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.
