Have you ever angsted over how much to pay your babysitter? I always find myself wondering if I've hit the right mark. Turns out I may be paying a little too much.

Sittercity, the online service that helps babysitters and parents find each other, has a rate calculator that I just stumbled upon over at Kid Baltimore. It's pretty neat. You put in your zip code, the age of the sitter, and the number of kids you have. Then the calculator spits out a per-hour rate.

For my zip code, with 2 kids and a sitter 18-21 with less than a year of experience, it said I should be paying $12 an hour.

The only downside is that it didn't appear to have a field for a younger babysitter. Would you pay less for a high-schooler?
