Malaria Nets

Malaria still kills a child about every minute. Almost every one of those deaths is preventable.

$30five netsfive nets

Malaria Medicine

Malaria has a season. Most child deaths from it fall in a few predictable months.

$35five children through the seasonfive children

Childhood Vaccines

The vaccines are free. The infants who miss them have parents who couldn't afford the trip.

Child Survival

Most child deaths come from causes we already know how to stop, cheaply.

Malnutrition

Severe malnutrition is treatable in weeks, if the clinic can afford to keep running.

Safe Water

A chlorine dispenser at the spring people already walk to, and the water they carry home stops making children ill.

Syphilis in Pregnancy

A treatable infection, caught at a routine appointment, is the difference between a stillbirth and a birth.

Animal Welfare

Most hens in the world live in a cage the size of a sheet of paper. That is changing, company by company.

Why Ripple Good?

Doing the most good for every dollar.

Not all charities are created equal. Two organizations working on the same problem can differ enormously in how much good they do with the same dollar, and the difference is rarely the thing people look at.

  1. AmountHow much you give. This one is obvious, and it's the only one most people think about.
  2. EfficiencyHow tightly the organization runs: program spending versus overhead, the cost to raise $100. This is what Charity Navigator and CharityWatch largely measure. It answers a real question, but says nothing about whether the programs work.
  3. ImpactWhat a dollar actually buys: lives saved, children protected, years of schooling gained. This is what GiveWell and Animal Charity Evaluators measure through randomized trials and outcome research, and it is where the differences get enormous.

The public conversation is dominated by the second one. Nearly all the real-world good comes from the third, where the best options can be on the order of 100x the median, an order-of-magnitude claim that is sourced and qualified on the methodology page.

That gap is why Ripple Good exists. Rigorous impact research is scattered across separate evaluators, each covering its own corner of the world, and almost none of it reaches the person deciding where to send $50 at the end of the year. We pull the best evidence-backed picks together across every major cause: global health, extreme poverty, child nutrition, animal welfare.

The ripple is the part you don't see: the child who doesn't get malaria doesn't miss school, and the effect keeps spreading long after the gift.

Methodology

How a pick gets made, and what our figures mean.

We don't run the research. We translate it. GiveWell and Animal Charity Evaluators spend years on questions we could never answer alone, so every pick here names the evaluator behind it, shows the real cost figures, and says what could be wrong with them.

Every dollar figure is an average program cost, not a promise about your particular gift. Charities pool donations; the figure is what it has cost, on average, to produce that outcome.
