tulokulku

Tulokulku is a Finnish term used in financial and economic contexts to denote the inflow of funds into an organization over a given period. The word combines tulon, the genitive form of tulo meaning income or revenue, with kulku meaning flow or movement. In practice, tulokulku refers to the aggregate of receipts from various sources that contribute to incoming cash, such as product and service revenues, licensing income, grants, donations, interest, and rental income.

In financial analysis and budgeting, tulokulku is often considered alongside cash outflows and overall cash flow. It is useful for forecasting and planning because it emphasizes the timing and sources of funds rather than profitability alone. The term can refer to both historical inflows and projected inflows, depending on the context, and is more commonly encountered in internal financial discussions, planning documents, and accounting discussions than in casual business reporting.

Examples of tulokulku include monthly subscription revenue for a digital service, one-time grants received by a nonprofit, licensing fees from intellectual property, and interest income from investments. By contrast, cash inflows are typically analyzed together with inflows from external financing or other offsetting items to assess liquidity and funding reliability.

Etymology and usage notes: tulokulku is a compound-native Finnish term. While it appears in Finnish financial writing, its usage may vary by organization, and it is often discussed alongside related concepts such as tulovirta (income stream) and kassavirta (cash flow).
