A meal-planning app offers $59.99 a year or $7.99 a month. Break-even is month 8 ($59.99 ÷ $7.99 = 7.5, rounded up). The yearly plan feels like the disciplined choice in January.
By April the cooking routine has slipped. Four months of monthly would have been $31.96, so the yearly plan cost $28.03 more than the months it was used. Next January, it renews at whatever the price is then, unless someone remembers to check.
