Inverter Charging Cost
Monthly and yearly electricity cost from wattage, hours and duty cycle — with savings tips.
Your backup isn't free: charging losses mean every stored unit costs ~1.25 grid units. A daily-cycling inverter bank adds ₹300–500/month — visible only when you calculate it. Enter your appliance's actual wattage (nameplate or energy-label), daily hours and your top-slab tariff for the honest monthly figure.

Frequently asked questions
How do I calculate an appliance's electricity cost?+
kWh/day = watts × hours × duty-cycle ÷ 1000; cost = kWh × your marginal tariff. The duty cycle is the honest part — a 1,700 W AC at 70% duty actually draws ~1.2 kW average, while a 2,000 W geyser heats at 100%. This calculator bakes that in per appliance.
Why use the top-slab rate instead of the average?+
Because any appliance you're evaluating ADDS units at the top of your consumption — at the highest slab you touch. Pricing a new AC at the average rate understates its real bill impact by 20–40% in most slab structures; marginal pricing is decision-grade.
Which home appliances cost the most to run?+
In typical Indian homes: air conditioners dominate (₹1,500–4,000/month each in season), then geysers (₹400–900), refrigerators (₹300–450, but 24×7×12 months), and the silent always-on cluster (routers, set-top boxes, standby ≈ ₹200–350). The shock is rarely the appliance — it's the hours.
Is the Inverter Charging Cost's saving tip really worth it?+
The tips target each appliance's dominant loss — thermostat degrees for ACs, timers for geysers, duty discipline for pumps. Individually they're 5–30% of that appliance's cost; together across a household they routinely cut 15–25% off the bill, at near-zero spend. The math here lets you verify each claim.
