What is a budget variance report?

A budget variance report compares planned (budgeted) financial figures against actual results, highlighting where performance differed and by how much. It classifies each variance as favorable (better than budget) or unfavorable (worse than budget) and explains likely causes.

How do you calculate budget variance?

Budget variance = Actual Amount − Budgeted Amount. For revenue, a positive number is favorable (you earned more than planned). For expenses, a negative number is favorable (you spent less than planned). Percentage variance = (Variance / Budgeted Amount) × 100.

What variances are material enough to investigate?

Most CFOs use a 5–10% threshold: variances exceeding 5% of budget or $10,000 (whichever is smaller) are investigated. One-time items, seasonal patterns, and known timing differences are noted separately to avoid false alarms.

What causes unfavorable budget variances?

Common causes include: inaccurate initial forecasts, unexpected cost increases (materials, labor, SaaS), revenue shortfalls from missed deals or churn, timing differences (cost recognized earlier than planned), and scope creep on projects.
