The Egyptian pound has lost half its value against the dollar since March, following a devaluation demanded as part of a $3 billion International Monetary Fund loan agreement.
Official annual headline inflation hit 21.9 percent in December, and food prices surged 37.9 percent in the Arab world's most populous nation.
But Steve Hanke, an economist at Johns Hopkins University who measures inflation based on purchasing power parity and factoring in black market exchange rates, estimated Egypt's real inflation rate at 101 percent.
According to the World Bank, nearly one-third of Egypt's 104 million people already live below the poverty line, and almost as many are "vulnerable to falling into poverty".
"It's like we were hit by an earthquake, suddenly you have to let go of everything," said Manar, a 38-year-old mother of two.
The economy, dominated by state and military-owned enterprises, had already struggled after successive blows, from years of political unrest to the Covid pandemic.
But it was Russia's invasion of Ukraine -- with both countries key exporters of wheat and sources of mass tourism to Egypt -- that set off the latest painful crisis.
The war also unsettled global investors who pulled billions out of the North African country.
Since prices began spiraling again last year, social media users have scrambled for cost-saving tips, suggesting grocery list substitutions and personal finance maneuvres.
But for a 41-year-old translator who is the mother of a six-year-old son, and who asked not to be named, even "military-grade discipline" in the supermarket is no longer enough.
With her husband's salary "losing 40 percent of its value in six months", she also worries about expenses "like mortgages and car payments and tuition".
The new reality has driven families that were considered part of the middle class to seek help.
Ahmed Hesham of the Abwab El Kheir charity said more and more middle-class Egyptians -- "private sector employees making 4,000-6,000 pounds" ($135-202) per month -- have been coming in for donations.
"A lot of people had life savings they were keeping aside... Now they're using them for health care or daily costs," Hesham told AFP.
"They used to make a good living, now they can't make ends meet. They've never been in this position before, and they're mortified to come to us," he added.
"One man told us he can either feed his kids or put them through school, but not both."
For educated Egyptians, said the translator, "the only solution is to find a job abroad. I can't see another way out."
Many young Egyptians have flocked to online sites advising them on job opportunities in wealthy Gulf countries, or on how to have their degrees recognized in Europe.
Those who can try to join the millions of Egyptians already abroad, who sent back $31.9 billion in remittances in the 2021-2022 financial year.
Many families who can't move away, like Manar's, focus on education to improve their opportunities.
With Egypt's public school system marked by notoriously overcrowded classes and outdated curricula, private education is a priority for families who can afford it.
"The schools are a disaster," Manar said, forcing families to pay 20,000-40,000 pounds ($675-1,350) per year for basic elementary schooling.
"You have to be ready to sell everything you have to give your kids an education, in hopes that tomorrow things will be better for them."
But, she said, "the problem is that we don't know if this is as bad as it gets.
"The way things are, all you can do is take it one day at a time."
