Electrical Points Estimator

How this estimator works

1. Points are counted per room from a fixed schedule, published in the table below and based on how Indian families actually use rooms rather than on a minimum code.
2. Bedrooms are 11 points each: two bedside sockets with switches, one for the AC controller, two light points, one fan, a wardrobe light, a TV or study socket, and a spare.
3. The kitchen is 14 because every appliance needs its own socket at counter level, and the chimney, the hob igniter and the water purifier all need dedicated ones.
4. Cost = points × rate × smart factor, plus AC points at ₹1,575 and the distribution board.
5. Smart switching multiplies the point rate — 1.35 for the living room and master only, 1.90 for a whole home — because a smart module costs more than a switch and the wiring topology changes.
6. AC points are counted separately and are not multiplied by the smart factor.

The points people wish they had added

• Both sides of the bed, at 24 inches height. Not one socket behind the headboard. Two phones, two lamps, and nobody crawling under the bed.
• Six sockets along the kitchen counter, spaced so two appliances can run without an extension cord. This is the single most under-provisioned run in every Indian flat.
• A socket inside the wardrobe loft for a dehumidifier, and one inside the TV unit for the set-top box and router so no cable is visible.
• One at the entry console, for charging keys, a phone and whatever the household drops at the door.
• A weatherproof socket on the balcony, for a vacuum, plants lights or a pressure washer, in a 16 A IP-rated enclosure.
• Data points, not just Wi-Fi. One hard-wired point per bedroom and two in the living room costs ₹920 each now and cannot be retrofitted without chasing walls.

What the estimate assumes about the wiring itself

The point rate covers concealed conduiting in the wall, FR-grade copper cable back to the distribution board, the modular switch and plate, and the making good of the chase. What it assumes is a rewire or a new flat. If you are adding points into an existing circuit in an old Mumbai building, the honest answer is often that the existing wiring will not take them — aluminium cable, no earth, and a board with rewireable fuses is still common in buildings from before 1990.

In that situation adding points is not the job. A full rewire is, and it costs roughly the same per point but includes a new board, a residual current device and a proper earth. We would rather tell a client that at survey stage than wire fifteen new points onto a circuit that should not be carrying them.

Point, AC-point and distribution-board rates here are the ones Greenbox invoiced on completed flats, taken off the measured electrical schedules and held at October 2026. Smart modules and the fittings themselves are supplier prices and sit outside that set. We publish the rest so the arithmetic can be audited rather than trusted. Treat the output as a planning figure: accurate enough to brief a landlord, a bank or a family, and not accurate enough to sign a contract against.

What this tool does not cover

• Chasing and making good in an existing flat, at ₹180–320 per point over and above the point rate.
• Light fittings themselves — see the downlights calculator and the LED strip calculator.
• Inverter or UPS wiring as a separate circuit, plus the battery location and its ventilation.
• Earthing improvement, which in an older building is frequently the most important item on the list.
• Society permissions and the electrician's licence requirements for work on the incoming supply.
• For overall lighting levels rather than point counts, see the lumens calculator.
