How to Use This Calculator

Enter vendor names and scores for each evaluation criterion (price, features, support, reliability).
Set Weights for each criterion based on your organization's priorities.
Review Weighted Scores for each vendor.
Select the vendor with the highest weighted score — or use scores to inform structured negotiations.
Document your evaluation process — a scored matrix protects against procurement disputes and bias claims.

How the result changes with Vendor A quality score (0-10)

Vendor A quality score (0-10)	Vendor A weighted score	Vendor B weighted score
1	3.97	6.05
3.5	4.72	6.05
6.5	5.62	6.05
9	6.37	6.05

What each input means

Vendor A annual cost ($): Total annual cost for Vendor A's proposal.
Vendor A quality score (0-10): Rate Vendor A's product/service quality. 10 = excellent, 0 = poor.
Vendor A delivery score (0-10): Rate Vendor A's delivery reliability and speed.
Vendor A support score (0-10): Rate Vendor A's customer support and responsiveness.
Vendor B annual cost ($): Total annual cost for Vendor B's proposal.
Vendor B quality score (0-10): Rate Vendor B's product/service quality.
Vendor B delivery score (0-10): Rate Vendor B's delivery reliability and speed.
Vendor B support score (0-10): Rate Vendor B's customer support and responsiveness.
Weight: Cost (%): Importance weighting for cost. All weights are normalized to sum to 100%.
Weight: Quality (%): Importance weighting for quality.
Weight: Delivery (%): Importance weighting for delivery performance.
Weight: Support (%): Importance weighting for support quality.

What each result means

Vendor A weighted score: Vendor A's overall weighted score (0-10 scale).
Vendor B weighted score: Vendor B's overall weighted score (0-10 scale).
Score difference (A minus B): Positive = Vendor A leads, Negative = Vendor B leads.
Cost difference ($): Vendor A cost minus Vendor B cost. Positive = A is more expensive.
Vendor A value per $1K: Score points per $1,000 of cost for Vendor A. Higher = better value.
Vendor B value per $1K: Score points per $1,000 of cost for Vendor B. Higher = better value.
Recommended vendor (1=A, 2=B): Vendor with the highest weighted score.

How this is calculated

Worked example, using the default values

Identify Input Parameters
4 parameters
Vendor A annual cost ($) = 50000, Vendor A quality score (0-10) = 7, Vendor A delivery score (0-10) = 8, Vendor A support score (0-10) = 6 = 12 input(s) provided
Calculate Vendor A weighted score
Vendor A weighted score = vendorACostScore * wCost +
5.77 = 5.77
Calculate Vendor B weighted score
Vendor B weighted score = vendorBCostScore * wCost +
6.05 = 6.05
Calculate Score difference
Score difference = vendorAScore - vendorBScore
-0.28 = -0.28
Calculate Cost difference
Cost difference = vendorACost - vendorBCost
5000 = $5,000
