You can look in the spreadsheet, but I said sessions are 25 minutes, and there are 8 session per weekend including Friday testing (so 3.33 hours per weekend), and 8 weekends per year (26.67 hours on track per year).

I had started with 10 sessions per weekend, and 10 weekends per year, but I got feedback that while that was certainly possible, it wasn't common. So I reduced both.

If this doesn't match your plans, you can use the per-hour data in the spreadsheet to create your own per-weekend and per-year costs. Keep in mind that this data only covers items that differ significantly between classes, and comes nowhere near covering all the expenses in a year of racing.
