The disclosed TCO formula
One-off integration and training are added to monthly user licences, API or additional tools, internal operating hours and external support. Monthly cost is multiplied by the selected assessment period.
How to compare fairly
- Use the same period and user count for every option
- Enter internal administration, quality assurance and governance as hours
- Use only verified prices and record the plan date
- Assess benefits separately against a measured process baseline
What the result does not claim
The calculation is a transparent planning estimate, not a quotation or return guarantee. Procurement, legal review, migration, taxes and unlisted third parties must be added where applicable.
Decision matrix
| Cost block | Type | Evidence to check |
|---|---|---|
| Integration and training | one-off | scope and statement of work |
| Licences and API | monthly / consumption-based | current plan and usage assumption |
| Operations and support | monthly | roles, hours and service scope |
