3. (banking, slang, ironic) A customer who pays their credit card or loan balance in full and on time each month, thereby incurring no interest charges. (Compare revolver, who carries a balance and pays interest.)
   • 2026 May 17, “"Deadbeat" Credit Card Users: Definition and Benefits”, in Investopedia‎, archived from the original on 14 June 2026:

     Deadbeat is slang for a credit card user who pays their balance in full and on time each month. […] A deadbeat is also called a "nonrevolver" or a "transactor." […] However, so-called deadbeats in the credit world also do not rack up bills they never pay, so they do not generate significant losses for credit card companies like real deadbeats, who do not pay their bills.
