Smart Meter Recharge Calculator

How long will a ₹500 recharge actually last on your prepaid smart meter? Pick your DISCOM and monthly usage — we run it through the real tariff (slab rates, fixed charges, FPPA, duty) and show your daily burn rate, how many days each recharge buys, and the ideal monthly recharge amount.

How this calculator works

Most "units × rate" estimates get prepaid maths wrong, because a prepaid balance doesn't only pay for energy. Every day your meter also deducts a share of the fixed charge, FPPA (fuel surcharge) and electricity duty. This tool computes your full monthly bill with the same engine as our bill calculator — slab-wise rates and all — then divides by 30 to get the true daily burn rate your balance drains at.

Smart meter help

Estimates assume a 30-day month and your DISCOM's primary domestic tariff; actual deduction rules (daily fixed-charge apportioning, rebates, seasonal usage) vary by DISCOM. Treat this as a planning guide and verify against your meter app's balance history.
