Implementation Cost Calculator accuracy and testing
This page documents how Calwarden builds trust for this calculator: source notes, regression-style default tests, limitations, assumptions, unit handling, rounding, and visible change history.
Formula source
- Total implementation cost = (vendor services + setup fees + internal hours * internal hourly cost + integration + migration + training + tooling) * (1 + contingency percent).
Test cases
Default input regression check
Generated from the checked-in default inputs and calculate function.
Inputs
- Vendor Services Cost: $28,000
- Platform Setup Fees: $5,000
- Internal Project Hours: 180 hr
- Internal Hourly Cost: 85 $/hr
- Integration Cost: $12,000
- Data Migration Cost: $6,000
- Training Cost: $4,000
- Implementation Tooling: $1,500
- Contingency: 12%
Expected outputs
- Total Implementation Cost: $80,416.00
- Internal Labor Cost: $15,300.00
- Base Implementation Cost: $71,800.00
- Contingency Cost: $8,616.00
Known limitations
- This page documents the checked-in calculator logic and does not certify results for every real-world edge case.
- Use the result as a planning estimate unless the calculator page states a stricter purpose.
Assumptions
- Contingency is applied to the full base implementation cost.
- Ongoing subscription, support, and renewal costs are excluded unless entered as implementation fees.
- All prices, fees, rates, and cost drivers are user-entered assumptions.
- Calculations are deterministic and run locally in your browser; Calwarden does not upload or store these inputs.
Unit handling
- Vendor Services Cost accepts values in $.
- Platform Setup Fees accepts values in $.
- Internal Project Hours accepts values in hr.
- Internal Hourly Cost accepts values in $/hr.
- Integration Cost accepts values in $.
- Data Migration Cost accepts values in $.
- Training Cost accepts values in $.
- Implementation Tooling accepts values in $.
- Contingency accepts values in %.
- Total Implementation Cost is displayed as currency.
- Internal Labor Cost is displayed as currency.
- Base Implementation Cost is displayed as currency.
- Contingency Cost is displayed as currency.
Rounding rules
- Number displays use up to 2 decimal places in the calculator UI.
- Currency outputs are displayed with standard US dollar formatting.
- Input precision follows configured step values where provided.
