How the calculator works

The Homeli interior cost calculator runs on real 2026 pricing data from our 312+ completed Chennai projects. The formula multiplies your home's carpet area by the tier-wise per-sq-ft rate, then adjusts by scope (full home vs partial). The result is a ±15% accurate range — wide enough to honestly reflect real variation in finish choices, narrow enough to make a real budget decision.

Cost calculator FAQ

Common questions Chennai homeowners ask about interior cost estimates.

How accurate is this calculator?

±15% accurate based on Homeli's real Chennai 2026 pricing across 312+ completed projects. Final itemised quote (after free site visit) lands within this range for typical projects. Edge cases like very tall ceilings, structural changes, or imported finishes may fall outside — we explain why during site visit.

What's included in the estimated cost?

Turnkey interior — modular kitchen + wardrobes + false ceiling + lighting + painting + sanitaryware + civil/electrical changes. Excluded: electronic appliances (TV, AC, refrigerator), custom curtains beyond standard BOQ, third-party landscaping. These are listed separately during itemised quote.

Why is there a range, not a single price?

Interior design has many variables — finish choices (laminate vs acrylic vs PU), hardware (Hettich standard vs Blum premium), brand selection, accessory count. The range covers realistic variation. The free itemised quote after site visit narrows this to your specific project.

Does cost vary by Chennai locality?

Same Chennai 2026 pricing across all Greater Chennai localities — Adyar, Anna Nagar, OMR, T Nagar, Velachery, Tambaram, Mylapore, etc. We don't add locality premium. Material logistics + travel are absorbed into our base pricing.

Is the calculator + site visit really free?

Yes — completely free, no signup required. Free site visit + itemised written quote (which converts the estimate into your final project price) is also free. 10% booking advance applies only after contract signing.

How long is the estimate valid?

The calculator uses current 2026 pricing. Itemised written quotes (after site visit) are typically valid for 30-60 days. After that, raw material costs (plywood, hardware) may have shifted slightly. We hold prices for 90 days if you sign within that window.

What if my home has unusual layout or specific requirements?

The calculator assumes a typical Chennai apartment / villa layout. Unusual shapes (slanted walls, very tall ceilings, irregular corners) can move the cost up or down by 10-25%. The site visit identifies these and adjusts accordingly. Calculator gets you in the right ballpark; site visit gets you to the exact price.

Can I get cost estimate for commercial space (office, shop)?

Yes — see our specialised commercial cost calculator at /interior-design-cost-in-chennai or browse the commercial pillar at /commercial-interior-designers-chennai. Commercial pricing: ₹650-2,400/sq ft (office), ₹950-3,500/sq ft (showroom/shop), ₹1,100-2,400/sq ft (clinic).
