Construction Phase Budget Calculator (Nepal)
Split your total house-construction budget across the phases of the build — foundation, structure, masonry, finishing and more — in NPR and your home currency, so you know how much cash is needed at each stage.
Phase-by-phase budget
| phase | percent | amount | in USD | cumulative |
|---|---|---|---|---|
| Site preparation & excavation | 3% | NPR 1,80,000 | $1,184 | NPR 1,80,000 |
| Foundation & footing | 12% | NPR 7,20,000 | $4,737 | NPR 9,00,000 |
| Plinth & DPC | 5% | NPR 3,00,000 | $1,974 | NPR 12,00,000 |
| Superstructure (columns, beams, slabs) | 25% | NPR 15,00,000 | $9,868 | NPR 27,00,000 |
| Brick masonry | 10% | NPR 6,00,000 | $3,947 | NPR 33,00,000 |
| Plastering & punning | 8% | NPR 4,80,000 | $3,158 | NPR 37,80,000 |
| Roofing & waterproofing | 4% | NPR 2,40,000 | $1,579 | NPR 40,20,000 |
| Doors & windows | 8% | NPR 4,80,000 | $3,158 | NPR 45,00,000 |
| Electrical wiring | 5% | NPR 3,00,000 | $1,974 | NPR 48,00,000 |
| Plumbing & sanitary | 6% | NPR 3,60,000 | $2,368 | NPR 51,60,000 |
| Flooring & tiling | 8% | NPR 4,80,000 | $3,158 | NPR 56,40,000 |
| Painting & finishing | 4% | NPR 2,40,000 | $1,579 | NPR 58,80,000 |
| Boundary, gate & external | 2% | NPR 1,20,000 | $789 | NPR 60,00,000 |
How this works
Each phase gets a share of the total based on an indicative weighting for the chosen structural system:
phaseAmount = totalCost × phasePercent / 100The cumulative column shows how much you will have spent by the end of each phase — the cash-flow curve you need to fund the build. If you earn abroad, pick your country to see each phase in your home currency at the live rate.
Worked example
An RCC house with a total budget of NPR 60,00,000:
- Foundation & footing (12%) = NPR 7,20,000
- Superstructure — columns, beams, slabs (25%) = NPR 15,00,000
- Finishing, flooring, painting combined ≈ NPR 12,00,000
Switch the system to steel or prefab to see how the split shifts toward the frame and panels.

FAQ
What is a construction phase budget?
It is a breakdown of your total house-construction cost across the physical stages of the build — foundation, structure, masonry, roofing, finishing, and so on. It shows where your money goes and, just as importantly, how much cash you need to have ready by each stage, which is essential for planning payments and remittances.
Why do the percentages change with the structural system?
Because the cost distribution is genuinely different. An RCC house spends heavily on columns, beams, and slabs; a light-gauge steel house shifts cost into the frame and wall panels; a prefab panel house concentrates cost in the panels and fittings. The calculator uses a separate weighting table for each system so the split reflects how that system is actually built.
Are these percentages exact for my house?
No — they are indicative planning figures for a typical Nepali residential build. Your actual split depends on your design, specification, site, and finishing choices. Use these to plan cash flow and sequence payments, then refine against a real bill of quantities (BOQ) from your engineer or contractor.
How do I use the phase budget with a payment schedule?
The phase budget tells you the cost of each stage; the payment schedule turns that into what you release to the contractor and when. Pair this tool with the House Construction Payment Schedule Calculator so you pay against verified stage completion rather than in one lump sum.
Can I see the phase budget in my own currency?
Yes. The base amounts are in NPR, but if you live abroad you can pick your country and the calculator converts the total and each phase into your home currency at the current live exchange rate. The rate is editable, so you can also enter your bank's exact rate. For a full remote budget with overhead and contingency, use the Diaspora House-Build Budget Calculator.
