Lifecycle Cost Calculator

Discount recurring operating, maintenance and replacement costs to present value.

How to use this calculator

Present-value analysis places costs occurring in different years on a common date. Compare alternatives using the same analysis period, service level, rate convention and cost boundary.

Enter assumptions and calculate.

The model assumes annual costs occur at year-end and remain level. It does not separately model inflation, tax, depreciation or financing.

Interpret the result

Review the result as a scenario, not a verified estimate. Test the assumptions that matter most, record the date and currency basis, and reconcile the calculator with the project’s formal estimate and approval process.
