A benefit-cost ratio (BCR) or benefit-cost analysis (BCA) or cost-benefit analysis (CBA) is calculated by dividing the present value of the benefits by the present value of the costs. If the ratio is greater than 1 then the benefits exceed the costs and the investment is worth considering. Benefit-cost analysis is often of most value when performed at the sector or national levels.
