Sprocket and chain ring are still like new. So I reckon I have saved a small fortune in money and time not to have to maintain a derailleur system any more. Initial cost of Rohloff is high but it soon pays for itself before you even consider the benefits of riding with it over a derailleur transmission
But that depends on mileage and effort expended. As noted above, the time I spend on maintenance and cleaning is minimal, I use the 'plenty of oil' (or wax in my case) regime and have full length + long mudflap guards attached. The bike is not high mileage, my commute is 3 miles each way in noncovid times, plus other utility riding, occasional leisure/overnight camping tours totals perhaps 2000-3000 a year. That's a chain every 2 years and the time to change it and a cassette & middle chainring change every 4 or 6. Works out to approx a bit over £50 maybe 90min of my own labour if I'm particularly slow every 4 years.
If I was after a high mileage bike (or lived in a flatter area) and perhaps less likely to leave it locked up outside in central areas on occasions then I can certainly see the case for going for a more expensive IHG & belt.
