Formula used
Monthly alternative cost:
Let S_i be the monthly price of service i and D_i the annual discount rate (0–100).
Discounted monthly = S_i × (1 − D_i / 100).
Let T be tax/fee rate (0–100).
Taxed monthly = (Σ discounted monthly) × (1 + T / 100).
Let C be one‑time device cost and A the amortization months.
Device monthly = C / A.
Alt monthly = Taxed monthly + Device monthly.
Totals and savings:
Let H be the time horizon in months and M_cur the current monthly cost.
Current total over H = M_cur × H.
Alternative total over H = Alt monthly × H.
Savings over H = Current total − Alternative total.
Break‑even months (if Alt monthly < M_cur) = max(0, C / (M_cur − Alt monthly)).
If Alt monthly ≥ M_cur, there is no break‑even within the horizon.
