Purpose of This Step

The Budget Tracking Log (Step 2) shows what has been spent—but the Variance Analysis Table explains why that spending matters.

It helps your team:

Compare actual vs. planned costs
Identify over- or under-spending trends
Understand whether cost deviations are acceptable or need action
Link financial performance to project decisions and accountability

In short, this tool turns budget numbers into narrative insight and decision guidance.

Step-by-Step Instructions

1. Build the Table Structure

Add the following fields to your variance analysis table:

Column	Description
Category	Cost item or grouping (e.g., Dev Labor, Tools, Travel)
Planned Budget ($)	Original budgeted amount from Milestone 4
Actual Spend ($)	Cost incurred to date (from Budget Tracking Log)
Variance ($)	Formula: Actual – Planned
Variance (%)	Formula: (Variance ÷ Planned) × 100
Direction	Over Budget / Under Budget / On Target
Root Cause or Explanation	Brief reason for variance
Resolution or Action Taken	What the team did or will do about it

2. Set Variance Thresholds

Determine what level of variance deserves attention:

<5% → Acceptable (No action required)
5–15% → Monitor (Document and flag)
>15% → Escalate (Review for sponsor discussion or reallocation)

Tip: These thresholds may vary by cost type. For example, minor tool license shifts may be normal, while labor cost overruns should trigger action sooner.

3. Document Causes of Variance

For any line with a notable variance:

Identify what changed (scope shift, delay, price increase, usage error)
Avoid vague labels like “misc.” or “unexpected”
If savings occurred, explain whether it’s intentional or due to underutilization

Good Examples:

“Added 2 training seats due to stakeholder request”
“BA hours exceeded due to additional workflow review”
“Tool license under budget due to promo discount for Q2”

4. Document Resolutions or Decisions

For any variance >10%, state:

Whether it was approved in advance
Whether contingency absorbed the extra cost
Whether team behavior or planning assumptions need to change

Example Notes:

“Variance absorbed in contingency buffer. Added column to training tracker to flag scope creep.”
“Vendor invoiced at incorrect rate; resolved with credit applied next cycle.”

5. Example Table

Category	Planned ($)	Actual ($)	Variance ($)	%	Direction	Root Cause	Action Taken
BA Labor	5,100	5,865	+765	+15%	Over	Extended interviews with stakeholders	Flagged, reallocated from PM buffer
Hosting	1,200	900	-300	-25%	Under	Lower-than-expected usage tier	Reforecast next phase budget
PM Labor	4,950	4,950	0	0%	On Target	N/A	No action

6. Add a Summary Narrative (Optional)

At the top or bottom of your variance analysis sheet, include a short summary of budget health:

“As of Week 10, 3 out of 8 cost categories show notable variance. Two are over budget (BA Labor +15%, Training Tools +20%) and have been addressed through reallocation and risk communication. One under-spend (Hosting) is expected to remain consistent through project close.”

Why This Step Matters

Without analysis, your cost tracking is just data. This table:

Builds credibility with sponsors and finance stakeholders
Links your decisions to project health
Enables proactive course correction
Demonstrates financial leadership, not just accounting
