Repeat purchase rate28.33%

Repeat customer count340

One-time customer count860

Total customers used1,200

340 repeat customers out of 1,200 total customers gives a repeat purchase rate near 28.33%.
860 customers in this simple view bought only once during the period basis used here.
Use the result as a practical retention-style check only, because cohort timing, subscription models, and customer definitions can all change the meaning of the rate.

This is a simple customer-behavior metric, not a full retention analysis. The result depends on how repeat customers are defined and the period being measured.
