Cloud Migration Cost Planner 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

  • Monthly run rate = compute + storage + egress. First-year cost = 12 months run rate + migration labor with contingency.

Test cases

Default input regression check

Generated from the checked-in default inputs and calculate function.

Inputs

  • Workloads: 18
  • Compute per Workload: 220 $/mo
  • Storage: 24 TB
  • Storage Cost per TB: 28 $/mo
  • Monthly Egress: 6 TB
  • Egress Cost per TB: $90
  • Migration Labor: 240 hr
  • Labor Rate: 115 $/hr
  • Contingency: 18%

Expected outputs

  • Monthly Run Rate: $5,172.00
  • One-Time Migration Cost: $32,568.00
  • First-Year Cost: $94,632.00

Known limitations

  • This workflow is a planning aid. Validate assumptions, rates, legal/compliance obligations, vendor quotes, and local policies before acting.

Assumptions

  • All values are user-entered planning assumptions.
  • Calculations run locally in the browser.
  • Saved artifacts are stored only when a signed-in user explicitly saves them.

Unit handling

  • Workloads accepts numeric values.
  • Compute per Workload accepts values in $/mo.
  • Storage accepts values in TB.
  • Storage Cost per TB accepts values in $/mo.
  • Monthly Egress accepts values in TB.
  • Egress Cost per TB accepts values in $.
  • Migration Labor accepts values in hr.
  • Labor Rate accepts values in $/hr.
  • Contingency accepts values in %.
  • Monthly Run Rate is displayed as currency.
  • One-Time Migration Cost is displayed as currency.
  • First-Year 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.
