Weights as percentages totaling 100. Other totals are automatically normalized to 100%.

Result
Highest weighted score
Offer C
- Offer C7.45 / 10
- Offer B6.70 / 10
- Offer A6.45 / 10
“Offer C” has the highest weighted score at 7.45 out of 10 points (74.5%), 0.75 points ahead of “Offer B”.
Calculation steps
- 1.Weights total: 100%. Each weight directly represents the criterion’s share in the decision.
- 2.Score per criterion = share of weighting × rating.
- 3.Utility score for “Offer C” = 0.3 × 5 + 0.25 × 9 + 0.2 × 8 + 0.15 × 8 + 0.1 × 9 = 7.45
- 4.This is how you calculate each option. The one with the highest utility score best meets your criteria.

How it works
Weighted decision analysis in six steps
No account needed, right in your browser.
Step 1
Enter offers
Enter the offers you want to compare—2 to 5, such as three server offers.
Step 2
Weight criteria
Add up to 12 criteria and give each a percentage weight. The calculator automatically adjusts weights that don't add up to 100.
Step 3
Choose a scale
Choose a scoring scale: 0–5 or 0–10 points.
Step 4
Compare offers
Score each offer against each criterion. More points always mean better, including for cost.
Step 5
Read result
See the overall scores, rankings and calculation steps. The calculator clearly indicates ties.
Step 6
Export or share
Copy the table as Markdown, download it as CSV, print it as a PDF or share the analysis by link.
Example
Scoring matrix example: three server offers
Five criteria, percentage weightings, and ratings from 0 to 10. The weighted score is weighting × rating; the utility score is the total for each offer.
| Criterion | Weighting | Offer A rating | Offer A weighted score | Offer B rating | Offer B weighted score | Offer C rating | Offer C weighted score |
|---|---|---|---|---|---|---|---|
| Purchase cost | 30% | 6 | 1.8 | 8 | 2.4 | 5 | 1.5 |
| Performance | 25% | 8 | 2 | 6 | 1.5 | 9 | 2.25 |
| Maintenance effort | 20% | 5 | 1 | 7 | 1.4 | 8 | 1.6 |
| Support | 15% | 7 | 1.05 | 6 | 0.9 | 8 | 1.2 |
| Scalability | 10% | 6 | 0.6 | 5 | 0.5 | 9 | 0.9 |
| Utility score | 100% | Rank 3 | 6.45 | Rank 2 | 6.70 | Rank 1 | 7.45 |
Formula
Utility score = Σ (weighting × rating)
The weightings add up to 100% (or 1). Rate each offer against each criterion on the same scale. The highest total wins.
Example result
“Offer C” has the highest weighted score at 7.45 out of 10 points (74.5%), 0.75 points ahead of “Offer B”.
- 1. Weights total: 100%. Each weight directly represents the criterion’s share in the decision.
- 2. Score per criterion = share of weighting × rating.
- 3. Utility score for “Offer C” = 0.3 × 5 + 0.25 × 9 + 0.2 × 8 + 0.15 × 8 + 0.1 × 9 = 7.45

Tips for a reliable weighted decision analysis
What matters when weighting, scoring and evaluating the results.
Weight first, then score
Set the weights before scoring the offers; otherwise, it's easy to adjust them to get the result you want. Check deal-breakers, such as a fixed budget, beforehand: leave any offer that fails one out of the matrix entirely.
Score costs correctly
All criteria use the same scale, and more points always mean better. For cost, the cheapest offer gets the most points and the most expensive gets the fewest.
Check close results
If two offers score closely, try changing the weights and see whether the ranking changes. The calculator updates the result with every change, but it doesn't perform a separate sensitivity analysis.
Limitations of the method
The weights and scores reflect your judgment. Weighted decision analysis makes them transparent, but not objective, and only evaluates the criteria you've considered. Briefly explain each weight.

FAQ
Frequently asked questions
Quick answers about weighted decision analysis, decision matrices, weighting and export.
A method for comparing multiple offers or solutions in a transparent way, also called a weighted decision matrix or scoring matrix. You define criteria, weight them by importance and score each option against each criterion. The weighted total is the overall score; the option with the highest score is the best fit.
For each criterion, multiply the weight by the score to get the weighted score. The sum of the weighted scores is the overall score. In the example on this page: “Offer C” has the highest weighted score at 7.45 out of 10 points (74.5%), 0.75 points ahead of “Offer B”.
Distribute 100% across the criteria, giving the most important one the largest share. Set the weights before scoring the offers so you don't skew the result. The calculator automatically normalizes other totals to 100%.
The calculator offers a 0–5 or 0–10 point scale. A 10-point scale gives you finer distinctions; a 5-point scale lets you score faster. All criteria use the same scale, and more points always mean better: for cost, the cheaper offer gets more points.
Use up to 12 criteria and 2 to 5 offers. Add or remove criteria and offers with one click and name them yourself.
Weighted decision analysis uses a weighted decision matrix: each criterion has a weight, each option gets points, and the weighted total determines the result. Other matrices work differently: the Pugh matrix compares options with a reference solution (better, equal or worse), while the Eisenhower matrix sorts tasks by urgency and importance. This calculator uses the weighted total.
Check whether the weights really reflect your priorities, or add a criterion that distinguishes the offers, such as support or contract length. The calculator clearly shows ties instead of arbitrarily ranking one option first.

Yes. Weighted decision analysis helps you justify a choice, such as hardware, software or hosting, in an IHK project report, a thesis or an offer comparison. Add the exported table and calculation steps to your document and briefly explain each weight.
The calculation runs in your browser. You don't need an account, and the calculator doesn't save your analysis on a server. Whenever you make a change, your values appear in the address bar so you can share the analysis by link. Anyone with the link can see your values.
