# Understanding Activity Ratios

Understanding activity ratios is a very important tool for evaluating a company’s performance. Whether interpreting the financial ratios for your company or evaluating another company, it is basic to understand what the activity ratios indicate about a company’s performance. Activity ratios are frequently referred to as efficiency ratios because they measure how efficiently the company is managing their assets. Activity ratios can be broken down into two categories; turnover ratios and days on hand ratios.

Accounts Receivable Ratios

Accounts Receivable Turnover = Net Sales ÷ Net Accounts Receivable

The accounts receivable turnover ratio measures how many times, on average, accounts receivable are collected in cash, or “turns”, during the fiscal year.

Accounts Receivable Days on Hand = Net Accounts Receivable ÷ Net Sales X 365

Accounts receivable days on hand (ARDOH) is the average number of days required to transform receivables into cash. The accounts receivable days on hand measures the ability of a firm to collect from its customers. This number should be compared to the company’s stated credit terms. By comparing this number to past years, we can determine if there is an identifiable trend in accounts receivable. An increase in ARDOH could average that the company has increased credit terms in an attempt to increase sales or poor accounts receivable management. As a rule of thumb, the upper permissible limit for a firm’s average collection period should be 50% more than the stated terms. For example, if a company has stated terms of 30 days, the upper limit would be 45 days. Anything longer than 45 days would be cause for concern. If A/R days on hand is lower than the stated terms a company is doing an excellent job of collecting receivables. If A/R days on hand is above the stated credit terms management may need to tighten credit to lower receivables.

The A/R days on hand ratio is extremely important because it allows us to put a company’s accounts receivable balance, from the balance sheet, into perspective. If a company has \$1,000,000 in accounts receivable, that my look good just glancing at the balance sheet, however if we discover the A/R days on hand is well above the company’s stated credit terms, we should question how much of that \$1,000,000 is really collectible. In this case you would want to see an accounts receivable aging to determine how much is likely uncollectable.

Inventory Ratios

Inventory Turnover = Cost of Goods Sold ÷ Inventory

Inventory turnover measures how many times, on average, inventory is sold during the year.

Inventory Days on Hand = Inventory ÷ Cost of Goods Sold X 365

Inventory days on hand measures how many days of inventory a firm has on hand at any given time. The inventory days on hand should be compared to past years to determine the trends affecting inventory and the industry average. Too high of a number could indicate poor inventory management or out of use, unsalable, or stale inventor. For example, if a company’s inventory days on hand is 70 days in year 1 and it experiences a jump to 90 days in year 2, the company needs to understand why there was a huge jump in inventory days on hand. There may be many likely reasons for the slowdown, such as increased inventory in anticipation of a future shortage, out of use or stale inventory, or poor inventory management. However, if 90 days is the industry average, the jump may not be a major cause for concern. It would be necessary to question management to help understand why the inventory days on hand changed.

Accounts Payable Ratios

Accounts Payable Turnover = Cost of Goods Sold ÷ Accounts Payable

Accounts payable turnover ratios measure how many times, on average, accounts receivable are collected in cash, inventory is sold, and payables are paid during the year.

Accounts Payable Days on Hand = Accounts Payable ÷ Cost of Goods Sold X 365

Accounts payable days on hand is the average number of days it takes to pay payables in cash. This ratio gives insight into a company’s pattern of payments. This should be measured against the terms offered to a company by its suppliers. If the number is higher than the terms offered by suppliers, it may be a cause for concern because suppliers may require cash on delivery. However, a low accounts payable days on hand increases the operating cycle and can cause a need for outside financing.

Operating Cycle

Another useful tool in evaluating a company’s efficiency is calculating the operation cycle.

Operating Cycle = A/R Days on Hand + Inventory Days on Hand – A/P Days on Hand

It is important to understand the relationship these three ratios have in affecting the cash flow of a company. The operating cycle is determined by adding the A/R days on hand and inventory days on hand and subtracting the A/P days on hand. Simply put, the operating cycle is the amount of time it takes a company to buy and manufacture goods, pay for the goods, sell the goods, and receive cash for items sold. If a company experiences an increase to A/R days on hand or inventory days on hand, while A/P days on hand stays continued, they will increase their need for outside financing.

Understanding activity ratios is basic to evaluating a company’s performance and efficiency. It is important to understanding how a change in A/R days on hand, inventory days on hand, and A/P days can effect a company’s operating cycle. Business owners, managers, and investors can all assistance from a substantial understanding of activity ratios.
