About the Cost Benefit Calculator
Cost-benefit analysis weighs project costs against benefits to determine if a project is worthwhile.
It is the classic analysis every infrastructure project starts with.
Formula
BCR = Total Benefits / Total Costs | Net Benefit = Benefits - Costs
- BCR
- — Benefit-Cost Ratio
- B
- — Total Benefits
- C
- — Total Costs
How to use this calculator
- 1
Enter total benefits
The total benefits of the project.
- 2
Enter total costs
The total costs of the project.
Example calculations
Road project analysis
A road project has $50M in benefits and $35M in costs.
BCR = $50M / $35M = 1.43. Net Benefit = $15M.
- Benefit-Cost Ratio:
- 1.43
- Net benefit:
- $15M
The project is worthwhile with a BCR of 1.43 and $15M net benefit.
Interpreting your results
BCR > 1.0: The project creates more benefit than cost.
BCR = 1.0: The project breaks even.
BCR < 1.0: The project does not pass the cost-benefit test.

The Cost Benefit Calculator is only as good as its inputs. Blackridge Research publishes syndicated market reports with vetted market sizes, growth rates, and competitive landscapes across 40+ industries — and builds custom studies when the shelf report doesn't exist.
Industry applications
Business
- Project evaluation: assess project viability.
- Investment decisions: compare BCR across projects.
- Budget allocation: prioritize projects by BCR.
Construction
- Infrastructure projects: evaluate public works projects.
- Development projects: demonstrate value to stakeholders.
Research
- Economic analysis: BCR is standard for public projects.
- Policy research: evaluate policy options.
Common mistakes to avoid
-
✗ Ignoring discounting
Future benefits and costs should be discounted to present value.
-
✗ Forgetting opportunity cost
Include the cost of capital as an opportunity cost.
Frequently asked questions
›What is a good benefit-cost ratio?
Above 1.0 is required. Above 1.5 is strong.
›What is the difference between BCR and ROI?
BCR compares benefits to costs. ROI compares returns to investment.
Glossary
- Benefit-Cost Ratio:
- Total benefits divided by total costs.
