Useful next steps
Compare the complete ownership period
Enter repair and replacement costs, annual operating costs and the expected life of a new replacement. Choose shorter, expected and longer successful-repair lives, then a shared horizon.
See how assumptions change the result
Enter the chance that repair succeeds and an annual discount rate. Failure means paying for the repair and then replacing immediately. Optional end-value credit uses remaining replacement life, not an invented resale price.

Download CSV and a text or JSON report. The calculation runs on your device. Changing a unit keeps the number you entered, so check both before using the result.
