Reuse follows a parallel of Amdahl's law.
Long-term marginal cost is determined by the nonreusable component cost + minimum refurbish & refit costs per launch. Effectively, the benefits of reuse offer diminising marginal benefit per reuse. Though designing for long-term use (say, a personal automobile vs. a rocketship) can still make sense.
An automobile used for daily commute with a 5 year life sees ~1,000 re-uses. You can vary the parameters to get different results. There are fuel, maintanance, garaging/parking, tax/registration, and insurance costs as well.
