Learning objective

By the end of this module, you should be able to:

  • Calculate key accounting ratios related to efficiency
  • Calculate and interpret the relationship between the elements of the financial statements regarding profitability, liquidity, efficient use of resources, and financial position.
  • Draw valid conclusions from the information contained within the financial statements and present these to the appropriate user of the financial statements.

Efficiency ratios
These are a group of ratios that measure how effectively a company manages its working capital (inventory, receivables and payables). This group of ratios includes:
  • Inventory turnover
  • Inventory days
  • Receivables collection period
  • Payables payment period
  • Cash operating cycle
Inventory turnover
This measures the number of times a company sells and replaces its inventory over a specific period (typically a year). It shows how quickly inventory is converted into sales.

Formula:

Inventory turnover=Average inventoryCost of sales​

Average inventory=2Opening inventory+Closing inventory​

Interpretation: A higher turnover ratio suggests inventory is sold quickly, which may indicate strong sales and effective inventory management. A lower ratio may signal weak sales, excess or obsolete inventories, or a deliberate early purchase ahead of price increases.

Inventory days
This measures the average number of days inventory is held before it is used or sold. This ratio is expressed in days, using 365 days in a year. Inventory days equals 365 divided by inventory turnover, so the two ratios always move in opposite directions: a higher turnover means fewer inventory days.

Formula:

Inventory days=Cost of salesAverage inventory​×365 days

Interpretation: The lower the number of days, the better. A higher number of inventory days might indicate holdings of obsolete or unsaleable inventory, but it might also reflect buying raw materials early in anticipation of a price increase or inventory still in the production process.

Receivables collection period
This measures the average number of days it takes customers to pay what they owe. Overall, it indicates how effectively short-term debts are being collected.

Formula:

Receivables collection period=Credit salesTrade receivables​×365 days

Interpretation: The lower the number of days, the better, because it indicates faster debt collection. A higher number of days (assuming the proportion of cash sales has not increased) indicates receivables are taking longer to pay. You’d typically investigate the terms of trade (credit policy) and whether there are long-outstanding debts that require provisions.

Payables payment period
This measures the average number of days it takes the company to pay its suppliers. It shows how much credit the company is taking. Overall, it reflects the company’s bargaining power with suppliers and its creditworthiness.

Formula:

Payables payment period=Credit purchasesTrade payables​×365 days

Interpretation: A longer period means the company is using supplier credit as free financing, but a period well beyond agreed terms may signal cash-flow difficulty, lost settlement discounts, or strained supplier relationships. A decrease in days may indicate the company is taking cash discounts, or it may indicate suppliers are reducing credit terms because of the company’s decreased creditworthiness.

Cash operating cycle
Also referred to as the cash conversion cycle (CCC) or cash cycle, this represents the number of days a company takes to turn cash spent on inventory into cash collected from sales. It helps you assess working capital management by tracking the time between paying suppliers and collecting from customers.

Formula:

Cash operating cycle=Inventory days+Receivables collection period−Payables payment period

Required: Calculate the following efficiency (activity) ratios for Sokoto Company Limited for the year ended 31 December 2024:

  1. Inventory turnover
  2. Inventory days
  3. Receivables collection period
  4. Payables payment period
  5. Cash operating cycle
  6. Compare each of your calculated ratios with the industry average provided above and comment on Sokoto Company Limited’s performance relative to the industry.

Suggested solution:

Try calculating the ratios and making the comparisons yourself before reviewing the suggested solution below.

  1. What is the inventory turnover ratio?
(spoiler)

Inventory turnover=Average inventoryCost of sales​

You can find inventory on the statement of financial position and cost of sales on the statement of profit or loss. Note: Since only the closing inventory is provided, the closing inventory is used instead of the average inventory.

Inventory turnover=$94,200$442,300​=4.7 times

Inventory turns 4.7 times, below the industry’s 5.2 times. This points to slower inventory movement than the industry benchmark, consistent with the longer inventory days calculated next.

  1. What is the inventory days?
(spoiler)

Inventory days=Cost of salesAverage inventory​×365 days

You can find inventory on the statement of financial position and cost of sales on the statement of profit or loss.

