How to use this calculator
Enter comparable benefits and costs per period, then choose whether to value time saved.
Formula and method
Net value = (benefit − cost + valued time saved) × periods. Opportunity cost of A = max(0, B net value − A net value).
Worked example
Defaults: A net 24,000 USD, B net 30,000 USD over 12 periods; opportunity cost of A is 6,000 USD.
Assumptions and supported scope
Undiscounted scenario comparison. No risk adjustment or proof that time savings convert to cash; use comparable assumptions.
