  • Daily Operational Expense = (Operating Expenses – Non Cash Charges) / / 365

Note: Days may be your system of measure with this particular ratio.


Liquidity ratios allow the investor-analyst, in addition to creditors, to comprehend whether a business will have trouble fulfilling its obligations.
