There are three primary causes of budget variance: errors, changing business conditions and unmet expectations. Errors by the budget creators can occur when the budget is being compiled. There are a number of reasons for this, including faulty math, using the wrong assumptions and relying on stale or bad data. Changing business conditions, including changes in the overall economy, can cause budget variances.
In its simplest form a budget is a plan or forecast in the form of a list, showing spending items and/or incoming revenue items, with a figure for each item. As time passes, actual spending or revenue may be entered into the list to compare with the originally budgeted figure.ere, a positive variance means that spending is over budget and a negative variance means that spending is under budget. However, note that this convention is not universally observed: some people prefer to show overspending as a negative figure by calculating variance as the planned figure less the actual figure.
