The Formula

Net Profit:

Net Profit = Total Revenue − Total Expenses

Net Profit Margin:

Net Profit Margin % = (Net Profit ÷ Revenue) × 100

Example: A small business has $150,000 in quarterly revenue with these expenses:

  • COGS: $52,500 (35% of revenue)
  • Operating Expenses: $37,500 (25%)
  • Marketing: $15,000 (10%)
  • Admin: $12,000 (8%)
  • Other: $3,000 (2%)
  • Total Expenses: $120,000
  • Net Profit: $150,000 − $120,000 = $30,000
  • Net Profit Margin: $30,000 ÷ $150,000 = 20%

Net Profit vs. Gross Profit

Many business owners confuse these two metrics. Here is the difference:

  • Gross Profit = Revenue − COGS. This tells you how much you make after covering the direct costs of your products or services. It measures production and sourcing efficiency.
  • Net Profit = Revenue − All Expenses. This is the true bottom line — what is left after every single cost is accounted for, including rent, salaries, marketing, insurance, taxes, and interest.

A business can have a strong gross profit margin but a weak net profit margin if operating expenses are too high. For example, a restaurant with 65% gross margins might only have 5% net margins after paying for rent, labor, utilities, and marketing.

Key takeaway: Gross profit tells you if your products are priced right. Net profit tells you if your entire business model works.

Net Profit Margins by Industry

IndustryTypical Net Profit MarginNotes
Software / SaaS15–30%Low marginal costs after development
Professional services15–25%Consulting, accounting, legal
Healthcare / dental10–20%Varies by specialty
E-commerce5–15%Depends on product category
Retail (general)3–10%Thin margins, high volume
Restaurant3–9%Labor and food costs dominate
Manufacturing5–12%Materials and overhead intensive
Construction3–8%Project-based, variable costs
Grocery / supermarket1–3%Very high volume, very thin margins

If your net profit margin is significantly below the industry average, examine your expense categories to find where costs are out of line.

How to Improve Your Net Profit

Cut costs strategically:

  • Negotiate better rates with suppliers and vendors
  • Automate repetitive tasks to reduce labor costs
  • Eliminate subscriptions and services you no longer use
  • Review insurance policies annually for better rates
  • Reduce waste in production and operations

Grow revenue efficiently:

  • Raise prices — even small increases (3–5%) compound significantly
  • Upsell and cross-sell to existing customers
  • Focus marketing spend on the channels with the best ROI
  • Improve customer retention — acquiring new customers costs 5–7x more than keeping existing ones
  • Expand into complementary products or services

Optimize operations:

  • Track expenses by category monthly to spot trends early
  • Set target margins for each expense category and hold teams accountable
  • Use this calculator regularly to measure progress toward profitability goals

Frequently Asked Questions

What is net profit?
Net profit (also called net income or the bottom line) is the amount of money left after you subtract all business expenses from your total revenue. It includes cost of goods sold, operating expenses, marketing, administrative costs, taxes, and interest. Net profit tells you how much your business actually earns.
Net Profit = Total Revenue − Total Expenses. Add up all your expenses (COGS, operating costs, marketing, admin, taxes, etc.) and subtract that total from your revenue. The result is your net profit for the period.
A good net profit margin varies by industry. Generally, 5% is considered low, 10% is average, and 20% or above is considered excellent. Service businesses often achieve higher margins (15–30%) while retail and manufacturing typically see lower margins (3–10%).
Gross profit is revenue minus cost of goods sold (COGS) only. Net profit is revenue minus all expenses — including COGS, operating expenses, marketing, admin, taxes, and interest. Gross profit measures production efficiency; net profit measures overall business profitability.
Yes. A negative net profit means your total expenses exceed your revenue — your business is operating at a loss. This is common for startups and businesses in growth phases, but sustained negative net profit is a warning sign that requires immediate attention to costs or revenue strategy.
There are two paths: increase revenue or reduce expenses. On the revenue side, raise prices, upsell, or expand to new markets. On the expense side, negotiate with suppliers, reduce waste, automate manual processes, and cut non-essential spending. Most businesses benefit from working on both simultaneously.
At minimum, calculate net profit monthly. Many successful small businesses track it weekly. Frequent monitoring helps you spot trends early — if margins are declining, you can take corrective action before a small issue becomes a crisis.
No. Net profit is an accounting metric that includes non-cash items like depreciation and accounts receivable. Cash flow measures the actual money moving through your bank account. A business can be profitable on paper but still have cash flow problems if customers pay late or inventory ties up cash.
