Liquidity and Working Capital Ratios for ACCA FR

Updated 11 October 2026 · Fact-checked

Liquidity ratios test whether a business can pay its short-term debts. The current ratio is current assets ÷ current liabilities. The quick ratio removes inventory. Receivables, payables and inventory days show how fast working capital moves. Cash operating cycle = inventory days + receivables days − payables days.

Understand Liquidity and Working Capital Ratios

Liquidity is about cash in the short term. A business can be profitable and still fail if it cannot pay suppliers, staff and lenders when they are due. Liquidity ratios look at the statement of financial position to judge this risk.

The current ratio compares current assets with current liabilities. A figure above 1 means current assets cover current liabilities. The quick ratio (acid test) removes inventory, because inventory can be slow to sell and may need discounts to turn into cash. The difference between the two ratios shows how much the business relies on inventory.

Working capital ratios show how fast cash moves through the business. Inventory days shows how long stock sits before sale. Receivables days shows how long customers take to pay. Payables days shows how long the business takes to pay suppliers. Together they give the cash operating cycle: the time between paying for inventory and collecting cash from customers.

A long cycle ties up cash and may need extra finance. A short cycle frees cash. But do not judge a number as good or bad alone. Compare it with prior years, with competitors, and with the type of business. A supermarket often has a current ratio below 1 and that is normal, because it sells for cash and buys on credit. A high payables days figure may mean good credit terms, or it may mean the business is struggling to pay.

In the exam, you must calculate and then interpret. Marks go for a clear reason linked to the scenario, not for the figure alone.

Key rules to remember

Current ratio: Current assets ÷ Current liabilities; Shown as a ratio, such as 1.5 : 1. Includes inventory.
Quick ratio: (Current assets − Inventory) ÷ Current liabilities; Also called the acid test ratio.
Inventory days: (Inventory ÷ Cost of sales) × 365; Use average inventory only if the question asks for it or gives opening figures.
Receivables days: (Trade receivables ÷ Credit revenue) × 365; Use total revenue if credit sales are not given, and state this.
Payables days: (Trade payables ÷ Credit purchases) × 365; If purchases are not given, use cost of sales and state this.
Cash operating cycle: Inventory days + Receivables days − Payables days; Measured in days. A shorter cycle usually means less cash is tied up.

How to solve Liquidity and Working Capital Ratios questions

Use this method for any liquidity or working capital question.

1Read the requirement. Note which ratios are asked for and who the user is, such as a lender or a supplier.
2Pick out the figures: current assets, inventory, current liabilities, receivables, payables, revenue and cost of sales.
3Write each formula, then calculate for every year given. Use 365 days unless told otherwise.
4Round consistently, usually to one decimal place for days and two for ratios.
5Calculate the cash operating cycle if days ratios are asked for.
6Compare the years or the entity with the benchmark. State the direction and size of each change.
7Explain likely causes using the scenario, such as slower collection, a new supplier deal or stock build-up.
8Finish with a conclusion for the user: is liquidity improving or worsening, and what should they do or ask next?

Quickest way: Table first, comment second

When to use it: Use this in Section C when several ratios are needed for two years and time is short.

Draw a small table with a column for each year and a row for each ratio.
Write the formula in one line beside each row so the marker can see your method.
Fill in the current and quick ratios first, as they use the same denominator.
Do the three days ratios, then add and subtract for the cycle.
Write one comment per ratio: change, likely reason, effect on cash.
Add one overall sentence on liquidity risk and a limitation, such as year-end figures not being typical.

Common mistakes in Liquidity and Working Capital Ratios

Using total revenue for receivables days when credit sales are given.
Students grab the first revenue figure in the statement.
Fix: Check the question for credit sales. If none is given, use revenue and say so.
Using revenue instead of cost of sales for inventory days or payables days.
Students apply the receivables formula to every days ratio.
Fix: Inventory is held at cost, so use cost of sales. Payables relate to purchases or cost of sales.
Adding payables days instead of subtracting it in the cash cycle.
All three figures are in days, so they look the same.
Fix: Payables give free credit, so they shorten the cycle. Subtract them.
Saying a current ratio below 1 is always bad.
Students learn a rule of thumb and apply it without thought.
Fix: Compare with the sector and trend. Retailers with fast sales often run below 1 safely.
Only describing the numbers: 'the ratio went up'.
Students think calculation earns most marks.
Fix: Give a reason and an effect, such as 'receivables days rose, so cash is tied up and more overdraft may be needed'.
Treating a higher payables days figure as always good.
Longer credit keeps cash in the business.
Fix: Say it may also signal cash shortage and risk of lost supplier goodwill or discounts.

Worked examples

Example 1

Year-end figures for Rolan Co: inventory ₹6,00,000; trade receivables ₹4,50,000; cash ₹50,000; current liabilities ₹8,00,000. Calculate the current ratio and quick ratio and comment.

Show the solution

Current assets = 6,00,000 + 4,50,000 + 50,000 = ₹11,00,000.
Current ratio = 11,00,000 ÷ 8,00,000 = 1.375, so 1.38 : 1.
Quick assets = 11,00,000 − 6,00,000 = ₹5,00,000.
Quick ratio = 5,00,000 ÷ 8,00,000 = 0.625, so 0.63 : 1.
Comment: the current ratio looks adequate, but over half of current assets is inventory. Without selling inventory, the company cannot meet all its current liabilities.

Answer: Current ratio 1.38 : 1; quick ratio 0.63 : 1. Liquidity depends heavily on inventory, so there is a risk if stock sells slowly.

Example 2

Tavi Co has revenue ₹36,50,000 (all on credit), cost of sales ₹26,00,000, and purchases ₹25,00,000. At the year end inventory is ₹3,50,000, receivables ₹4,00,000 and payables ₹2,50,000. Calculate the cash operating cycle using 365 days.

Show the solution

Inventory days = 3,50,000 ÷ 26,00,000 × 365 = 49.1 days.
Receivables days = 4,00,000 ÷ 36,50,000 × 365 = 40.0 days.
Payables days = 2,50,000 ÷ 25,00,000 × 365 = 36.5 days.
Cash operating cycle = 49.1 + 40.0 − 36.5 = 52.6 days.
Comment: cash is tied up for about 53 days between paying suppliers and collecting from customers. Faster collection or lower inventory would shorten this.

Answer: Cash operating cycle = 52.6 days (inventory 49.1, receivables 40.0, payables 36.5).

Exam tips

In Section C, the table of ratios usually earns a few marks, while the comments earn most of them. Leave time for the comments.
State your formula and any assumption, such as using revenue because credit sales are not given.
Link each comment to the user named in the question. A lender cares about solvency, a supplier about payment speed.
In objective test questions, check whether the question wants the ratio, the days, or the cycle, and read the answer options for units.
Mention a limitation where useful: year-end balances may not reflect average levels, especially for seasonal businesses.

Liquidity and Working Capital Ratios: frequently asked questions

What is the difference between the current ratio and the quick ratio?

The current ratio uses all current assets. The quick ratio removes inventory first. The quick ratio is a tougher test because inventory may be slow to turn into cash.

What is a good current ratio for ACCA FR?

There is no single correct figure. Compare with prior years and similar businesses. Some sectors, such as supermarkets, operate safely with a ratio below 1.

Should I use 365 days or 360 days?

Use 365 days unless the question says otherwise. Show your formula so the marker can follow your method.

Why is payables days subtracted in the cash operating cycle?

Payables days show how long the business uses suppliers' money without paying. This reduces the time the business must fund itself, so it shortens the cycle.
