Calculator questions

What is a healthy working capital ratio?

A current ratio of 1.5 to 2.0 is generally considered healthy. Below 1.0 may indicate the business cannot cover its short-term obligations. Above 2.0 may suggest assets are not being efficiently deployed.

How can I improve my working capital?

Reduce debtor days, extend creditor payment terms, reduce stock holdings, and consider a working capital facility such as invoice finance or a revolving credit facility.
