reserved-instance-breakeven≈ 734 tokens
Use this when a user asks whether to buy Reserved Instances or stay on On-Demand, or how long an RI takes to pay for itself. Takes On-Demand and RI monthly costs plus optional upfront fees (0 when omitted). Judges the 1-year and 3-year terms separately and returns each break-even month and net saving. It recommends a term only when that term saves money over its own length, and prefers 3 years only when it beats three 1-year terms over 36 months at current prices.
