There is no point reaching for a calculator that cannot show its working. This one starts from beginning current assets, beginning current liabilities, current assets, current liabilities, ending current assets, ending current liabilities and revenues and reports working capital turnover ratio, beginning working capital and average working capital, so you can see how each answer follows from the numbers you entered.
What Is the Working Capital Calculator?
The working capital calculator takes beginning current assets, beginning current liabilities, current assets, current liabilities, ending current assets, ending current liabilities and revenues and turns them into working capital turnover ratio, beginning working capital and average working capital.
It is the kind of calculation you would otherwise do on the back of an envelope: mechanical, repeatable and easy to get subtly wrong without noticing.
How the Working Capital Figure Is Built
Each result is calculated from the ones before it, so the working is fully visible. That matters when the answer is going to be quoted to somebody else and you need to be able to explain where it came from.
The figures are exactly as good as the assumptions underneath them. Check the rates, the periods and the tax treatment before you rely on the result.
Reading the Result Sensibly
A small change in an input can move the result by much more than you would expect, particularly where the calculation divides by one of the figures you supplied. That is worth understanding before you rely on a figure.
For anything that will be committed to, write the inputs down beside the result. A number you can reproduce is worth far more than one you cannot explain.
A Worked Example
Working through an example, with beginning current assets set to 10, beginning current liabilities set to 5, current assets set to 2, the calculator returns working capital of -98, and working capital ratio of 0.02, and ending working capital of 5. Substitute your own figures and the same steps produce the same kind of answer.
Frequently Asked Questions
What do I need to work out working capital turnover ratio?
Enter beginning current assets, beginning current liabilities, current assets, current liabilities, ending current assets, ending current liabilities and revenues. The calculator then works through the relationship and reports working capital turnover ratio, beginning working capital and average working capital.
What does the working capital actually calculate?
It takes beginning current assets, beginning current liabilities, current assets, current liabilities, ending current assets, ending current liabilities and revenues and converts them into working capital turnover ratio, beginning working capital and average working capital using the standard relationship for this problem. Each step is applied in turn, so every output is traceable back to the numbers you typed in.
How should I enter beginning current assets?
Use the value you actually have, in the unit shown next to the field. Enter every value in the same unit system. The calculator assumes the figures you supply are consistent, so it cannot correct a mistake that happens before the calculation starts.
Is the answer exact?
It is as exact as the formula and the inputs allow. The method itself is the standard one for this problem, so the only sources of error are the figures you enter and the precision you ask for.
Can I use this for a quick estimate as well as a precise answer?
Yes. The calculator is built for quick checks, so round your inputs to a sensible number of significant figures and the result will be just as useful. If you need more precision, keep the same method and add digits to the inputs rather than adjusting the method itself.
