The Budget Variance Report Generator analyzes every line item — revenue, COGS, and each expense category — classifies each variance as favorable or unfavorable, explains the likely root cause, and recommends specific corrective actions. It applies a 5% materiality threshold and produces a 3-month forward forecast. Autonomous CFO intelligence, not a spreadsheet.

Frequently Asked Questions
What is a budget variance report?
A budget variance report compares planned vs. actual financial figures, classifies each difference as favorable or unfavorable, explains likely causes, and recommends corrective actions. It's a core CFO deliverable for monthly board reporting.
How do you calculate budget variance?
Budget variance = Actual − Budgeted. For revenue, positive = favorable (earned more than planned). For expenses, negative = favorable (spent less). Percentage variance = (variance ÷ budget) × 100. Variances above 5% or $10K are typically investigated.
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.
