Estimate your Punjab home electricity bill from the official tariff: slabs, fixed charge, surcharges, duty and subsidy.
Quick answer
PSPCL bills homes every two months. Up to 600 units in two months, the bill is zero under the Punjab free-power rule. Above 600, a general household pays for all units: the first 600 at ₹3.85 to ₹5.00 a unit depending on load, the rest at ₹7.05, plus a fixed charge of ₹50 to ₹100 per kW on 80% of the load.

The 600-unit cliff
For general households, crossing 600 units in a billing cycle turns a zero bill into a bill for every unit used. Try 600 and 601 units in the calculator to see the jump.
