Business Tools
Use this vendor comparison calculator to rank vendor options with visible cost, fit, support, integration, risk, and weighting assumptions.
Live calculator
Score fit and support from 1 to 5. Lower integration effort and lower risk are better.
77.8 out of 100 weighted score.
Modeled over 12 months.
$3,400.00 spread between lowest and highest modeled cost.
Weights do not need to total 100; the calculator normalizes them.
The score is a vendor-screening aid, not procurement approval. Check security, contract terms, data ownership, implementation capacity, compliance, and exit cost before signing.
Use this for planning and comparison. Contracts, collections, payables, tax timing, payroll, refunds, one-time bills, seasonality, and accounting treatment can change the real business result.
Quick answer
Vendor Comparison Calculator calculates ranked vendor score from comparison months, feature fit weight, support weight, integration effort weight, risk weight and cost weight, and additional inputs. The visible formula is Score = weighted average of feature fit, support, low integration effort, low risk, and normalized low cost.
Formula
Score = weighted average of feature fit, support, low integration effort, low risk, and normalized low costLower integration effort, lower risk, and lower modeled cost improve the weighted score. Cost is normalized across the vendors entered.

Details
These notes make the assumptions explicit, especially where the same search query can mean slightly different things.
Use the same comparison period for every vendor so setup fees and subscriptions are comparable.
Feature fit and support are positive scores. Higher is better.
Higher integration effort or higher risk reduces the final score because those are cost-style criteria.
Benchmarks
The calculator is a decision aid, not a fixed rule. Use the output to compare scenarios and document your assumptions. Benchmark ranges are broad planning heuristics unless this page names a specific source for the range.
Often worth deeper diligence if contract, security, and implementation assumptions hold.
Usually needs a clearer discussion about fit, implementation, risk, and cost sensitivity.
When scores are close, review contract terms, data ownership, security, exit cost, and adoption risk.
Calculator accuracy

FAQ
Use the same time horizon, include setup and monthly costs, score each vendor against the same criteria, and separate cost from fit, support, integration effort, and risk.
No. A cheaper vendor can still be worse if feature fit, support, integration effort, risk, lock-in, or switching cost makes the total decision weaker.
Consider security, compliance, data ownership, uptime, contract lock-in, pricing changes, migration difficulty, roadmap risk, and exit cost.
Yes. It is built for software and service vendor comparisons where monthly cost, setup, feature fit, support, integration, and risk all matter.
No. Business tools are scenario planners. Contracts, taxes, payment timing, accounting treatment, refunds, and legal requirements can change decisions.
Save the assumptions, compare a conservative scenario, and review the result with actual books, contracts, or an advisor before making a high-stakes decision.
