How do you and your au pair keep track of her personal use of your shared car, so that she pays for her own gas while you pay for the gas used when she’s on duty?
I must admit, I’ve had the luxury of (most times) having a third car that was pretty much only used by our au pair. She was responsible for the gas herself. When I (rarely) needed to use that car instead of my own (like when I just didn’t want to move it out of the driveway just to go to Quick Chek), I’d leave a few dollars in the console, or put some gas in myself.
Sometimes we have that luxury of a whole separate "au pair car", other times we just give up and pay for the au pair’s personal use of the car (when times are flush, gas prices are low, and she doesn’t’ drive much anyway). But what about the in-between? What advice do you have for Maya?
As Maya writes:
I have tried to estimate how much driving will be needed for my kids in order to give her gas money at the beginning of the month for kid’s driving and the rest would be her costs, but it fluctuates so significantly that I have no idea on how to even approach this.
I mean, there are seriously months where there would less then 100 miles of kid driving required, it was the case with October and November, and now December, and some moths where that would be close to 400 miles, which will be January, March, and April. February and then May and on, there will be barely any driving at all, so we are back to about 60-70 miles per month.
It would feel strange to me to keep giving her different amounts for gas every month, but then as gas prices fluctuate, the gas money would fluctuate too, so may be this is not that strange at all.
Has anyone had success using a mileage log? Or a trip odometer? Do tell!
