Door Total Cost of Ownership
The cheapest door is rarely the cheapest to own. Add maintenance, lifespan and replacement risk over 10–20 years and the real cost — an honest ₹/year — can flip. Compare up to three doors for Indian homes, including wet and coastal use.

Assumptions: TCO = upfront (all-in, incl 18% GST) + annual maintenance × years + amortised replacements. Replacements combine wear-out (a door rated for fewer years than your horizon is re-bought, fractionally amortised) and a probability-weighted mid-life failure that rises with humidity and coastal salt air. Lifespans, maintenance and risk are indicative India 2026 figures — verify by city, grade, brand and warranty before you buy.
