How this calculator works
Remaining scenarios = applicable scenarios − capped accepted scenarios. Accepted percentage = accepted ÷ positive applicable count × 100. Effort = remaining scenarios × execution/review minutes ÷ 60 + separate fixes hours. Time value = effort × engineering cost.Worked example
Eleven accepted scenarios out of 18 gives 61.11% completion and seven remaining. At 30 minutes each plus four fixes hours, effort is 7.5 hours, valued at 562.50 at 75 per hour.Assumptions
Defaults are illustrative. Replace them with your own measured quantities and documented assumptions. Use matching periods and a consistent currency wherever monetary amounts are entered.Interpreting your results
This does not send webhook requests, inspect endpoints or validate security. Coverage depends on the scenarios you define and the evidence you record. A completed plan is not proof that every failure mode is covered.Calculation formulas
- remaining
MAX(required-MIN(passed,required),0)- hours
remaining*minutes/60+fix- Tests completed and accepted
SAFE_DIV(MIN(passed,required),required,0)*100- Unfinished or failed critical tests
MIN(critical,remaining)- Cost to finish testing and fixes
hours*rate- Engineering hours still needed
hours
Frequently asked questions
What should I check before using the result?
Use your integration’s documented requirements to cover relevant delivery, retry, duplicate, ordering and failure cases. Record the expected result and observed evidence for each case before marking it accepted.
Does this tool connect to my records?
No. This is a local calculation from the figures you enter. It does not scan accounts, import private records or verify legal, regulatory or exam requirements.
