What is Accounts Receivable Days?
Accounts Receivable Days is an accounting concept related to Accounts Receivable. It is the length of time it takes to clear all Accounts Receivable, or how long it takes to receive the money for goods it sells. This is useful for determining how efficient the company is at receiving whatever short-term payments it is owed.
Accounts Receivable Days Formula
The formula for Accounts Receivable Days is:
- (Accounts Receivable / Revenue) x Number of Days In Year
For the purpose of this calculation, it is usually assumed that there are 360 days in the year (4 quarters of 90 days). Accounts Receivable Days is often found on a financial statement projection model.
Interestingly, a report on the technology company Apple recently stated that Apple gets paid for its products before it actually has to pay for them. In practice, this means that Apple's Accounts Receivable (AR) Days is lower than its Accounts Payable (AP) Days. This ratio is important because it means Apple can effectively ramp up production to the very maximum level of consumer demand and will never be limited by cash flow (not that it would be anyway with $100bn in the bank). Most companies are not in this situation so in order to avoid having production constrained by free cash, it is desirable to minimise the difference between AR Days and AP days.
This concept can be slightly counterintuitive at times so an example is provided below to illustrate the principals.
An Example of Accounts Receivable Days
Imagine there is a company that only sells chairs and has $100 in the bank. Each chair costs $10 to produce and retails for $20. The company has a contract with its suppliers saying it will pay for materials 15 days after delivery but on average, its customers do not pay for products until 30 days (1 month free credit deal or similar) after purchase. So what does this imply?
Again for simplicity, we assume that the company receives the materials, converts them into a chair and sells the chair all within 1 day. So on day 1, the company takes delivery of materials for 10 chairs and sells all 10 to consumers and still has $100 in the bank. On day 16, it has to pay the supplier this $100 and will have $0 in the bank until day 31 where it receives $200 for the parts. This means that from day 16 until day 31, the company has no money and cannot produce so maximum profit per month is $100.
If the company were to reduce the time that consumers had to pay to less than the time in which it had to pay the supplier, it would get paid before it had to pay up meaning it could produce endlessly and never run out of cash. Now no company uses its entire cash reserves to order stock so the idea falls down a bit here, but the principal still applies.
In Apple's case, consumers pay for their products within 18 days but Apple does not have to pay suppliers for 83 days which implies they have money coming in roughly 4.5x faster
than going out (this would be if they sold products for what it cost to purchase which they do not, in reality their income flow would be 9x faster or greater than their expenditure).
