Variance analysis: explaining budget vs actual with flexed budgets, price and usage variances
For department managers, budget holders, management accountants, bookkeepers and finance business partners who have to explain why actual spending differs from budget. Complete 'Reading a budget vs actual report' and 'Budgeting: building and tracking a departmental budget' first. This course goes deeper: flexing the budget to the activity that actually happened, splitting a cost variance into price (rate) and usage (quantity) parts, classifying variances as timing or permanent and choosing which to explain, finding the cause with evidence, and writing commentary that a finance team can use. It uses the OpenStax managerial accounting text (flexible budgets and standard-cost variances) and the US GAO Green Book's expectation that management compares actual results with plans and analyses significant differences. Your company's budget policy, sign convention and reporting thresholds come first; this course isn't accounting advice.
