Short-term cash-flow forecast used to plan liquidity, borrowing needs, covenant headroom, and operating funding gaps.
A cash budget is a short-term forecast of cash inflows, cash outflows, and ending cash balance. It helps a company test whether it can meet payroll, supplier payments, debt service, taxes, capital spending, and minimum liquidity requirements.
Unlike an income statement budget, a cash budget focuses on when money actually enters and leaves the bank account. That timing difference is why a profitable company can still face a liquidity problem.
The core formula is:
A practical cash budget also compares ending cash with a minimum cash floor:
If the result is negative, the company needs a funding action, expense delay, working-capital improvement, or revised operating plan.
Cash budgets usually cover weekly, monthly, or quarterly periods. The shorter the liquidity runway, the more frequently the budget should be refreshed.
| Budget Line | Typical Inputs | Why It Matters |
|---|---|---|
| Beginning cash | Bank balances and treasury reports. | Sets the liquidity starting point. |
| Customer receipts | Collections forecast, sales terms, overdue receivables. | Converts revenue expectations into cash timing. |
| Operating payments | Payroll, rent, suppliers, utilities, taxes, and insurance. | Shows the cash cost of keeping operations running. |
| Capital spending | Approved capex, deposits, milestone payments. | Identifies investment cash needs. |
| Financing flows | Debt draws, repayments, interest, equity proceeds, dividends. | Shows whether external funding is needed or available. |
| Minimum cash floor | Treasury policy, lender covenants, or management buffer. | Defines the point where a funding gap becomes urgent. |
The cash budget should reconcile to the operating budget, capital expenditure plan, debt schedule, and working-capital forecast.
Suppose a business starts the month with $5,000 of cash. It expects $12,000 of receipts and $9,000 of payments.
If management requires a minimum cash balance of $6,000, the budget shows a $2,000 surplus:
The business can operate without immediate borrowing under this base case. A downside case with slower collections or higher supplier payments may produce a different result.
Operating Budget and cash budget are connected but not interchangeable.
| Question | Operating Budget | Cash Budget |
|---|---|---|
| What does it forecast? | Revenue, expenses, and operating profit. | Cash receipts, payments, and ending liquidity. |
| Accounting basis | Usually accrual accounting. | Cash timing. |
| Main risk shown | Margin, cost control, and operating performance. | Liquidity gaps, borrowing needs, and payment timing. |
| Key users | FP&A, operations, management, board. | Treasury, CFO, lenders, board, restructuring advisors. |
The operating budget may show profit while the cash budget shows a temporary cash shortfall because customers pay late, inventory builds, or capex is front-loaded.
Useful public sources can support company-context and benchmark inputs:
Public filings can support benchmark context, but the cash budget itself should tie to bank balances, customer collections, supplier schedules, payroll calendars, tax dates, debt terms, and the current forecast.
A company expects strong quarterly profit, but the cash budget shows ending cash below the lender’s minimum liquidity covenant for two weeks because a large customer pays after payroll and inventory purchases.
Answer: The cash budget is identifying a timing problem, not necessarily a profitability problem. Management may need to accelerate collections, draw on a revolver, delay discretionary payments, adjust inventory purchases, or negotiate timing before the covenant issue occurs.
A cash budget can mislead when:
Liquidity analysis should focus on the lowest cash point, not just the period-end balance.
Use cash budget as a liquidity control tool. The useful output is not only ending cash; it is the timing of cash gaps, the size of the funding need, and the action required before the company breaches a cash floor, misses a payment, or loses operating flexibility.
