A typical 16-inch stand fan is rated 50 to 65 W, so it uses at most about 0.4 to 0.5 kWh over an 8-hour night: about ₱6 to ₱8 at Meralco’s October 2026 rate of ₱15.06 per kWh, or roughly ₱181 to ₱235 a month if it runs every night. A DC inverter fan rated 35 W costs about half that.
Short answer: watts ÷ 1,000 × hours × your rate per kWh. A 65 W fan running 8 hours a night for a month uses 15.6 kWh, about ₱235. A 35 W DC fan uses 8.4 kWh, about ₱127. These are ceilings: the rated wattage is the most the fan draws, at top speed.
Electric fan electricity cost by wattage
Find the wattage on the fan’s label or box, then read across. All figures use Meralco’s October 2026 rate of ₱15.06 per kWh.
| Rated power | 1 hour | One 8-hour night | A month, 8 hours a night | A month, 12 hours a day |
|---|---|---|---|---|
| 35 W | ₱0.53 | ₱4.2 | ₱127 | ₱190 |
| 50 W | ₱0.75 | ₱6.0 | ₱181 | ₱271 |
| 65 W | ₱0.98 | ₱7.8 | ₱235 | ₱352 |
| 90 W | ₱1.36 | ₱10.8 | ₱325 | ₱488 |
| 145 W | ₱2.18 | ₱17.5 | ₱524 | ₱786 |
| 250 W | ₱3.77 | ₱30.1 | ₱904 | ₱1,355 |
Most home fans fall in the first three rows. The 145 W and 250 W rows are 20 to 26-inch industrial fans, which use three to four times as much as a household stand fan.
What fans sold in the Philippines actually draw
We read all 128 in-stock fan listings at Western Appliances on 21 October 2026. The pattern by type, with examples (price that day):
| Type | Typical rating | Examples |
|---|---|---|

| 18-inch stand fan | 70 to 100 W | Tough Mama NTMSF18P 70 W (₱1,640), Asahi CF833 80 W (₱2,890), Asahi PF840 90 W (₱2,480), Asahi WF841 100 W (₱3,080) |
| DC inverter fan | 35 to 50 W | Asahi DC-6082 35 W (₱4,700), Asahi WF630R wall fan 35 W (₱3,800), Kolin KF18SMBDC 44 W (₱3,620), Iwata AS24X1 50 W (₱5,200) |
| Tower fan | 28 to 75 W | Asahi TF007 28 W (₱7,100), Imarflex IF630M 50 W (₱2,580), Hanabishi HTOWF2000 60 W (₱4,600), Asahi TF006 75 W (₱3,900) |
| Desk fan | 35 to 55 W | Asahi EF8 8-inch 35 W (₱1,280), Tough Mama NTMBF12A 45 W (₱1,040), Asahi EF121 12-inch 55 W (₱1,900) |
| Industrial fan (20 to 30-inch) | 145 to 280 W | Asahi PF2010 145 W (₱3,600), Iwata Tornado 24 200 W (₱5,600), Asahi PF2601 250 W (₱8,300) |
Many listings, including most of Hanabishi’s and KDK’s, do not state a wattage at all. If yours is one of them, look for the rating plate on the motor housing or the base.
Is a DC inverter fan worth it?
It saves money, slowly. Take two 16-inch Asahi stand fans on Western Appliances’ site on 21 October 2026: the DC-6082 (35 W, ₱4,700) and the BG620 (65 W, ₱2,140). Run each 8 hours a night at top speed and the DC fan saves about ₱108 a month. The extra ₱2,560 pays for itself in about 24 months; at 12 hours a day, about 16 months.
The other reasons to buy one are not about the bill: DC fans usually have more speed steps (Asahi’s has 12), a remote and a timer, and they tend to run more quietly. If you only use a fan a few hours a day, a standard fan is the cheaper buy.
How to keep the cost down
- Use a lower speed. The rated wattage is at top speed; lower settings draw less.
- Use the timer. Set it to switch off after you fall asleep, instead of running all night.
- Buy the size you need. An 18-inch fan rated 90 W uses half as much again as a 16-inch fan rated 60 W.
- Check your own rate. Divide the total on your bill by the total kWh and put it into our electricity cost calculator.
The formula, and the rate we use
Divide the fan’s watts by 1,000, multiply by the hours it runs, and you have the kWh; multiply by your rate for the cost. We use ₱15.06 per kWh, Meralco’s overall rate for a typical household in October 2026 (₱15.0615, as announced by Meralco). Rates change every month.
How we worked this out: wattages are the figures printed on Western Appliances’ listings on 21 October 2026, and on Asahi’s own page for the DC-6082. The costs are the arithmetic above. We have not measured these fans with a meter. Read how we test.

Frequently asked questions
How much electricity does an electric fan use per hour?
Its rated wattage divided by 1,000: a 65 W stand fan uses up to 0.065 kWh an hour, about ₱0.98 at Meralco’s October 2026 rate. A 35 W DC fan uses about ₱0.53 an hour.
How much is an electric fan per month in the Philippines?
Running 8 hours a night: about ₱181 to ₱235 for a typical 50 to 65 W stand fan, and about ₱127 for a 35 W DC fan, at ₱15.06 per kWh. These are ceilings at top speed.
Does a DC inverter fan save electricity?
Yes. A 35 W DC fan uses about half the power of a 65 W standard fan: about ₱108 a month less at 8 hours a night. The higher price takes about two years to pay back at that use.
Which uses more electricity, a stand fan or a tower fan?
It depends on the model, not the shape. The tower fans we found are rated 28 to 75 W and 16-inch stand fans 50 to 65 W, so check the wattage on the label.
