Stop comparing
$2,400 to $8,500.
Sticker prices lie. The only honest comparison divides total cost by total years — and once you do, the answer is sometimes the opposite of what you thought.
Repair looks 71% cheaper on the sticker — but at $400/yr vs $425/yr, the gap is razor-thin and tilts on remaining life.
Which components cost the most per year?
Cost-per-year reshuffles the rankings. The cheapest sticker isn’t always the cheapest annualized — and the most expensive replacement might actually be the bargain.
The math, four lines.
Subtraction, addition, division. No discount rates. No surprises.
The lower per-year number wins — but the verdict engine also weights remaining life, condition, and ROI before declaring a winner.
