What is Budget Variance?
The gap between what you budgeted and what actually happened - and whether it helped or hurt.
Budget Variance: definition
Variance analysis is how a budget earns its keep after the period ends. Comparing actuals to budget line by line shows where the business beat or missed plan and, more importantly, why. A variance is favorable when it helps profit (higher revenue or lower cost than budget) and unfavorable when it hurts. The value is not the number itself but the explanation and action it prompts.
Budget variance
Variance = Actual − Budget (and Variance % = Variance ÷ Budget)
For revenue, actual above budget is favorable; for costs, actual below budget is favorable. Always interpret the sign in context.
How Fintra handles it
Fintra compares actuals to budget automatically on the same model, flags material variances by size or threshold, and - through flux analysis - attributes each variance to its drivers so you get an explanation, not just a number. Budget owners see their variances, closing the loop between planning and accountability.
- Automatic actual-vs-budget comparison across every line
- Material variances flagged by dollar or percentage threshold
- Flux analysis attributes variances to drivers and owners
Worked example
| Line | Budget | Actual | Variance | Type |
|---|---|---|---|---|
| Revenue | $500,000 | $540,000 | +$40,000 | Favorable |
| COGS | $200,000 | $225,000 | −$25,000 | Unfavorable |
| Marketing | $60,000 | $52,000 | +$8,000 | Favorable |
| Net effect | - | - | +$23,000 | Favorable |
Frequently asked questions
What is a favorable vs. unfavorable variance?
A favorable variance improves profit relative to budget - revenue higher than planned or costs lower than planned. An unfavorable variance worsens profit - revenue below plan or costs above plan. The label depends on the profit effect, not simply whether actual is above or below budget.
How do you calculate budget variance?
Subtract the budgeted amount from the actual amount. Express it as a percentage by dividing the variance by the budget. Then interpret the sign in context: for costs, actual below budget is favorable; for revenue, actual above budget is favorable.
What causes budget variances?
Volume differences, price or rate changes, timing, one-off items, or simply an inaccurate budget. Good variance analysis decomposes the gap into its causes - such as price versus volume - so the right action follows. Fintra flux analysis does this attribution.
What variance is worth investigating?
Set materiality thresholds - for example, any variance over a dollar amount or percentage of budget - so attention goes to what matters. Small, offsetting variances usually are not worth chasing. Fintra flags variances that cross the thresholds you set.
