Calculation method
Calculation method
Entered programme cost ($)
Direct cost+allocated overhead.
Recorded outcomes with complete follow-up
Count outcome yes only where follow-up is also yes.
Cost per complete-follow-up outcome ($)
Cost/complete-follow-up outcomes; undefined when none.
Participants with complete follow-up
Count follow-up yes independently of outcome.
Outcome rate among complete follow-ups (%)
Qualified outcomes/complete follow-ups×100; unknown when none.
Participants missing complete follow-up
Total participants−complete follow-ups, preserving the missing-data denominator.
Symbols and units
- a
- Direct programme cash cost ($)
- b
- Allocated overhead cost ($)
- c
- Participants: ID, outcome recorded yes/no, follow-up complete yes/no
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- A supplied-record cost/denominator audit, not a claim of causal impact, outcome quality or programme effectiveness. Incomplete follow-up remains visible.
