Project RAG Status Calculator
Use this calculator to estimate your project health as Red, Amber, or Green based on schedule, budget, risk, delivery, and stakeholder confidence.
What is a RAG calculator?
A RAG calculator is a quick scoring tool used in project management to convert raw project indicators into a simple status:
- Green: healthy and on track
- Amber: caution, requires attention
- Red: serious issues, immediate intervention needed
Leaders use RAG status in steering committees, weekly standups, PMO reporting, and portfolio dashboards because it gives a fast signal without forcing everyone to read a long status report first.
How this calculator scores your project
This page uses a weighted model to produce a health score out of 100. Each input contributes to your final result.
1) Delivery progress (30%)
Tasks on track is the single biggest weight. If planned work is slipping, problems usually appear in budget and risk soon after.
2) Budget variance (20%)
Being over budget reduces your score. Under budget does not get an extra bonus here; it simply avoids penalty.
3) Schedule variance (20%)
Behind schedule reduces project health. Teams ahead of schedule are treated as fully healthy for this component.
4) Open high-priority risks (15%)
Each unresolved high risk lowers confidence in delivery and increases the chance of a red outcome later.
5) Stakeholder confidence (15%)
This captures the “human signal” that hard metrics can miss. If sponsors lose confidence, escalation usually follows.
How to read the result
- 80 to 100 = Green: Continue execution, monitor trends, and keep communication steady.
- 60 to 79.9 = Amber: Add mitigation actions, increase reporting frequency, and protect near-term milestones.
- Below 60 = Red: Escalate quickly, cut scope or re-baseline, and assign clear owners for recovery actions.
Example use cases
Software rollout
If a rollout is 88% on-track, 3% over budget, 5% behind schedule, with 2 high risks and confidence at 8/10, the project may land in Amber or low Green depending on trend direction.
Infrastructure program
A project with many external dependencies might show only 62% tasks on track, 11% over budget, and 6 open high risks. Even with decent stakeholder confidence, that profile tends to return Red, signaling urgent recovery planning.
How to move from red or amber to green
- Break large milestones into shorter checkpoints with clear owners.
- Limit work in progress so teams finish critical tasks before starting new ones.
- Escalate blocked decisions early; waiting usually worsens schedule variance.
- Review high risks weekly and confirm mitigation actions are actually funded.
- Share concise progress notes with stakeholders to rebuild confidence through transparency.
Common mistakes when using RAG status
- Over-simplifying: RAG is a signal, not the full story. Include context and trend direction.
- Late updates: Monthly-only reporting hides fast-moving issues.
- Optimism bias: Teams may hold Amber when evidence already points to Red.
- No action plan: Status color without owner-assigned actions creates false control.
Final thoughts
A practical RAG calculator helps teams make better decisions faster. It standardizes status discussions, exposes risk early, and supports clear escalation before small variances become expensive failures. Use the calculator above as a starting framework, then tune the weighting and thresholds to match your governance model.
