Why net income (NI) matters to a first-time founder
NI summarises overall accounting profitability after the business’s recognised costs. Founders use it to track performance, meet reporting requirements and calculate measures such as net profit margin. It does not show how much cash is available, so decisions about runway or debt repayment need cash-flow information too.
Examples of net income (NI)
A company records £600,000 of revenue, £420,000 of operating expenses, £20,000 of interest and £30,000 of tax. Its NI is £130,000. If customers have not yet paid £100,000 of recognised revenue, the company can report positive NI while holding much less cash.
Common misunderstanding
NI is not the same as operating income, EBITDA or cash flow. It includes interest, tax and other recognised items that operating measures may exclude. Accounting estimates and one-off gains can also affect it, so a positive bottom line does not automatically mean the underlying operations are strong.
When to use it
Use NI in financial statements, board reporting and profitability analysis, with the period and accounting basis clearly stated. Reconcile unusual movements and review cash flow alongside it. Because “NI” has other meanings, spell out net income on first use when the audience or context could be unclear.
