An annual budget is the company’s twelve-month financial plan—forecasting revenue, operating expenses, headcount, and cash burn tied to strategic goals.

How it works

Finance builds bottom-up models: sales quotas, marketing programs, cloud costs, and payroll by department. The board approves a budget at fiscal year start or after a financing. Monthly or quarterly actuals compare to budget (variance analysis); large misses trigger conversation about cuts, reforecast, or fundraising.

Venture-backed budgets often include scenario tabs—base, upside, downside—to stress-test runway if growth slows. Budgets link to hiring plans and covenant reporting for venture debt.

Why it matters

• Founders: A budget is permission structure—helps you defer hires until metrics justify them.
• Investors: Persistent beat-and-raise earns trust; silent overspend without reforecast erodes it.
• Operators: Department leads should own line items they control, not a finance-only artifact.

Common mistake

Building a budget that only works if every growth assumption hits perfectly, with no contingency line. Boards want honest downside cases.
