Benefit-Cost Ratio
The benefit-cost ratio compares the present value of monetized benefits with the present value of monetized costs under a defined appraisal perspective.
Cost-benefit tools compare discounted incremental benefits and costs, while decision cutoffs define the minimum criteria a project must satisfy.
Cost-Benefit Analysis is a structured appraisal process, not a single formula. It defines the decision, baseline, alternatives, perspective, time horizon, incremental effects, discounting, uncertainty, and non-monetized consequences before comparing options.
The Benefit-Cost Ratio summarizes discounted monetized benefits relative to discounted monetized costs. A ratio above one can support a project, but it does not establish affordability, strategic fit, acceptable risk, or superiority to a mutually exclusive alternative. Net present value and the ratio can rank projects differently because the ratio ignores scale.
A Cutoff Point identifies a minimum hurdle such as a required return, maximum payback period, or other screening threshold. Passing a cutoff is only one step in approval; evidence, capacity, financing, constraints, and governance still matter.
Compare each option with a credible business-as-usual baseline. Use incremental effects, a consistent perspective, matched real or nominal values and discount rates, and sensitivity analysis for material assumptions. Keep unmonetized effects visible instead of assigning unsupported prices merely to force them into a ratio.

Choose a subsection first. Deeper term pages live inside each subsection, which keeps large topic hubs readable.

Cost-benefit analysis compares the discounted incremental costs and benefits of alternatives against a defined baseline, including uncertainty and non-monetized effects.
In capital budgeting, the Cutoff Point represents the minimum acceptable rate of return on investments.
