What it means
The projection is deliberately built on payment dates rather than accounting dates. An invoice dated March but paid in April belongs in April, because the point of the exercise is to know what the bank balance will look like, not what the profit and loss account will say.
Most finance teams build the projection in weekly buckets for the next three months and monthly buckets beyond that. The near term weeks are largely known facts, since the supplier ledger already contains the invoices and their due dates, while the later months rely on assumptions about volumes and cost inflation.
It matters because payments are far less flexible than receipts. Payroll, rent, loan instalments and tax bills arrive on fixed dates whether or not customers have paid, so a business that misjudges its outflows can be perfectly profitable and still miss a payment run.
The best projections separate committed outflows from discretionary ones. Wages and debt service are non negotiable, whereas marketing spend, recruitment and equipment purchases can be delayed, and knowing which is which gives management a set of levers to pull when the forecast tightens.
A common refinement is to overlay a stress case in which a large customer pays a month late or a key input price rises 10%. Running that alternative alongside the base case tells the board how much headroom actually exists before a facility needs to be drawn.
In practice
Real-world examples.
Example
A construction subcontractor maps out subcontractor payments, plant hire and materials for the next thirteen weeks and spots a week where three payment runs and a tax bill collide. The finance manager moves one payment run forward by four days and avoids an unplanned overdraft.
Example
A software company projecting outflows for the coming year separates its annual cloud hosting renewal of $240,000, due in a single March payment, from its monthly costs. Seeing that spike months ahead, the team negotiates quarterly billing instead.
Example
A family run hotel builds an outflow projection before signing a refurbishment contract. The projection shows the third stage payment landing in the quietest trading month, so the contract is redrafted to move that milestone into the summer.
Think of it
“Cash outflow projection is forecasting what you'll have to pay-predicting your future cash disbursements.
Formula
Calculation
Projected cash outflows = supplier payments + payroll and related costs + premises and overheads + tax payments + loan interest and repayments + capital expenditure
A specialist coffee roaster projects the following for October: supplier payments of $420,000, payroll including employer contributions of $310,000, rent and utilities of $65,000, a quarterly tax payment of $80,000, loan interest and capital repayment of $45,000, and a $30,000 deposit on a new roasting machine.
Total projected outflows = $420,000 + $310,000 + $65,000 + $80,000 + $45,000 + $30,000 = $950,000.
With opening cash of $600,000 and projected receipts of $880,000, the closing balance is $600,000 + $880,000 - $950,000 = $530,000. Under a stress case where a $150,000 customer payment slips into November, receipts fall to $730,000 and closing cash drops to $380,000, still positive but close enough to the $350,000 covenant floor to warrant deferring the machine deposit.Case study
Seen in the real world.
The following is an illustrative, clearly fictional story. Harbourgate Logistics, an invented regional haulage firm, had always forecast revenue carefully but treated costs as a single monthly average of $780,000. The average was accurate over a year and badly wrong in any given week, because fuel was paid weekly, wages fortnightly and vehicle finance on the 20th.
After a near miss in which the fictional company came within $9,000 of bouncing a finance instalment, the controller rebuilt the forecast as a dated outflow projection at daily level for the next six weeks. It immediately showed that the third week of every month carried $340,000 of payments against $190,000 of expected receipts.
Harbourgate's imagined solution was unglamorous and effective: it moved the vehicle finance collection date to the 28th and shifted two supplier payment runs by a week. No cost changed, but the worst week of the month stopped being a crisis.
Watch out
Common mistakes.
- Building the projection from the profit and loss account, which records costs when they are incurred rather than when they are paid and therefore misses the timing that matters.
- Forgetting the outflows that never appear as an expense, such as loan capital repayments, dividend payments, tax paid on last year's profit and deposits on equipment.
- Projecting a single optimistic case and presenting it to the board as fact, with no stress case showing what happens if a large receipt slips.
Questions
People also ask.
How far ahead should a cash outflow projection run?
Thirteen weeks in detail is the common standard for day to day management, extended to twelve or eighteen months at monthly level for planning and covenant testing.
Should sales tax be included?
Yes, treat it as a real outflow on its due date, because the cash sits in your account until it is paid over and is easy to spend by accident.
What is the biggest source of error in practice?
Payroll related costs, since employer contributions, pension payments and bonus timing are often left out of a first draft and can add 20% or more to the wage line.
