Building Estimating Calculator Nepal | Plinth Area Rate
Quick building estimate for Nepal homes using plinth area, storeys, and rate per sq ft or m². Ideal first budget for residential construction planning.
How this works
total built-up = plinth area × storeys base cost = built-up × rate × quality factor total = base + contingency% + external works%
Worked example
1,000 ft² plinth × 2.5 storeys = 2,500 ft². At NPR 3,500/ft² with 10% contingency and 5% external works, the envelope budget is shown instantly.
FAQ
What is building estimating in the Nepali market?
Homeowners often use a plinth-area rate method: total built-up area × rate per sq ft or m². This calculator follows that planning approach and adds contingency and external works allowances.
What rate should I enter?
Use a current local rate for the finish level you want (economy / standard / premium). Rates change with steel, cement, labour, and location — update them before relying on the total.
Is this a BOQ?
No. A BOQ itemises materials and labour. This is a fast budget envelope. For detailed quantities, use the BOQ tools and material calculators.
Why add contingency?
Price swings, design changes, and hidden site works are common. 8–12% contingency is a typical planning buffer for residential work.
Does quality factor replace the rate?
It multiplies your base rate so you can stress-test economy vs premium without retyping rates. You can also leave it at 1.0 and put the full rate in the rate field.