Inventory days=$442,300$94,200​×365 days=78 days

Inventory days of 78 days is slightly higher than the industry average of 70 days. This points to slower inventory movement than the industry benchmark, so it’s worth checking whether the company is holding excess inventories, carrying slow-moving items, or experiencing seasonal effects.

  1. What is the receivables collection period?
(spoiler)

Receivables collection period=Credit salesTrade receivables​×365 days

You can find trade receivables on the statement of financial position and sales on the statement of profit or loss. Note: Credit sales is not given explicitly, so total sales is used.

Receivables collection period=$935,200$119,808​×365 days=47 days

A receivables collection period of 47 days is better than the industry benchmark of 50 days. This suggests effective credit control and faster cash collection, which supports cash flow and reduces irrecoverable debt risk.

  1. What is the payables payment period?
(spoiler)

Payables payment period=Credit purchasesTrade payables​×365 days

You can find trade payables on the statement of financial position. Note: Credit purchases is not given explicitly. Cost of sales is given and is used here.

Payables payment period=$442,300$83,300​×365 days=69 days

A payables payment period of 69 days is higher than the industry average of 60 days. This suggests the company is taking longer credit from suppliers and using supplier financing more heavily.

  1. What is the cash operating cycle?
(spoiler)

Cash operating cycle=Inventory days+Receivables collection period−Payables payment period

Now combine the three working-capital timing measures.

Cash operating cycle=78 days+47 days−69 days=56 days

A cash cycle of 56 days is slightly below the 60-day industry benchmark. But inventory days plus receivables days (78 + 47 = 125) are longer than the industry’s (70 + 50 = 120), so Sokoto converts inventory and receivables into cash more slowly, not faster. The shorter cycle comes entirely from taking 9 extra days of supplier credit, which should be checked against agreed terms before calling working capital management efficient.

Summary table of the analysis

Ratio Sokoto Company Limited Industry average Variance
Inventory turnover 4.7 times 5.2 times -0.5 times
Inventory days 78 days 70 days +8 days
Receivables collection period 47 days 50 days -3 days
Payables payment period 69 days 60 days +9 days
Cash operating cycle 56 days 60 days -4 days

Overall assessment: Sokoto’s cash operating cycle (56 days) is slightly shorter than the industry’s (60 days), but only because it takes 9 more days of supplier credit. Its faster collection (47 against 50 days) is more than cancelled by slower-moving inventory (78 against 70 days), and the longer payables period should be checked against agreed supplier terms.

Note: This question only performed an industry-level comparison. In other questions, you may be given information for the same company for two (2) different years. The approach is the same: apply the formulas consistently, compare results, and interpret whether performance is improving or worsening, what factors may have contributed, and what actions could improve the results.

Efficiency ratios overview

  • Measure how well a company manages working capital: inventories, receivables, payables
  • Five core ratios: inventory turnover, inventory days, receivables collection period, payables payment period, cash operating cycle
  • Inventory turnover and inventory days are inversely related: Inventory days=365/Inventory turnover

Inventory ratios

  • Inventory turnover: Cost of sales/Average inventory — higher is better (faster sales/replenishment)
  • Inventory days: (Average inventory/Cost of sales)×365 — lower is better; high values may signal obsolete inventory or deliberate early purchasing
  • Use average inventory (Opening+Closing)/2 when both figures available; closing inventory only if opening not given

Receivables and payables periods

  • Receivables collection period: (Trade receivables/Credit sales)×365 — lower is better (faster collection); use total sales if credit sales not disclosed
  • Payables payment period: (Trade payables/Credit purchases)×365 — longer period = more supplier financing, but excessive delay may signal cash-flow strain or lost discounts; use cost of sales if credit purchases not disclosed

Cash operating cycle

  • Formula: Inventory days+Receivables collection period−Payables payment period
  • Measures time between paying suppliers and collecting from customers
  • A short cycle can be misleading if driven mainly by stretching payables rather than genuine efficiency in inventory/receivables management

