Heres a quick break down of expenses per day. Truck .80$ per mile x 50 miles = 40$ Mower 8$ per hour x 5 hours = 40$ Handheld and misc = 10$ So basically on a 300$ day expenses are around 1/3. That's 100$ so I would net 200$ for the day. Taxes will kill off at least 1/3 of that so in my pocket a 300 $ day is actually around 150$ in real income. If you don't know your expenses its possible your working for literally nothing.
