Repair or Replace? Compare Annualized Cost, Risk and Downtime
The size of a repair bill is not the decision by itself. Compare the cost per expected year of restored service with the net annualized cost of a replacement.
Repair vs. Replace Calculator
Put two imperfect options on an annualized cost basis without counting sunk cost.

Put unequal useful lives on one annual clock
A small repair and long-lived replacement cannot be compared by upfront price. Annual cost exposes the time each path buys.
- Estimate life added by repair
- Estimate replacement life
- Compare annual cost and risk
Annualized cost of each path

Use a diagnosis, itemized repair quote, installed replacement quote and realistic life range.
How unequal useful lives are compared
Repair annualized cost divides repair plus expected follow-on cost by added life. Replacement annualized cost subtracts salvage and operating savings over expected life before dividing by years.
Why reliability remains a judgment
Safety, downtime, uncertain failures, financing and non-financial performance can override the simple annualized comparison.
This calculator supports The Real Cost of Ownership. Repair or Replace? Compare Annualized Cost, Risk and Downtime explains which details can change the inputs. The calculation methodology shows how we handle timing, rounding and exclusions.
Evidence standard for this calculation

Which option has lower annualized incremental cost?
The lower annualized option spreads repair risk or replacement net cost over the useful life each choice is expected to deliver.
How much added life must a repair deliver to break even?
Break-even added life is the repair cost divided by the replacement option's comparable annual cost, adjusted for follow-on costs and operating savings.
Condition and service evidence to gather
- Safety, downtime and follow-on failure risk
- Installation, disposal and operating-cost differences
