The Ministry of Defence paid out £688,000 for 289 civilian deaths between 2006-14, an average of £2,380.
But in one case, a family was paid just £104.17, less than others received for the deaths of a herd of donkeys.
The MoD said compensation was set by legal principles, including past and future losses and local customs.
Almost 7,000 compensation claims paid out by the British military during combat operations in Helmand, in Afghanistan, up until 2014 were analysed by the charity Action on Armed Violence (AOAV).
