Cash Flow Forecasting and Funding Needs in ACCA FM
Updated 11 October 2026 · Fact-checked
Cash flow forecasting lists expected cash receipts and payments period by period to show the closing cash balance. A negative balance is a funding deficit; a positive one is a surplus. For sales growth, work out the extra receivables and inventory less extra payables. That net increase is the extra funding needed.
Understand Cash Flow Forecasting and Funding Needs
A business can be profitable and still run out of cash. Profit includes credit sales, accruals and non-cash items. Cash only moves when customers pay and suppliers are paid. A cash flow forecast (or cash budget) shows this timing, so management can see problems before they happen.
The forecast works month by month. You list receipts (cash sales, receipts from receivables, asset sales, new finance) and payments (suppliers, wages, overheads, tax, dividends, capital spending, loan repayments). You then find the net cash flow for the month and add it to the opening balance to get the closing balance. Each month's closing balance becomes the next month's opening balance.
A negative closing balance is a funding deficit. A positive one is a surplus. Short-term deficits suit short-term finance such as an overdraft, a short-term loan or tighter credit control. Surpluses can be placed in short-term deposits or other low-risk, liquid investments. A deficit that lasts or keeps growing points to a permanent need and suits long-term finance.
Growth also absorbs cash. More sales need more inventory and more receivables. Payables rise too, and that offsets part of the cost. The net working capital investment is receivables plus inventory minus payables. If sales grow, you recalculate this balance at the new level. The increase is the extra funding needed, and it is a cash outflow in the year of growth.
Inflation has the same effect. Higher prices mean the same volumes tie up more cash. Examiners often ask you to calculate the funding need and then comment on suitable sources of finance.
Key rules to remember
- Closing cash balance
- Closing balance = Opening balance + Receipts − Payments
- The closing balance of one month is the opening balance of the next.
- Net working capital
- Net working capital = Inventory + Receivables − Payables (+ cash if included)
- Follow the question's definition. Most growth questions use inventory, receivables and payables only.
- Receivables balance
- Receivables = Annual credit sales × receivable days ÷ 365
- Use credit sales only. Use 360 or 52 weeks if the question says so.
- Inventory balance
- Inventory = Annual cost of sales × inventory days ÷ 365
- Use the base the question gives, usually cost of sales.
- Payables balance
- Payables = Annual credit purchases × payable days ÷ 365
- Use purchases if given. If not, use cost of sales as a stated approximation.
- Increase in working capital
- Funding needed = New net working capital − Old net working capital
- A rise is a cash outflow. A fall releases cash.
- Cash received from credit sales
- Cash received in month = Sales of earlier month × % paying after that credit period (less discounts taken)
- Apply the lag to the month of sale, not the month of receipt.
How to solve Cash Flow Forecasting and Funding Needs questions
Use this method for cash budgets and for growth-based funding questions. Layout is where most marks are earned or lost.
- 1Read the question and note the periods, the opening cash balance and the credit terms for receipts and payments.
- 2Draw a columnar layout with one column per period. Use rows for receipts, payments, net cash flow, opening balance and closing balance.
- 3Work out receipts first. Apply the credit lag to the month of sale. Remove any discounts and irrecoverable debts as instructed.
- 4Work out payments. Apply the payment lag to purchases and put wages, overheads, tax, dividends and capital items in the month they are actually paid.
- 5Leave out non-cash items such as depreciation and any profit figure. Only cash movements go in.
- 6Calculate net cash flow, then closing balance, and carry it forward. Note the largest deficit and when it occurs.
- 7For growth questions, compute receivables, inventory and payables at old and new levels. Find the net increase.
- 8Comment on funding. Match short-term deficits to short-term sources and permanent increases to long-term sources, and say what you would do with any surplus.
Quickest way: Rows-and-lags shortcut
When to use it: Use this in Section A or B when the question asks for one month's cash, one closing balance or a funding increase.
- Identify only the month asked for. Do not build the whole budget.
- Find which month's sales or purchases are paid in that month, using the stated lags.
- Cross out non-cash items such as depreciation straight away.
- For growth, find the percentage rise in sales. If days are unchanged and costs move with sales, each balance rises by that same percentage.
- Check the sign of the answer. A deficit is negative, and an increase in working capital is an outflow.
Common mistakes in Cash Flow Forecasting and Funding Needs
Including depreciation or other non-cash items in payments.
Students copy costs from an income statement without asking whether cash leaves the business.
Fix: Ask of every line: does cash move in this month? If not, leave it out.
Putting receipts in the month of sale rather than the month of cash receipt.
The sales budget is laid out by month of sale, so it is easy to carry it straight across.
Fix: Write the credit terms at the top and apply the lag line by line.
Forgetting that discounts reduce receipts.
Students focus on the lag and overlook the early-settlement percentage.
Fix: Receipt = sales × % taking discount × (1 − discount rate). Add the other group at full value.
