How the budget is calculated
Formula
Midpoint = area per floor × floors × your rate × quality factor, plus contingency. The low and high estimates apply your range percentage either side of that midpoint.
For 1,000 sq ft, one floor, the ₹2,268/sq ft CPWD starting reference, standard quality and 10% contingency, the midpoint is ₹24,94,800. A ±10% range is ₹22,45,320 to ₹27,44,280.
What to check
Confirm built-up area, local specifications, site conditions and the scope covered by your rate. The cost split is illustrative; a measured BOQ is needed for detailed purchasing and pricing.
Where does the starting rate come from?
It starts with the dated CPWD Plinth Area Rate for an RCC framed home of up to six storeys. Treat that as a reference, then replace it with a recent local rate for your scope.
Can I use this as my BOQ?
No. This is an early area-based range. Once measurements are available, build the job from measured work items in the advanced BOQ.
How does the quality adjustment affect the cost?
It only raises or lowers the rate for a planning scenario. It does not choose products, define workmanship or set a construction standard.
