  • Cash stuffing, an old-school budgeting trick, is gaining popularity among young people on TikTok.
  • Roxanne, 27, said cash stuffing has been instrumental in helping her pay off her credit-card debt.
  • But this budget system isn't a good fit for everyone because it can be time-consuming.

In July 2021, Roxanne Macias said she was living paycheck to paycheck, didn't have a savings account, and was racking up credit-card debt. 

"I spent my 20s maxing out credit cards that I did not understand," the 27-year-old told Insider.
