While the www.doge.gov site isn't showing savings yet (it was supposed to be by Valentine's Day, then by over the weekend, but still nothing,) I've seen estimates of savings of $1,000,000 every 22 seconds. What this means, given a population estimate of 345 million:

DOGE is saving $163,636,363 every hour. DOGE is saving $3,927,272,727 every day. That is $11.38 for every man woman and child in the US. DOGE is saving $117,818,181,818 every month. That is $341.50 for every man woman and child in the US. Account for interest saved on that money over the rest of each of those individual's lifetimes, you have a TON of savings. And Musk is just getting started!
