I'm trying to get some revision in before an asssessment tonight, going straight from work so wont get a chance to check my books.

Forgotton how to calculate the difference in forecast and actual as a percentage.

As an example, lets say i forcasted to spend £150 but actually spend £207

How do i calculate the difference as a percentage?

Sorry if ive not explained this very well, not one of my strong points im afraid.

Thanks

(207 - 150) / 150 = 38 % (A)

Only thing to watch is the above was comparing costs so results in an Adverse Variance. If you had the same figures but comparing sales the variance would be favorable (sorry if this seems obvious).
