How to Use This Calculator

Select the Appliance Type (refrigerator, washer, HVAC, etc.) to load the typical manufacturer lifespan range.
Enter Age Years for the appliance and select Usage Level (light, normal, or heavy) to adjust remaining life.
Input Repair Cost for the current issue and Replacement Cost for a comparable new model.
Review Expected Lifespan and Years Remaining to understand how much useful life is left.
Check Repair Value Score — a score above 50 generally favors repair; below 50 favors replacement.
Use the Recommendation output to make the repair-or-replace decision with confidence.

How the result changes with Current Age

Current Age	Years Remaining
4	11 years
14	1 years
26	0 years
36	0 years

What each input means

Appliance Type: 0 = Refrigerator, 1 = Washer, 2 = Dryer, 3 = Dishwasher, 4 = Oven/Range, 5 = HVAC System.
Current Age: How many years old the appliance is.
Repair Cost: Estimated cost of the current or upcoming repair.
Replacement Cost: Cost of a new equivalent appliance including installation.
Usage Level: 0 = Light (1-2 person household), 1 = Normal (3-4 person), 2 = Heavy (5+ or frequent use).

What each result means

Expected Total Lifespan: Average total lifespan for this appliance type adjusted for usage.
Years Remaining: Estimated remaining useful years before the appliance needs replacement.
Repair Value Score: Ratio of repair cost to remaining appliance value. Above 1.0 means repair costs more than the remaining value.
Recommendation: 0 = Repair, 1 = Consider Replacing, 2 = Replace. Based on the 50% rule and remaining lifespan.
