Plan a house construction budget: the 7-step system
Take a 1,000 sq ft house from a rough figure to a line-by-line budget you can hold three contractors to, using our calculators and one printable page.
By Bulan Sarkar · Updated
A standard-quality 1,000 sq ft house costs about ₹15 to 25 lakh to build in India (rates as of Jul 2026), before land, approvals, interiors and the boundary wall. Plan it in seven steps: fix the built-up area, pick a quality tier, split the figure into CPWD's 13 cost lines (about 80% materials and 20% labour), check steel and cement quantities, get three quotes in the same 13 lines, add what sits outside the contract, then set when each line gets paid.

The decision: plan the budget yourself?
Yes, if you are building an independent house and will compare contractors. Fixing the area, splitting the budget and checking quotes needs only a calculator and this page.
If you are buying a builder flat, or signing a fixed-price turnkey contract, you do not need the 13-line split. Check the rate per sq ft and the list of what is excluded, and stop there.
Column, beam, slab and foundation sizes, and the steel in them, must come from a licensed structural engineer's drawings. Plan approval goes through an architect or engineer registered with your local body. Our figures are estimates for planning only.
The steps, in order
Fix the built-up area
Have ready:plan sketch or drawingplot sizenumber of floors
Add up the covered area of every floor, walls included. This is the built-up area, and every rate per sq ft in India is quoted on it. It is not the plot area and not the carpet area. If your land papers give the plot in bigha, katha or gunta, convert it first, then check how much of it the plan covers.
Pick a quality tier and get the base figure
Have ready:built-up areafinish choices (tiles, fittings)
Basic finishes run ₹1,200 to 1,500 per sq ft, standard ₹1,500 to 2,500 and premium ₹2,500 to 4,500 (Jul 2026). Multiply by your area. For 1,000 sq ft at standard that is ₹15 to 25 lakh. Write down the low and high ends, not one number.
Split it into CPWD's 13 cost lines
Have ready:base figurecontingency % you want
CPWD tracks building costs with 13 inputs whose weights add to 100. Labour is 20, steel 19.5, cement 14.5, bricks 8, aggregate 6.5 and sand 3. Doors and windows take 7, flooring 5 and paint 3. Lights and fans take 4.5, wires 4, pipes 2.5 and the pump set 2.5. The planner turns your figure into rupees for each line and prints it.
Check the big quantities
Have ready:built-up areacontractor's BOQ if you have one
Steel and cement alone are 34% of the budget. Thumb rules for a framed house are 3 to 4 kg of steel and 0.35 to 0.5 bags of cement per sq ft, wastage included. For 1,000 sq ft that is 3 to 4 tonnes of steel and 350 to 500 bags. If a quote is far outside this range, ask why. The engineer's drawings decide the final figure.
Get three quotes in the same 13 lines
Have ready:printed 13-line splitsame drawings for every contractor
Give each contractor the same drawings and ask them to price against your 13 lines. Then compare them line by line. A quote that looks cheap but has no line for the pump, wiring or doors has left those out, and you will pay for them later.
Add what sits outside the contract
Have ready:approval fee estimatearchitect or engineer feeboundary wall length
The ₹/sq ft bands leave out land, plan approval fees, architect or engineer fees (often 2 to 5% of cost), interiors and the boundary wall. List each one with its own figure. Then add a contingency: the planner uses 5%, and 10% is safer if the drawings are not final.
Set the money calendar
Have ready:the 13-line budgetrough work schedule
Money goes out in the order of work. Steel, cement, aggregate, sand, bricks and most of the labour are spent in the structure stage. Doors and windows, flooring, paint, wiring, fittings and the pump come at the end, after any overrun in the structure stage has already been paid. Mark on the worksheet which month each line is due, and keep the contingency for the finishing stage.
What goes wrong
Variants: what changes the steps
Ground floor now, upper floor later
The foundation and columns must be designed for the future floor today. That is an engineer's decision, and it adds to this year's structure lines even though you build less area.
Labour-only contract
You buy the materials yourself, about 80% of the budget on CPWD weights, and the contractor's quote covers only the labour line. Track every material delivery on the worksheet.
Basic, standard or premium finishes
The structure lines barely move between tiers. The difference sits in flooring, doors and windows, fittings and paint, so tier is decided in step 2 and checked again in step 5.
Big city or small town
Our bands are national ranges. Local quotes can sit at either end, so treat step 5 as the real price and step 2 as the sense check.
Tips and tricks
- Print the 13-line split and hand the same sheet to every contractor. Quotes in your format are quick to compare.
- Write the month next to every rate you note down. Steel and cement prices move monthly, and a quote older than three months needs a fresh check.
- Keep the contingency in a separate account or envelope, outside the contractor's figure, and spend it only on the finishing stage.
- Ask for the bar bending schedule from the engineer before you order steel. It turns the 3 to 4 kg per sq ft thumb rule into exact bar lengths.
- Keep every bill, weighbridge slip and cement lot date in one folder. When a line runs over, the folder tells you why.
What we would do
For a first house of about 1,000 sq ft we would budget at the middle of the standard band, ₹2,000 per sq ft or about ₹20 lakh, add 7% for contingency, and ask three contractors to quote against the 13 lines. We would tie each payment to a stage you can see finished, and hold the contingency back for flooring, wiring and fittings, which come last.
