Putting a Number on Doing Good: The Rise of Impact Measurement

Expressing a grant's value as a return on investment — dollars of benefit per dollar spent — would once have seemed crass in the world of charity. Today it is increasingly expected, part of a broader movement to measure social impact rigorously. The effort to quantify good is powerful, useful, and full of pitfalls.

From Good Intentions to Evidence

For much of philanthropy's history, good intentions and heartfelt stories were enough. A growing movement insisted on more: evidence that programs actually work and are worth their cost. This shift — toward outcomes, evaluation, and demonstrable impact — reflects a demand that limited charitable dollars go where they do the most measurable good.

Social Return on Investment

One influential idea is social return on investment, which attempts to translate a program's social benefits — better health, higher earnings, reduced costs to society — into monetary terms, so they can be compared against what was spent. It borrows the language of finance to make the value of social programs legible to funders and boards accustomed to thinking in dollars.

The Multiplier Argument

Reframing a program's value as a return has real power in advocacy: showing that a dollar of funding generated several dollars of value is a compelling case for renewal or expansion, and it lets otherwise incomparable programs be weighed on common ground. Funders wanting to maximize impact per dollar increasingly ask for exactly this kind of figure.

The Peril of False Precision

Yet quantifying good is fraught. Assigning a dollar value to a life changed, a habit broken, or a community strengthened involves assumptions that can be stretched to flatter a program. A precise ROI figure can lend false authority to soft estimates. Used honestly — with clear, documented definitions of value — the number illuminates; used loosely, it misleads.
