Which Categories Belong in Cash? A Selection Rule for Envelope Categories Based on Overspend and Transaction Counts
Year: 2026
Type: article
Abstract: Paying in cash restrains spending in some categories and merely inconveniences it in others. This paper prices the choice category by category, using stated monthly spending and stated card-overspend factors (spending on card relative to the household's own intended level) across six discretionary categories, against the costs of cash: hassle valued at USD 64.80 a year per category and forgone cashback of 1%. Cash wins clearly for online impulse purchases (net USD 563.33 a year), dining (USD 711.75) and entertainment (USD 277.20); it loses for transport extras (USD -32.67) where the overspend factor is small. The selected set — dining, grocery_extras, clothing, entertainment, online_impulse — is worth USD 2093.68 a year against USD 2061.01 for cashing everything indiscriminately. The rule that emerges: cash belongs where the payment mechanism itself loosens spending, not where spending merely passes through a card. The study is computed from stated parameters, with a Monte Carlo check, and is not measured. SIMULATED, NOT MEASURED.
