expenses to generate a profit.

How to Check Profitability Regularly (Not Just Annually!)

Many small business owners only assess profitability annually when taxes are prepared. But to truly manage small business profitability, it's crucial to perform a monthly financial review or quarterly at minimum.

Here’s how:

Use financial management software, like QuickBooks, to track revenue and expenses. QuickBooks can automatically generate Profit & Loss (P&L) reports to simplify understanding financial statements.
Work with a bookkeeper or accountant who can prepare these reports for you regularly.
Review your P&L statement and ask questions:
- Are my expenses growing faster than my revenue?
- What areas are eating into my profit?
- Is my pricing high enough to cover costs and leave room for profit?

By consistently engaging in a monthly financial review, you'll spot issues early and can proactively adjust your strategy.

Finding and Fixing Profitability Issues

If your business isn’t as profitable as you’d like, it’s time to dig into the numbers and figure out what’s eating away at your profit margin management. Here’s where to start:

1. Are your expenses too high?

Look at your biggest expense categories and ask yourself:

Subcontractor Costs: Are you outsourcing too much? Can you bring more work in-house?
Vehicle Costs: Are vehicle leases, maintenance, or fuel costs too high? Would a more fuel-efficient or electric vehicle help?
Material Costs: Are you buying in bulk for discounts? Are you using excess materials that could be better managed?
Admin & Software Expenses: Are you paying for software or services you don’t really need?

2. Are you charging enough?

If you’re great at what you do but still struggling to turn a profit, you may not be charging enough.

Look at your job pricing—does it fully cover your labour, materials, and overhead and leave room for a healthy profit?
Compare your rates with competitors. If you're offering premium service, your pricing should reflect that.
Consider small, incremental price increases rather than one big jump to avoid customer pushback.

3. Are you maximizing job efficiency?

Labour Efficiency: Are you using your team’s time wisely? Are jobs taking longer than they should?
Scheduling & Workflow: Are delays costing you money? Could better scheduling or automation tools help?
Upselling & Additional Services: Are you maximizing each job by offering complementary services to increase revenue per project?

The Bottom Line

Understanding your small business profitability isn’t about complicated accounting—it’s about regularly checking in on your numbers and making smart decisions to improve them.

If you wait until the end of the year to see if you made a profit, you’re already too late. By tracking revenue, expenses, and profit margins on a monthly or quarterly basis, you can adjust pricing, cut unnecessary costs, and ensure your business stays profitable.

Frequently Asked Questions

What is small business profitability?

Small business profitability is how much of your revenue you keep once every cost is paid. It's measured as net profit (revenue minus direct job costs minus overhead) and as net profit margin, which is net profit as a percentage of revenue. A business can be busy and growing and still be unprofitable if its pricing doesn't cover its costs.

How do I calculate my profit margin?

Divide net profit by revenue and multiply by 100. If you brought in $400,000 and had $60,000 left after all job costs and overhead, your net profit margin is 15%. For a single job, use that job's price minus its labour, materials and subcontractor costs to get the job's gross margin.

What solutions help small business owners calculate daily profit margins?

Accounting software like QuickBooks gives you a Profit & Loss report you can run any day. Job management software like Jobber or Tradify tracks costs against each job, so you can see margins job by job. For a single daily number, a simple tracker that pulls revenue and costs from those systems into one sheet works well; here's a real case study of a daily profit tracker built for a trades client.

How often should I check my business's profitability?

Monthly at minimum, and weekly if margins are thin or you're growing fast. Waiting until year-end means you find out about a pricing or cost problem months after you could have fixed it.
