Five-year software decision

Cost or constraint

Subscription: $24/month = $1,440 before price increases

Timing or value

Perpetual license: $650

Cost or constraint

Paid upgrade in year three: $250

Timing or value

Owned five-year cost: $900

Cost or constraint

Subscription may still be worth $540 if support and cross-device service are genuinely used

Keep the time period, usage and exit point consistent across both choices.

Compare the alternatives on equal terms

Define service equivalence

Cloud storage, support, collaboration and upgrades may differ. Price only features the decision-maker expects to use.

Renewal and escalation

Use current renewal terms and run price-increase scenarios. Introductory annual pricing is not a five-year cost.

Exit and data portability

Export formats, storage, device locks and retraining create switching costs. Verify what remains usable after cancellation.

Residual and obsolescence

Physical purchases may retain resale value; software licenses can lose compatibility. Ownership does not guarantee indefinite usefulness.

This decision belongs in The Real Cost of Devices and Appliances. Use Subscription Hardware: Find the Buyout, Lock-In and Renewal Cost to check the next assumption, then test the numbers in the Subscription Cost Calculator.

Before comparing renewal payments with a purchase, set one total-cost-of-ownership boundary for service life, support and exit value.

Make both options comparable

Match the same usable service and time period. A subscription may include support or upgrades, while purchase may retain resale value and impose separate maintenance, so neither headline price is complete. Record benefits that differ, but do not assign a dollar value unless the benefit would change what you buy.

Values to align before comparing

  • Renewal price, increase rules and cancellation terms.
  • Purchase price, support, upgrades and maintenance.
  • Expected resale, migration and switching costs at exit.
  • Choose the period the function is needed.
  • Match included service and support.
  • Model renewals and plausible price changes.
  • Add exit, migration and upgrade costs.
  • Subtract defensible resale or retained-license value.

Where the comparison stops being fair

  • Comparing one subscription month with full purchase price.
  • Assuming perpetual means supported forever.
  • Ignoring required cloud storage or accessories.
  • Valuing features that will not be used.

Questions this decision usually raises

When does buying break even?

Divide incremental purchase cost by avoided subscription cost, then adjust for upgrades, support and resale.

Should future subscriptions be discounted?

For long horizons, yes if a consistent disclosed discount rate is used.

What if cancellation is easy?

Flexibility has value when usage is uncertain; compare shorter scenarios instead of assigning an arbitrary premium.
