What is a good profit margin for a small US business?

A gross margin of 40–60% is considered healthy for most US small businesses. Net profit margins of 10–20% are excellent — the US average across industries is 7–10%.

How do I calculate selling price from a desired margin?

Use the formula: Selling Price = Cost ÷ (1 − Desired Margin %/100). For a $60 cost and 40% target margin: $60 ÷ 0.60 = $100.

Is gross profit the same as net profit?

No. Gross profit is revenue minus direct costs (COGS) only. Net profit is revenue minus all costs including operating expenses like rent, salaries, marketing, and taxes.

What is COGS and what does it include?

COGS (Cost of Goods Sold) includes all costs directly tied to producing or acquiring the product: raw materials, direct labor, manufacturing overhead, and packaging. It does not include marketing, administrative salaries, or office rent.

What does a negative profit margin mean?

A negative margin means your costs exceed your revenue — you're losing money on each sale. For an established business this signals a serious pricing or cost problem requiring immediate attention.

How does profit margin affect my taxes?

The IRS taxes your net profit (after all allowable deductions), not your revenue or gross profit. For pass-through entities, net profit flows to your personal return and is subject to income tax plus self-employment tax.

Can I use this for Amazon FBA or Shopify stores?

Yes. For Amazon FBA, include Amazon referral fees and FBA fulfillment fees in your COGS. For Shopify, include payment processing fees in operating expenses. Use Net Profit Mode for the most accurate view.

Quick Answer

Profit margin is the percentage of revenue that becomes profit. A 30% gross margin means $0.30 of every dollar in sales is gross profit. US businesses across retail, SaaS, and manufacturing use margin as the primary measure of pricing health.

Why Profit Margin Matters for US Businesses

The IRS, SBA, and lenders all care about your margin. Here's why you should too:

Pricing decisions: A widget that costs you $40 needs at least a 50% margin to cover overhead and still be profitable — that means a price of $80+, not just $50.
SBA loan applications: Banks typically require a minimum gross margin of 30–40% for product businesses before approving a small business loan.
Investor conversations: US venture capital firms and angel investors benchmark SaaS gross margins at 70–80%+ and retail at 40–60%.
Tax planning: Net profit margin directly affects your taxable income — understanding it early avoids surprises at year-end.
Competitive benchmarking: Comparing your margin to industry averages (see table below) tells you if your pricing is healthy or needs adjustment.

Formula Reference

Core Profit Formulas

Gross Profit

Gross Profit = Selling Price − Cost of Goods (COGS)

Gross Profit Margin %

Margin % = (Gross Profit ÷ Selling Price) × 100

Markup %

Markup % = (Gross Profit ÷ COGS) × 100

Selling Price from Target Margin

Selling Price = COGS ÷ (1 − Target Margin %/100)

Net Profit

Net Profit = Revenue − COGS − Operating Expenses − Other Expenses

Net Profit Margin %

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

Margin vs. Markup: What's the Difference?

These two terms are often confused — and mixing them up can cost you real money. Here's the exact difference:

Concept	Formula (denominator)	Example ($50 cost, $80 sell)	When to use
Profit Margin	Based on revenue	($30 ÷ $80) × 100 = 37.5%	Pricing & P&L
Markup	Based on cost	($30 ÷ $50) × 100 = 60%	Purchasing & wholesale
Gross Profit	Revenue − COGS	$80 − $50 = $30	Cash in hand
Net Profit	Revenue − All Expenses	$80 − $50 − $15 opex = $15	Tax & investor reporting

Key rule: A 50% markup is NOT the same as a 50% margin. A 50% markup on a $50 item gives you a $75 selling price and a 33.3% margin — not 50%.

Frequently Asked Questions

A gross margin of 40–60% is considered healthy for most US small businesses. For service businesses (consulting, marketing, design), 60–80% is common. Net profit margins of 10–20% are considered excellent — the average across all US industries is closer to 7–10%. Below 5% net margin is a red flag that expenses need cutting.

Profit margin is calculated as a percentage of your selling price (revenue). Markup is calculated as a percentage of your cost. A $10 profit on a $50 sale is a 20% margin but a 25% markup. Always specify which you mean when discussing pricing with suppliers or investors, as the numbers are very different.

Use the formula: Selling Price = Cost ÷ (1 − Desired Margin %/100). For example, if your cost is $60 and you want a 40% margin: $60 ÷ (1 − 0.40) = $60 ÷ 0.60 = $100. Use the "Find Selling Price" mode above to do this instantly.

No. Gross profit = Revenue minus direct costs (COGS) only. Net profit = Revenue minus ALL costs, including operating expenses like rent, salaries, utilities, marketing, taxes, and interest. Gross profit tells you if your product pricing is sound; net profit tells you if your whole business is profitable.

Yes. For Amazon FBA: your COGS should include the product cost plus Amazon referral fees, FBA fulfillment fees, and storage fees. For Shopify: include payment processing fees (typically 2.9% + $0.30) and Shopify subscription costs in your operating expenses. Use Net Profit Mode for the most accurate view.

A negative margin means you're losing money on each sale — your costs exceed your revenue. Early-stage startups sometimes accept negative margins intentionally (to acquire customers), but for an established business it signals a serious pricing or cost problem that needs immediate attention. Some high-growth US startups like Amazon operated at negative net margins for years while maintaining positive gross margins.

The IRS taxes your net profit (after all allowable deductions), not your revenue or gross profit. For pass-through entities (sole props, LLCs, S-corps), net profit flows to your personal return and is subject to federal income tax plus self-employment tax (15.3% on the first $168,600 in 2024). Understanding your net margin helps you estimate quarterly estimated tax payments accurately.

COGS (Cost of Goods Sold) includes all costs directly tied to producing or acquiring the product you sell: raw materials, direct labor, manufacturing overhead, shipping to you, and packaging. It does not include indirect costs like marketing, administrative salaries, or office rent — those belong in operating expenses. The IRS has specific rules on COGS capitalization under IRC §263A for inventory businesses.

Monthly at minimum for product businesses, and quarterly for service businesses. US businesses that review margins monthly catch pricing problems 3–4x faster than those who review annually. If you raise prices, change suppliers, add a new product line, or experience supply chain disruptions, recalculate immediately. Most US accountants recommend a monthly P&L review as best practice.

They're the same thing — profit margin and profit ratio both express profit as a percentage of revenue. The terms are used interchangeably in US business finance. "Profit ratio" is slightly more common in academic or financial analysis contexts, while "profit margin" is standard in everyday business usage and in tools like QuickBooks, Xero, and FreshBooks.
