Door Total Cost of Ownership

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.

Horizon

Salt air + damp — cheap doors fail fast; risk peaks. Lowest sticker price. Swells and delaminates in damp / coastal air; short life. Costs are all-in per door (supply + frame + fitting + 18% GST), India 2026 — varies by city, grade and vendor.

Over 15 years in wet / coastal use, the cheap door costs 25,454 MORE than WPC — the low sticker price is a trap here.

How the cost builds up over time

Cumulative spend year by year. A cheap door starts low but climbs steeply each time it has to be replaced — watch where the lines cross.

Buy the door that's cheapest to own

DesignAI weighs material, climate and use against lifetime cost — so you avoid the cheap door that quietly costs more, especially in wet and coastal homes.

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.
