The cost obviously depends on the exact format and how fuel efficient your car is. Our last trip was 5 days, two of them on the 'ring, and I spent around 600 quid.
Budget £100 for the crossing, £60-70 per night for food and lodgings, £40 for 5 laps of the ring, £15 for a session of karting. Fuel-wise, it's a 1000 mile round trip, so work it out for your car.
With regards to the crossing, it's around £100 for the tunnel and £50 for a ferry. The extra £50 is money well spent IMO, as the tunnel is so much easier. Considering this extra will be less than a tenth of the overall trip cost, it's hardly a big deal.
