Impact Rating

Benevolent Missions International

Top Health Nonprofit

Impact: $80 cures one person of blindness.

Cataract Surgery Program meets the benchmark for high cost-effectiveness. The nonprofit averts a disability-adjusted life year for less than the country's G.D.P. per capita.

Note: The impact of this program may not be representative of the entire operation of Benevolent Missions International.

Impact: The cost to achieve an outcome.

Cost-effectiveness: A judgment as to whether the cost was "worth" the outcome.


Outcome Metric

A person cured of blindness

To calculate impact, we estimate how many outcomes the nonprofit caused.

Data Source

Output data collected during the program. Benevolent Missions International publicly reports data on how many surgeries it performs, which we use to calculate how many people it cures of blindness.

Time Period of Data

Jan. 1, 2017, to Dec. 31, 2017

Ratings are based on data the nonprofit itself collects on its work. We use the most recent year with sufficient data. Typically, this data allows us to calculate direct changes in participants' lives, such as increased income.

Method for Attributing Outcomes

We estimate the number of people the nonprofit cured of blindness by comparing the number of people whose blindness was actually cured to the number of people whose blindness would have been cured even in the absence of the nonprofit (the "counterfactual"). Some people might have had access to cataract surgery from other providers; these counterfactual successes must be netted out of the success we observe. Otherwise, we would be attributing a change (being cured of blindness) to the nonprofit when it would have happened anyway. Few nonprofits estimate the counterfactual themselves, so we construct our own counterfactual estimate based on research and publicly available data — namely, the percentage of the population with existing access to cataract surgery and the percentage of the population with existing access to essential health services.

We don't know if the observed changes were caused by the nonprofit's program or something else happening at the same time (e.g. a participant got a raise). To determine causation, we take the outcomes we observe and subtract an estimate of the outcomes that would have happened even without the program (i.e. counterfactual outcomes).


Data Source

Cost data reported by Benevolent Missions International and data and assumptions about partner and beneficiary costs.

Cost Calculation

$130,045 program costs + partner costs + beneficiary costs = $130,045 total costs

After estimating the program's outcomes, we need to determine how much it cost to achieve those outcomes. All monetary costs are counted, whether they are borne by a nonprofit service deliverer or by the nonprofit’s public and private partners. In-kind donations, of labor or supplies, are not counted.


Impact Calculation

$130,045 total costs / 1,698 people cured of blindness = roughly $80 cures one person of blindness.

Numbers may not divide precisely due to rounding and time discounting.

We calculate impact, defined as the change in outcomes attributable to a program divided by the cost to achieve those outcomes.


Benchmark for Rating

Impact ratings of cataract surgery programs are based on the cost of a disability-adjusted life year (DALY) averted relative to the G.D.P. per capita of the country in which the program operates. Programs receive 5 stars if they avert a DALY for less than than the G.D.P. per capita, and 4 stars if they avert a DALY for less than three times G.D.P. per capita. If a nonprofit reports impact but doesn't meet the benchmark for cost-effectiveness, it earns 3 stars.


The nonprofit averts a disability-adjusted life year for less than the country's G.D.P. per capita.

Why We Could Be Wrong

We welcome your suggestions for improving our methodology. Our methodology section includes explanations of how we mitigate these issues.

  • The outcome could oversimplify total impact. Using “people cured of blindness” as the metric of analysis does not capture the level of health and wellbeing restored.
  • There could be multiple important outcomes not captured in our analysis.
  • Benevolent Missions International may be spending additional money in order to serve harder-to-reach and/or particularly valuable populations.
  • In the absence of better data, we assume uniform counterfactual rates for programs, at the risk of masking variation across nonprofits.
  • Our estimates rely on data made public by Benevolent Missions International on its website, annual reports, financial statements and Form 990s.
  • We only analyze programs that meet our criteria. As a result, this report may not fully reflect the impact of Benevolent Missions International.
  • We do not assess what explains the nonprofit's cost-effectiveness.

We assign a rating to the nonprofit using the rubric:

  • There are indications of governance or financial health issues at the nonprofit.

  • After being given an opportunity, the nonprofit chose not to publish impact information.

    We are not yet issuing this level of star rating.

  • The rated program does not meet our benchmark for cost-effectiveness.

  • The rated program is cost-effective.

  • The rated program is highly cost-effective.

How We Calculate Impact

This rating is based on ImpactMatters analysis of the impact of Cataract Surgery Program relative to costs. Impact is the change in the social outcomes of people served by the program, net of the change that would have happened even without the program (the “counterfactual”); divided by cost. Learn more.
