Read and manage cash-flow forecasts
Interpret a simple forecast, calculate net cash flow and balances, amend assumptions and consider ways to improve cash timing.

How is closing cash calculated from a simple forecast?
What you will learn
- Explain the purpose of a cash-flow forecast
- Calculate net flow and opening or closing balances
- Assess practical methods of improving cash flow
A forecast tracks expected cash timing
A cash-flow forecast estimates cash inflows and outflows over future periods. Net cash flow = total inflows−total outflows. Closing balance = opening balance + net cash flow; the closing balance for one period becomes the next period's opening balance.
A forecast can reveal when cash may fall below a safe level even when the business expects to be profitable. It is based on assumptions about receipts, payments and timing, so managers should update it when sales, costs or customer payments change.
A forecast supports action, not certainty
Possible ways to improve cash flow include collecting receivables sooner, negotiating supplier terms, reducing unnecessary inventory, delaying non-essential spending, arranging suitable short-term finance or increasing cash sales. Each option has costs or effects on relationships, service and long-term value.
When amending a forecast, change the relevant receipt or payment in the correct period and recalculate balances. Do not treat a loan as profit: it increases cash when received but creates a liability and future repayment.
Pause and explain
Opening cash is $4,000, receipts are $7,000 and payments are $9,500. What is closing cash?
Worked example
A business opens the month with $2,000, expects $8,500 cash inflows and $9,900 outflows. Calculate net cash flow and closing balance.
Show the worked solution
- Net cash flow = 8,500−9,900.
- Closing balance = opening balance + net cash flow.
- Check that the balance remains positive under the stated figures.
Answer Net cash flow is −$1,400. Closing cash is $2,000−$1,400=$600.

Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
Opening cash is $3,200. Receipts are $12,400 and payments are $13,100. Calculate net cash flow and closing balance.
Give me a hint
Subtract payments from receipts, then add the result to opening cash.
Compare my reasoning
- Net cash flow = 12,400−13,100.
- Add the net flow to 3,200.
- Label each result and preserve the negative sign.
Net cash flow is −$700. Closing balance is $3,200−$700=$2,500.
Look for these in your work
- Net flow is correct
- Closing balance uses the opening cash
- Negative flow is interpreted correctly
A customer receipt of $5,000 expected in June is delayed until July. Explain how to amend a cash forecast and what managers should watch.
Give me a hint
Move the receipt between periods; do not delete it or change profit automatically.
Compare my reasoning
- Reduce June receipts by $5,000.
- Increase July receipts by $5,000 if payment is still expected.
- Recalculate both closing balances and identify any shortfall or funding need.
June receipts fall by $5,000 and July receipts rise by $5,000 if collection remains expected. Recalculate both balances; June may require a cash buffer or suitable facility. The forecast should be updated if collection becomes uncertain.
Look for these in your work
- Receipt moves to the correct period
- Both periods are recalculated
- Shortfall risk is identified
A business considers offering a discount for early customer payment. Explain one cash-flow benefit and one cost or risk.
Give me a hint
Consider the timing of cash against the discount and customer response.
Compare my reasoning
- Earlier payment can reduce the period receivables remain outstanding.
- The discount reduces revenue per sale.
- Compare extra early receipts and avoided finance costs with discount cost.
The discount may accelerate cash receipts and reduce borrowing needs, but it lowers revenue per sale and customers might have paid on time anyway. Compare the discount cost with the value of earlier cash and any avoided finance charges before adopting it.
Look for these in your work
- Timing benefit is explained
- Revenue trade-off is recognised
- Incremental value is evaluated
Common mistakes
- Adding outflows to inflows
- Using the closing balance as next month's net cash flow
- Treating borrowing as profit rather than a cash receipt with a repayment obligation
What can you explain now?
How is closing cash calculated from a simple forecast?
Compare with the explanation
Opening balance plus net cash flow
Net cash flow is receipts less payments for the period.
