The company Cane Island Digital Research (CIDR) did an investigation on the amount of BTC that is lost daily and according to its estimates these were the results:
Every day 1,500 BTC are irreversibly lost.
Every day on average 900 BTC are mined.
According to these calculations, the current BTC supply is 25% less than what has been mined to date, that is, 18.5 million have been mined and there are only 13.5 million circulating.
For Coinmetrics there are only 1.5 million BTC lost.
To all this Satoshi Nakamoto added that the lost coins are profit for others.
