Formula and units
Annual A = price × frequency × periods (365, 52, 12 or 1). Monthly = A/12. Year y = A × (1 + growth/100)^(y−1). Total sums the years; growth 0 gives N × A.
Scope
Growth is nonnegative. Comparisons spread the initial frequency evenly across days: 365 days, 366 days, 364 days (52×7) and 260 weekdays (52×5). These are counting scenarios, not real calendars. Spending is not net savings from stopping; replacement costs, discounting and investment returns are excluded.
