How to use the Equivalent Annual Cost Calculator

Operating costs occur at each year end and salvage at the final year end. The annuity factor converts all entered costs to a common annual basis.

The calculation

PV = purchase + annual×annuity factor − salvage/(1+r)^n; EAC = PV/annuity factor

Worked example

$10,000 purchase, $1,000 annual operation and $2,000 salvage over five years at 0% give $2,600 equivalent annual cost.

Assumptions and limits

Assumes constant operating costs and a known useful life. Does not model unequal replacement cycles, taxes or uncertainty in resale value.