Applying ratios: Sokoto Company illustration

  • Calculated vs industry average: inventory turnover 4.7 vs 5.2 times; inventory days 78 vs 70; receivables period 47 vs 50; payables period 69 vs 60; cash cycle 56 vs 60 days
  • Interpretation requires looking beyond the headline cash cycle number: Sokoto’s shorter cycle came only from stretching payables (+9 days), not from genuine efficiency, since inventory+receivables days (125) exceed industry’s (120)
  • General approach: compute each ratio, compare to benchmark (industry average or prior year), and explain drivers/implications rather than just stating better/worse

  4. Payables payment period
  5. Cash operating cycle
  6. Compare each of your calculated ratios with the industry average provided above and comment on Sokoto Company Limited’s performance relative to the industry.

Suggested solution:

Try calculating the ratios and making the comparisons yourself before reviewing the suggested solution below.

  1. What is the inventory turnover ratio?
(spoiler)

Inventory turnover=Average inventoryCost of sales​

You can find inventory on the statement of financial position and cost of sales on the statement of profit or loss. Note: Since only the closing inventory is provided, the closing inventory is used instead of the average inventory.

Inventory turnover=$94,200$442,300​=4.7 times

Inventory turns 4.7 times, below the industry’s 5.2 times. This points to slower inventory movement than the industry benchmark, consistent with the longer inventory days calculated next.

  1. What is the inventory days?
(spoiler)

Inventory days=Cost of salesAverage inventory​×365 days

You can find inventory on the statement of financial position and cost of sales on the statement of profit or loss.

Inventory days=$442,300$94,200​×365 days=78 days

Inventory days of 78 days is slightly higher than the industry average of 70 days. This points to slower inventory movement than the industry benchmark, so it’s worth checking whether the company is holding excess inventories, carrying slow-moving items, or experiencing seasonal effects.

  1. What is the receivables collection period?
(spoiler)

Receivables collection period=Credit salesTrade receivables​×365 days

You can find trade receivables on the statement of financial position and sales on the statement of profit or loss. Note: Credit sales is not given explicitly, so total sales is used.

Receivables collection period=$935,200$119,808​×365 days=47 days

A receivables collection period of 47 days is better than the industry benchmark of 50 days. This suggests effective credit control and faster cash collection, which supports cash flow and reduces irrecoverable debt risk.

  1. What is the payables payment period?
(spoiler)

Payables payment period=Credit purchasesTrade payables​×365 days

You can find trade payables on the statement of financial position. Note: Credit purchases is not given explicitly. Cost of sales is given and is used here.

Payables payment period=$442,300$83,300​×365 days=69 days

A payables payment period of 69 days is higher than the industry average of 60 days. This suggests the company is taking longer credit from suppliers and using supplier financing more heavily.

  1. What is the cash operating cycle?
(spoiler)

Cash operating cycle=Inventory days+Receivables collection period−Payables payment period

Now combine the three working-capital timing measures.

Cash operating cycle=78 days+47 days−69 days=56 days

A cash cycle of 56 days is slightly below the 60-day industry benchmark. But inventory days plus receivables days (78 + 47 = 125) are longer than the industry’s (70 + 50 = 120), so Sokoto converts inventory and receivables into cash more slowly, not faster. The shorter cycle comes entirely from taking 9 extra days of supplier credit, which should be checked against agreed terms before calling working capital management efficient.

Summary table of the analysis

Ratio Sokoto Company Limited Industry average Variance
Inventory turnover 4.7 times 5.2 times -0.5 times
Inventory days 78 days 70 days +8 days
Receivables collection period 47 days 50 days -3 days
Payables payment period 69 days 60 days +9 days
Cash operating cycle 56 days 60 days -4 days

Overall assessment: Sokoto’s cash operating cycle (56 days) is slightly shorter than the industry’s (60 days), but only because it takes 9 more days of supplier credit. Its faster collection (47 against 50 days) is more than cancelled by slower-moving inventory (78 against 70 days), and the longer payables period should be checked against agreed supplier terms.

Note: This question only performed an industry-level comparison. In other questions, you may be given information for the same company for two (2) different years.
