What are you planning?
At ₹1,500 to 2,500 per sq ft (rates as of Jul 2026), before land, approvals, interiors and the boundary wall.
Estimate my house cost →Four questions from a house build
Each one has a page that answers it with your own numbers.
The contractor says ₹22 lakh for 1,000 sq ft. Is that fair?
You get a cost range for your quality tier, split into structure, finishing and services.
Check the cost →I can't tell if the cement figure on the estimate is padded.
You get thumb-rule bands per sq ft to hold the engineer's quantities against.
Check the order →A sand truck just pulled up. Is it really one brass?
You get the inside-the-body measurement and the cft to brass sum.
Measure the truck →The electrician wants a bigger MCB for the AC.
You get the MCB size from the nameplate current, and the wire to match.
Read the nameplate →Start from where you are

Five worked answers from the site
The numbers come from the calculator, system and guide pages they link to.
What 1,000 sq ft costs to build, by finish
The same house lands anywhere from ₹12 lakh to ₹45 lakh depending on the finish. Pick the tier first, then compare quotes inside it.
The material order for one 1,000 sq ft floor
Check your engineer's quantities against these thumb rules. A figure far outside a band is worth a question before you pay.
Sizing an inverter for a 2BHK
Watts become VA, you pick the inverter so the load sits near 70%, and the backup hours depend on whose formula you use.
What a metre of TMT bar should weigh
Weigh five bars of one size together, divide by their length, and compare. Thinner bars get a wider tolerance.
How many test cubes on slab day
IS 456 sets the number of samples by the volume of each grade. A 1,000 sq ft roof slab of about 14 m³ needs two.
Whole jobs, step by step, with a free worksheet
A system takes one complete job from the first measurement to the last payment. Each comes with a one-page worksheet to print and take to site.

Repaint your home before Diwali
Measure, pick the paint, putty and primer only where needed, then plan the room batches.
Re-tile a floor or bathroom
Tap-test the old floor, decide over or out, then order tiles, adhesive and grout.
Rooftop solar for a 3BHK
12 months of bills, the roof, the size, the backup question and three quotes, line by line.
Inverter backup for a 2BHK
List what you'll run in a cut, then size the inverter and the battery for the hours you need.
Buying a plot: check the area
Before you buy a plot, turn katha, decimal, gunta, marla or gaj into sq ft, tape the four sides and a diagonal, and compare with the record. Free check sheet.
Slab casting day
Plan slab casting day in India: concrete and cement bags from the drawings, checks the night before, a continuous pour, cube samples, curing and strip dates.
What the weather and the calendar change
days to Diwali on 8 Nov 2026. A 2BHK repaint takes about three working days for each batch of rooms, so start this week and paint one batch of rooms at a time.
Plan the repaint →Repaint in batches of rooms
Each coat needs about 4 hours before the next, so allow about three working days a batch. A 750 sq ft 2BHK takes 18 to 20 litres.
Repaint your home before DiwaliPaint CalculatorAsk the engineer for the strip dates
IS 456's stripping times assume ordinary Portland cement at 15 °C or above. A slab poured on a cold winter day needs the engineer's own dates.
Slab curing days and propsConcrete cube test on slab dayCure slabs for at least 10 days
In dry, hot weather IS 456 asks for at least 10 days of wet curing for any cement, and 14 is recommended for blended cement.
How many days to cure a slabInverter backup for a 2BHKKeep cement dry and test the soil wet
Wrap the cement stack in polythene that closes over the top. A percolation test after an overnight soak shows how a soak pit will behave in the rains.
Check cement bags on deliveryPercolation test for a soak pitSix questions, answered from the guides
Which MCB for a 1.5-ton AC?
Read the outdoor unit's nameplate, not the tonnage. A plate showing 10.5 A maximum needs a 16 A MCB, the next standard size up (6, 10, 16, 20, 25, 32 A).
Full guide →How do I count a brick load?
Have it stacked 50 long, 10 high and 4 wide as it comes off the truck. That is 2,000 bricks a stack, and you can count stacks by eye.
Full guide →How old can cement be?
The bag shows its packing week. The best-before is three months after that. Older cement gets retested before use; it isn't thrown away.
Full guide →Is that sand truck really 1 brass?
Measure the inside length and width of the body and the load depth at six points, before it tips. cft ÷ 100 = brass.
Full guide →How many litres does my sump hold?
Inside length × inside width × water depth, in metres, × 1,000. Measure the water depth up to the overflow, not to the roof slab.
Full guide →How many tiles for a 12 × 10 ft room?
In 600 × 600 mm tiles with skirting, 38 tiles, 10 boxes of 4. That includes 10% for a straight lay. Ask for one batch and shade code.

Formula and wastage on every calculator
You see the sum, the wastage percentage and each assumption, so you can redo it by hand.
Rates with a month, codes with a clause
Cost rates are ranges dated to the month they were checked. Quantities cite the Indian Standard and clause they come from.
Planning only, and it says so
Structural sizes, steel in members, foundations and approvals always go to a licensed engineer. The systems and guides say so on the page.
Common questions
What is NineClip Build?
A free set of calculators, step-by-step systems and site guides for people building or fixing a home in India. It covers cost, cement, steel, bricks, concrete, plaster, tiles, paint, wiring, water tanks, septic tanks and rooftop solar.
Is it free? Do I need to sign up?
It is free and there is no account. The calculators run in your browser, so the sizes and amounts you type stay on your device.
Where do the rates and numbers come from?
Cost rates are ranges with a month on them (the current set is as of Jul 2026) and a named source. Quantities come from CPWD's Analysis of Rates and Indian Standards such as IS 456, IS 1786 and IS 2470, each cited with its clause on the page that uses it. How we source rates.
Can I build from these numbers?
Use them to plan, compare quotes and check deliveries. Structural sizes, steel in members, foundations and approvals always need a licensed engineer. The systems and guides say so on the page.
Do the rates change by city?
Yes. The calculators use a national average for now, and metros usually run 20 to 30% above tier-2 cities. Get three local quotes in the same cost lines before you fix a budget.
