Kitchen, wardrobe, tile, paint or full-home — each calculator answers a different question. Here's which one to use for yours.
25 Sept 2026
Velmore runs seven free calculators — full-home, kitchen, wardrobe, tile, paint, and EMI — and each one answers a different question. Using the wrong one is the most common reason online estimates feel off.
Search for "modular kitchen cost calculator" or "wardrobe cost calculator" and you'll find plenty of generic tools that ask for a room dimension and spit out a number with no context for what that number actually includes. That gap — a calculator that gives you a figure without explaining what drives it — is exactly what causes homeowners to distrust online estimates and go straight to negotiating blind with a contractor instead.
This guide walks through every calculator on this site, what each one is actually built to answer, and — more importantly — when a calculator is the right tool and when you genuinely need a real quote instead.
The home interior price calculator is built for one question: "If I'm doing my whole 1BHK/2BHK/3BHK, roughly what am I looking at?" You enter your BHK type, size, and the package tier (budget, mid-range, or premium), and it returns a full-home range covering every room together — not just one component.
This is the right starting point if you haven't decided yet which rooms to prioritise, or if you're trying to size your total renovation budget before talking to anyone. It is the wrong tool if you already know you only want a new kitchen or a new wardrobe — for that, the room-specific calculators below give a tighter, more useful number.
The kitchen price calculator is the one to use for "modular kitchen cost calculator" style questions. It asks for your kitchen's shape (straight, L-shape, U-shape, or parallel) and dimensions, then estimates cost based on cabinet run length — which is the actual cost driver for modular kitchens, far more than floor area.
A straight 8-ft kitchen and a U-shaped 8x8 kitchen occupy similar floor space but need very different amounts of cabinetry, which is why a generic per-sq-ft number is usually wrong for kitchens specifically. If you want the fuller cost breakdown behind the number — labour, hardware brand, countertop material — the modular kitchen design cost guide covers that in detail.
The wardrobe price calculator answers the "wardrobe cost calculator" and "fitted wardrobe price calculator" style searches directly. Enter your wardrobe's width and height, choose modular or carpenter-made, and it estimates cost based on shutter area — the dimension that actually scales with hardware and material cost for wardrobes.
This is also the fastest way to sanity-check a carpenter's quote: if a local carpenter is quoting a price wildly below what the calculator shows for the same dimensions, that's usually a sign of thinner board, no branded hinges, or both — worth asking about directly rather than assuming it's just a better deal. For the full modular-vs-carpenter cost comparison, see our modular wardrobe design cost guide.
The tile calculator and paint calculator are narrower tools, built for exactly one material each. Enter room dimensions and they estimate quantity and cost for flooring tiles or wall paint respectively — useful when you're pricing a single-material job (a flooring redo, a fresh coat of paint before a sale or rental) rather than a full room renovation.
These are the calculators worth using when a contractor's tile or paint line-item looks suspiciously high or low — you can check the material quantity math independently in under a minute.
The EMI calculator is different from the rest — it doesn't estimate project cost at all. Once you have a total figure from any of the other tools (or a real quote), this one converts that lump sum into a monthly payment based on tenure and interest rate, so you can see whether a ₹15 lakh project actually fits your monthly budget before committing to it.
Honestly — accurate enough to plan with, not accurate enough to sign a contract against. Every calculator on this page uses average market rates for Delhi NCR, and averages by definition don't capture your specific apartment: whether your walls are perfectly straight, whether your existing electrical and plumbing need rework, or which exact hardware brand you end up choosing.
Treat calculator output as a planning range, not a quote. The gap between a calculator estimate and a final signed quote is usually 10-20% in either direction once a designer has actually seen your space — which is a normal, expected gap, not a sign that either number is wrong.
A calculator is the right tool when you're still in the exploring phase — comparing whether a 2BHK or 3BHK renovation fits your budget, or deciding whether to go modular or carpenter-made before you've picked a designer. Use these signals to know when it's time to move past the calculator stage:
Once any of those apply, a calculator has done its job — the next step is a real site visit and an itemised quote. You can get in touch for that, or take the interior style quiz first if you're still narrowing down a design direction.
A few patterns show up repeatedly when homeowners use these tools, and each one leads to a number that looks wrong when it's actually the calculator working correctly — just misapplied.
Avoiding these isn't about using the tools more carefully — it's about knowing which question each calculator is actually built to answer, which is exactly what the breakdown above covers.
There isn't one "best" interior design cost calculator — there's the right calculator for the specific question you're actually asking. Full-home budget questions belong on the home interior price calculator; kitchen and wardrobe questions get much sharper answers from their dedicated tools; and once you have a real number, the EMI calculator tells you if it fits your monthly budget.
Use them in whichever order matches your own decision process, and treat every result as a starting point for a conversation with a designer — not a final number.
