What is Variance Analysis?

Variance analysis compares actual financial results with budgeted/forecasted numbers to identify differences. It helps you understand: Are we spending according to plan? Is revenue meeting targets? Which areas need immediate attention? What's driving over/under-performance?

Frequency: Monthly for most startups, weekly for fast-growing or cash-tight companies, quarterly for mature businesses. Consistent timing enables trend analysis.

Creating Your Budget

Annual budgeting process: Start 2-3 months before fiscal year-end. Bottom-up approach: Each department submits budget needs, then consolidate. Top-down approach: Leadership sets targets, departments allocate.

Budget components:

Budget assumptions: Document all assumptions (pricing, churn rate, hiring dates, inflation). Makes it easier to explain variances later.

Calculating Variances

Variance = Actual - Budget. Positive variance for revenue is good (exceeded target). Positive variance for expenses is bad (overspent).

Variance % = (Variance / Budget) × 100. This normalizes variances for comparison. ₹10L variance on ₹1Cr budget (10%) is less concerning than ₹10L variance on ₹20L budget (50%).

Example table:

Materiality threshold: Focus on variances >10% or >₹1L (whichever is lower). Don't waste time explaining ₹5,000 variances on ₹5L budget line items.

Analyzing Favorable vs Unfavorable Variances

Favorable variance: Actual is better than budget. Revenue higher than expected or expenses lower than budgeted. BUT investigate - could signal issues too.

Unfavorable variance: Actual is worse than budget. Revenue miss or cost overrun. Requires immediate investigation and corrective action.

Favorable variance scenarios:

Unfavorable variance scenarios:

Root Cause Analysis

For material variances, dig into the 'why' using these questions:

Example: Marketing expense 30% over budget. Root cause analysis: New paid ad channel tested (₹2L), agency fees increased (₹1L), event expenses brought forward from next month (₹1L). Conclusion: ₹2L test spend + ₹1L timing = acceptable. ₹1L agency increase = renegotiate contract.

Taking Corrective Action

Revenue miss actions:

Expense overrun actions:

Monthly variance review meeting: Finance presents variance report, department heads explain their variances, team discusses corrective actions, update rolling forecast, document decisions in meeting notes.
