If high school, I typically go with age, then an additional dollar for more than 1 child. So, if $16 and I have 3 kids, I add two additional dollars= $18 per hour for three kids. I’m honestly so happy to have good babysitters I always add a little extra in the Venmo and just round up. Date nights are so freaking expensive with this mindset, but I do it’s just cause I want them to come back 🫣
If it’s someone where this is their livelihood- such as a nanny or someone older, then typically they negotiate rates from $20-$25+.
