Gearing

I think you mean the formulae for measuring the level of operational and financial gearing.

For financial gearing, you can look at the gearing ratio or you can look at the interest cover (or preferably both if the information is available).
You can find the formulae for these on page 74 of the Course Notes that are free on this website.

For operating gearing there are no standard measures. You can find suggested measures on page 77 of the Course Notes. The examiner will accept either of them.

For both financial and operating gearing, most of the marks will be for commenting on the level and the reasons and the impact – there are only a few marks for the actual numbers.

You are welcome
