There are too many variables to rely on mileage as a metric. Lubrication, grit, condition of cogs, water, applied stress, etc. all contribute to chain wear. I bought a go/no-go gauge from Park,

If the tool fits, then it's time to replace. The tool can be easily used when it's on the bike. I think it cost under $10. Or you can measure as described above.
