The graph uses your submitted values. Before submission, it shows sample project data.
Example Data Table
| Change ID | Category | Status | Cost Impact | Schedule Impact | Priority |
|---|---|---|---|---|---|
| CR-101 | Scope addition | Approved | 4500 | 8 days | High |
| CR-102 | Compliance update | Approved | 2200 | 4 days | Medium |
| CR-103 | Feature removal | Rejected | -1800 | -3 days | Low |
| CR-104 | Integration adjustment | Completed | 3100 | 6 days | High |
Formula Used
- Budget Variance = Revised Budget − Baseline Budget
- Budget Variance % = Budget Variance ÷ Baseline Budget × 100
- Schedule Variance = Revised Duration − Baseline Duration
- Schedule Variance % = Schedule Variance ÷ Baseline Duration × 100
- Net Scope Change = Added Scope Items − Removed Scope Items
- Scope Churn % = (Added + Removed Scope Items) ÷ Baseline Scope Items × 100
- Approval Ratio % = Approved Changes ÷ Total Change Requests × 100
- Completion Ratio % = Completed Approved Changes ÷ Approved Changes × 100
- Priority Pressure % = Urgent Changes ÷ Total Change Requests × 100
- Effort Load = Approved Changes × Average Effort Per Approved Change
- Change Impact Score blends budget, schedule, scope, urgency, and risk into a weighted 0–100 score.
- Risk Index combines impact score, urgency, and current risk rating into a single tracking measure.

Frequently Asked Questions
1. What does this calculator track?
It tracks budget change, schedule drift, scope churn, request approvals, delivery completion, urgency pressure, and a combined impact score for project governance.
2. Why is scope churn important?
Scope churn shows how much planned work moved in or out. High churn usually signals unstable requirements, rework risk, and difficulty protecting milestones.
3. What does a high change impact score mean?
A high score means project changes are creating stronger pressure on cost, timeline, scope stability, urgency, or risk. It helps flag when governance needs escalation.
4. Can negative budget variance be good?
Yes. A negative value means revised cost is below the baseline. That can indicate savings, descoped work, or better delivery efficiency.
5. Why can the total request count adjust automatically?
If approvals, rejections, urgent items, or completed items exceed the entered total, the calculator raises the total so ratios remain logically consistent.
6. Is this useful for agile and waterfall teams?
Yes. Agile teams can track backlog-driven scope movement, while waterfall teams can measure formal request impacts against approved baselines.
7. What should I do with the risk index?
Use it to support steering meetings, sponsor updates, and rebaseline discussions. It summarizes change pressure into one practical monitoring number.
8. Does the export include calculated results?
Yes. The CSV and PDF tools export the calculated summary values shown in the results section, helping you share updates quickly.
