Should I replace it now, or should I keep using it?
"Bwabakrae" is an app that calculates when it is most cost-effective to make a replacement.
■ For those who:
· My car is 10 years old, but repair costs keep piling up. Is it right to replace it now?
· My phone battery is at 80%; should I buy a new phone or just replace the battery?
· My refrigerator is old; is it more economical to replace it because of the repair costs?
■ How it works:
The newer an item is, the faster its value depreciates, and the longer you use it, the higher the repair and electricity costs become.
"Bwabakrae" calculates the total cost for every year starting this year and identifies the year when the two factors reverse. · Recommended Timing: Within this range, the timing is similar regardless of when you change.
· Best Year: The year with the smallest total cost.
· Year to Avoid: Losses increase significantly after that.
■ Five Product Categories
Automobiles · Smartphones · Laptops · Large Appliances (Refrigerators, Washing Machines, Air Conditioners, TVs) · Motorcycles
■ Basis-Based Calculation
Calculations are based on publicly available data, including the Ministry of the Interior and Safety's vehicle residual value notification, the parts retention period under the Consumer Dispute Resolution Standards, the Korea Consumer Agency's appliance failure statistics, and manufacturers' official OS support policies.
The assumptions used in the calculation are displayed on the screen.
