How Much Does It Cost to Run a Dehumidifier in India? (2026)

A dehumidifier runs like a small air conditioner, and people often leave it on for most of the day in damp basements. That combination of moderate wattage and long hours makes it a surprising line item on the bill.

A typical dehumidifier (400 W) costs ₹2.40 per hour, or about ₹720.00 per month at 10 hours a day in India. Expensive to run

Electricity price region Hours used per day

Wattage	Per hour	Per day	Per month	Per year
Low (250 W)	₹1.50	₹15.00	₹450.00	₹5,475
Typical (400 W)	₹2.40	₹24.00	₹720.00	₹8,760
High (700 W)	₹4.20	₹42.00	₹1,260	₹15,330

Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 10 h/day ≈ 1,460 kWh per year.

In India, with electricity at ₹6.00 per kWh (source: Typical urban domestic slab rate; national average ≈ ₹5.5/unit FY2025-26, 2026-04), a typical dehumidifier costs ₹2.40 per hour and about ₹8,760 per year at 10 hours a day. Each ₹1.00 of electricity buys roughly 0.4 hours of use.

How to lower the cost of running a dehumidifier

Set the humidistat to 50 percent. Lower settings make the unit run far longer for little benefit.
Close windows and doors in the room being dried.
Empty the tank promptly or use continuous drain so the unit does not sit idle.
Look for the Energy Star rating, which measures litres removed per kWh.

In standby it draws about 1 W, which adds roughly 9 kWh (₹52.56) per year if it is never unplugged.

Frequently asked questions

How much does it cost to run a dehumidifier 24/7?

A 400 watt unit uses 9.6 kWh a day if it never cycles off. With a humidistat, real use is usually half that.

Does a dehumidifier heat the room?

Yes, slightly. All the electricity it uses ends up as heat, which can help in a cold basement.

Are desiccant dehumidifiers cheaper to run?

No, they typically use more electricity, but they work better in cold rooms.
