3 BHK Electrical Wiring Cost Calculator
Use this prefilled 3 BHK plan as a starting point for a new flat or independent floor and adjust every room and appliance point before comparing contractor quotes.
This is a starting configuration, not a fixed claim about every 3 bhk home. Change any input to match the actual floor plan.
1. House size & layout
Enter built-up area and room counts. You can change every assumption.
Advanced floor-by-floor plan
Turn this on when different floors have different rooms or areas.
Planning budget
Indicative material + labour range, not a contractor quote. Final cost depends on floor plan, brands, concealed/surface routing, DB, earthing and local labour.
Estimated wiring quantities
Quantity is a planning range only. A signed floor plan and DB position are needed for a purchase-ready BOQ.
Custom contractor rates
If you already have local quotations, enter them here. The tool will keep its benchmark range and show your own contractor-based total separately.
Editable material & labour rates
Enter current dealer/electrician rates from your city. No default market price is assumed.
Floor-wise planning
A simple equal-area split for early budgeting. Adjust your room counts above if floors differ materially.
| Floor | Approx. area | Approx. points | DB allowance |
|---|---|---|---|
| Ground floor | 1,400 sq ft | 78 | 1 |
2. Room-based electrical point schedule
Use this as a discussion checklist with your electrician.
3. Planning BOQ (Bill of Quantities)
Use this as a first-pass purchase/contractor checklist. Final quantities require the actual floor plan and DB locations.
| Use | Planning cable class | Estimated length | Note |
|---|---|---|---|
| Lighting / fan circuits | 1.5 sq mm class | 497–827 m | Planning allocation only; final size/load must be verified. |
| General socket circuits | 2.5 sq mm class | 390–649 m | Planning allocation only; circuit load and route determine final size. |
| AC / geyser / heavy loads | 4–6 sq mm class | 213–354 m | Dedicated circuit sizing must be verified for each appliance. |
| Sub-main / DB feeders | Design-dependent | 83–138 m | Depends on sanctioned load, floor DBs and route length. |
Room-wise baseline
AC, geyser and extra heavy points are added separately above, so this room baseline is not the final total by itself.

Safety & estimate note
This calculator is for budgeting and point planning. Cable size, protection devices, earthing, circuit segregation and final quantities must be verified from the actual load and floor plan by a qualified electrician/electrical professional before purchase or installation.
Start from a common Indian home size
These presets use the same calculator engine and remain fully editable.

Keep installation costs separate from electricity bill benefits
Wiring and cable planning concern installation work. A recurring household bill subsidy does not automatically pay for that work or approve a cable size. Check the state-wise household electricity benefits guide when planning ongoing costs.
For your location, review PSPCL domestic subsidy conditions in Punjab, MP Atal Graha Jyoti bill relief or Delhi domestic subsidy eligibility. Eligibility and installation estimates are separate decisions.
