Accounts Receivable Turnover= annual net revenue
Accounts receivable turnover represents the average number of times per year that trade receivables "turn over" or are converted to cash. Higher, more rapid turnover is favorable, since sales on credit are being converted to cash more quickly. Lower, less rapid turnover is unfavorable since default becomes more likely as receivables remain uncollected, and since conversion to cash is necessary to service obligations or to earn interest.
A problem with this ratio is the fact that it compares accounts receivable at a single point in time to an entire year of sales. If the accounts receivable balance is unusually high or low on the date of the financial statements due to seasonal variations or other factors, then this measurement may not provide an accurate picture. Substituting average receivable balances over the year in the denominator, may help correct this.
