I have as much if not more in accessories than I do my bike, and my bike was $800.
Bike carrier for the car, bike rack, bag to put on the rack to carry tools, tube, tube repair kit, and extra water. Tools to maintain and repair the bike. Fenders, water bottle holder, water bottles, upgraded pedals, mirror, extra chain, chain cleaning products, small crock pot, and wax for chains, lights, wahoo element bolt computer, speed, cadence, and heart rate sensor, different set of tires because I didn't like the ones the bike came with. The cost of hotel rooms for my extended bike trips to different trails. Donations to different organizations for maintenance of rail trails. Just recently tools to tension spokes and align wheels. I'm sure I missed a few expenses. So after giving it some thought the bike was the cheap part of my biking experience.