Using total sales instead of credit sales to calculate receivables.
The question gives one sales figure and the student does not check for cash sales.
Fix: Strip out cash sales first, then multiply by days ÷ 365.
Treating the whole working capital balance as the funding need instead of the increase.
The balances look like answers by themselves.
Fix: Calculate the difference between new and old net working capital. Only the change needs new finance.
Recommending long-term finance for a temporary deficit, or an overdraft for a permanent need.
Students describe sources without linking them to the pattern of the deficit.
Fix: State whether the gap is temporary or permanent, then match the source and explain why.
Worked examples
Example 1
A company expects sales of ₹4,00,000 in January, ₹5,00,000 in February and ₹6,00,000 in March. All sales are on credit. 40% of customers pay in the month after sale and 60% pay two months after sale. November sales were ₹3,00,000 and December sales were ₹3,50,000. Calculate cash received from customers in each of January, February and March.
Show the solution
- January: 40% of December sales + 60% of November sales.
- 40% × ₹3,50,000 = ₹1,40,000. 60% × ₹3,00,000 = ₹1,80,000. Total = ₹3,20,000.
- February: 40% of January + 60% of December.
- 40% × ₹4,00,000 = ₹1,60,000. 60% × ₹3,50,000 = ₹2,10,000. Total = ₹3,70,000.
- March: 40% of February + 60% of January.
- 40% × ₹5,00,000 = ₹2,00,000. 60% × ₹4,00,000 = ₹2,40,000. Total = ₹4,40,000.
Answer: Cash received: January ₹3,20,000; February ₹3,70,000; March ₹4,40,000.
Example 2
A company has annual credit sales of ₹12,00,000 and cost of sales of ₹8,00,000, which is also its annual credit purchases. It holds inventory for 45 days, takes 60 days to collect from receivables and takes 30 days to pay suppliers. Sales are expected to rise by 25% next year, with cost of sales rising by the same percentage and all days unchanged. Use a 365-day year. Calculate the additional funding needed for working capital and say what type of finance suits it.
Show the solution
- Current receivables = ₹12,00,000 × 60 ÷ 365 = ₹1,97,260 (rounded).
- Current inventory = ₹8,00,000 × 45 ÷ 365 = ₹98,630 (rounded).
- Current payables = ₹8,00,000 × 30 ÷ 365 = ₹65,753 (rounded).
- Current net working capital = 1,97,260 + 98,630 − 65,753 = ₹2,30,137.
- New sales = ₹15,00,000 and new cost of sales = ₹10,00,000.
- New receivables = ₹15,00,000 × 60 ÷ 365 = ₹2,46,575. New inventory = ₹10,00,000 × 45 ÷ 365 = ₹1,23,288. New payables = ₹10,00,000 × 30 ÷ 365 = ₹82,192.
- New net working capital = 2,46,575 + 1,23,288 − 82,192 = ₹2,87,671.
- Increase = 2,87,671 − 2,30,137 = ₹57,534. Check: 25% × 2,30,137 = ₹57,534, which agrees.
- Comment: if the growth is permanent, the increase is a lasting need. Match it with long-term finance such as retained profits, a term loan or equity. A short overdraft can bridge the gap while that is arranged.
Answer: Additional working capital funding needed is about ₹57,534, a 25% increase. Because the higher sales level is permanent, long-term finance is the better match, with an overdraft as a short-term bridge.
Exam tips
- In Section C, use a clear columnar layout with a total row for receipts and payments. Marks are given for each correct line, so show your workings.
- In Section A and B, objective questions are all or nothing. Re-read which month the question asks about before you pick an answer.
- If days and margins are constant, each working capital item grows by the same percentage as sales. This lets you check your answer fast.
- Always finish a funding question with a short comment that links the size and duration of the deficit to a suitable source of finance.
- Show the assumptions you made, such as the use of 365 days or cost of sales as purchases, so you keep marks if the examiner takes a different view.

Cash Flow Forecasting and Funding Needs: frequently asked questions
How do I prepare a cash budget in ACCA FM?
Set out columns for each period. List receipts and payments by the month cash actually moves. Work out net cash flow, then add it to the opening balance to get the closing balance. Leave out depreciation and other non-cash items.
How do I calculate the increase in working capital from sales growth?
Calculate receivables, inventory and payables at the old and new sales levels using the same days. Net them to find old and new working capital. The difference is the extra funding needed.
What is the difference between a funding deficit and a surplus?
A deficit means forecast cash is negative, so you need finance to cover it. A surplus means cash is positive and can be invested short term or used for repayment, dividends or capital spending.
Which short-term finance suits a cash deficit?
An overdraft suits a temporary, fluctuating deficit. A short-term loan suits a known deficit for a fixed period. Faster collection from receivables or later payment to suppliers can also help. A lasting need should be financed with long-term sources.
