Coinhive estimates that a user with a mid-range laptop would have a hashrate of 30 h/s. 10 minutes of mining = 30 * 10 * 60 = 18,000 hashes Since Coinhive pays out 0.000090 XMR per million hashes (current rate as of Dec 11. 2017), that's $0.0004250394 per user (18000/1000000 * 0.000090 * 262.37). In order to make $1, you would need 2,353 visitors with laptops mining for 10 minutes each.
