The United Nations' Palestinian refugee agency has described the financial needs as "unprecedented" ahead of the Cairo meeting, which follows the Strip's third war in six years.
But it is unclear how generous the world is willing to be given the intractability of the Israeli-Palestinian conflict and other priorities in the region such as the fight against jihadists in Syria and Iraq.
About 50 countries will be represented in Cairo for talks that will include UN Secretary-General Ban Ki-moon, US Secretary of State John Kerry, 30 foreign ministers and various international monetary and humanitarian bodies.
Other estimates suggest up to USD 8 billion will be needed to repair damaged infrastructure and homes, and ensure healthcare, education and clean drinking water.
The bloody 50-day conflict between Israel and Gaza militants left almost 2,200 Palestinians dead along with 73 on the Israeli side.
The war, which ended with a ceasefire on August 26, also left 100,000 Gazans homeless.
More than a quarter of the Strip's population of 1.7 million was displaced.
Even so, a Western diplomat, speaking on condition of anonymity, warned there was "considerable donor fatigue."
Money raised in Cairo will also go towards getting Gaza's economy back on its feet.
Gross domestic product (GDP) is expected to be down 20 per cent in the first three quarters of 2014 compared with the same period last year.
Unemployment stood at 45 per cent before the war, and 63 per cent among young people who make up a large part of the population.
Without immediate action to revive the economy, a return to violence "will remain a clear and present danger," the World Bank's Palestinian territories director Steen Lau Jorgensen warned last month.
