Diaspora House-Build Budget Calculator (Nepal)
Plan a realistic budget to build a house in Nepal from abroad — base cost plus remote-management overhead and contingency, with the total in NPR and your home currency, split into stage-wise payments.
Stage-wise payment plan
| stage | percent | amount |
|---|---|---|
| Substructure (excavation, foundation, DPC) | 12% | NPR 7,56,000 |
| RCC frame (columns, beams, slabs) | 33% | NPR 20,79,000 |
| Masonry & plaster | 18% | NPR 11,34,000 |
| Finishing (flooring, paint, joinery) | 25% | NPR 15,75,000 |
| MEP services (plumbing, electrical, sanitary) | 12% | NPR 7,56,000 |
How this works
A remote build costs more than an on-site one. We start from the base cost and add the two extras a diaspora owner really carries:
baseCost = area × ratePerSqft
remoteOver = baseCost × remoteOverheadPct / 100
contingency = baseCost × contingencyPct / 100
totalNPR = baseCost + remoteOver + contingency
homeTotal = totalNPR / fxRate (NPR per 1 home unit)The total is then split into standard construction stages so you can release money against verified progress instead of in one lump sum.
Worked example
A 1,500 sq.ft standard-finish house at NPR 3,500/sq.ft, with 8% remote overhead and 12% contingency:
- Base cost = 1,500 × 3,500 = NPR 52,50,000
- Remote overhead (8%) = NPR 4,20,000
- Contingency (12%) = NPR 6,30,000
- All-in total = NPR 63,00,000 (≈ NPR 4,200/sq.ft)
At 133 NPR per unit of home currency, that is roughly 47,368 in your home currency — the number to actually plan and fund.

FAQ
How is a diaspora build budget different from a normal estimate?
The materials and labour cost the same, but building remotely adds overhead: extra site visits, a supervising engineer or clerk of works, coordination time, and coordination across time zones. This calculator starts from the normal base cost (area × rate) and layers a remote-management overhead and a contingency on top, so the figure you plan for reflects the real cost of building from abroad.
What rate per sq.ft should I enter?
Use a current per-sq.ft rate for your quality tier — basic, standard, or premium finishing — from a local quote or a recent estimate. Rates move with material prices and location, so start from a real number rather than an old figure. Our cost-per-sq.ft guide and the RCC house cost calculator can help you pick a realistic base.
What remote-management overhead should I use?
Many diaspora owners budget around 5–10% of the base cost for the extra supervision, site visits, and coordination that a remote build needs. The exact figure depends on how often you can visit, whether you hire an independent supervising engineer, and how far the site is from a city. Adjust the percentage to match your own arrangement.
How much contingency should I keep?
A 10–15% contingency on the base cost is sensible for any Nepal project, and remote builds sit at the higher end because problems are slower and harder to fix from abroad. Keep the contingency as a separate reserve, not part of the working budget, so it is genuinely available when a surprise appears.
Does the home-currency figure use a live exchange rate?
Yes. Choose the country you live in and the calculator auto-fills the current live exchange rate for your currency, so the 'what you need in your currency' figure reflects today's market. The rate stays editable — type your bank's rate to test a specific scenario — and if the live feed is briefly unavailable it uses a saved estimate and says so.
What are the stage percentages used for?
The stage split (substructure, RCC frame, masonry and plaster, finishing, and MEP services) turns the total into indicative amounts per construction stage. Use these to plan staged payments — releasing money against verified progress rather than in one lump sum — which is the safest way to fund a build you cannot supervise daily.
