Net Profit Calculator
Calculate net profit and net profit margin — the true bottom line after every expense.
The Income Statement Waterfall
Net profit sits at the bottom of the income statement, which is why it's called the "bottom line." Understanding how it derives from revenue requires following a waterfall of deductions. Revenue minus COGS equals gross profit. Gross profit minus operating expenses equals operating income (EBIT). Operating income minus interest equals pre-tax income. Pre-tax income minus taxes equals net profit.
Each level has its own margin percentage, and each tells a different story. Gross margin reflects production efficiency. Operating margin shows whether overhead is manageable relative to revenue. Net margin is the complete picture — the ultimate test of a business's financial viability.
A company can have strong gross margins but poor net margins if it overspends on sales, marketing, R&D, or administrative overhead. This is characteristic of growth-stage technology companies: high gross margins (70%+) paired with significant negative net margins because they aggressively reinvest in growth. Investors evaluate these companies on gross margin trajectory and growth rate rather than current net profitability.
Net Profit vs Cash Flow: An Important Distinction
Net profit and cash flow are frequently confused but measure fundamentally different things. Net profit follows accrual accounting — revenue is recognized when earned, expenses when incurred, regardless of when cash actually changes hands. A business can show substantial net profit while simultaneously running out of cash.
Common reasons for profitable businesses to have cash flow problems: rapid revenue growth where inventory and receivables build faster than cash comes in; capital-intensive operations requiring upfront equipment purchases; long payment cycles from slow-paying customers; or high depreciation that distorts the relationship between accounting profit and actual cash generation.
Free cash flow — operating cash flow minus capital expenditures — is often a better indicator of a business's financial health than net profit for operational management purposes. Warren Buffett famously prefers businesses that convert earnings to free cash flow at high rates, arguing that accounting earnings not backed by cash are ultimately worthless.
What Net Profit Margin to Target
Net profit margin benchmarks vary enormously by industry. Software companies at scale achieve 15-30% net margins. Professional services firms: 10-20%. Manufacturing: 5-10%. Retail: 2-5%. Grocery: 1-3%. Restaurants: 3-9%. These ranges reflect the fundamental economics of each industry, not management quality alone.
A new or growing business with temporarily low or negative net margins is not necessarily in trouble — the relevant question is whether the path to sustainable positive margins is clear and well-funded. A mature business with declining net margins is a more serious concern: it suggests competitive pressure, rising costs, or structural problems that need addressing.
