How we calculate

Common Indian practice: 1.5 sq mm for lights and fans, 2.5 sq mm for 6A sockets, 4 sq mm for 16A power and AC points, with an earth wire on every circuit (1, 1.5 and 2.5 sq mm).
Each point needs phase + neutral + earth over the average run; 16A and AC runs are taken as 30% longer (dedicated circuits). Plus 10% for joints and wastage.
Electricians who loop circuits use less. If a quote has far more coils than this, ask for a point-wise wiring plan.
