Compare a Device Purchase With Its Subscription Costs
Choose a common number of months and a currency. Give each option a separate column and record the exact device model and subscription tier.

Start with your own situation
Choose a common number of months and a currency. Give each option a separate column and record the exact device model and subscription tier.
Work through the record
Add purchase, activation and required accessories once. List monthly charges separately; record introductory expiry and any quoted cancellation charge rather than assuming a stable rate.
Your printable worksheet
Use one sheet per device and subscription comparison record. Fill these fields: Option / model / horizon / upfront / recurring periods / required extras / unknown fees. Leave missing information marked unknown; do not silently substitute an estimate.
Make the next decision
Compare the totals only after checking that both options include the functions you need. An unknown renewal price is an unresolved input, not a zero-dollar charge.
