Currently it's about $0.85 USD to send ETH or $2.50 USD to send ERC20[1]. Most people will suggest not using a L1 as a payment system, but instead something application-specific like a rollup or state channel. In Ethereum those will be in the range of 5 - 20 cents per transaction[2], and may be much lower after EIP-4844[3].
Other non-Ethereum blockchains and L2s have similar range of low fees.
