Benefit-Cost Ratio (BCR)
The Benefit-Cost Ratio, or BCR, is a simple way to compare what you expect to *gain* from a project (the benefits) against what you expect to *spend* on it (the costs). Both numbers are usually measured in money. You calculate it by dividing the total benefits by the total costs.
Reading the result is easy once you know the tipping point is the number 1. If your BCR is greater than 1, it means the benefits are bigger than the costs — the project is expected to pay off. If it's exactly 1, benefits and costs are equal, so you break even. If it's less than 1, you'd be spending more than you get back, which is a warning sign.
A project manager uses BCR early on, during selection, when the organization is deciding which projects are worth doing. When you have several possible projects competing for limited money, a higher BCR generally means better value for each dollar spent — so it helps leaders pick the strongest option.
Think of it like shopping for a coupon deal: if a $10 coupon saves you $30 on groceries, you're getting three times your money back. A BCR above 1 is that same 'I got more than I paid for' feeling, measured as a ratio.
Imagine a project is expected to deliver $500,000 in benefits and will cost $250,000 to complete. You divide the benefits by the costs: $500,000 ÷ $250,000 = 2.0. A BCR of 2.0 means that for every $1 you spend, you expect to get $2 back in benefits. Because 2.0 is greater than 1, this project looks financially worthwhile.
